    氧固醇 (OHC) 是胆固醇氧化的副产物,已知可激活 Hedeghog (Hh) 信号通路。虽然在整个支架中包含羟基的 OHC 是已知的,但那些充当 Hh 信号传导激动剂的 OHC 主要在烷基侧链上包含一个羟基。我们试图通过对一系列合成 OHC 进行构效关系研究,进一步探索侧链羟基化模式如何影响氧甾醇介导的 Hh 活化。最活跃的类似物 23( R )-OHC ( 35 ) 在两个依赖于 Hh 的细胞系中证明了 Hh 信号传导的有效激活(EC 50值 0.54–0.65 μM)。此外,OHC 35与肝脏 X 受体(一种也被内源性 OHC 激活的核受体)相比,对 Hh 途径的选择性约为 3 倍。最后,35在培养的细胞中诱导成骨分化和成骨细胞形成,表明 Hh 途径的功能激动。

  • Synthesis and Evaluation of Osteogenic Oxysterols as Hedgehog Pathway Activators

    that decreases the number of steps and chromatographic purifications, and which also enhances the stereoselective nature of the synthesis. This new route also allows access to the C21 methyl group of the OHC scaffold, and several new analogues with varying stereochemistry at this location were evaluated for their ability to up‐regulate the Hh pathway.
    氧固醇(OHC)是胆固醇的代谢副产物,已知其可充当刺猬(Hh)信号传导途径的激动剂。以前,我们报道了23(S)-羟基胆固醇[23(S)-OHC,4 ]是Hh信号的有效激活剂,具有将小鼠胚胎成纤维细胞功能分化为成骨命运的能力。求23(S)-适用于体内评估的OHC,我们开发了一种经过修订的合成路线,该路线减少了步骤和色谱纯化的数量,还增强了合成的立体选择性。该新途径还允许接近OHC支架的C21甲基,并且评估了在该位置具有不同立体化学的几种新类似物上调Hh途径的能力。
  • Pharmacophore Analysis of the Nuclear Oxysterol Receptor LXRα

    A cell-free assay was developed for the orphan nuclear receptor LXR alpha that measures the ligand-dependent recruitment of a peptide from the steroid receptor coactivator 1 (SRC1) to the nuclear receptor. Using this ligand-sensing assay (LiSA), the structural requirements for activation of the receptor by oxysterols and related compounds were studied. The minimal pharmacophore for receptor activation was shown to be a sterol with a hydrogen bond acceptor at C24. 24(S),25-Epoxycholesterol (1), which meets this criterion, is among the most efficacious of the oxysterols and is an attractive candidate as the LXR alpha natural hormone. Cholenic acid dimethylamide (14) showed increased efficacy compared to 1, whereas the unnatural oxysterol 22(S)-hydroxycholesterol (4) was shown to be an antagonist of 1 in the LiSA. The structural requirements for SRC1 recruitment in the LiSA correlated with the transcriptional activity of compounds in a cell-based reporter assay employing LXR alpha -GAL4 chimeric receptors. Site-directed mutagenesis identified Trp(443) as an amino acid critical for activation of LXR alpha by oxysterol ligands. This information was combined with the structure-activity relationship developed from the LiSA to develop a 3D homology model of LXR alpha. This model may aid the design of synthetic drugs targeted at this transcriptional regulator of cholesterol homeostasis.

  • Structure–Activity Relationships for Side Chain Oxysterol Agonists of the Hedgehog Signaling Pathway

    日期:2012.10.11
    Oxysterols (OHCs) are byproducts of cholesterol oxidation that are known to activate the Hedeghog (Hh) signaling pathway. While OHCs that incorporate hydroxyl groups throughout the scaffold are known, those that act as agonists of Hh signaling primarily contain a single hydroxyl on the alkyl side chain. We sought to further explore how side chain hydroxylation patterns affect oxysterol-mediated Hh
