ABSTRACT Pyrrolobenzimidazoles of the general formula: Image (I) wherein R1 is a hydrogen atom or an alkyl, alkenyl or cycloalkyl radical; R2 is a hydrogen atom, cyano group or alkyl or alkenyl radical or a carbonyl group substituted by hydroxyl, alkyl, alkoxy, amino, alkyl- amino, dialkylamino or hydrazino or together with R1 forms a cycloalkylene radical or R1 and R2 together form an alkylidene or cycloalkylidene radical; R3, R4 and R5, which can be the same or different, each represent a hydrogen atom or an alkanesulphonyloxy, trifluoromethanesulphonyloxy, alkanesulphonylamino, trifluoromethanesulphonylamino, N-alkyl-alkane- sulphonylamino, N-alkyl-trifluoromethanesulphonyl- amino, alkylsulphenylmethyl, alkylsulphinylmethyl or alkylsulphonylmethyl radical, a carbonyl group sub- stituted by hydroxyl, alkoxy, amino, alkylamino or dialkylamino, a sulphonyl group substituted by amino, alkylamino, dialkylamino or cyclic imino, whereby a methylene group in the 4-position can be replaced by a sulphur or oxygen atom, an alkylcarbonylamino, amino- carbonylamino or alkylaminocarbonylamino radical, an alkylthio, alkylsulphinyl or alkylsulphonyl radical, a nitro, halogen, amino, hydroxyl, alkyl, trifluoro- methyl, alkoxy, alkenyloxy, alkynyloxy, cyanoalkoxy, carboxyalkoxy, alkoxycarbonylalkoxy, dialkylamino, 1-imidazolyl or cyano group; X is a valency bond, a C1-C4 alkylene radical or a vinyl radical; and T is an oxygen or sulphur atom; the tautomers thereof and the physiologically acceptable salts thereof with inorganic or organic acids, are useful for the pro- phylaxis and treatment of heart and circulatory diseases.
