FIELD: medicine. ^ SUBSTANCE: invention refers to new pyridine derivatives or to their pharmaceutically acceptable salts of general formula 1: wherein R1, R2, R3, R4, R5, R6 and R7 are independently chosen from the group including hydrogen atom, halogen, amino, C1-C6lower alkyl, C2-C6lower alkenyl, C1-C6lower alkoxy, C1-C10alkylamino, C4-C9cycloalkylamino, C4-C9heterocycloalkylamino, C1-C10aralkylamino, arylamino, acylamino, saturated heterocyclyl, acyloxy, aryl, heteroaryl, C1-C10aralkyl, aryloxy; X represents oxygen or sulphur atom; Y represents oxygen atom or N-R8, wherein R8 is chosen from the group including hydrogen atom; aforesaid aryl group is chosen from phenyl, naphthyl and condensed phenyl group; aforesaid heteroaryl and saturated heterocyclic groups represent pentagonal or hexagonal heterocyclic ring containing 1 to 2 heteroatoms chosen from oxygen, nitrogen and sulphur atom; or condensed heterocyclic ring; and aforesaid aryl and heteroaryl groups are those that 1 to 4 assistants chosen from group including halogen, C1-C6lower alkyl, C1-C6lower alkoxy are substituted. And specified compounds or their pharmaceutically acceptable salt of formula 1 are not compounds as follows 6-methyl-3,4-dihydro-pyrano[3,4-c]pyridin-1-one, 5-vinyl-3,4-dihydro-pyrano[3,4-c]pyridin-1-one, 6-methyl-8-furan-2-yl-3,4- dihydropyrano[3,4-c]pyridin-1-one, 3-tert-butyl-5,6,7,8-tetrahydro-[2,7]naphthyridine-8-one and dimethyl ether (3S)-6,8-dimethyl-1-oxo-1,2,3,4-tetrahydro-[2,7]naphthyridine-3,5-dicarboxylic acids. ^ EFFECT: compounds possess inhibitory action with respect to formation of cytokines involved in inflammatory reactions, can be used as a therapeutic agent for treatment of inflammatory diseases, immune diseases, chronic inflammations; it provides antiinflammatory and analgesic action. ^ 21 cl, 7 tbl, 144 ex |
