FIELD: organic chemistry, medicine, pharmacy. ^ SUBSTANCE: invention relates to novel compounds of the formula (I): or its pharmaceutically acceptable salts that possess properties of CB2 receptors agonist and can be used in preparing drugs exerting analgesic effect, in particular, for pain treatment. In compound of the formula (I) R1 is chosen from group consisting of (C1-C6)-alkyl, (C3-C6)-cycloalkyl, (C3-C6)-cycloalkyl-(C1-C6)-alkyl, (C2-C6)-alkenyl, R4 2N-(C1-C6)-alkyl, R4 2NC(=O)-(C1-C6)-alkyl, R4O-(C1-C6)-alkyl, R4OC(=O)-(C1-C6)-alkyl, R4C(=O)-(C1-C6)-alkyl, R4C(=O)-NR4-(C1-C6)-alkyl, R4 2NSO2-(C1-C6)-alkyl, R4 2NC(=O)-NR4-(C1-C6)-alkyl, radicals phenyl-(C1-C6)-alkyl, heteroaryl-(C1-C6)-alkyl, heterocycloalkyl-(C1-C6)-alkyl, bicyclic heteroaryl-(C1-C6)-alkyl; Ar represents phenyl or pyridyl; R2 represents (C1-C6)-alkyl that is unsubstituted or substituted at 1-6 carbon atoms with one or more fluorine atom substitute or (C3-C6)-cycloalkyl; R3 is chosen from the following group consisting of: (a) , (b) , (c) , (d) , (e) , (f) , (g) , (h) , (i) , (j) and (k) ; R4 represents group chosen independently from group consisting of hydrogen atom (H), (C1-C6)-alkyl, (C2-C6)-alkenyl; groups R5 are chosen independently from group consisting of H, (C2-C6)-alkenyl; groups R6 are chosen independently from group consisting of H, (C1-C6)-alkyl, (C3-C6)-cycloalkyl, (C2-C6)-alkenyl, heterocyclyl, radical (C1-C3)-alkyl, phenyl, radical phenyl-(C1-C3)-alkyl, heteroaryl, radicals heteroaryl-(C1-C3)-alkyl, bicyclic heteroaryl and bicyclic heteroaryl-(C1-C3)-alkyl; R5 and R6 can be combined to form 5-7-membered heterocycle; X is chosen from group consisting of -C(R5)2-, -NR5-, C(=O)-, -CH2-CH2-, CH=CH- and -C(R)(R') wherein R and R' represent (C1-C6)-alkyl, -OR'' or H and R'' represents H; Y represents -CH or nitrogen atom and wherein heterocyclyl or heterocycloalkyl represent 5-6-membered ring comprising from 1 to 2 heteroatoms chosen from nitrogen (N) and oxygen (O) atoms that is unsubstituted or substituted with (C1-C6)-alkyl; heteroaryl represents heteroaromatic 5-6-membered ring comprising from 1 to 2 heteroatoms chosen from N, S and sulfur atom (S) that is unsubstituted or substituted with group chosen from group consisting of (C1-C6)-alkyl, nitro-group, halogen atom and acetoxymethyl; bicyclic heteroaryl represents 5-6-membered nitrogen-containing ring condensed with benzene ring. Also, invention relates to a pharmaceutical composition and a method for paintreatment. ^ EFFECT: valuable medicinal properties of compounds and pharmaceutical composition. ^ 9 cl, 15 sch, 3 tbl, 130 ex |
