A novel series of N-(4-aryl-5-aryloxy-thiazol-2-yl)-amides as RORγt inverse agonists was discovered. Binding mode analysis of a RORγt partial agonist (2c) revealed by co-crystal structure in RORγt LBD suggests that the inverse agonists do not directly interfere with the interaction between H12 and the RORγt LBD. Detailed SAR exploration led to identification of potent RORγt inverse agonists such as
发现了一系列新颖的N-(4-芳基-5-芳氧基-噻唑-2-基)-酰胺作为RORγt反向激动剂。RORγtLBD中共晶体结构揭示的RORγt部分激动剂(2c)的结合模式分析表明,反向激动剂不会直接干扰H12与RORγtLBD之间的相互作用。详细的SAR探索导致鉴定出有效的RORγt反向激动剂,例如3m,pIC 50为8.0。该系列中的选定化合物在Th17细胞分化试验中显示出合理的活性,并且在小鼠肝微粒体中的固有清除率较低。
