2-propanol spacer to N-substituted piperazine residue were synthesized. All the new compounds were screened for their effect on β-adrenergic blocking activity on the norepinephrine-induced precontracted aortic ring module. Most test compounds displayed appreciable β-adrenolytic activity compared to propranolol as a reference standard. The results have shown that compounds 3a, 3d, 3e and 7c displayed appreciable
摘要合成了新型的4-(4-溴苯基)酞嗪和酞嗪酮衍生物,它们通过2-丙醇间隔基连接到N-取代的哌嗪残基上。筛选了所有新化合物对去甲肾上腺素诱导的预收缩主动脉环组件对β-肾上腺素阻断活性的影响。与普萘洛尔作为参考标准品相比,大多数测试化合物均表现出明显的β-肾上腺素分解活性。结果表明,化合物3a,3d,3e和7c显示出明显的抑制去甲肾上腺素引起的主动脉环收缩的作用。 图形概要合成了一种新型的4-(4-溴苯基)酞嗪和酞嗪酮衍生物,该衍生物通过2-丙醇间隔基连接到N-取代的哌嗪残基上。筛选所有新化合物对去甲肾上腺素诱导的预收缩主动脉环组件对β-肾上腺素阻断活性的影响。
