showed good binding selectivity for LXRβ over LXRα. The LXRβ binding selective modulators displayed good activity for inducing ABCA1 gene expression in J774 macrophage cell line and poor efficacy in the LXRα Gal4 functional assay. 26, 37 and 41 were examined for their ability to induce SREBP-1c gene expression in Huh-7 liver cell line and they were weak partial agonists.
制备了一系列的cinnolines / quinolines,发现4-苯基-cinnoline / quinolines具有2',3'或2',5'-二取代的苄氧基部分或1-Me-7-吲哚甲氧基部分4-苯基环的间位相对于LXRα表现出对LXRβ的良好结合选择性。LXRβ结合选择性调节剂在诱导J774巨噬细胞系中诱导ABCA1基因表达方面表现出良好的活性,而在LXRαGal4功能测定中的功效较差。26,37和41检查它们诱导的Huh-7肝细胞系SREBP-1c的基因表达的能力和它们弱的部分激动剂。
