Definitions
- the present invention is in the field of novel chalcone derivatives, pharmaceutical compositions and methods for treating a variety of diseases and disorders, including inflammation and cardiovascular disease.
- Adhesion of leukocytes to the endothelium represents a fundamental, early event in a wide variety of inflammatory conditions, autoimmune disorders and bacterial and viral infections.
- Leukocyte recruitment to endothelium is mediated in part by the inducible expression of adhesion molecules on the surface of endothelial cells that interact with counterreceptors on immune cells.
- Endothelial cells determine which types of leukocytes are recruited by selectively expressing specific adhesion molecules, such as vascular cell adhesion molecule-1 (VCAM-1), intercellular adhesion molecule-1 (ICAM-1), and E-selectin.
- VCAM-1 vascular cell adhesion molecule-1
- ICAM-1 intercellular adhesion molecule-1
- E-selectin E-selectin.
- VCAM-1 binds to the integrin VLA-4 expressed on lymphocytes, monocytes, macrophages, eosinophils, and basophils but not neutrophils. This interaction facilitates the firm adhesion of these leukocytes to the endothelium.
- VCAM-1 is an inducible gene that is not expressed, or expressed at very low levels, in normal tissues.
- VCAM-1 is upregulated in a number of inflammatory diseases, including arthritis (including rheumatoid arthritis), asthma, dermatitis, psoriasis, cystic fibrosis, post transplantation late and chronic solid organ rejection, multiple sclerosis, systemic lupus erythematosis, inflammatory bowel diseases, autoimmnune diabetes, diabetic retinopathy, rhinitis, ischemia-reperfusion injury, post-angioplasty restenosis, chronic obstructive pulmonary disease (COPD), glomerulonephritis, Graves disease, gastrointestinal allergies, conjunctivitis, atherosclerosis, coronary artery disease, angina and small artery disease.
- arthritis including rheumatoid arthritis
- asthma including rheumatoid arthritis
- dermatitis including dermatitis, psoriasis, cystic fibrosis, post transplantation late and chronic solid organ rejection
- multiple sclerosis systemic lup
- Coronary heart disease primarily as a result of atherosclerosis, remains the leading cause of death in industrialized countries.
- Atherosclerosis is a disease characterized by vascular inflammation, deposition of lipids in the arterial vessel wall and smooth muscle cell proliferation resulting in a narrowing of the vessel passages.
- atherosclerotic lesions can become unstable resulting in plaque rupture, thrombosis, myocardial infarction and ischemic heart disease.
- VCAM-1 expression has been shown to inhibit atherosclerosis in several animal models (Sundell et al., Circulation, 100: 42, 1999).
- a monoclonal antibody against VCAM-1 has also been shown to inhibit neointimal formation in a mouse model of arterial wall injury (Oguchi, S., et al., Arterioscler. Thromb. Vasc. Biol., 20: 1729-1736, 2000).
- Asthma which is increasing in prevalence and morbidity world-wide, is a chronic inflammatory disease characterized by lung eosinophilia and bronchial hyperreactivity.
- Eosinophils have been considered an important effector cell in the pathogenesis of asthma and other allergic diseases.
- Activated eosinophils release proteins such as major basic protein (MBP) that have been demonstrated to induce bronchial hyperreactivity, one of the defining criteria of asthma (Bousquot, et al., N. Engl. J.
- VCAM-1 is markedly upregulated on human bronchial vascular endothelium of subjects with asthma who have air flow limitation, when compared with subjects without asthma (Pilewski, et al., Am. J. Respir. Cell Mol. Biol., 12, 1-3, 1995; Ohkawara, Y., et al., Am. J. Respir. Cell Mol. Biol., 12, 4-12, 1995; Gosset, P., et al., Int. Arch. Allergy Immunol. 106: 69-77, 1995; hacken, N. H., et al., Clin. Exp.
- VCAM-1 knockout mice had fewer eosinophils and VCAM-1 expression than wildtype mice; however, administration of recombinant IL-12 at the time of ova sensitization and challenge restored lung VCAM-1 expression and eosinophilia (Wang, S., et al., J. Immunol., 166:2741-2749, 2001).
- blocking the integrin receptors for VCAM-1 have had positive effects on animal models of asthma (Rabb et al., Am. J. Respir. Care Med.
- VCAM-1 has been demonstrated to be upregulated 24 hrs after nasal allergen provocation in patients with seasonal allergic rhinitis but not in normal subjects (Braunstahl, G. J., et al., J. Allergy Clin. Immunol., 107: 469-476, 2001).
- RA Rheumatoid arthritis
- RA Rheumatoid arthritis
- the role of adhesion molecules in the pathogenesis of RA has also been well documented, and VCAM-1 expression on synovial fibroblasts is a clinical hallmark of RA (Li, P., et al., J. Immunol. 164: 5990-7, 2000).
- VLA-4/VCAM-1 interactions may be the predominant mechanism for recruitment of leukocytes to the synovium (Dinther-Janssen, et al., J. Immunol. 147: 4207-4210, 1991; Issekeutz and Issekeutz, Clin. Immunol. Immunopathol.
- Soluble VCAM-1 is higher in RA patients than in control subjects (Kolopp-Sarda, M. N., et al., Clin. Exp. Rheumatol. 19: 165-70, 2001). Soluble VCAM-1 has been shown to be chemotactic for T cells (Kitani, A., et al., J. Immun. 161: 4931-8, 1998), and in addition to being a possible diagnostic marker for RA, may contribute to its pathogenesis by inducing migration and recruitment of T cells. VCAM-1 expressed on fibroblast-like synoviocytes has also been implicated in enhanced survival of activated synovial fluid B cells (Marinova, Mutafcheia, L., Arthritis Rheum. 43: 638-644, 2000) that may further contribute to RA pathogenesis.
- VCAM-1 plays a role in SLE.
- Expression of VCAM-1 is increased on dermal vessel endothelial cells in patients with active systematic lupus erythematosus (Jones, S. M., British J Dermatol. 135: 678-686, 1996) and correlates with increased disease severity (Belmont et al., Arthritis Rheum. 37:376-383, 1994).
- VCAM-1 expression on mesangial cells in vitro can be stimulated by IL-1, TNF- ⁇ , and INF ⁇ exposure as well as by anti-endothelial cell IgG fraction and anti-DNA autoantibodies from SLE patients (Wuthrich, Kidney Int. 42: 903-914, 1992; Papa, N. D., et al., Lupus, 8: 423-429, 1999; Lai, K. N., et al., Clin Immunol Immunopathol, 81: 229-238, 1996). Furthermore, soluble VCAM-1 is higher in SLE patients than in normal subjects (Mrowka, C., et al., Clin. Nephrol.
- Acute transplant rejection occurs when the transplant recipient recognizes the grafted organ as “non-self” and mounts an immune response characterized by massive infiltration of immune cells, edema, and hemorrage that result in the death of the transplanted organ. Acute rejection occurs in a matter of hours or days and has been correlated with increased levels of VCAM-1 in tissues and in plasma (Tanio et al., Circulation, 89:1760-1768, 1994; Cosimi et al., J. Immunol. 144: 4604-4612, 1990; Pelletier, R., et al., Transplantation, 55: 315, 1992).
- VCAM-1 A monoclonal antibody to VCAM-1 has been shown to inhibit cardiac allograft rejection in mice (Pelletier, R., J. Immunol., 149: 2473-2481, 1992; Pelletier, R., et al., Transplantation Proceedings, 25: 839-841, 1993; Orosz, C. G., et al., J. Heart and Lung Transplantation, 16: 889-904, 1997) and when given for 20 days can cause complete inhibition of rejection and long-term graft acceptance (Orosz C. G., et al., Transplantation, 56: 453-460, 1993).
- Chronic graft rejection also known as allograft vasculopathy is distinct from acute transplant rejection and is a leading cause of late graft loss after renal and heart transplantation. Histologically it is characterized by concentric neointimal growth within vessels that is largely due to smooth muscle migration and proliferation. It is thought to be the result of endothelial damage brought about by several factors including: ischemia-reperfusion injury, immune complexes, hypertension, hyperlipidemia and viruses. All of these factors have been associated with induction of VCAM-1 in endothelial cells. There is also a strong correlation of soluble and tissue VCAM-1 levels with chronic rejection (Boratynska, M., Pol. Arch. Med.
- Multiple sclerosis is a common demyelinating disorder of the central nervous system, causing patches of sclerosis (plaques) in the brain and spinal cord. It occurs in young adults and has protean clinical manifestations. It is well documented that VCAM-1 is expressed on brain microvascular endothelial cells in active lesions of multiple sclerosis (Lee S. J., et al., J. Neuroimmunol, 98: 77-88, 1998). Experimental therapy of experimental autoimmune encephalomyelitis, which is an animal model for multiple sclerosis, using antibodies against several adhesion molecules, including VCAM-1, clearly shows that adhesion molecules are critical for the pathogenesis of the disease (Benveniste et al., J. Neuroimmunol.
- Diabetes mellitus is a metabolic disease in which carbohydrate utilization is reduced and that of lipid and protein is enhanced.
- Evidence has accumulated that increased levels of adhesion molecules may play a functional pathophysiological role in diabetes (Wagner and Jilma, Hormone and Metabolic Research, 29: 627-630, 1997; Kado, S., Diabetes Res. Clin. Pract., 46: 143-8, 1999). It is caused by an absolute or relative deficiency of insulin and is characterized by chronic hyperglycemia, glycosuria, water and electrolyte loss, ketoacidosis, and coma.
- Elevated circulating adhesion molecules including VCAM-1 have been detected in patients with diabetes and in experimental models of diabetes in animals (Lorini et al., Hormone Research, 48: 153, 1997; Otsuki et al., Diabetologia, 40: A440, 1997; Hart et al., FASEB J. 11:A340, 1997; Albertini et al., Diabetologia, 39: A240, 1996; Wagner et al., Diabetologia, 39: A205, 1996; Enghofer et al., Diabetologia, 39: A97, 1996; Koga M., Diabet. Med., 15: 661-667, 1998).
- peripheral vasculopathies such as diabetic retinopathy and diabetic nephropathy. It is believed that adhesion of leukocytes to the peripheral vasculature plays a central role in the vasculopathies often associated with diabetes.
- Crohn's disease also known as regional enteritis, is a subacute chronic inflammatory condition of unknown cause, involving the internal ileum and less frequently other parts of the gastrointestinal tract. It is characterized by patchy deep ulcers that may cause fistulas, and narrowing and thickening of the bowel by fibrosis and lymphocytic infiltration. Ulcerative colitis is a chronic disease of unknown cause characterized by ulceration of the colon and rectum, with rectal bleeding, mucosal crypt abscesses, inflammatory pseudopolyps, abdominal pain, and diarrhea.
- VCAM-1 reflects the grade of intestinal inflammation in patients with Crohn's disease or ulcerative colitis (Jones, et al., Gut, 36: 724-30, 1995; Goggins et al., Gastroenterology, 108: A825, 1995; Goeke and Manns, Gastroenterology, 106: A689, 1994; Goeke et al., J. Gasterokenterol. 32:480-486, 1997; Loftus et al., Gastroenterology, 108: A684, 1995; Tahami et al., Gastroenterology, 118: A344, 2000). Antibodies to VCAM-1 have been shown to ameliorate experimentally-induced colitis in mice (Soriano, A., Lab. Invest. 80: 1541-1551, 2000).
- Psoriasis is a chronic skin disease characterized by erythematous scaling plaques as a result of keratinocyte hyperplasia, influx of immune cells and endothelial activation (Nickoloff, B. J., et al., J. Invest. Dermatol., 127: 871-884, 1991).
- VCAM-1 is upregulated in psoriatic skin as compared to normal skin (Groves, R. W., J. Am. Acad. Dermatol., 29: 67-72, 1993; Uyemura, K., et al., J. Invest. Dermatol. 101: 701-705, 1993) and levels of circulating VCAM-1 correlate with disease activity (Schopf, R. E., Br. J. Dermatol., 128: 34-7, 1993).
- linoleic acid linolenic acid, arachidonic acid, linoleyl hydroperoxide (13-HPODE) and arachidonic hydroperoxide (15-HPETE) induce cell-surface gene expression of VCAM-1 but not ICAM-1 or E-selectin.

