Retinoic acid receptor-related orphan receptor γ (RORγ), a member of the nuclear hormone receptor superfamily, is a promising therapeutic target for treating Th17-mediated autoimmune diseases. We performed structure-based virtual screening targeting the RORγ ligand-binding domain. Among the tested compounds, s4 demonstrated RORγ antagonistic activities with micromolar IC50 values in both an AlphaScreen
视黄酸受体相关的孤儿受体γ(RORγ)是核激素受体超家族的成员,是治疗Th17介导的自身免疫性疾病的有希望的治疗靶标。我们进行了针对RORγ配体结合域的基于结构的虚拟筛选。在测试的化合物中,s4在AlphaScreen测定(20.27μM)和基于细胞的报告基因测定(11.84μM)中均表现出具有微摩尔IC 50值的RORγ拮抗活性。s4化合物的优化导致化合物7j,8c,8k和8p的鉴定,所有这些均显示出IC 50显着增强的RORγ抑制作用值为40–140 nM。这些结果代表了开发有效的小分子RORγ抑制剂的有希望的起点。
