Novel 3,6-disubstituted pyridazines were synthesized by facile method and screened for their vasorelaxant properties utilizing isolated thoracic rat aortic rings. Compounds 8a and 11a exerted potent vasorelaxant activity (IC50 = 198 and 177 μM, respectively) relative to doxazosin mesylate (used reference standard, IC50 = 226 μM), that, they may represent promising hits for treatment of cardiovascular
通过简便的方法合成了新颖的3,6-二取代的哒嗪,并使用分离的大鼠胸主动脉环筛选了它们的血管舒张特性。 相对于甲磺酸多沙唑嗪(使用的参考标准,IC 50 = 226μM),化合物8a和11a发挥了强大的血管舒张活性(分别为IC 50 = 198和177μM),它们可能代表了治疗心血管疾病的有希望的药物。观察到的活性通过具有统计学意义的QSAR模型验证(N = 32,n = 6,R 2 = 0.811782,R 2 cvOO = 0.7153,R 2 cvMO = 0.7209,F = 17.9708,s 2 = 9.65226×10 -8)是使用CODESSA-Pro软件获得的。
