de derivatives were developed as a novel class of nonsteroidal glucocorticoid receptor (GR) modulators, which are promising drug candidates for treating immune-related disorders. Focusing on the similarity of the GR and progesterone receptor (PR) ligand-binding domain (LBD) structures, we adopted our recently developed PR antagonist 10 as a lead compound and synthesized a series of derivatives. We
N-苄基-N-(4-苯氧基苯基)苯磺酰胺衍生物被开发为一类新型的非甾体类糖皮质激素受体(GR)调节剂,有望成为治疗免疫相关疾病的候选药物。着眼于GR和孕激素受体(PR)配体结合域(LBD)结构的相似性,我们采用了我们最近开发的PR拮抗剂10作为前导化合物并合成了一系列衍生物。我们发现,N-(4-苯氧基苯基)苯磺酰胺骨架可作为GR拮抗剂的多功能支架。其中,4-氰基衍生物14m最有效,IC 50GR的值为1.43μM。该化合物显示出对GR的良好选择性;它对PR保留相对较弱的拮抗活性(PR的IC 50:8.00μM;效力比10低250倍),但对AR,ERα或ERβ无活性。有趣的是,除了GR拮抗活性外,4-氨基衍生物15a还显示出对NF-κB的反式抑制活性,而14m没有。反式抑制的结构-活性关系与GR-拮抗活性的结构-活性关系不同。计算对接模拟表明15a可能以不同于14m的方式结合到GR的配体结合
