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可以相同也可以不同,表示烷基,环烷基-烷基,羟基烷基或醋氧基烷基基团,或者与它们所连接的氮原子一起形成一个可选的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至5个碳)、烯基或炔基(2至4个碳)、环烷基(3至6个碳)、苯基、取代苯基或杂环基,R.sub.4为H或--CN,但如果同时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,则X不为氧,Y为H;或X为:N-R.sub.4,R.sub.4与R和相邻原子一起形成可选的取代咪唑基或咪唑啉基基团或六氢苯并咪唑基基团,它们的异构体和混合物及其酸加合物可用作镇痛剂和利尿剂。