Abstract
Description
- This patent application claims priority to U.S. Provisional Patent Application Ser. No. 60/342,034 filed Dec. 19, 2001 and U.S. Provisional Patent Application Ser. No. 60/386,482 filed Jun. 5, 2002.
- The present invention is in the field of novel chalcone derivatives, pharmaceutical compositions and methods for treating a variety of diseases and disorders, including inflammation and cardiovascular disease.
- Adhesion of leukocytes to the endothelium represents a fundamental, early event in a wide variety of inflammatory conditions, autoimmune disorders and bacterial and viral infections. Leukocyte recruitment to endothelium is mediated in part by the inducible expression of adhesion molecules on the surface of endothelial cells that interact with counterreceptors on immune cells. Endothelial cells determine which types of leukocytes are recruited by selectively expressing specific adhesion molecules, such as vascular cell adhesion molecule-1 (VCAM-1), intercellular adhesion molecule-1 (ICAM-1), and E-selectin. VCAM-1 binds to the integrin VLA-4 expressed on lymphocytes, monocytes, macrophages, eosinophils, and basophils but not neutrophils. This interaction facilitates the firm adhesion of these leukocytes to the endothelium. VCAM-1 is an inducible gene that is not expressed, or expressed at very low levels, in normal tissues. VCAM-1 is upregulated in a number of inflammatory diseases, including arthritis (including rheumatoid arthritis), asthma, dermatitis, psoriasis, cystic fibrosis, post transplantation late and chronic solid organ rejection, multiple sclerosis, systemic lupus erythematosis, inflammatory bowel diseases, autoimmnune diabetes, diabetic retinopathy, rhinitis, ischemia-reperfusion injury, post-angioplasty restenosis, chronic obstructive pulmonary disease (COPD), glomerulonephritis, Graves disease, gastrointestinal allergies, conjunctivitis, atherosclerosis, coronary artery disease, angina and small artery disease.
- Coronary heart disease (CHD), primarily as a result of atherosclerosis, remains the leading cause of death in industrialized countries. Atherosclerosis is a disease characterized by vascular inflammation, deposition of lipids in the arterial vessel wall and smooth muscle cell proliferation resulting in a narrowing of the vessel passages. In advanced stages of the disease atherosclerotic lesions can become unstable resulting in plaque rupture, thrombosis, myocardial infarction and ischemic heart disease. It is now well accepted that the initiating events in atherosclerosis are local injury to the arterial endothelium that results in the induction of VCAM-1 and recruitment of mononuclear leukocytes that express the integrin counterreceptor, VLA-4, (O'Brien, et al., J. Clin. Invest., 92: 945-951, 1993). Subsequent conversion of leukocytes to foamy macrophages results in the synthesis of a wide variety of inflammatory cytokines, growth factors, and chemoattractants that help propagate formation of the mature atheromatous plaque by further inducing endothelial activation, leukocyte recruitment, smooth muscle cell proliferation, and extracellular matrix deposition. Pharmacological inhibition of VCAM-1 expression has been shown to inhibit atherosclerosis in several animal models (Sundell et al., Circulation, 100: 42, 1999). A monoclonal antibody against VCAM-1 has also been shown to inhibit neointimal formation in a mouse model of arterial wall injury (Oguchi, S., et al., Arterioscler. Thromb. Vasc. Biol., 20: 1729-1736, 2000).
- Asthma, which is increasing in prevalence and morbidity world-wide, is a chronic inflammatory disease characterized by lung eosinophilia and bronchial hyperreactivity. The interaction between VCAM-1 on lung endothelial cells and VLA-4, which is the integrin counterreceptor expressed on eosinophils, is thought to be important for selective eosinophil recruitment. Eosinophils have been considered an important effector cell in the pathogenesis of asthma and other allergic diseases. Activated eosinophils release proteins such as major basic protein (MBP) that have been demonstrated to induce bronchial hyperreactivity, one of the defining criteria of asthma (Bousquot, et al., N. Engl. J. Med., 323: 1033-1039, 1990). It has been demonstrated that VCAM-1 is markedly upregulated on human bronchial vascular endothelium of subjects with asthma who have air flow limitation, when compared with subjects without asthma (Pilewski, et al., Am. J. Respir. Cell Mol. Biol., 12, 1-3, 1995; Ohkawara, Y., et al., Am. J. Respir. Cell Mol. Biol., 12, 4-12, 1995; Gosset, P., et al., Int. Arch. Allergy Immunol. 106: 69-77, 1995; Hacken, N. H., et al., Clin. Exp. Allergy, 28 (12): 1518-1525, 1998). An elevation in serum soluble VCAM-1 levels has also been demonstrated in patients undergoing a bronchial asthma attack compared with levels under stable conditions (Montefort, S., Koizumi, A., Clin. Exp. Immunol., 101: 468-73, 1995). Several animal studies further demonstrate a spatial and temporal association between VCAM-1 and asthma. In a mouse model of allergic asthma, VCAM-1 expression was shown to be induced by allergen challenge, and administration of an anti-VCAM-1 antibody was effective in inhibiting eosinophil infiltration that occurred in this model (Metzger, W. J., et al., J. Allergy Clin. Immunol., 93: 183, 1994). Further evidence for the importance of VCAM-1 in allergic asthma comes from work in IL-12 knockout mice. IL-12 knockout mice had fewer eosinophils and VCAM-1 expression than wildtype mice; however, administration of recombinant IL-12 at the time of ova sensitization and challenge restored lung VCAM-1 expression and eosinophilia (Wang, S., et al., J. Immunol., 166:2741-2749, 2001). There are several examples where blocking the integrin receptors for VCAM-1 have had positive effects on animal models of asthma (Rabb et al., Am. J. Respir. Care Med. 149: 1186-1191, 1994; Abraham, W, et al., Am. J. Respir. Crit. Care Med. 156: 696-703. 1997) further demonstrating the importance of VCAM-1/VLA-4 interactions in allergic inflammation. Eosinophils are also important effector cells in allergic rhinitis. VCAM-1 has been demonstrated to be upregulated 24 hrs after nasal allergen provocation in patients with seasonal allergic rhinitis but not in normal subjects (Braunstahl, G. J., et al., J. Allergy Clin. Immunol., 107: 469-476, 2001).
- Rheumatoid arthritis (RA) is a clinical syndrome of unknown cause characterized by symmetric, polyarticular inflammation of synovial-lined joints. The role of adhesion molecules in the pathogenesis of RA has also been well documented, and VCAM-1 expression on synovial fibroblasts is a clinical hallmark of RA (Li, P., et al., J. Immunol. 164: 5990-7, 2000). VLA-4/VCAM-1 interactions may be the predominant mechanism for recruitment of leukocytes to the synovium (Dinther-Janssen, et al., J. Immunol. 147: 4207-4210, 1991; Issekeutz and Issekeutz, Clin. Immunol. Immunopathol. 61:436-447, 1991; Morales-Ducret et al., J. Immunol. 149:1424-1431, 1992; Postigo et al., J. Clin. Invest. 89:1445-1452, 1992; Matsuyama, T., et al, Hum. Cell, 9: 187-192, 1996). In support of this, increased VCAM-1 expression has been found in RA synovial tissue compared with osteoarthritis and control tissue (Wilkinson et al., Lab. Invest. 69:82-88, 1993; Furuzawa-Carballeda, J., et al., Scand. J. Immunol. 50: 215-222; 1999). Soluble VCAM-1 is higher in RA patients than in control subjects (Kolopp-Sarda, M. N., et al., Clin. Exp. Rheumatol. 19: 165-70, 2001). Soluble VCAM-1 has been shown to be chemotactic for T cells (Kitani, A., et al., J. Immun. 161: 4931-8, 1998), and in addition to being a possible diagnostic marker for RA, may contribute to its pathogenesis by inducing migration and recruitment of T cells. VCAM-1 expressed on fibroblast-like synoviocytes has also been implicated in enhanced survival of activated synovial fluid B cells (Marinova, Mutafcheia, L., Arthritis Rheum. 43: 638-644, 2000) that may further contribute to RA pathogenesis.
