The new pyrrolobenzimidazoles according to the present invention are compounds of the general formula: ##STR1## wherein R.sub.1 is a hydrogen atom or an alkyl, alkenyl or cycloalkyl radical, R.sub.2 is a hydrogen atom, an alkyl or alkenyl radical or a cyano group or a carbonyl group substituted by a hydroxyl or hydrazino group or by an alkyl, alkoxy, amino, alkylamino or dialkylamino group or together with R.sub.1 represents a cycloalkylene radical or R.sub.1 and R.sub.2 together form an alkylidene or cycloalkylidene radical, X is a valency bond, a C.sub.1 -C.sub.4 alkylene radical or a vinylene radical, T is an oxygen or sulphur atom and Py is a 2-, 3- or 4-pyridyl radical which optionally carries an oxygen atom on the ring heteroatom and/or can be substituted one or more times by alkyl, alkoxy, hydroxyl, cyano or nitro, as well as by halogen; the tautomers thereof and the physiologically acceptable salts thereof with inorganic and organic acids.
根据本发明,新的吡咯并苯并咪唑化合物的一般式为:##STR1## 其中R.sub.1是氢原子或烷基、烯基或环烷基基团,R.sub.2是氢原子、烷基或烯基基团或氰基或羟基或肼基或烷基、烷氧基、氨基、烷基氨基或二烷基氨基基团取代的羰基基团,或与R.sub.1一起代表环烷基基团,或R.sub.1和R.sub.2一起形成烷基亚甲基或环烷基亚甲基基团,X是一个价键,C.sub.1-C.sub.4烷基基团或乙烯基基团,T是氧原子或硫原子,Py是2-、3-或4-吡啶基基团,该基团在环杂原子上可以携带一个氧原子和/或可以被烷基、烷氧基、羟基、氰基或硝基以及卤素一次或多次取代;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。
