CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit under 35 U. S. C. § 119(e) of U.S. Provisional Patent Application No. 60/851 ,467 filed October 12, 2006 which application is incorporated herein by reference in its entirety.

BACKGROUND

Technical Field

The present invention relates generally to compounds and methods for obtaining oligosaccharide mimics, and more particularly for obtaining oligosaccharide mimics by incorporating or substituting in a cyclohexane derivative.

Description of the Related Art

Naturally occurring monosaccharides and oligosaccharides play a role, or are capable of playing a role, in a variety of biological processes. In certain cases, non-naturally occurring monosaccharides and oligosaccharides may serve to replace or even improve upon their naturally occurring counterparts. Monosaccharides and particularly oligosaccharides may be difficult, and thus costly, to produce. Even where the degree of difficulty to produce is not particularly elevated, the production of monosaccharides and oligosaccharides may still nevertheless be costly. This problem is multiplied where a costly monosaccharide or oligosaccharide needs to be mass produced. While mimics of monosaccharides and oligosaccharides ("glycomimetics") may improve upon their biological properties, the cost of producing the mimics may not be significantly reduced relative to that which they mimic. Accordingly, there is a need in the art for reducing the production cost or complexity of glycomimetics. The present invention fulfills these needs and further provides other related advantages.

DETAILED DESCRIPTION As noted above, the present invention provides compounds and methods for obtaining monosaccharide and oligosaccharide mimics. Such mimics have a variety of uses in vitro and in vivo, including as antagonists of E-selectin.

Within the present invention, an oligosaccharide mimic may be prepared by incorporating one or more cyclohexane derivatives into an oligosaccharide or glycomimetic compound. An oligosaccharide refers to two or more monosaccharides covalently joined. Oligosaccharides are polymers containing monosaccharide units, typically with 2 to about 100 monosaccharides and any integer in-between. Each monosaccharide of an oligosaccharide is independently selected; although two or more monosaccharides may be identical.

The cyclohexane derivative of the methods of the present invention has the formula:

The cyclohexane derivative is attached to the oligosaccharide or glycomimetic compound at least at one of the OH, the R¹ or the R². In embodiments, attachment is at least at one of the OH or the R². Other options for attachment include at both of the OH, e.g., one monosaccharide or monosaccharide mimic attached at one of the OH and another monosaccharide or monosaccharide mimic attached at the other OH. Such a cyclohexane derivative may also be used in a method for substituting a monosaccharide mimic (a cyclohexane derivative) for at least one hexose or hexosamine. The hexose or hexosamine may be in an oligosaccharide or glycomimetic compound or in an oligosaccharide or glycomimetic possessed by an oligosaccharide-containing or glycpmimetic- containing compound. Such a substitution is accomplished by replacing one or more hexose or hexosamine in an oligosaccharide or glycomimetic compound with a cyclohexane derivative. If it is more than one, then each is independently selected. Examples of oligosaccharide-containing compounds include glycoproteins, glycopeptides, glycolipids and glyconucleic, acids. As used herein, a "Ci-Ce alkanyl" refers to an alkane substituent with one to eight carbon atoms and may be straight chain, branched or cyclic (cycloalkanyl). Examples are methyl, ethyl, propyl, isopropyl, butyl and t-butyl. A "halogenated CrCe alkanyl" refers to a "CrC₈ alkanyl" possessing at least one halogen. Where there is more than one halogen present, the halogens present may be the same or different or both (if at least three present). A "CrC₈ alkenyl" refers to an alkene substituent with one to eight carbon atoms, at least one carbon-carbon double bond, and may be straight chain, branched or cyclic (cycloalkenyl). Examples are similar to "CrC₈ alkanyl" examples except possessing at least one carbon-carbon double bond. A "CrC₈ alkynyl" refers to an alkyne substituent with one to eight carbon atoms, at least one carbon-carbon triple bond, and may be straight chain, branched or cyclic (cycloalkynyl). Examples are similar to "CrCs alkanyl" examples except possessing at least one carbon-carbon triple bond. An "alkoxy" refers to an oxygen substituent possessing a "CrC₈ alkanyl," "CrC₈ alkenyl" or "C_rC₈ alkynyl." This is -O-alkyl; for example methoxy, ethoxy, n-propoxy, i-propoxy, n-butoxy and the like; and alkenyl or alkynyl variations thereof (except for methoxy). It further refers to the group O-alkyl-W-alkyl where W is O or N; for example -O-(CH2)_n-W-(CH₂)m where n and m are independently 1-10. An "aryl" refers to an aromatic substituent with one to fourteen carbon atoms in one or multiple rings which may be separated by a bond or fused. A "heteroaryl" is similar to an "aryl" except the aromatic substituent possesses at least one heteroatom (such as N, O or S) in place of a ring carbon. Examples of aryls and heteroaryls include phenyl, naphthyl, pyridinyl, pyrimidinyl, triazolo, furanyl, oxazolyl, thiophenyl, quinolinyl and diphenyl. As used herein, the term "independently selected" refers to the selection of identical or different substituents. "Me" and "Et" represent methyl and ethyl, respectively. "Bz" represents benzoyl. "Ar" represents aryl. Examples of physiologically acceptable salts include Na, K, Li, Mg and Ca. Monosaccharide substituents recited herein (e.g., D-mannose, L-galactose, D-arabinose and L-fucose) may be in the furanose, pyranose or open form.

