FIELD: organic chemistry, medicine, pharmacy. n SUBSTANCE: invention proposes phenylpyridazine compounds represented by the following formula (I): wherein R 1 represents unsubstituted or substituted phenyl wherein substitutes are taken among the group comprising halogen atom, lower alkyl, lower alkoxy-group and phenylthio-group, or pyridyl; R 2 represents lower alkoxy-group, lower alkylthio-group, lower alkylsulfinyl or lower alkylsolfonyl; R 3 represents hydrogen atom or lower alkoxy-group; or R 2 and R 3 can be condensed in common forming lower alkylenedioxy-group; R 4 represents cyano-group, carboxyl, unsubstituted or substituted lower alkyl wherein substitutes are taken among the group comprising hydroxyl, carboxyl and N-hydroxy-N-lower alkylaminocarbonyl; lower alkenyl; lower alkylthio-group; lower alkylsulfinyl; lower alkylsulfonyl; lower alkylsulfonyloxy; unsubstituted or substituted phenoxy-group wherein substitutes are taken among the group comprising halogen atom, lower alkoxy-, nitro-, cyano-group; unsubstituted phenylthio-group or phenylthio-group substituted with halogen atom; pyridyloxy-; morpholino-group; morpholinylcarbonyl; 1-piperazinylcarbonyl substituted with lower alkyl; unsubstituted or substituted amino-group wherein substitutes are taken among the group comprising lower alkyl, benzyl, phenyl that can be substituted with halogen atoms or lower alkoxy-groups, and n = 0, or their salts. Proposed compounds possess the excellent inhibitory activity against biosynthesis of interleukin-1β and can be used in preparing a medicinal agent inhibiting biosynthesis of interleukin-1β, in particular, in treatment and prophylaxis of such diseases as diseases of immune system, inflammatory diseases and ischemic diseases. Also, invention proposes intermediate compounds for preparing compounds of the formula (I). Except for, invention proposes a medicinal agent and pharmaceutical composition that inhibit biosynthesis of interleukin-1β and inhibitor of biosynthesis of interleukin-1β. n EFFECT: valuable medicinal properties of compounds and composition. n 7 cl, 1 tbl, 66 ex |
