factor RORγt is an attractive drug-target due to its role in the differentiation of IL-17 producing Th17 cells that play a critical role in the etiopathology of several autoimmune diseases. Identification of starting points for RORγt inverse agonists with good properties has been a challenge. We report the identification of a fragment hit and its conversion into a potent inverse agonist through fragment
转录因子RORγt由于其在产生IL-17的Th17细胞分化中的作用而成为有吸引力的药物靶标,而Th17细胞在几种自身免疫性疾病的病因病理中起关键作用。鉴定具有良好性能的RORγt反向激动剂的起点一直是一个挑战。我们报告了片段命中的鉴定,并通过片段优化,增长和合并努力将其转化为有效的反向激动剂。对结合模式的进一步分析表明,反向激动是通过一种不寻常的机制实现的。与其他报道的反向激动剂相反,在晶体结构中没有观察到螺旋12的直接相互作用或位移。尽管如此,化合物9 证明在大鼠迟发型超敏反应(DTH)炎症模型中有效。