- Chronic inflammation and accompanying vascular complications and organ damage characterize systemic lupus erythematosis (SLE). Recent studies suggest that VCAM-1 plays a role in SLE. Expression of VCAM-1 is increased on dermal vessel endothelial cells in patients with active systematic lupus erythematosus (Jones, S. M., British J Dermatol. 135: 678-686, 1996) and correlates with increased disease severity (Belmont et al., Arthritis Rheum. 37:376-383, 1994). SLE muscle samples with perivascular infiltrate have greater endothelial cell expression of VCAM-1 compared with SLE patients without a perivascular infiltrate or with control samples (Pallis et al., Ann. Rheum. Dis. 52:667-671, 1993). Increased expression of VCAM-1 has also been demonstrated in kidneys of lupus-prone MRL/lpr mice compared to nonautoimmune strains and its expression increased with disease severity (McHale, J. F., et al., J. Immunol. 163: 3993-4000, 1999). VCAM-1 expression on mesangial cells in vitro can be stimulated by IL-1, TNF-α, and INFγ exposure as well as by anti-endothelial cell IgG fraction and anti-DNA autoantibodies from SLE patients (Wuthrich, Kidney Int. 42: 903-914, 1992; Papa, N. D., et al., Lupus, 8: 423-429, 1999; Lai, K. N., et al., Clin Immunol Immunopathol, 81: 229-238, 1996). Furthermore, soluble VCAM-1 is higher in SLE patients than in normal subjects (Mrowka, C., et al., Clin. Nephrol. 43: 288-296, 1995; Baraczka, K., et al., Acta. Neurol. Scand 99: 95-99, 1999; Kaplanski; G.; et al., Arthritis Rheumol. 43: 55-64, 2000; Ikeda, Y., Lupus, 7: 347-354, 1998) and correlates with disease activity (Scudla, V., Vnitr. Lek, 43: 307-311, 1997).
- Increased VCAM-1 expression has also been demonstrated in solid organ transplant rejection. Acute transplant rejection occurs when the transplant recipient recognizes the grafted organ as “non-self” and mounts an immune response characterized by massive infiltration of immune cells, edema, and hemorrage that result in the death of the transplanted organ. Acute rejection occurs in a matter of hours or days and has been correlated with increased levels of VCAM-1 in tissues and in plasma (Tanio et al., Circulation, 89:1760-1768, 1994; Cosimi et al., J. Immunol. 144: 4604-4612, 1990; Pelletier, R., et al., Transplantation, 55: 315, 1992). A monoclonal antibody to VCAM-1 has been shown to inhibit cardiac allograft rejection in mice (Pelletier, R., J. Immunol., 149: 2473-2481, 1992; Pelletier, R., et al., Transplantation Proceedings, 25: 839-841, 1993; Orosz, C. G., et al., J. Heart and Lung Transplantation, 16: 889-904, 1997) and when given for 20 days can cause complete inhibition of rejection and long-term graft acceptance (Orosz C. G., et al., Transplantation, 56: 453-460, 1993). Chronic graft rejection also known as allograft vasculopathy is distinct from acute transplant rejection and is a leading cause of late graft loss after renal and heart transplantation. Histologically it is characterized by concentric neointimal growth within vessels that is largely due to smooth muscle migration and proliferation. It is thought to be the result of endothelial damage brought about by several factors including: ischemia-reperfusion injury, immune complexes, hypertension, hyperlipidemia and viruses. All of these factors have been associated with induction of VCAM-1 in endothelial cells. There is also a strong correlation of soluble and tissue VCAM-1 levels with chronic rejection (Boratynska, M., Pol. Arch. Med. Wewn, 100: 410-410, 1998; Zembala, M., et al., Ann. Transplant. 2: 16-9, 1998; Solez K., et al., Kidney International., 51: 1476-1480, 1997; Koskinen P. K., et al., Circulation, 95: 191-6, 1997).
- Multiple sclerosis is a common demyelinating disorder of the central nervous system, causing patches of sclerosis (plaques) in the brain and spinal cord. It occurs in young adults and has protean clinical manifestations. It is well documented that VCAM-1 is expressed on brain microvascular endothelial cells in active lesions of multiple sclerosis (Lee S. J., et al., J. Neuroimmunol, 98: 77-88, 1998). Experimental therapy of experimental autoimmune encephalomyelitis, which is an animal model for multiple sclerosis, using antibodies against several adhesion molecules, including VCAM-1, clearly shows that adhesion molecules are critical for the pathogenesis of the disease (Benveniste et al., J. Neuroimmunol. 98:77-88, 1999). A time and dose dependent expression of VCAM-1 and release of soluble VCAM-1 were detected in cultures of human cerebral endothelial cells induced by TNFα, but not in peripheral blood mononuclear cells (Kallmann et al., Brain, 123:687-697, 2000). Clinical data also show that adhesion molecules in blood and cerebrospinal fluid are up-regulated throughout the clinical spectrum of multiple sclerosis (Baraczka, K., et al., Acta. Neurol. Scand. 99: 95-99, 1999; Reickmann, P., et al., Mult. Scler., 4: 178-182, 1998; Frigerio, S., et al., J. Neuroimmunol, 87: 88-93, 1998) supporting the notion that therapies which interfere with cell adhesion molecules such as VCAM-1 may be beneficial in modifying this disease (Elovaara et al., Arch. Neurol. 57:546-551, 2000).
- Diabetes mellitus is a metabolic disease in which carbohydrate utilization is reduced and that of lipid and protein is enhanced. Evidence has accumulated that increased levels of adhesion molecules may play a functional pathophysiological role in diabetes (Wagner and Jilma, Hormone and Metabolic Research, 29: 627-630, 1997; Kado, S., Diabetes Res. Clin. Pract., 46: 143-8, 1999). It is caused by an absolute or relative deficiency of insulin and is characterized by chronic hyperglycemia, glycosuria, water and electrolyte loss, ketoacidosis, and coma. Elevated circulating adhesion molecules including VCAM-1 have been detected in patients with diabetes and in experimental models of diabetes in animals (Lorini et al., Hormone Research, 48: 153, 1997; Otsuki et al., Diabetologia, 40: A440, 1997; Hart et al., FASEB J. 11:A340, 1997; Albertini et al., Diabetologia, 39: A240, 1996; Wagner et al., Diabetologia, 39: A205, 1996; Enghofer et al., Diabetologia, 39: A97, 1996; Koga M., Diabet. Med., 15: 661-667, 1998). In addition, complications of diabetes often include peripheral vasculopathies such as diabetic retinopathy and diabetic nephropathy. It is believed that adhesion of leukocytes to the peripheral vasculature plays a central role in the vasculopathies often associated with diabetes.
- Crohn's disease, also known as regional enteritis, is a subacute chronic inflammatory condition of unknown cause, involving the internal ileum and less frequently other parts of the gastrointestinal tract. It is characterized by patchy deep ulcers that may cause fistulas, and narrowing and thickening of the bowel by fibrosis and lymphocytic infiltration. Ulcerative colitis is a chronic disease of unknown cause characterized by ulceration of the colon and rectum, with rectal bleeding, mucosal crypt abscesses, inflammatory pseudopolyps, abdominal pain, and diarrhea. It has been reported that serum VCAM-1 reflects the grade of intestinal inflammation in patients with Crohn's disease or ulcerative colitis (Jones, et al., Gut, 36: 724-30, 1995; Goggins et al., Gastroenterology, 108: A825, 1995; Goeke and Manns, Gastroenterology, 106: A689, 1994; Goeke et al., J. Gasterokenterol. 32:480-486, 1997; Loftus et al., Gastroenterology, 108: A684, 1995; Tahami et al., Gastroenterology, 118: A344, 2000). Antibodies to VCAM-1 have been shown to ameliorate experimentally-induced colitis in mice (Soriano, A., Lab. Invest. 80: 1541-1551, 2000).
- Psoriasis is a chronic skin disease characterized by erythematous scaling plaques as a result of keratinocyte hyperplasia, influx of immune cells and endothelial activation (Nickoloff, B. J., et al., J. Invest. Dermatol., 127: 871-884, 1991). VCAM-1 is upregulated in psoriatic skin as compared to normal skin (Groves, R. W., J. Am. Acad. Dermatol., 29: 67-72, 1993; Uyemura, K., et al., J. Invest. Dermatol. 101: 701-705, 1993) and levels of circulating VCAM-1 correlate with disease activity (Schopf, R. E., Br. J. Dermatol., 128: 34-7, 1993).
- U.S. Pat. Nos. 5,750,351; 5,807,884; 5,811,449; 5,846,959; 5,773,231, and 5,773,209 to Medford, et al., as well as the corresponding WO 95/30415 to Emory University indicate that polyunsaturated fatty acids (“PUFAs”) and their hydroperoxides (“ox-PUFAs”), which are important components of oxidatively modified low density lipoprotein (LDL), induce the expression of VCAM-1, but not intracellular adhesion molecule-1 (ICAM-1) or E-selectin in human aortic endothelial cells, through a mechanism that is not mediated by cytokines or other noncytokine signals. This is a fundamental discovery of an important and previously unknown biological pathway in VCAM-1 mediated immune responses. As non-limiting examples, linoleic acid, linolenic acid, arachidonic acid, linoleyl hydroperoxide (13-HPODE) and arachidonic hydroperoxide (15-HPETE) induce cell-surface gene expression of VCAM-1 but not ICAM-1 or E-selectin. Saturated fatty acids (such as stearic acid) and monounsaturated fatty acids (such as oleic acid) do not induce the expression of VCAM-1, ICAM-1 or E-selectin.

