identified podocarpic acid anhydride as a 1nM agonist of LXRalpha and beta receptors. Functionally this agonist was over 8-10-fold better activator of LXR receptors compared to one of the natural ligands, 22-(R)-hydroxy cholesterol, in HEK-293 cells. An imide analog increased the level of HDL by 26%, decreased LDL by 10.6%, and increased triglyceride by 51% in hamsters. Discovery, synthesis, SAR and
肝X受体是调节胆固醇代谢的核受体。它们被氧固醇激活,导致ABCA1基因转录增加,促进胆固醇外流和HDL形成。我们已经确定了罗汉果酸酐为LXRalpha和β受体的1nM激动剂。在功能上,与HEK-293细胞中的天然配体之一22-(R)-羟基胆固醇相比,该激动剂的LXR受体活化剂高8-10倍。酰亚胺类似物使仓鼠的HDL水平提高了26%,LDL降低了10.6%,甘油三酸酯提高了51%。已经描述了发现,合成,SAR和二聚体活性的细节。
