FIELD: chemistry.
SUBSTANCE: invention relates to compounds of formula (I) and their pharmaceutically acceptable salts of formula (I) where n equals 0, 1 or 2, A is a five- or six-member aromatic ring which optionally contains one or two heteroatoms independently selected from nitrogen, oxygen or sulphur, B is a 5-9-member ring containing 0 or 1 double bonds and optionally contains an additional heteroatom selected from nitrogen and oxygen; where the ring optionally contains one or two substitutes independently selected from a group comprising C1-C6-alkoxy, C1-C6-alkoxycarbonyl, C1-C6-alkyl, carboxy, cyano, hydroxy, hydroxy-C1-C6-alkyl, di-C1-C6-alkylamino-C1-C6-alkyl, (NR4R5)-carbonyl or oxo; R1 is selected from -C(O)NR4R5 - CO2R4, 5-tetrazolyl, cyano; each R2 is independently selected from a group comprising C1-C6-alkyl, amino, benzyloxy, halogen, hydroxyl; R3 is a 5-7-member cycloalkyl ring; values of the rest of the radicals are given in the formula of invention. The invention also relates to a method for synthesis of the said compounds, a method of inhibiting HCV replicon function and a method of inhibiting functioning of the HCV NS5B protein.
EFFECT: wider field of use of the compounds.
