ABSTRACT:
Compounds are prepared of the formula: ##SPC1##
Wherein A is a straight or branched chain alkylene or alkylidene radical having 2 to 5 carbon atoms and which is substituted by an alkylthio group having 1 to 4 carbon atoms, a carboxymethyl thio group, a carboxyethyl thio group, an alkylsulfonyl group having 1 to 4 carbon atoms, a mercapto group, or the substituent on A together with --COR.sub.4 forms a 4 to 7 membered thiolactone ring, or A is substituted by an acylmercapto group wherein the acyl is benzoyl, a benzoyl radical substituted with one, two or three alkoxy groups with 1 to 6 carbon atoms, an alkanoyl radical of 1 to 6 carbon atoms, an alkenoyl radical of 3 to 6 carbon atoms, R.sub.1, R.sub.2 and R.sub.3 are the same or different and are alkyl groups of 1 to 5 carbon atoms and one of R.sub.1, R.sub.2 and R.sub.3 also can be hydrogen or the acyl radical of an alkanoic acid of 2 to 4 carbon atoms and R.sub.4 is a hydroxy group or an alkoxy group with 1 to 5 carbon atoms and their pharmacologically acceptable salts. The compounds are pharmacodynamically active and are suited for prophylaxis and treatment of heart illnesses such as cardiac ischemia, cardiac infarct, heart rhythm and circulatory disturbances.
