.beta.-Adrenoceptor stimulant properties of amidoalkylamino-substituted 1-aryl-2-ethanols and 1-(aryloxy)-2-propanols
摘要:
Parallel series of 2-[(2-amidoethyl)amino]-1-arylethanols and 1-[(2-amidoethyl)amino]-3-(aryloxy)-2-propanols have been prepared, and the compounds were tested as beta-adrenoceptor stimulants on the heart and circulation of the dog. The corresponding 2-(alkylamino)-1-arylethanols and 3-(alkylamino)-2-propanols have been tested for comparison and the structure-activity relationships (SAR) examined. The arylethanols are potent full agonists, showing selectivity for the heart relative to blood vessels, while the (aryloxy)propanols are even more cardioselective and are partial agonists. Within a narrow series of 1-[(amidoethyl)amino]-3-(4-hydroxyphenoxy)-2-propanols, careful examination of the SAR of the amide group showed that great variation in cardioselectivity and degree of agonism may be produce. From this study ICI 118587, N-[20[[2-hydroxy-3-(4-hydroxyphenoxy)propyl]amino]ethyl]-4-morpholinecarboxamide, was selected for its high cardioselectivity and 50% agonist properties. This compound in under clinical evaluation as a cardiac stimulant.

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

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
