FIELD: organic chemistry, biochemistry, medicine, pharmacy. ^ SUBSTANCE: invention relates to novel condensed cyclopropylpyrrolidines of the formula: wherein x means 0 or 1 and y means 0 or 1 under condition that x means 1 when y means 0, and x means 0 when y means 1; and wherein n means 0 or 1; X means hydrogen atom (H) of group -CN; R1, R2, R3 and R4 are similar or different and chosen independently from H, (C1-C10)-alkyl, (C2-C12)-alkenyl, saturated (C3-C10)-cycloalkyl, saturated (C3-C10)-cycloalkyl-(C1-C10)-alkyl, saturated (C3-C10)-bicycloalkyl, saturated (C3-C10)-tricycloalkyl, hydroxyl-(C1-C10)-alkyl-saturated (C3-C10)-cycloalkyl, (C1-C10)-alkylthio-(C1-C10)-alkyl, (C6-C10)-aryl-(C1-C10)-alkylthio-(C1-C10)-alkyl, (C6-C10)-aryl-(C1-C10)-alkyl, 5- or 6-membered heteroaryl comprising one nitrogen atom (N) or one oxygen atom (O), 5- or 6-membered heteroaryl comprising one atom N condensed with (C6-C10)-aryl ring, 5- or 6-membered heteroaryl comprising one atom N or one atom O, (C1-C10)-alkyl, cycloheteroalkyl that represents (C5-C8)-saturated ring comprising one heteroatom, such as N or O; if necessary, all compounds comprise 1, 2, 3, 4 or 5 groups of substitutes at corresponding carbon atom chosen from halogen atom, (C1-C10)-alkyl, (C2-C12)-alkenyl, hydroxy-group, hydroxy-(C1-C10)-alkyl or cyano-group; R1 and R4 can form in common, if necessary, the group -(CR5R6)m- wherein m means 2-6, and R5 and R6 are similar or different and chosen independently from hydroxy-group, H or (C1-C10)-alkyl including all their stereoisomers; and their pharmaceutically acceptable salt, or prodrug esters and all their stereoisomers. These compound inhibit activity of dipeptidyl peptidase IV that allows their using in pharmaceutical compositions used in treatment of diabetes mellitus of type-2. ^ EFFECT: valuable medicinal properties of compounds. ^ 20 cl, 6 tbl, 113 ex |
