Ultra-short-acting .beta.-adrenergic receptor blocking agents. 3. Ethylenediamine derivatives of (aryloxy)propanolamines having esters on the aryl function
摘要:
Various ethylenediamine derivatives have been incorporated into the nitrogen substituent of certain short-acting (aryloxy)propanolamine systems that contain esters on their aryl functions. Although several of these compounds showed durations of action comparable to their prototypes, most of the nitrogen substituents significantly prolonged the duration of beta-adrenergic blockade. Similarly, while one of the compounds showed appreciable cardioselectivity in vitro, generally, little enhancement of cardioselectivity was obtained. A brief discussion of structure-activity relationships observed for the ethylenediamine derivatives is presented.
The synthesis of a series of 1-phenoxy-3-[[(substituted-amido)alkyl]amino]-2-propanols is described. Many of the compounds are more potent than propanolol as beta blockers, while having cardioselectivity comparable to that of practolol, when given intravenously to anesthetized cats. The structure-activity relationships shown by this series of compounds provide further evidence that the addition of substituents to the alkylamino moeity of a beta blocker can confer cardioselectivity and that amidic substituents are remarkably effective.
