title: Flavones. 1. Synthesis and antihypertensive activity of (3-phenylflavonoxy)propanolamines without beta-adrenoceptor antagonism.
abstract: The synthesis of a series of (3-phenylflavonoxy)propanolamines is described. These compounds were evaluated for potential antihypertensive activity in spontaneously hypertensive rats, as well as for in vivo and in vitro evidence of beta-adrenoceptor antagonism. Some of the compounds of this series exhibited effective antihypertensive properties but did not antagonize beta-adrenergic receptors. These active compounds represent a unique series of effective antihypertensive agents that, despite possessing structural characteristics typical of beta-blockers, does not have beta-adrenergic receptor blocking activity.
