  吡唑衍生物作为烟酸受体的部分激动剂。

  摘要：

  烟酸作为降血脂药显得独特，因为它比其他药物具有更大程度地增加HDL胆固醇水平的潜力。但是，它有一些副作用，其中严重的皮肤潮红是最常见的，并且经常限制患者的依从性。在寻找新的激动剂，用于最近鉴定和克隆的G蛋白偶联的烟酸受体中，我们合成了一系列取代的吡唑-3-羧酸，它们被证明对该受体具有显着的亲和力。通过抑制[（3）H]烟酸与大鼠脾膜的结合来测量亲和力。相对于烟酸的效能和内在活性是通过它们对[（35）S] GTPgammaS与大鼠脂肪细胞和脾膜结合的影响来确定的。有趣的是，大多数化合物是部分激动剂。特别是，证明2-重氮双环[3,3,0（4,8）]八-3,8-二烯-3-羧酸（4c）和5-丙基吡唑-3-羧酸（4f）具有K（i）值约0.15 microM的EC（50）值和约6 microM的EC（50）值，而与烟酸相比，它们的固有活性仅为约50％。活性稍强的是5-丁基吡唑-3-羧酸（4g），K（i）值为0
