The nuclear constitutive androstane receptor (CAR, NR1I3) plays significant roles in many hepatic functions, such as fatty acid oxidation, biotransformation, liver regeneration, as well as clearance of steroid hormones, cholesterol, and bilirubin. CAR has been proposed as a hypothetical target receptor for metabolic or liver disease therapy. Currently known prototype high-affinity human CAR agonists
核组成型雄烷受体 (CAR, NR1I3) 在许多肝功能中起着重要作用,例如脂肪酸氧化、生物转化、肝再生以及类固醇激素、胆固醇和胆红素的清除。CAR 已被提议作为代谢或肝病治疗的假设目标受体。目前已知的原型高亲和力人CAR激动剂如CITCO(6-(4-chlorophenyl)imidazo[2,1- b ][1,3]thiazole-5-carbaldehyde- O- (3,4-dichlorobenzyl)oxime)具有有限的选择性,激活孕烷 X 受体 (PXR) 受体,NR1I 亚家族的相关受体。我们发现了 3-(1 H -1,2,3-triazol-4-yl)imidazo[1,2- a的几种衍生物]在纳摩尔浓度下直接激活人类 CAR 的吡啶。虽然化合物39在人源化 CAR 小鼠和人类肝细胞中调节 CAR 靶基因,但它不会激活其他核受体,并且在细胞和遗传毒性测定以及啮齿动物毒性
