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。