- Synthesis of the Active Compounds
- The compounds of the present invention can be readily prepared by those skilled in the art of organic synthesis using commonly known methods, many of which are described by J, March, in Advanced Organic Chemistry, 4th Edition (Wiley Interscience, New York, 1992) and D. N. Dnar in The Chemistry of Chalcones and Related Compounds (Wiley-Interscience, New York, 1981), incorporated herein by reference.
- Compounds of the present invention are prepared either by reacting a heteroaryl- or heterocyclic-substituted aryl or heteroaryl ketone with a suitably substituted aryl aldehyde or by reacting a suitably substituted aryl ketone with a heteroaryl- or heterocyclic-substituted aryl or heteroaryl aldehyde. This reaction, which is a condensation reaction, is suitably carried out under base- or acid-catalyzed conditions. The reaction may be suitably carried out in water or protic organic solvents such as lower alcohols (e.g. methanol, ethanol, tert-butanol), lower carboxylic acid (e.g. formic acid, glacial acetic acid, propionic acid), or in aprotic organic solvents such as ethers (e.g. tetrahydrofuran, dioxane, diethyl ether), liquid amides (e.g. dimethylformamide, hexamethylphosphordiamide), dimethylsulfoxide, or hydrocarbons (e.g. toluene, benzene), or mixtures of such solvents. When carrying out the reaction under basic conditions, the base may be selected from sodium, lithium, potassium, barium, calcium, magnesium, aluminum, ammonium, or quarternary ammonium hydroxides, lower alkoxides (e.g. methoxides, ethoxides, tert-butoxides), carbonates, borates; oxides, hydrides, or amides of lower secondary amines (e.g. diisopropyl amides, methylphenyl amides). Primary aromatic amines such as aniline, free secondary amines such as dimethyl amine, diethyl amine, piperidine, or pyrrolidine, tertiary amines such as pyridine, as well as basic ion exchange resins may also be used. Alternatively, a phase-transfer catalyst such as cetyl trimethyl ammonium chloride can also be used to facilitate the reaction, particularly when water is the solvent.
- Alternatively, the aldol condensation reaction can also be carried out in an aprotic solvent such as tetrahydrofuran (THF) with an organic base. The preferred solvent is THF and the preferred base is lithium diisopropylamide (LDA). In this manner an aldol reaction may take place first and the subsequent dehydration reaction may take place during an aqueous workup.
- Acid catalysts may be selected from hydrogen chloride, hydrogen bromide, hydrogen iodide, sulfuric acid, sulfonic acids (such as paratoluenesulfonic or methansulfonic acid), lower carboxylic acid (such as formic, acetic, or propionic acid), lower halogenated carboxylic acid (such as trifluoroacetic acid), Lewis acids (such as BF3, POCl3, PCl5, FeCl3), or acid ion exchange resins.
- The reaction may be carried out at temperatures in the range of −80° C. to +150° C., preferrably in the range of 0° C. to +100° C., and more preferably at room temperature. The time of reaction may be from 30 minutes to approximately 24 hours.
- Compounds of the invention may be isolated as either mixtures of cis (Z) and trans (E) geometric isomers or either pure trans (E) isomers. If desired, either the mixtures or the pure trans isomers may be isomerized to the corresponding predominantly cis (Z) iomers using methods well known in the literature.
- In the above reactions, it may be preferred or necessary to protect various sensitive or reactive groups present in the starting materials so as to prevent said groups from interfering with the reactions. Such protection may be carried out in a well-known manner as taught by Theodora W. Green and Peter G. M. Wuts, in Protective Groups in Organic Chemistry Third Edition (Wiley, 1999) or using methods from references cited therein or of the like. The protecting group may be removed after the reaction in a manner known per se.

