A series of quinoline-3-carboxamide containing sulfones was prepared and found to have good binding affinity for LXRβ and moderate binding selectivity over LXRα. The 8-Cl quinoline analog 33 with a high TPSA score, displayed 34-fold binding selectivity for LXRβ over LXRα (LXRβ IC50 = 16 nM), good activity for inducing ABCA1 gene expression in a THP macrophage cell line, desired weak potency in the
制备了一系列包含喹啉-3-甲酰胺的砜,发现它们具有对LXRβ的良好结合亲和力和对LXRα的中等结合选择性。TPSA得分高的8-Cl喹啉类似物33对LXRβ的结合选择性超过LXRα的34倍(LXRβIC 50 = 16 nM),在THP巨噬细胞系中诱导ABCA1基因表达的活性良好,所需的弱效LXRαGal4功能测定和低血脑屏障穿透力在大鼠中。
