  A general para‐selective C‐H functionalization was achieved via a steric control strategy. Para‐iodo, bromo, chloro, nitro, and trifluormethyl aniline derivatives were prepared via in situ generated, bulky hypervalent iodinium reagents in as little as 10 min. Products can be purified without column chromatography or recrystallization, which significantly reduces the waste and simplifies the work‐up

• Structure–activity relationship study of non-steroidal NPC1L1 ligands identified through cell-based assay using pharmacological chaperone effect as a readout

  日期：2014.7

  We previously discovered steroidal NPC1L1 ligands by using a novel cell-based assay that employs pharmacological chaperone effect as a readout. Those steroid derivatives bound to a site different from both the sterol-binding domain and the ezetimibe-binding site, implying that they may be a novel class of NPC1L1 inhibitors with a distinct mode of action. As an extension of that work, we aimed here

  Niemann-Pick C1样1（NPC1L1）是一种肠道胆固醇转运蛋白，已知是胆固醇吸收抑制剂依泽替米贝的靶标。我们以前通过使用一种新的基于细胞的测定法发现了甾体NPC1L1配体，该测定法采用药理分子伴侣效应作为读数。这些类固醇衍生物与不同于固醇结合域和依泽麦布结合位点的位点结合，这意味着它们可能是一类具有独特作用方式的新型NPC1L1抑制剂。作为这项工作的延伸，我们的目标是通过使用相同的分析方法筛选聚焦于肝X受体（LXR）的配体库，从而找到非甾体NPC1L1配体，这些配体可能比甾体配体更适合临床应用。将氧固醇识别为内源性配体的核受体。
