The retinoic acid receptor-related orphan nuclear receptor γt (RORγt), a promising therapeutic target, is a major transcription factor of genes related to psoriasis pathogenesis such as interleukin (IL)-17A, IL-22, and IL-23R. On the basis of the X-ray cocrystal structure of RORγt with 1a, an analogue of the known piperazine RORγt inverse agonist 1, triazolopyridine derivatives of 1 were designed and
视黄酸受体相关的孤儿核受体γt(RORγt)是一种有前途的治疗靶点,是与牛皮癣发病相关的基因的主要转录因子,例如白介素(IL)-17A,IL-22和IL-23R。基于RORγt与1a的X射线共晶体结构,设计并合成了已知的哌嗪RORγt逆激动剂1的类似物,并合成了1的三唑并吡啶衍生物,发现类似物3a是有效的RORγt逆激动剂。对3a的构效关系研究,专注于其代谢不稳定的环戊基环和中央哌嗪核心的治疗,导致了一个新的类似物,即6-甲基-N-(7-甲基-8-(((2S, 4S)-2-甲基-1-(4,4,4-三氟-3-(三氟甲基)丁酰基)哌啶-4-基)氧基)[1,2,4]三唑[1,5-a]吡啶- 6-基)烟酰胺(5a),具有很强的RORγt抑制活性和良好的药代动力学特征。此外,在人全血分析和小鼠IL-18 / 23诱导的细胞因子表达模型中对5a的体外和体内评估显示出其对IL-17A产生的强大且剂量依赖性的抑制作用。
