We have prepared a series of piperazinylpyridine derivatives for the treatment of irritable bowel syndrome (IBS). These compounds, which were designed by pharmacophore analysis, bind to both serotonin subtype 1A (5-HT1A) and subtype 3 (5-HT3) receptors. The nitrogen atom of the isoquinoline, a methoxy group and piperazine were essential to the pharmacophore for binding to these receptors. We also synthesized furo- and thienopyridine derivatives according to structure–activity relationship analyses. Compound 17c (TZB-20810) had high affinities to these receptors and exhibited 5-HT1A agonistic activity and 5-HT3 antagonistic activity concurrently, and is a promising drug for further development in the treatment of IBS.
我们已准备了一系列哌嗪吡啶衍生物用于治疗肠易激综合征(IBS)。这些化合物通过药效团分析设计,能够同时与血清素亚型1A(5-HT1A)和亚型3(5-HT3)受体结合。异喹啉的氮原子、一个甲氧基和哌嗪是与这些受体结合的药效团的重要组成部分。我们还根据结构-活性关系分析合成了呋喃和噻吡啶衍生物。化合物17c(TZB-20810)对这些受体具有很高的亲和力,同时展现出5-HT1A激动剂活性和5-HT3拮抗剂活性,是治疗IBS方面具有进一步开发潜力的有前景药物。