- An alternative procedure: 5-bromo-2,4-dimethoxybenzaldehyde (20 g), benzo[b]thiophene-2-boronic acid (16 g) and THF (200 mL) were sequentially charged into a clean reaction vessel fitted with a reflux condenser, mechanical stirrer and nitrogen inlet adapter. Nitrogen was bubbled into the resulting solution for 20 min followed by the sequential addition of KF (10 g), and Pd(1Bu3P)2 (0.417 g). The solution was immediately heated to 60° C. and aged for 1.5 h. (Note: The HPLC assay at this point routinely indicated complete consumption of 5-bromo-2,4-dimethoxybenzaldehyde, <0.5 area % of benzo[b]thiophene-2-boronic acid along with 0.5 area % of an unknown (0.55 RRT). These impurities are removed during crystallization.) Upon completion, as determined by HPLC, the reaction was diluted with H2O (200 mL) and transferred to a separatory funnel containing EtOAc (200 mL) and H2O (200 mL). The layers were cut and the aqueous layer was extracted with EtOAc (100 mL). The combined organic cuts were filtered through a pre-washed pad of solka floe (5 g). The pad of solka floe and spent catalyst were washed with fresh EtOAc (200 mL) and this wash combined with the batch.

- To a solution of 2,4-dimethoxy-benzaldehyde (20.0 g, 120.4 mmol) in methanol (550 mL) was added a solution of iodine monochloride (23.52 g, 144.9 mmol) in methanol (60 mL) dropwise over 20 min. The solution was allowed to stir at ambient temperature for 3 hours and then poured into a solution of hydrochloric acid (0.5 M, 600 mL). The resulting precipitate was collected by filtration, washed with water, and dried in vacuo. The crude product was further recrystallized from a mixture of tetrahydrofuran and heptane (1:1, v/v) to give the tiltle compound as a white solid (30.62 g, 87.5%), m.p. 170-172° C. 1H NMR (CDCl3) δ 10.19 (s, 1H), 8.22 (s, 1H), 6.39 (s, 1H), 3.97 (s, 3H), 3.95 (s, 3H).

- Ex-123A: Potassium fluoride (0.42 g, 7.2 mmol), 5-iodo-2,4-dimethoxy-benzaldehyde (Ex-123, 11.0 g, 3.42 mmol), 2-benzo[b]thiophene boronic acid (0.67 g, 3.77 mmol), degased tetrahydrofuran (10 mL), tris(dibenzylideneacetone)dipalladium (19 mg, 0.02 mmol), and tri-tert-butylphosphine (100 mg, 0.05 mmol) were sequentially charged into a flask equipped with a condenser and nitrogen inlet adapter. The reaction mixture was heated at 60° C. for one hour under nitrogen. HPLC analysis indicated of 100% conversion of 5-iodo-2,4-dimethoxy- benzaldehyde (Ex-123) to the title compound prepared through another route (Ex-3A).

- It is appreciated that compounds of the present invention having a chiral center may exist in and be isolated in optically active and racemic forms. Some compounds may exhibit polymorphism. It is to be understood that the present invention encompasses any racemic, optically-active, diastereomeric, polymorphic, or stereoisomeric form, or mixtures thereof, of a compound of the invention, which possess the useful properties described herein, it being well known in the art how to prepare optically active forms (for example, by resolution of the racemic form by recrystallization techniques, by synthesis from optically-active starting materials, by chiral synthesis, or by chromatographic separation using a chiral stationary phase).
- Examples of methods to obtain optically active materials are known in the art, and include at least the following.
-
- i) physical separation of crystals—a technique whereby macroscopic crystals of the individual enantiomers are manually separated. This technique can be used if crystals of the separate enantiomers exist, i.e., the material is a conglomerate, and the crystals are visually distinct;
- ii) simultaneous crystallization—a technique whereby the individual enantiomers are separately crystallized from a solution of the racemate, possible only if the latter is a conglomerate in the solid state;
- iii) enzymatic resolutions—a technique whereby partial or complete separation of a racemate by virtue of differing rates of reaction for the enantiomers with an enzyme;
- iv) enzymatic asymmetric synthesis—a synthetic technique whereby at least one step of the synthesis uses an enzymatic reaction to obtain an enantiomerically pure or enriched synthetic precursor of the desired enantiomer;
- v) chemical asymmetric synthesis—a synthetic technique whereby the desired enantiomer is synthesized from an achiral precursor under conditions that produce asymmetry (i.e., chirality) in the product, which may be achieved using chiral catalysts or chiral auxiliaries;
- vi) diastereomer separations—a technique whereby a racemic compound is reacted with an enantiomerically pure reagent (the chiral auxiliary) that converts the individual enantiomers to diastereomers. The resulting diastereomers are then separated by chromatography or crystallization by virtue of their now more distinct structural differences and the chiral auxiliary later removed to obtain the desired enantiomer;
- vii) first- and second-order asymmetric transformations—a technique whereby diastereomers from the racemate equilibrate to yield a preponderance in solution of the diastereomer from the desired enantiomer or where preferential crystallization of the diastereomer from the desired enantiomer perturbs the equilibrium such that eventually in principle all the material is converted to the crystalline diastereomer from the desired enantiomer. The desired enantiomer is then released from the diastereomer;
- viii) kinetic resolutions—this technique refers to the achievement of partial or complete resolution of a racemate (or of a further resolution of a partially resolved compound) by virtue of unequal reaction rates of the enantiomers with a chiral, non-racemic reagent or catalyst under kinetic conditions;
- ix) enantiospecific synthesis from non-racemic precursors—a synthetic technique whereby the desired enantiomer is obtained from non-chiral starting materials and where the stereochemical integrity is not or is only minimally compromised over the course of the synthesis;
- x) chiral liquid chromatography—a technique whereby the enantiomers of a racemate are separated in a liquid mobile phase by virtue of their differing interactions with a stationary phase. The stationary phase can be made of chiral material or the mobile phase can contain an additional chiral material to provoke the differing interactions;
- xi) chiral gas chromatopraphy—a technique whereby the racemate is volatilized and enantiomers are separated by virtue of their differing interactions in the gaseous mobile phase with a column containing a fixed non-racemic chiral adsorbent phase;
- xii) extraction with chiral solvents—a technique whereby the enantiomers are separated by virtue of preferential dissolution of one enantiomer into a particular chiral solvent;
- xiii) transport across chiral membranes—a technique whereby a racemate is placed in contact with a thin membrane barrier. The barrier typically separates two miscible fluids, one containing the racemate, and a driving force such as concentration or pressure differential causes preferential transport across the membrane barrier. Separation occurs as a result of the non-racemic chiral nature of the membrane which allows only one enantiomer of the racemate to pass through.
Pharmaceutically Acceptable Salt Formulations
- In cases where compounds are sufficiently basic or acidic to form stable nontoxic acid or base salts, administration of the compound as a pharmaceutically acceptable salt may be appropriate. The term “pharmaceutically acceptable salts” or “complexes” refers to salts or complexes that retain the desired biological activity of the compounds of the present invention and exhibit minimal undesired toxicological effects.
- Examples of pharmaceutically acceptable salts are organic acid addition salts formed with acids, which form a physiological acceptable anion, for example, tosylate, methanesulfonate, acetate, citrate, malonate, tartarate, succinate, benzoate, ascorbate, α-ketoglutarate and α-glycerophosphate. Suitable inorganic salts may also be formed, including, sulfate, nitrate, bicarbonate and carbonate salts. Alternatively, the pharmaceutically acceptable salts may be made with sufficiently basic compounds such as an amine with a suitable acid affording a physiologically acceptable anion. Alkali metal (for example, sodium, potassium or lithium) or alkaline earth metal (for example calcium) salts of carboxylic acids can also be made.
- Nonlimiting examples of such salts are (a) acid addition salts formed with inorganic acids (for example, hydrochloric acid, hydrobromic acid, sulfuric acid, phosphoric acid, nitric acid, and the like), and salts formed with organic acids such as acetic acid, oxalic acid, tartaric acid, succinic acid, malic acid, ascorbic acid, benzoic acid, tannic acid, pamoic acid, alginic acid, polyglutamic acid, naphthalenesulfonic acid, naphthalenedisulfonic acid, and polygalcturonic acid; (b) base addition salts formed with metal cations such as zinc, calcium, bismuth, barium, magnesium, aluminum, copper, cobalt, nickel, cadmium, sodium, potassium, and the like, or with a cation formed from ammonia, N,N-dibenzylethylenediamine, D-glucosamine, tetraethylammonium, or ethylenediamine; or (c) combinations of (a) and (b); e.g., a zinc tannate salt or the like. Also included in this definition are pharmaceutically acceptable quaternary salts known by those skilled in the art, which specifically include the quaternary ammonium salt of the formula —NR+A−, wherein R is as defined above and A is a counterion, including chloride, bromide, iodide, —O-alkyl, toluenesulfonate, methylsulfonate, sulfonate, phosphate, or carboxylate (such as benzoate, succinate, acetate, glycolate, maleate, malate, citrate, tartrate, ascorbate, benzoate, cinnamoate, mandeloate, benzyloate, and diphenylacetate).

