SULPHUR- AND OXYGEN-CONTAINING DIARYL COMPOUNDS

摘要

The sulphur- and oxygen-containing diaryl compounds of the formula: I in which A is O, S, SO or SO2, B is O or, when A is O, S, Alk is a C1-C4 hydrocarbon radical with a straight or branched chain, R represents COOH, an esterified COOH group, a carboxylic amide group, OH, O-SO2CH3, NH2, NHR1, NR1R2, NHZOH, NHZNR1R2, C(=NH)NH2, C(=NH)NHOH or 2-.DELTA.2-imida?olinyl, z is a C2-C4 hydrocarbon radical with a straight or branched chain, and R1 and R2 each represent a C1-C3 lower alkyl group, and their addition salts with bases when R is COOH, and their addition salts with acids when R is a basic radical, are useful pharmacological agents in the treatment of circulatory complaints such as cardio-vascular illnesses.
