A series of nitric oxide-donating derivatives of [1,2,4]triazol-5(4H)-one (9a-f and 15a-f) as a novel class of angiotensin II receptor AT1 antagonists have been designed and synthesized by coupling furoxan and nitric oxide with lead compound 1. The synthesized compounds were evaluated for their antagonism of AT1 receptor with induced contraction in the rabbit thoracic aortic ring and the results showed that compounds 9b, 15b and 15d exhibited potent antagonistic activity of AT1 receptor. Moreover 9b, 15b, 15d, 15e had good maximum NO release amount of this series.
一系列新型血管紧张素II受体AT1拮抗剂——[1,2,4]三唑-5(4H)-酮(9a-f和15a-f)的硝酸氧化物衍生物,通过将呋喃并氧和硝酸氧化物与前导化合物1结合而设计并合成。合成的化合物在兔胸主动脉环中诱导收缩的情况下,对其AT1受体的拮抗作用进行了评估,结果显示化合物9b、15b和15d展现出强大的AT1受体拮抗活性。此外,9b、15b、15d、15e在这一系列化合物中具有良好的最大NO释放量。
