threo-2-[alpha-hydroxy(2-naphthyl)methyl]- and 2-[alpha-hydroxy(3,4-dichlorobenzyl)]-3,3-dimethylaziridines (1d and 1c) have been prepared as conformationally restricted analogues of beta-adrenoceptor blocking agents like dichloroisoproterenol (DCI) and pronethalol. The aziridine analogues 1 except possibly 1c are competitive antagonists of isoproterenol-induced response on a guinea pig tracheal chain preparation
邻-和赤--2-(α-羟基苄基)-3,3-二甲基氮丙啶(1a和1b)和threo-2- [α-羟基(2-萘基)甲基]-和2- [α-羟基(3,已制备出β-肾上腺素受体阻断剂(如二氯异丙肾上腺素(DCI)和前萘洛尔)的构象受限类似物4-(二氯苄基)]-3,3-二甲基氮丙啶(1d和1c)。除了可能的1c以外,氮丙啶类似物1是异丙基肾上腺素诱导的豚鼠气管链制剂反应的竞争性拮抗剂,效价顺序为大于1a大于1a或大于大于1c普萘洛尔。与普萘洛尔不同,这些化合物对异丙基肾上腺素对豚鼠耳廓的反应没有影响,也没有明显的局部麻醉和抗心律失常活性。
