profile and showed in vivo efficacy. Compounds OX03050 and OX03771 were found to inhibit squalene synthase, the first committed step in cholesterol biosynthesis. These squalene synthase inhibitors were shown to act cooperatively with statins to increase LDLR expression in vitro. Overall, we demonstrated here a novel series of small molecules with the potential to be further developed to treat patients
高胆固醇血症仍然是心血管疾病发展的主要危险因素之一。许多大型双盲研究表明,使用他汀类药物降低低密度脂蛋白(LDL)胆固醇可将发生心血管事件的风险降低约30%。然而,尽管他汀类药物获得了成功,但由于依从性或效力问题,一些患者人群仍无法降低其LDL胆固醇以满足目标脂质水平。对于患有杂合性家族性高胆固醇血症的患者尤其如此,他们可能需要额外上调低密度脂蛋白受体(LDLR)才能将LDL胆固醇水平降低到最大剂量他汀类药物可达到的水平。在这里,我们从基因组DNA报告分子筛选中鉴定出一系列小分子,它们以纳摩尔效价(EC50 = 39 nM)上调了小鼠和人肝细胞系中的LDLR。对铅化合物OX03771 [(E)-N,N-二甲基-3-(4-苯乙烯基苯氧基)丙-1-胺]进行的构效关系研究导致鉴定了化合物OX03050 [(E)- 3-(4-苯乙烯基苯氧基)丙-1-醇],具有相似的效价(EC50 = 26 nM)
