FIELD: chemistry.SUBSTANCE: invention relates to novel derivative of purinylpyridinylamino-2,4-difluorophenylsulphonamide of formula 1 and its pharmaceutically acceptable salt. Compounds have properties of inhibiting Raf-kinase super activity and can be applied for prevention and treatment of diseases, mediated by activity of Raf-kinase, such as cancer, in particular melanoma. In formula 1 R stands for methyl; ethyl; propyl; isopropyl, butyl, isobutyl; cyclopropyl; cyclobutyl; cyclopentyl; cyclohexyl; C-Caryl, unsubstituted or substituted with one or more substituents, selected from the group, which consists of chlorine, fluorine, bromine, methyl, ethyl, propyl, isopropyl, butyl, isobutyl, methoxy, ethoxy, propoxy, butoxy, trifluoromethoxy, fluoromethoxy, difluorimethoxy and trifluoroethoxy; C-Cheteroaryl, which consists of one or two rings, non-substituted or substituted with one or more substituents, selected from the group, which consists of chlorine, fluorine, bromine, methyl, ethyl, propyl, isopropyl, butyl, isobutyl, methoxycarbonyl, ethoxycarbonyl, propoxycarbonyl, butoxycarbonyl, tret- butoxycarbonyl and dioxolanyl; C-Cheterocycloalkyl, non-substituted or substituted with one or more substituents, selected from the group, which consists of chlorine, fluorine, bromine, methyl, ethyl, propyl, isopropyl, butyl, isobutyl; or C-Caryl-linear or branched C-Calkyl, non-substituted or substituted with one or more substituents, selected from the group, which consists of chlorine, fluorine, bromine, nitro, methyl, ethyl, propyl, isopropyl, butyl and isobutyl, and heteroaryl and heterocycloalkyl contain in ring one or more heteroatoms, selected from the group, which consists of N, O and S. Invention also relates to methods of obtaining formula 1 compounds.EFFECT: improvement of characteristics.15 cl, 3 tbl, 51 ex 1 dwg |