- A particular class of salts can be classified as organic amine salts. The organic amines used to form these salts can be primary amines, secondary amines or tertiary amines, and the substituents on the amine can be straight, branched or cyclic groups, including ringed structures formed by attachment of two or more of the amine substituents. Of particular interest are organic amines that are substituted by one or more, hydroxyalkyl groups, including alditol or carbohydrate moieties. These hydroxy substituted organic amines can be cyclic or acyclic, both classes of which can be primary amines, secondary amines or tertiary amines. A common class of cyclic hydroxy substituted amines are the amino sugars.
- Carbohydrate moieties that can comprise one or more substituents in the amine salt include those made from substituted and unsubstituted monosaccharides, disaccharides, oligosaccharides, and polysaccharides. The saccharide can be an aldose or ketose, and may comprise 3, 4, 5, 6, or 7 carbons. In one embodiment the carbohydrates are monosaccharides. In another embodiment the carbohydrates are pyranose and furanose sugars. Non limiting examples of pyranose and furanose moieties that can be part of the organic amine salt include threose, ribulose, ketose, gentiobiose, aldose, aldotetrose, aldopentose, aldohexose, ketohexose, ketotetrose, ketopentose, erythrose, threose, ribose, deoxyribose, arabinose, xylose, lyxose, allose, altrose, glucose, mannose, gulose, idose, glactose, talose, erythrulose, ribulose, xylulose, psicose, fructose, sorbose, tagatose, dextrose, maltose, lactose, sucrose, cellulose, aldose, amylose, palatinose, trehalose, turanose, cellobiose, amylopectin, glucosamine, mannosamine, fucose, phamnose, glucuronate, gluconate, glucono-lactone, muramic acid, abequose, rhamnose, gluconic acid, glucuronic acid, and galactosamine. The carbohydrate moiety can optionally be deoxygenated at any corresponding C-position, and/or substituted with one or more moieties such as hydrogen, halo, haloalkyl, carboxyl, acyl, acyloxy, amino, amido, carboxyl-derivatives, alkylamino, dialkylamino, arylamino, alkoxy, aryloxy, nitro, cyano, sulfonic acid, thiol, imine, sulfonyl, sulfanyl, sulfinyl, sulfamonyl, ester, carboxylic acid, amide, phosphonyl, phosphinyl, phosphoryl, thioester, thioether, oxime, hydrazine, carbamate, phosphonic acid, phosphonate, or any other viable functional group that does not inhibit the pharmacological activity of this compound. Exemplary substituents include amine and halo, particularly fluorine. The substituent or carbohydrate can be either unprotected, or protected as necessary, as known to those skilled in the art, for example, as taught in Greene, et al., Protective Groups in Organic Synthesis, John Wiley and Sons, Second Edition, 1991, hereby incorporated by reference. In one embodiment the monosaccharide is a furanose such as (L or D)-ribose.
- Of particular interest among the acyclic organic amines are a class represented by the formula
wherein Y and Z are independently hydrogen or lower alkyl or, may be taken together to form a ring, R is hydrogen, alkyl or hydroxyloweralkyl, and n is 1, 2, 3, 4, or 5. Among these hydroxylamines are a particular class characterized when n is 4. A representative of this group is meglumine, represented when Y is hydrogen, Z is methyl and R is methoxy. Meglumine is also known in the art as N-methylglucamine, N-MG, and 1-deoxy-1-(methylamino)-D-glucitol. - The invention also includes pharmaceutically acceptable prodrugs of the compounds. Pharmaceutically acceptable prodrugs refer to a compound that is metabolized, for example hydrolyzed or oxidized, in the host to form the compound of the present invention. Typical examples of prodrugs include compounds that have biologically labile protecting groups on a functional moiety of the active compound. Prodrugs include compounds that can be oxidized, reduced, aminated, deaminated, hydroxylated, dehydroxylated, hydrolyzed, dehydrolyzed, alkylated, dealkylated, acylated, deacylated, phosphorylated, dephosphorylated to produce the active compound.

They are also indicated for the prevention or treatment of graft-versus-host disease, which sometimes occurs following bone marrow transplantation.
- In an alternative embodiment, the compounds described herein are useful in both the primary and adjunctive medical treatment of cardiovascular disease. The compounds are used in primary treatment of, for example, coronary disease states including atherosclerosis, post- angioplasty restenosis, coronary artery diseases and angina. The compounds can be administered to treat small vessel disease that is not treatable by surgery or angioplasty, or other vessel disease in which surgery is not an option. The compounds can also be used to stabilize patients prior to revascularization therapy.
- In another aspect the invention provides pharmaceutical compositions for the treatment of diseases or disorders mediated by VCAM-1 wherein such compositions comprise a VCAM-1 inhibiting amount of a chalcone derivatives of the invention or a pharmaceutically acceptable salt thereof and/or a pharmaceutically acceptable carrier.

- The compounds of the present invention can be used to treat any disorder that is mediated by VCAM-1. VCAM-1 is upregulated in a wide variety of disease states, including but not limited to arthritis, asthma, dermatitis, psoriasis, cystic fibrosis, post transplantation late and chronic solid organ rejection, multiple sclerosis, systemic lupus erythematosis, inflammatory bowel diseases, autoimmune diabetes, diabetic retinopathy, diabetic nephropathy, diabetic vasculopathy, rhinitis, ischemia-reperfusion injury, post-angioplasty restenosis, chronic obstructive pulmonary disease (COPD), glomerulonephritis, Graves disease, gastrointestinal allergies, atherosclerosis, coronary artery disease, angina, small artery disease, and conjunctivitis.
- Nonlimiting examples of arthritis include rheumatoid (such as soft-tissue rheumatism and non-articular rheumatism, fibromyalgia, fibrositis, muscular rheumatism, myofascil pain, humeral epicondylitis, frozen shoulder, Tietze's syndrome, fascitis, tendinitis, tenosynovitis, bursitis), juvenile chronic, spondyloarthropaties (ankylosing spondylitis), osteoarthritis, hyperuricemia and arthritis associated with acute gout, chronic gout and systemic lupus erythematosus.
- Human endothelial disorders mediated by VCAM-1 include psoriasis, eczematous dermatitis, Kaposi's sarcoma, as well as proliferative disorders of smooth muscle cells.
- In yet another embodiment, the compounds disclosed herein can be selected to treat anti-inflammatory conditions that are mediated by mononuclear leucocytes.
- In one embodiment, the compounds of the present invention are selected for the prevention or treatment of tissue or organ transplant rejection. Treatment and prevention of organ or tissue transplant rejection includes, but are not limited to treatment of recipients of heart, lung, combined heart-lung, liver, kidney, pancreatic, skin, spleen, small bowel, or corneal transplants. The compounds can also be used in the prevention or treatment of graft-versus- host disease, such as sometimes occurs following bone marrow transplantation.
- In an alternative embodiment, the compounds described herein are useful in both the primary and adjunctive medical treatment of cardiovascular disease. The compounds are used in primary treatment of, for example, coronary disease states including atherosclerosis, post- angioplasty restenosis, coronary artery diseases and angina. The compounds can be administered to treat small vessel disease that is not treatable by surgery or angioplasty, or other vessel disease in which surgery is not an option. The compounds can also be used to stabilize patients prior to revascularization therapy.
- In addition to inhibiting the expression of VCAM-1, some of the compounds of the invenion have the additional properties of inhibiting monocyte chemoattractant protein-i (MCP-1) and/or smooth muscle proliferation. MCP-1 is a chemoattractant protein produced by endothelial cells, smooth muscle cells as well as macrophages. MCP-1 promotes integrin activation on endothelial cells thereby facilitating adhesion of leukocytes to VCAM-1, and MCP-1 is a chemoattractant for monocytes. MCP-1 has been shown to play a role in leukocyte recruitment in a number of chronic inflammatory diseases including atherosclerosis, rheumatoid arthritis, and asthma. Its expression is upregulated in these diseases and as such inhibition of MCP-1 expression represents a desirable property of anti-inflammatory therapeutics. Furthermore, smooth muscle cell hyperplasia and resulting tissue remodeling and decreased organ function is yet another characteristic of many chronic inflammatory diseases including atherosclerosis, chronic transplant rejection and asthma. Inhibition of the hyperproliferation of smooth muscle cells is another desirable property for therapeutic compounds.
- Combination and Alternation Therapy
- Any of the compounds disclosed herein can be administered in combination or alternation with a second biologically active agent to increase its effectiveness against the target disorder.
- In combination therapy, effective dosages of two or more agents are administered together, whereas during alternation therapy an effective dosage of each agent is administered serially. The dosages will depend on absorption, inactivation and excretion rates of the drug as well as other factors known to those of skill in the art. It is to be noted that dosage values will also vary with the severity of the condition to be alleviated. It is to be further understood that for any particular subject, specific dosage regimens and schedules should be adjusted over time according to the individual need and the professional judgment of the person administering or supervising the administration of the compositions.
- The efficacy of a drug can be prolonged, augmented, or restored by administering the compound in combination or alternation with a second, and perhaps third, agent that induces a different biological pathway from that caused by the principle drug. Alternatively, the pharmacokinetics, biodistribution or other parameter of the drug can be altered by such combination or alternation therapy. In general, combination therapy is typically preferred over alternation therapy because it induces multiple simultaneous stresses on the condition.
- Any method of alternation can be used that provides treatment to the patient. Nonlimiting examples of alternation patterns include 1-6 weeks of administration of an effective amount of one agent followed by 1-6 weeks of administration of an effective amount of a second agent. The alternation schedule can include periods of no treatment. Combination therapy generally includes the simultaneous administration of an effective ratio of dosages of two or more active agents.
- Illustrative examples of specific agents that can be used in combination or alternation with the compounds of the present invention are described below in regard to asthma and arthritis. The agents set out below or others can alternatively be used to treat a host suffering from any of the other disorders listed above or that are mediated by VCAM-1 or MCP-1.

