Claim:
A compound of formula (I): its physiologically acceptable salts or, wherein: R 1 is selected from an optionally substituted group consisting of carbocyclic aryl-(CH 2 ) x —, biaryl-(CH 2 ) x — and cycloalkyl-(CH 2 ) x —; T is O or S; R 2 and R 3 are independently selected from hydrogen or from an optionally substituted group consisting of C 1-4 alkyl and cycloalkyl; A is selected from formula (c-1) or (c-2): wherein R 4 is hydrogen and R 5 is selected from the group consisting of hydrogen, halo, hydroxy, thiol and cyano or from an optionally substituted group consisting of C 1-12 alkyl, carbocyclic aryl-(CH 2 ) x —, biaryl-(CH 2 ) x —, and cycloalkyl-(CH 2 ) x —; x is 0, 1, 2, 3 or 4; and wherein one or more hydrogens of the —(CH 2 ) x group may be replaced by a group selected from hydroxy, halo, cyano, alkoxy, thiol and alkylthio or from an optionally substituted group consisting of alkyl and amino; and pharmaceutically acceptable salts thereof with the provisio that the following compounds are excluded: 2-Cyanamino-6,7-dihydro-7,7-dimethyl-3H,5H-pyrrolo(2,3-f)benzimidazol-6-one; 2-Cyanamino-5,7,7-trimethyl-6,7-dihydro-3H-pyrrolo(2,3-f)benzimidazol-6-one; and 2-Cyanamino-6,7-dihydro-7,7-cyclopropyl-3H,5H-pyrrolo(2,3-f)benzimidazol-6-one.
