NEW HETEROCYCLIC FLUORGLUCOSIDE DERIVATIVES, MEDICATIONS CONTAINING THESE COMPOUNDS, AND THEIR APPLICATION Russian patent published in 2008 - IPC C07H17/00 C07H17/02 A61K31/7056 A61K31/7042 A61P3/10 

FIELD: chemistry.

SUBSTANCE: invention concerns substituted heterocyclic fluorglucoside derivatives of the formula (I) , where R1 and R2 are independently F, H, or one of R1 or R2 residues is OH; R3 is OH or F, so that at least one of R1, R2, R3 residues is F; R4 is OH; A is O; X is C or N, so that if Y = S, X should be C; Y is N or S; m = 1; R5 is hydrogen, OH or (C₁-C₆)-alkyl optionally mono- or polysubstituted by fluorine; R6 is H or (C₁-C₆)-alkyl, if required; or, if Y = S, R5 and R6 form phenyl together with carbon atoms to which they are linked; B is (C₁-C₆)-alcandiyl or -CO-NH-CH2-; n = 2 or 3; Cyc1 is phenyl or thiophenyl; R7 is hydrogen, F, CI, Br, J, (C₁-C₆)-alkyl or (C₁-C₆)-alkoxy optionally mono- or polysubstituted by fluorine; R8 is hydrogen or halogen; R9 is hydrogen; or R8 and R9 together mean -CH=CH-CH=CH-, -CH=CH-C((C₁-C₆)-alkoxy)=CH- or -OH=CH-O- and together with carbon atoms to which they are linked form Cyc2, which is phenyl, optionally substituted (C₁-C₆)-alkoxy or furanyl respectively; and their pharmaceutically acceptable salts.

EFFECT: obtaining efficient medicine for sugar level decrease in blood.
