FIELD: pharmaceutical chemistry. ^ SUBSTANCE: invention relates to phenylpyridazine derivative of general formula I , wherein R1 represents C1-C12-alkyl optionally comprising cyclic C3-C6-alkyl structures and optionally substituted by phenyl, which may be substituted by 1-2 halogen atoms; or C1-C12-alkenyl substituted by optionally halogen-substituted phenyl; R2 and R3, independently form each other, represent hydrogen, C1-C12-alkyl, C1-C12-hydroxyalkyl, C1-C12-dihydroxyalkyl, or C1-C12-alkynyl; or R2 and R3, together with adjacent nitrogen atom form 5-6-membered saturated heterocyclic group containing 1-2 nitrogen atoms and optionally oxygen atom, indicated heterocyclic group being optionally substituted by C1-C12-alkyl group, C1-C12-alkoxydicarboxylic group or phenyl-C1-C7-alkyl group; X, Y, and Z, independently form each other, represent hydrogen, halogen, optionally halogen(s)-substituted C1-C12-alkyl, C1-C12-alkoxy, C1-C12-alkylthio, C1-C12-alkylsulfinyl, C1-C12-alkylsulfonyl, or phenyl; and n is a number from 0 to 5; provided that R2 and R3 cannot be simultaneously hydrogen atoms or identical C1-C3-alkyl groups when R1 is benzyl or C1-C3-alkyl group; and salts of compounds I. Foregoing compounds manifest inhibitory activity against production of interleukin IL-1beta being well dissoluble in water and characterized by good oral absorption. Invention also relates to therapeutical agent inhibiting production of interleukin 1beta, pharmaceutical composition, employment of above-defined compounds, a method for treating disease caused by interleukin 1beta production stimulation as well as methods for treating immune system disturbances, inflammatory conditions, ischemia, osteoporosis, or septicemia using above compounds. ^ EFFECT: expanded therapeutical possibilities. ^ 22 cl, 4 dwg, 2 tbl, 217 ex |
