Novel derivatives of 4-amino-6,7-dimethoxyquinoline are disclosed as regulators of the cardiovascular system, in particular as antihypertensive agents, which have the formula:
where R is a dialkylamine piperidino or 6,7-dimethoxy--1,2,3,4-tetrahvdroisoqumoi-2-yl- group, or a piperazino group optionally substitutea in the 4-position by an alkyl, aryl, aromatic heterocyclic. acyt N-substituted carbamoyl or esterified carboxyl group. Preparation of such compounds by cyclisation of N-(1R-subsntuted-ethylidene)-2-cyano-4,5-dimeth- oxy-amilines and by appropnate treatment of the compound in which R is an dnsupstituted piperazmo group, is described.
