The present invention provides indole derivatives of the general formula: ##STR1## wherein R.sub.1 is a hydrogen atom or an alkyl, alkenyl, cycloalkyl, cycloalkenyl, carboxyl, cyano, alkylcarbonyl, alkoxycarbonyl, aminocarbonyl, alkylaminocarbonyl, dialkylaminocarbonyl or aryl radical, R.sub.2 is a hydrogen atom or an alkyl, trihalogenomethyl, hydroxyl, cycloalkyl, cyano, carboxyl, alkoxycarbonyl, alkylcarbonyl, aminocarbonyl, alkylaminocarbonyl or dialkylaminocarbonyl radical; R.sub.2 is a heterocyclic five-membered ring containing 1 to 4 heteroatoms or a heterocyclic six-membered ring containing 1 to 5 heteroatoms, the heteroatoms of the five- and six-membered rings being the same or different and being nitrogen, oxygen or sulphur and one or more of the nitrogen atoms optionally carrying an oxygen atom, the said five- and six-membered rings optionally being substituted by one or more alkyl, alkoxy, alkylthio, oxo, hydroxyl, nitro, amino, halogen or cyano groups; or R.sub.2 is ##STR2## the tautomers thereof and the physiologically acceptable salts thereof with inorganic and organic acids. The present invention also provides processes for the preparation of these compounds and pharmaceutical compositions containing them. Furthermore, the present invention provides intermediates of the general formula: ##STR3## in which R.sub.1, R.sub.2, A and X have the same meanings as above, and processes for the preparation of these intermediates.
本发明提供了一般式为:##STR1##的吲哚衍生物,其中R.sub.1是氢原子或烷基、烯基、环烷基、环烯基、羧基、氰基、烷基羰基、烷氧羰基、氨基羰基、烷基氨基羰基、双烷基氨基羰基或芳基基团,R.sub.2是氢原子或烷基、三卤甲基、羟基、环烷基、氰基、羧基、烷氧羰基、烷基羰基、氨基羰基、烷基氨基羰基或双烷基氨基羰基基团;R.sub.2是含有1至4个杂原子的杂环五元环或含有1至5个杂原子的杂环六元环,五元环和六元环的杂原子相同或不同,可以是氮、氧或硫,其中一个或多个氮原子可选地携带一个氧原子,这些五元环和六元环可选地被一个或多个烷基、烷氧基、烷基硫基、氧代、羟基、硝基、氨基、卤素或氰基基团取代;或R.sub.2是##STR2##及其互变异构体和与无机和有机酸形成的生理上可接受的盐。本发明还提供了制备这些化合物的方法和含有它们的药物组合物。此外,本发明提供了一般式为:##STR3##的中间体,其中R.sub.1、R.sub.2、A和X的含义与上述相同,并提供了制备这些中间体的方法。
