A series of binary (aryloxy)propanolamines has been prepared and examined in vitro and in vivo for beta-adrenoreceptor blocking activity. These symmetrical compounds consist of two (S)-(phenyloxy)propanolamine pharmacophores coupled through alkylenedioxy or poly(oxyethylenedioxy) linking units of varying lengths. Examples of such binary compounds linked through the 2,2', 3,3', and 4,4' positions in
已经制备了一系列二元(芳氧基)丙醇胺,并在体内和体外检查了β-肾上腺素受体阻断活性。这些对称化合物由两个(S)-(苯氧基)丙醇胺药效基团组成,它们通过不同长度的亚烷基二氧基或聚(氧乙烯二氧基)连接单元偶联。已经制备了通过药效基团的芳环中的2,2',3,3'和4,4'位置连接的这种二元化合物的实例。体外和体内试验数据表明,2,2'化合物倾向于是选择性的β2-肾上腺素能阻断剂,4,4'二元化合物倾向于是选择性的β-1肾上腺素阻断剂,而那些具有3,3'的化合物连接表现出中间选择性。4,4'-连接的二元化合物之一4s在体内表现出有效的心脏选择性β受体阻滞作用,
