of a new class of vasodilating compounds obtained by lead structure optimization is described. Three groups of compounds were synthesized and tested for their activity on various smooth muscle preparations of the guinea pig. Beside the lead compound 3a, the most interesting derivative was 1H-imidazole-1-carbothioic acid O-cyclohexyl ester hydrochloride (5b) with a good selective vasodilating potential
在这一贡献中,描述了通过前导结构优化获得的新型血管扩张化合物的开发。合成了三组化合物,并测试了它们对豚鼠各种平滑肌制剂的活性。除铅化合物3a以外,最有趣的衍生物是1 H-咪唑-1-硫代甲酸O-环己基酯盐酸盐(5b),对主动脉和肺动脉环具有良好的选择性血管舒张潜力(EC 50分别为14μM和24μM)。由于小分子的特性,化合物的水解行为可以很容易地适应,因此就药剂作用的持续时间开辟了一条新途径。借助结构-活性关系研究,提出了影响合成化合物离体平滑肌细胞制剂生物学活性的结构基序。所提出的化合物为确定有希望的分子作为心肌梗死的紧急治疗方法提供了很好的工具。
