FIELD: medicine, pharmaceutics. ^ SUBSTANCE: invention concerns a new glucitol derivative of formula (I): wherein m represents an integer chosen from 1-3; each R1, R2, R3 and R4 are independently choose from hydrogen atom and benzyl groups; Ar1 represents a naphthyl group which can be substituted by one or more substitutes chosen from the group, consisting of C1-C6alkyl group or halogen atom; A represents 5-7-members aromatic heterocyclic group containing one or more heteroatoms independently chosen from oxygen atom and sulphur atom which can form a condensed cycle with an aromatic carbocycle or an aromatic heterocycle where A can be substituted by one or more Rb provided when A is a benzocondensed cycle containing two or more rings, the group -(CH2)m- is connected with a heterocycle in A; Each Rb is independently chosen from C1-C6alkyl group, halogen atom and C1-C6-alkoxy group; or to their pharmaceutically acceptable salts. These compounds are used as a Na+ cotransport inhibitor and exhibits ability to reduce blood sugar level. ^ EFFECT: invention covers a pharmaceutical composition based on these compounds and to the method for treatment and prevention of such diseases associated with hyperglycemia, as diabetes, diabetes complications and obesity. ^ 12 cl, 4 tbl, 5 ex |
