A series of novel pyrazole carboxylic acid derivatives was designed and synthesized, and their antagonism effect on endothelin (ET)-1-induced contraction in the rat thoracic aortic ring was screened. The radio receptor assay was used to examine the potency of the compounds on ET receptor. Some target compounds demonstrated significant inhibitory activity, especially 7m, which showed a potent inhibition
设计并合成了一系列新型的吡唑羧酸衍生物,并筛选了它们对内皮素(ET)-1诱导的大鼠胸主动脉环收缩的拮抗作用。放射受体测定法用于检查化合物对ET受体的效力。一些目标化合物表现出显着的抑制活性,尤其是7m,它显示出比对比化合物BQ123高的有效抑制百分比。进一步的对ET的结合和选择性分析表明,7m在纳摩尔水平上对ETA有很强的结合活性,ET A / ET B的比例为36。因此,我们推断7m是ET的非选择性拮抗剂。A和ET B 具有在心血管疾病中进一步发展的潜力。