- In another aspect, the second biologically active agent is a statin. Statins lower cholesterol by inhibiting of 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase, a key enzyme in the cholesterol biosynthetic pathway. The statins decrease liver cholesterol biosynthesis, which increases the production of LDL receptors thereby decreasing plasma total and LDL cholesterol (Grundy, S. M. New Engl. J. Med. 319, 24 (1988); Endo, A. J. Lipid Res. 33, 1569 (1992)). Depending on the agent and the dose used, statins may decrease plasma triglyceride levels and may increase HDLc.

- The active compound is included in the pharmaceutically acceptable carrier or diluent in an amount sufficient to deliver to a patient a therapeutic amount of compound in vivo in the absence of serious toxic effects.
- The concentration of active compound in the drug composition will depend on absorption, inactivation, and excretion rates of the drug as well as other factors known to those of skill in the art. It is to be noted that dosage values will also vary with the severity of the condition to be alleviated. It is to be further understood that for any particular subject, specific dosage regimens should be adjusted over time according to the individual need and the professional judgment of the person administering or supervising the administration of the compositions, and that the dosage ranges set forth herein are exemplary only and are not intended to limit the scope or practice of the claimed composition. The active ingredient may be administered at once, or may be divided into a number of smaller doses to be administered at varying intervals of time.
- A preferred mode of administration of the active compound for systemic delivery is oral. Oral compositions will generally include an inert diluent or an edible carrier. They may be enclosed in gelatin capsules or compressed into tablets. For the purpose of oral therapeutic administration, the active compound can be incorporated with excipients and used in the form of tablets, troches or capsules. Pharmaceutically compatible binding agents, and/or adjuvant materials can be included as part of the composition.
- The tablets, pills, capsules, troches and the like can contain any of the following ingredients, or compounds of a similar nature: a binder such as microcrystalline cellulose, gum tragacanth or gelatin; an excipient such as starch or lactose, a disintegrating agent such as alginic acid, Primogel, or corn starch; a lubricant such as magnesium stearate or Sterotes; a glidant such as colloidal silicon dioxide; a sweetening agent such as sucrose or saccharin; or a flavoring agent such as peppermint, methyl salicylate, or orange flavoring.

The compounds can also be administered in combination with nonsteroidal antiinflammatories such as ibuprofen, indomethacin, fenoprofen, mefenamic acid, flufenamic acid, sulindac. The compound can also be administered with corticosteriods.
- Solutions or suspensions used for parenteral, intradermal, subcutaneous, or topical application can include the following components: a sterile diluent such as water for injection, saline solution, fixed oils, polyethylene glycols, glycerine, propylene glycol or other synthetic solvents; antibacterial agents such as benzyl alcohol or methyl parabens; antioxidants such as ascorbic acid or sodium bisulfite; chelating agents such as ethylenediaminetetraacetic acid; buffers such as acetates, citrates or phosphates and agents for the adjustment of tonicity such as sodium chloride or dextrose. pH can be adjusted with acids or bases, such as hydrochloric acid or sodium hydroxide. The parenteral preparation can be enclosed in ampoules, disposable syringes or multiple dose vials made of glass or plastic.
- If administered intravenously, preferred carriers are physiological saline, bacteriostatic water, Cremophor EL™ (BASF, Parsippany, N.J.) or phosphate buffered saline (TBS).
- In a preferred embodiment, the active compounds are prepared with carriers that will protect the compound against rapid elimination from the body, such as a controlled release formulation, including implants and microencapsulated delivery systems. Biodegradable, biocompatible polymers can be used, such as ethylene vinyl acetate, polyanhydrides, polyglycolic acid, collagen, polyorthoesters and polylactic acid. Methods for preparation of such formulations will be apparent to those skilled in the art. The materials can also be obtained commercially from Alza Corporation and Nova Pharmaceuticals, Inc. Liposomal suspensions (including liposomes targeted to infected cells with monoclonal antibodies to viral antigens) are also preferred as pharmaceutically acceptable carriers. These may be prepared according to methods known to those skilled in the art, for example, as described in U.S. Pat. No. 4,522,811 (which is incorporated herein by reference in its entirety). For example, liposome formulations may be prepared by dissolving appropriate lipid(s) (such as stearoyl phosphatidyl ethanolamine, stearoyl phosphatidyl choline, arachadoyl phosphatidyl choline, and cholesterol) in an inorganic solvent that is then evaporated, leaving behind a thin film of dried lipid on the surface of the container. An aqueous solution of the compound is then introduced into the container. The container is then swirled by hand to free lipid material from the sides of the container and to disperse lipid aggregates, thereby forming the liposomal suspension.
- Suitable vehicles or carriers for topical application can be prepared by conventional techniques, such as lotions, suspensions, ointments, creams, gels, tinctures, sprays, powders, pastes, slow-release transdermal patches, suppositories for application to rectal, vaginal, nasal or oral mucosa. In addition to the other materials listed above for systemic administration, thickening agents, emollients and stabilizers can be used to prepare topical compositions. Examples of thickening agents include petrolatum, beeswax, xanthan gum, or polyethylene, humectants such as sorbitol, emollients such as mineral oil, lanolin and its derivatives, or squalene.
- Any of the compounds described herein for combination or alternation therapy can be administered as any derivative that upon administration to the recipient, is capable of providing directly or indirectly, the parent compound, or that exhibits activity itself. Nonlimiting examples are the pharmaceutically acceptable salts (alternatively referred to as “physiologically acceptable salts”), and a compound which has been alkylated or acylated at an appropriate position. The modifications can affect the biological activity of the compound, in some cases increasing the activity over the parent compound. This can easily be assessed by preparing the derivative and testing its anti-inflammatory activity according to known methods.

- The ability of a compound described herein to inhibit the expression of VCAM-1 or in the treatment of diseases in a host can be assessed using any known method, including that described in detail below.
- In Vitro MCP-1 Activity Assay
- Cultured human endothelial cells were seeded in 96-well plates. On the following day cells were stimulated with TNF-α (1 ng/ml) in the presence or absence of compounds dissolved in DMSO. To establish a dose curve an IC50, multiple concentrations in 2- to 5-fold increments were used. Cells were exposed to TNF-α and compounds for approximately 16 hours. The next day the cells were visually examined via light microscopy to score for visual signs of toxicity. Cell culture media, diluted 1:10, was analyzed by an MCP-1 immunoassay kit (R & D Systems). This assay is a sandwich immunoassay using immobilized anti-MCP-1 antibody in 96-well plate to capture secreted MCP-1 in cell culture media. Captured MCP-1 was subsequently detected with a horse radish peroxidase-conjugated anti-MCP-1 antibody for color development. Compound 3 expressed an IC50 values of >10(the amount of compound (μM) required to achieve a 50% reduction compared to control (cells stimulated with TNF-α only)).
- In Vitro VCAM-1 Assay
- Cell Culture and compound dosing: Cultured primary human aortic (HAEC) or pulmonary (HPAEC) endothelial cells were obtained from Clonetics, Inc., and were used below passage 9. Cells were seeded in 96 well plates such that they would reach 90-95% confluency by the following day. On the following day the cells were stimulated with TNF-α (1 ng/ml) in the presence or absence of compounds dissolved in DMSO such that the final concentration of DMSO is 0.25% or less. To establish a dose curve for each compound, four concentrations in 2- to 5-fold increments were used. Cells were exposed to TNF-α and compounds for approximately 16 hours. The next day the cells were examined under microscope to score for visual signs of toxicity or cell stress.
- Following 16 hr exposure to TNF-α and compound the media was discarded and the cells were washed once with Hanks Balanced Salt Solution (HBSS)/Phosphate buffered saline (PBS) (1:1). Primary antibodies against VCAM-1 (0.251 g/ml in HBSS/PBS+5% FBS) were added and incubated for 30-60 minutes at 37° C. Cells were washed with HBSS/PBS three times, and secondary antibody Horse Radish Peroxidase (HRP)-conjugated goat anti-mouse IgG (1:500 in HBSS/PBS+5% FBS) were added and incubated for 30 minutes at 37° C. Cells were washed with HBSS/PBS four time and TMB substrate were added and incubated at room temperature in the dark until there was adequate development of blue color. The length of time of incubation was typically 5-15 minutes. 2N sulfuric acid was added to stop the color development and the data was collected by reading the absorbance on a BioRad ELISA plate reader at OD 450 nm. The results are expressed as IC50 values (the concentration (micromolar) of compound required to inhibit 50% of the maximal response of the control sample stimulated by TNF-α only). Compounds exhibiting IC50's of less than 5 micromolar are tabulated in Biological Table 1.

