title: Beta-adrenergic blocking agents. 19. 1-Phenyl-2-[[(substituted-amido)alkyl]amino]ethanols.
abstract: The synthesis of a 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 blocking agents.
