A series of 3-quinolylurea derivatives (1) was synthesized and evaluated for acyl-CoA:cholesterol acyltransferase (ACAT) inhibitory activity. For in vitro studies, the most potent inhibitory activity was found in derivatives having substituents at the 6,7- or 6,8-positions and an ortho-substituted phenyl group at the 4-position of quinoline ring. The 2,4-difluorophenyl group appeared to be the optimum
合成了一系列3-喹啉脲衍生物(1),并评估了其酰基辅酶A:胆固醇酰基转移酶(ACAT)的抑制活性。对于体外研究,发现最有效的抑制活性是在喹啉环的6,7或6,8-位具有取代基和邻位取代的苯基的衍生物中。2,4-二氟苯基似乎是脲部分的最佳N'-取代基。化合物52-54和59的IC50值为纳摩尔级。在以胆固醇喂养的大鼠中,观察到化合物50、52和54的血浆胆固醇降低活性低于1 mg / kg / day。在饮食中不加胆固醇的仓鼠中,化合物52的胆固醇水平也较低。
