a uniquely substituted phenyl sulfone into a series of biphenyl imidazole liver X receptor (LXR) agonists afforded a dramatic potency improvement for induction of ATP binding cassette transporters, ABCA1 and ABCG1, in human whole blood. The agonist series demonstrated robust LXRβ activity (>70%) with low partial LXRα agonist activity (<25%) in cell assays, providing a window between desired blood cell
将独特取代的苯砜引入一系列联苯咪唑肝脏X受体(LXR)激动剂中,可显着提高人类全血中ATP结合盒转运蛋白ABCA1和ABCG1的诱导效力。激动剂系列在细胞试验中显示出强大的LXRβ活性(> 70%)和低的部分LXRα激动剂活性(<25%),为食蟹猴中所需的血细胞ABCG1基因诱导与作为激动剂15的甘油三酸酯适度升高之间提供了窗口。在苯砜中增加极性也降低了与血浆蛋白(人α-1-酸糖蛋白)的结合。基于激动剂的体外结合,选择激动剂15进行临床开发 特性,优异的药代动力学参数和良好的脂质谱。
