Abstract
The present invention pertains to the field of medicine, more precisely to that of pharmacology, and essentially relates to synthetic biologically active compounds that consist of substituted aminomethylphosphonates. The purpose of this invention is to produce new chemical compounds having an extended biological activity, mainly an antiviral activity (against the herpes simplex viruses) and an antimicrobial activity. In other words, the purpose of this invention is to achieve the chemical synthesis of new biologically active substances outmatching the existing analogs on several points, mainly on the extent of the action. To this end, this invention provides the synthesis of dialkyl-1-aryl-1-(2,4-dioxo-5-amino-1,3-pyrimidin-5-yl)methylphosphonates of the general formula (I) where R1 is alkyl, halogen, hydroxyl or nitro and R2 is alkyl or HCF2CF2CH2. This invention also relates to a general methodology for producing these compounds, to a synthesis example, to a list of 13 synthesised and tested substances, to their identification results and to experimental data concerning 3 series of comparative verification of their biological properties and of their toxicity.