Rheumatoid Arthritis Protocol - Male Lewis rats (150-175 g) from Charles River Laboratories were anesthetized on day 0 with 3-5% isoflurane anesthesia while the tail base was shaved and adjuvant mixture was injected. Fifty μL of adjuvant (10 mg/ml M. butyricum in mineral oil) was injected subcutaneously into two sites at the tail base. Paw swelling was monitored using a plethysmometer (UGO Basile), after shaving each leg to the level of the Achilles tendon to mark the level of immersion. A baseline paw measurement for both hindpaws was taken between d2-d5 and a second measurement was taken on day 7-8. Onset of paw swelling occurred rapidly between d9-11 and daily measurements were performed every weekday between d9 and day 15. Compounds of the invention and vehicles were dosed either prophylactically (d1-14), or therapeutically (d9-14) after swelling was confirmed. Solutions were injected subcutaneously or given orally by gavage 1-2 times per day. From day 0, rats were weighed every 2-3 days and overall health was monitored. Plasma drug levels, if desired, were measured in tail-vein derived blood samples taken on day 14. On day 15, blood samples were obtained by cardiac puncture, rats were euthanized with CO2, selected organs removed and both hindpaws were amputated and placed in 10% buffered formalin for histopathological analysis. See Biological Table 2.

Asthma Protocol - Balb/C mice (6-8 weeks old) are sensitized to ovalbumin (ova) (8 ug ova absorbed in 3.3 mg Alum inject) on days 0 and 5. On day 12, the mice were aerosol challenged with 0.5% ovalbumin dissolved in sterile saline for 1 hr in the AM, and then again in the PM (at least 4 hr apart). On day 14, the mice were anesthetized with ketamine/xylazine/acepromazine cocktail, exsanguinated, and then euthanized. Following blood collection, bronchoaveolar lavage was performed on each animal. Total cell counts were conducted on the lavage fluid, which was subsequently diluted with cell media 1:1. Slides of the lavage fluid were made by spinning the samples with a cytospin centrifuge. Slides were airdried and stained with x. Cell differentials of the lavage fluid were completed at the conclusion of the study. All compounds except Example 2 were well tolerated with no body weight loss throughout the course of the study. Statistical analysis involved ANOVA and Tukey-Kramer post hoc tests. Compounds were administered except where noted by subcutaneous injection once daily from day 0-13. The formulations used contained various mixtures of the following excipients (pharmasolve, cremdphor RH 40, tween 80, PEG 300). See Biological Table 3

Effect of Serum IgE Levels in Ovalbumin Sensitized Balb/c Mice - Peripheral blood samples were collected from ovalbumin (Calbiochem) or vehicle (2% Cremophor/Bicarbonate) treated Balb/c mice (Charles River) with or without administration of test compound (100 mg/kg/d, from day 0 to day 14). Serum was obtained by centrifugation and transferred into Microtainer serum tubes and frozen at −80° C. Mouse IgE ELISA Quantitation Kit (Bethyl Laboratories, Inc. Montgomery, Tex. or PharMingen, San Diego, Calif.) was applied to measure the IgE levels of serum samples. Immuno-reactions were performed as Kit protocol with IgE standard and serum samples in duplicates. The results were read in a microplate reader (Bio-Rad Model 550) at 450 nm and the amounts of IgE were calculated according to the standard curve. The limit of detection in our experiments was 7 ng/ml. Compound 3 administrated at 100 mg/kg/d from day 0 to day 14, reduced serum IgE levels by 38% in ovalbumin sensitized Balb/c mice compared with vehicle treated mice.
- Effect of Levels of IL-13, IL-5, IL-4, IFN-gamma and IL-2 mRNA in Mouse Lungs of Balb/c Mice with Ovalbumin Sensitization and Challenge
- Lung tissues were collected from ovalbumin (Calbiochem) or vehicle (2% Cremophor/Bicarbonate) sensitized Balb/c mice (Charles River) with or without treatment of test compound (100 mg/kg/d, from day 0 to day 14). Total RNA samples were isolated by the Trizol method: (Life Technologies, Grand Island, N.Y.) and quantitatively measured by UV spectrophotometer, as well as qualitatively examined by ethidum bromide stained gel electrophoresis. First strand cDNA templates were generated with oligo (dT) by Reverse Transcription Kit (invitrogen, Carlsbad, Calif.). The initial amounts of mRNA of each samples were quantitatively determined by running a SYBR Green (Qiagen, Valencia, Calif.) based real-time PCR (programmed as: initial denaturation at 95° C. for 15 minutes, denaturation at 95° C. for 15 seconds, annealing and elongation at 51±1° C. for 1 minute for total 40 cycles) with a specific pair of primers (IDT Corporation, Coralville, Iowa) and control primers for GAPDH in iCycler IQ Optical System (Hercules, Calif.). The data were statistically analyzed by ANOVA and t-tests with multiple comparisons of means (n=5 and P<0.05 were considered significant). Compound 3 administrated at 100 mg/kg/d, significantly inhibited ovalbumin induced levels of IL-13, IL-5 and IL-4 mRNA in the lung of Balb/c mice by 82%, 98% and 68% respectively; without significantly affecting IFN-gamma and IL-2 compared with vehicle treated mice.

Smooth Muscle Cell Proliferation Protocol - Human Aortic Smooth Mucle Cells (HAoSMC) were obtained from Clonetics, Inc. and were used below passage 10. Cells were seeded in 24-well plates. When cells were 80% confluent, they were made quiescent by adding media containing 0.2% serum (as compared to 5% serum in normal culture media) for 48 hours. The cells were, then, stimulated by 5% serum in the presence or absence of compounds dissolved in DMSO. To establish a dose curve and IC50 for each compound, multiple concentrations in the range of 20 to 0.05 μM were used. Rapamycin (at 1 and 0.1 μM) was used as a positive control for the assay. After a 20 hour incubation with or without test compounds, 3H-thymidine (0.5 μCi/well) was added to the cells for 4 hours of labeling. Washed cells were then lysed in NaOH and the amount of 3H-thymidine incorporation was determined. Cytotoxicity of the drug was measured by use of the CytolTox 96 assay kit (Promega, Madison, Wis.). Compound 3 had an IC50 of 0.5 μM.
- Effect of Test Compounds on LPS-Stimulated IL-1β
- Human peripheral blood mononuclear cells were treated with or without Compound 3 for 1 hour, then stimulated with LPS (1-2 μg/ml) for 3 hours. Condition media was collected and IL-1β measured using an ELISA kit. Compound 3 demonstrated a dose dependent inhibition of LPS-stimulated IL-1β secretion. See Biological Table 4

Reduction of Plasma TNF-α Levels and Lung VCAM-1 mRNA Levels in LPS-Challenged Mice. - Balb/C mice (6-8 weeks) were injected with LPS (1 mg/kg; 5 mls/kg) and sacrificed 2 hr later. Blood was collected for plasma TNF-α levels and lungs for measurement of VCAM-1 mRNA levels by quantitative RT-PCR. Compound 3 administered subcutaneously at a dose of 100 mg/kg/d, 2 hr prior to LPS injection, inhibited TNF-α production by 80% and VCAM-1 expression by 60% compared with vehicle controls.
- Disease Modifying Anti-Rheumatic Drug (DMARD) Activity in Rat Adjuvant Arthritis
- Compound 3 at twice daily subcutaneous doses of 60, 40 and 20 mg/kg/d was found to inhibit bone erosion in the ankle joint by histopathological analysis when administered prophylactically in the rat adjuvant arthritis model. The evaluation was carried out with hematoxylin and eosin stained ankle cross sections by a certified veterinary pathologist. When dosed prophylactically at doses of 100, 50 and 25 mg/kg/d, b.i.d., s.c., Compound 3 was also found to inhibit splenomegaly. Splenomegaly tracks with bone erosion in the adjuvant arthritis model and is thought to be a predictor of DMARDs activity.
- Modifications and variations of the present invention relating to compounds and methods of treating diseases will be obvious to those skilled in the art from the foregoing detailed description of the invention. Such modifications and variations are intended to come within the scope of the appended claims.
