Novel 1-aryl-2-amidoalkylaminoethanol 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-phenyl-2-(1,1-dimethyl-2-phenylacetamidoethyl)amino-ethanol.
series of derivatives of 1-phenyl-2-[[(substituted amido)alkyl]amino]ethanols is described. The compounds were investigated for beta-adrenoceptor blocking properties, and many showed a surprising degree of potency and beta 1-cardioselectivity when tested in vivo in anesthetized cats. The structure-activity relationships shown by this series of compounds are discussed and related to known beta-adrenergic
