Novel 1-heterocyclyloxy- or 1-aryloxy-3-amidoalkylamino-2-propanol derivatives, processes for their manufacture, pharmaceutical compositions containing them and methods of using them in the treatment of heart diseases. The compounds possess .beta.-adrenergic blocking activity. Representative of the compounds disclosed is 1-(4-indolyloxy)-3-.beta.-isobutyramidoethylamino-2-propanol.
The synthesis of a series of 1-(aryloxy)-3-[[(amido)alkyl]amino] propan-2-ols where either the aryl moiety is heterocyclic or the amidic group is substituted by a heterocyclic moiety is described. Several of the compounds were more potent than propranolol when given intravenously to anesthetized rats. In contrast to previous findings with beta-blockers based on heterocyclic moieties and with either