A linker arm may be desirable for attachment, for example, to a monosaccharide, a monosaccharide mimic or something else such as an amino acid, nucleic acid or lipid. A linker may include a spacer group, such as — (CH₂)n — or — O(CH₂)n — where n is generally about 1-20 (all number ranges disclosed herein include any whole integer range therein). An example of a linker is — NH₂, e.g., — CH₂ — NH₂ when it includes a short spacer group. Embodiments of linkers include the following:

Squaric acid Thiourea

Dithiadiazoleoxide Acylation via Thiofuran

H O H O O H I Il -N-C- (CH₂)₂— CH₂-NH- N-C- (CH₂)n— C-N-

Other linkers with or without a spacer group (e.g., CONH(CH₂^NH₂, COOMe, or polyethylene glycol or derivative) will be familiar to those in the art or in possession of the present disclosure. Alternatively, or in combination with a linker arm, a cyclohexane derivative may be attached at one or both OH.

EXAMPLES

EXAMPLE 1 SYNTHESIS OF GICNAC MIMIC FROM TETRAHYDROPHTHALIC ANHYDRIDE (Fig. 1 )

Synthesis of intermediate I: Amberlyste 15 (50.0 g) was placed in a flask and dried in high vacuo for 1 h. Methanol (1 I) was added, followed by cis-1 ,2,3,6- tetrahydrophthalic anhydride (50.0 g, 328 mmol) and trimethylorthoformate (100 ml, 914 mmol). The reaction mixture was then vigorously stirred. After 5 days, additional trimethylorthoformate (50 ml, 457 mmol) was added. The reaction was stopped after 9 days (TLC-control: petroleum ether/Et₂θ, 1 :2), filtered over celite and washed with methanol. The solvent was removed in vacuo (20 mbar). The brown residue was transferred with CH₂Cb (150 ml) into a separation funnel and washed with satd. NaHCO₃ solution and brine (each 150 ml). The aqueous layers were extracted 3 times with CH₂CI₂ (3x 150 ml). The combined organic layers were dried over Na₂SO^ filtered and concentrated in vacuo (20 mbar) to afford diester I as a brownish oil (57.5 g, 88%).

Synthesis of intermediate II:

To a stirred suspension of diester I (2.00 g, 10.1 mmol) in pH 7.00 phosphate buffer solution (103 ml, 0.07 M), PLE (8.00 mg, 216 units) was added. The pH was kept at 7 by adding continuously NaOH solution (1.0 M) via syringe pump. The reaction was stirred at 2O⁰C until one equivalent of NaOH (10 ml) was used (56.5 h, TLC-control: petroleum ether/Et₂O, 1 :2). The reaction mixture was transferred into a separation funnel with ethyl acetate (100 ml). The layers were separated and the organic layer was extracted twice with pH 7.00 phosphate buffer solution (2x 60 ml). The combined aqueous layers were acidified to pH 2 with 1 M HCI solution and extracted four times with ethyl acetate (4x 150 ml). To separate the layers NaCI was added. The combined organic layers were dried over Na₂SO₄, filtered and concentrated in vacuo to afford the monoester Il as a yellowish oil (1.67 g, 90%). 96.0% ee. (GC), 96.4% ee. (rot.), [α]_D ²¹ + 15.23° (c = 0.195, EtOH), (Lit. + 15.8° (c = 0.2, EtOH), [Angew. Chem. Int. Ed. Engl., 1984, 23, 142]).

Synthesis of intermediate III:

A solution of monoester Il (0.992 g, 5.38 mmol) in dry CH₂CI₂ (18 ml) was treated with (COCI)₂ (0.7 ml, 8.15 mmol) and DMF (14 μl), stirred for 3 h at r.t. and evaporated (rotavapor purged with argon). A solution of the residue in dry THF (20 ml) was added dropwise over a period of 20 minutes to a boiling suspension of 2-mercaptopyridine-1 -oxide sodium salt (974.8 mg, 6.49 mmol), t-BuSH (3.1 ml, 27.5 mmol), and 4-DMAP (26.3 mg, 0.216 mmol) in dry THF (50 ml). The solution was stirred at reflux for 3h (TLC-control:, petroleum ether/Et₂O, 10:1). The reaction mixture was then cooled down to r.t. (room temperature) and transferred into a separation funnel with ethyl acetate (50 ml) and washed with water (100 ml). The aqueous layer was extracted twice with ethyl acetate (2x 100 ml). The combined organic layers were dried: over Na₂SO₄, filtered and concentrated in vacuo (200 mbar). The crude product was purified by column chromatography (petroleum ether/Et₂O, 30:1 to 15:1 ) to afford methylester III as a yellowish oil (584.9 mg, 83%). [α]_D ²¹ + 78.23° (c = 1.010, CHCI₃).

