AMINOBENZIMIDAZOLE DERIVATIVES AS INHIBITORS OF RESPIRATORY SYNCYTIAL VIRUS REPLICATION Russian patent published in 2008 - IPC C07D401/06 

FIELD: chemistry.

SUBSTANCE: invention relates to aminobenzimidazole and their pharmaceutical compositions having inhibitor potency towards respiratory syncytial virus replication. Aminobenzimidazole is of formula (I) where Q represents Ar², C_3-7cyclalkyl or substituted C_1-6alkyl; G represents methylen; R¹ represents optionally substituted pyridile; one of R^2a and R^3a represents C_1-6alkyl, and other from R^2a and R^3a represents hydrogen, in the case if R^2a differs from hydrogen R^2b represents hydrogen or C_1-6alkyl, and R^3b represents hydrogen if R^3a differs from hydrogen or C_1-6alkyl, and R^2b represents hydrogen, or all R^2a, R^2b, R^3a and R^3b represent hydrogen; R⁵ represents hydrogen; Ar² represents optionally substituted phenyl.

EFFECT: production of the new biologically active compounds on basis of aminobenzimidazole.
