• Studies on Hypolipidemic Agents. II. Synthesis and Pharmacological Properties of Alkylpyrazole Derivatives

  A series of 5-alkylpyrazole derivatives was synthesized and evaluated for potent hypolipidemic activity in rats. Many pyrazole derivatives with an alkyl group at the 5 position of the pyrazole ring were found to possess high hypolipidemic activity. Homologation of the alkyl chain led to marked increase in activity, but introduction of other substituents at other sites on the pyrazole ring failed to

  合成了一系列的5-烷基吡唑衍生物，并对其在大鼠中的有效降血脂活性进行了评估。发现许多在吡唑环的5位具有烷基的吡唑衍生物具有高降血脂活性。烷基链的同源性导致活性显着增加，但是在吡唑环上其他位点引入其他取代基未能增强活性。另外，用异恶唑环取代吡唑环导致活性显着降低。在测试的化合物中，5-n-十三烷基吡唑-3-羧酸（5k）表现出最有利的活性谱，并且与氯贝特一样有效。该化合物5k在急性试验（LD50 = 10.0g / kg）中显示出相当低的毒性，因此目前正在接受进一步的药理评估。

  acid (4f) proved active with K(i) values of approximately 0.15 microM and EC(50) values of approximately 6 microM, while their intrinsic activity was only approximately 50% when compared to nicotinic acid. Even slightly more active was 5-butylpyrazole-3-carboxylic acid (4g) with a K(i) value of 0.072 microM, an EC(50) value of 4.12 microM, and a relative intrinsic activity of 75%.

  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