Synthesis of intermediate IV:

To a stirred suspension of methylester III (5.19 g, 37.0 mmol) in pH 7.00 phosphate buffer solution (520 ml, 0.07 M), PLE (51.2 mg, 1382 units) was added. The pH was kept at 7 by adding NaOH solution (1.0 M) via syringe pump. The reaction was stirred at r.t. until one equivalent of NaOH (37 ml) was used (11 h, TLC-control: petroleum ether/Et₂θ, 1 :1 ). The reaction mixture was transferred into a separation funnel and washed twice with ethyl acetate (2x 300 ml). The layers were separated and the organic layers were extracted twice with pH 7.00 phosphate buffer solution (2x 300 ml). The combined aqueous layers were acidified to pH 2 with aqueous HCI (30 ml, 4 M) and extracted three times with ethyl acetate (3x 400 ml). The combined organic layers were dried over Na₂SO₄, filtered and concentrated in vacuo (100 mbar). The crude product was filtered through a short plug of silica affording acid IV as a pale yellowish oil (3.92 g, 84%). 96.3% ee. (GC), 94.3% ee.

Synthesis of intermediate V: Acid IV (8.30 g, 65.7 mmol) was placed in a flask purged with argon and suspended in water (180 ml). The reaction mixture was cooled down to O⁰C and NaHCO₃ (16.6 g, 197 mmol) was added, followed by a solution of Kl (65.4 g, 394 mmol) and iodine (17.5 g, 68.9 mmol) in water (150 ml). The reaction was stirred at r.t. for 24 h and then extracted three times with CH2CI2 (3x 60 ml). The combined organic layers were washed with a solution of

Na₂S₂O₃ (50 g) in water (250 ml). The aqueous layer was extracted twice with CH₂CI₂ (2x 60 ml). The combined organic layers were protected from light, dried over Na₂SO₄, filtered and concentrated in vacuo (20 mbar) and quickly in high vacuo to afford iodolactone V as an off-white solid (15.79 g, 95%). [α]o²¹ + 35.96° (c = 0.565, CHCI₃).

Synthesis of intermediate Vl:

Iodolactone V (15.73 g, 62.2 mmol) was dissolved in dry THF (340 ml). Then DBU (14 ml, 93.3 mmol) was added and the mixture was refluxed for 20 h (TLC-control: petroleum ether/Et₂O, 1 :1 ). The reaction mixture was cooled down to r.t., transferred with Et₂O (200 ml) into a separation funnel and extracted with aqueous HCI (400 ml, 0.5 M) and brine (400 ml). The aqueous layers were extracted three times with Et₂O (3x 200 ml). The combined organic layers were dried over Na₂SO₄, filtered and concentrated in vacuo (350 mbar).

EXAMPLE 13 E-SELECTIN ASSAY

E-selectin Protocol: The inhibition assay to screen glycomimetic antagonists of E-selectin is a competitive binding assay, which allows the determination of IC50 values. Briefly, E-selectin/lg chimera is immobilized by incubation at 37⁰C in 96 well microtiter plates for 2 hours. To reduce nonspecific binding, bovine serum albumin is added to each well and incubated at room temperature for 2 hours. The plate is washed and serial dilutions of the test compounds are added to the wells in the presence of conjugates of biotinylated, sLe^a polyacrylamide with streptavidin/horseradishperoxidase and incubated for 2 hours at room temperature. To determine the amount of sLe^a bound to immobilized E-selectin after washing, the peroxidase substrate, 3,3\5,5¹ tetramethylbenzidin (TMB) is added. After 3 minutes, the enzyme reaction is stopped by the addition of H₃PO₄ and the absorbance of light at a wavelength of 450 nm is determined. The concentration of test compound required to inhibit binding by 50% is determined and reported as the IC50 value for each glycomimetic E-selectin antagonist. In addition to reporting the absolute IC5₀ value as measured above, relative IC₅₀ values are determined by a ratio of the IC₅₀ measured for the test compound to that of a glycomimetic internal control (reference) for each assay. The results from the testing in this assay of several of the compounds disclosed herein are shown below.
