Abstract

New 1-phenyl-2-aminocarbonylindole compounds are described which have the general formula I ##STR1## where R.sub.1 is a hydrogen atom, or a lower alkyl, alkenyl, cycloalkylalkyl radical, R.sub.2 is a hydrogen atom or a lower alkyl radical, R.sub.3 is a hydrogen or halogen atom, or a lower alkyl, hydroxyl or lower alkoxy radical, R.sub.4 is a hydrogen or halogen atom, or a lower alkyl, hydroxyl or lower alkoxy radical, or, if R.sub.3 is a hydrogen atom, R.sub.4 may be a nitro or trifluoromethyl radical, or R.sub.3 and R.sub.4 together denote a methylenedioxy or ethylenedioxy radical, R.sub.5 has the meanings given for R.sub.3, R.sub.6 has the meanings given for R.sub.4, R.sub.7 is a hydrogen atom or, if R.sub.5 and R.sub.6 are lower alkoxy radicals, R.sub.7 may also be a lower alkoxy radical, R.sub.8 and R.sub.9 are each a hydrogen atom or a lower alkyl radical or, together with the nitrogen atom, form a heterocyclic group, and Z is an alkylene chain which is optionally substituted by hydroxyl. The compounds have pharmaceutical properties, in particular antiarrhythmic properties. The compounds may be in the form of the free bases or acid addition salts. Pharmaceutical compositions c…
