Pharmacologically-active aminopyrrole derivatives of the formula <IMAGE> wherein: R is selected from hydrogen, (C1-4)alkyl, benzyl and chlorobenzyl; R1 is selected from hydrogen, (C1-4)alkyl, phenyl and phenyl substituted by a radical selected from methyl, ethyl, methoxy, ethoxy, benzyloxy, fluoro, chloro and bromo; R2 and R3 individually represent hydrogen or (C1-4)alkyl or, taken together, represent an isopropylidene, a benzylidene or a chlorobenzylidene radical; R4 is selected from (C2-4)alkanoyl; carbo(C1-3)alkoxy; benzoyl, benzoyl substituted by a radical selected from chloro, methoxy or ethoxy; carbamoyl, methylcarbamoyl and phenyl carbamoyl; R5 is selected from hydrogen, (C1-4)alkyl, carbo(C1-3)alkoxy, carbomethoxymethyl, carbethoxymethyl, trifluoromethyl and carbamoyl, with the proviso that when R is hydrogen, R1 and R5 are methyl and R4 is carbethoxy, R2 and R3 cannot simultaneously represent hydrogen; and a salt thereof with a pharmaceutically-acceptable acid. The compounds have anti-inflammatory and CNS-depressant utility. They are also useful as analgesics and antipyretics and display a very low degree of anti-ulcerogenic activity.
