Phenothiazine derivatives of formula: ##STR1## in which Y is hydrogen or halogen, R.sub.1 and R.sub.2, which may be identical or different, denote alkyl, cycloalkyl-alkyl, hydroxyalkyl or acetyloxyalkyl radicals or form, together with the nitrogen atom to which they are attached, an optionally substituted, saturated or partially unsaturated 4- to 7-membered heterocycle; and either X is oxygen, sulphur or: N-R.sub.4, R is cycloalkyl, phenyl or --CH.sub.2 R.sub.3, R.sub.3 is H, alkyl (1 to 5 C), alkenyl or alkynyl (2 to 4 C), cycloalkyl (3 to 6 C), phenyl, substituted phenyl or a heterocyclic radical, R.sub.4 is H or --CN, except that X is not oxygen if, simultaneously, R.sub.3 is H or alkyl, R.sub.1 and R.sub.2 are alkyl or NR.sub.1 R.sub.2 forms an unsubstituted heterocycle, and Y is H; or X is: N-R.sub.4 and R.sub.4 forms, with R and the neighbouring atoms, an optionally substituted imidazolyl or imidazolinyl radical or a hexahydrobenzimidazolyl radical, in their isomeric forms and mixtures thereof and their acid addition salts are useful as analgesics and diuretics.
公式为:##STR1## 其中 Y 为氢或卤素,R.sub.1 和 R.sub.2 可相同也可不同,表示烷基、环烷基-烷基、羟基烷基或乙酰氧基烷基基团,或者与它们连接的氮原子一起形成一个可选取代的饱和或部分不饱和的4-至7-成员杂环;而 X 为氧、硫或:N-R.sub.4,R 为环烷基、苯基或 --CH.sub.2 R.sub.3,R.sub.3 为 H、烷基(1 到 5 C)、烯基或炔基(2 到 4 C)、环烷基(3 到 6 C)、苯基、取代苯基或杂环基,R.sub.4 为 H 或 --CN,但若同时 R.sub.3 为 H 或烷基、R.sub.1 和 R.sub.2 为烷基或 NR.sub.1 R.sub.2 形成未取代的杂环,且 Y 为 H,则 X 不为氧;或 X 为:N-R.sub.4,且 R.sub.4 与 R 及相邻原子形成可选取代的咪唑基或咪唑啉基基团或环己氢苯并咪唑基团,以其异构体形式和混合物及其酸盐形式作为镇痛剂和利尿剂。
