to 24S-hydroxycholesterol (24HC). Despite a wide range of potential of CH24H as a drug target, no potent and selective inhibitors have been identified. Here, we report on the structure-based drug design (SBDD) of novel 4-arylpyridine derivatives based on the X-ray co-crystal structure of hit derivative 1b. Optimization of 4-arylpyridine derivatives led us to identify 3v ((4-benzyl-4-hydroxypiperidin-1-yl)(2
胆固醇24-羟化酶(CH24H,CYP46A1)是一种大脑特异性细胞色素P450(CYP)家族酶,通过将胆固醇转化为24S-羟基胆固醇(24HC),在脑胆固醇稳态中发挥作用。尽管 CH24H 作为药物靶点具有广泛的潜力,但尚未发现有效的选择性抑制剂。在这里,我们报告了基于hit衍生物1b的X射线共晶结构的新型4-芳基吡啶衍生物的基于结构的药物设计(SBDD)。 4-芳基吡啶衍生物的优化使我们确定3v ((4-benzyl-4-羟基哌啶-1-基)(2,4'-联吡啶-3-基)甲酮,IC 50 = 7.4 nM) 是一种高效、选择性、脑渗透性 CH24H 抑制剂。小鼠口服3v后,大脑中 24HC 水平呈剂量依赖性降低(1、3 和 10 mg/kg)。化合物3v (soticlestat,也称为 TAK-935)目前正在临床研究中,作为治疗癫痫的新型药物类别,用于治疗 Dravet 综合征和 Lennox-Gastaut
