Hydrazine derivatives of the formula
wherein Y is CO or SO2; R1 is lower alkyl, lower alkenyl, lower cycloalkyl, lower cycloalkyl-lower alkyl, aryl or aryl-lower alkyl; R2 is lower alkyl, halo-lower alkyl, aryl-lower alkyl, aryl-lower alkenyl or aryl when Y is SO2 and is lower alkyl, halo-lower alkyl, lower alkoxy, lower alkoxycarbonyl, acyl, lower cycloalkyl, aryl, aryl-lower alkyl, aryl-lower alkoxy or NR5R6 when Y is CO; and R3 is hydrogen, lower alkyl optionally substituted by cyano, amino, hydroxy, lower alkoxy, lower alkoxycarbonyl, heterocyclyl or heterocyclylcarbonyl, lower alkenyl, lower alkynyl, lower cycloalkyl, lower cycloalkyl-lower alkyl, aryl-lower alkyl, aryl-lower alkenyl, aryl or heterocyclyl; or R2 and R3 together form the residue of a 5-, 6- or 7-membered cyclic amide, cyclic imide, cyclic sulphonamide or cyclic urethane group; R4 is lower alkyl, hydroxy-lower alkyl, lower alkenyl, lower cycloalkyl, lower cycloalkyl-lower alkyl or a group of the formula X-aryl, X-heteroaryl or —(CH2)1-2—CH═CR7R8; X is a spacer group; R5 and R6 each individually are hydrogen, lower alkyl or aryl-lower alkyl; and R7 and R8 together represent a lower alkylene group in which one methylene group is optionally replaced by a hetero atom; and their pharmaceutically acceptable salts inhibit not only the release of tumour necrosis factor (TNF-&agr;) and transforming growth factor (TGF-&agr;) from cells, but also keratinocyte proliferation. They are useful as medicaments, especially for the treatment of inflammation, fever, hemorrhage, sepsis, rheumatoid arthritis, osteoarthritis, multiple sclerosis or psoriasis.
氢肼衍生物的化学式为其中Y为CO或SO2;R1为较低的烷基、较低的烯基、较低的环烷基、较低的环烷基-烷基、芳基或芳基-烷基;R2为较低的烷基、卤代较低的烷基、芳基-烷基、芳基-烯基或芳基(当Y为SO2时),且为较低的烷基、卤代较低的烷基、较低的烷氧基、较低的烷氧羰基、酰基、较低的环烷基、芳基、芳基-烷基、芳基-烷氧基或NR5R6(当Y为CO时);R3为氢、较低的烷基(可选择地被氰基、氨基、羟基、较低的烷氧基、较低的烷氧羰基、杂环烷基或杂环烷基羰基取代)、较低的烯基、较低的炔基、较低的环烷基、较低的环烷基-烷基、芳基-烷基、芳基-烯基、芳基或杂环烷基;或者R2和R3一起形成5、6或7成员环酰胺、环亚胺、环磺胺或环脲基团的残基;R4为较低的烷基、羟基-较低的烷基、较低的烯基、较低的环烷基、较低的环烷基-烷基或具有X-芳基、X-杂环芳基或—(CH2)1-2—CH═CR7R8的基团;X为间隔基团;R5和R6各自为氢、较低的烷基或芳基-烷基;R7和R8一起代表较低的烷基烯基,其中一个亚甲基团可选择地被杂原子取代;它们的药学上可接受的盐不仅抑制肿瘤坏死因子(TNF-α)和转化生长因子(TGF-α)从细胞中的释放,还抑制角质细胞增殖。它们可用作药物,特别用于治疗炎症、发热、出血、败血症、类风湿性关节炎、骨关节炎、多发性硬化或牛皮癣。
