important role in the development and maintenance of the skin barrier. We herein report the discovery of triazolopyridine derivatives as a new class of AhR agonists. Structure-activity relationship analyses led to the identification of the most active compound, 6-bromo-2-(4-bromophenyl)-[1,2,4]triazolo[1,5-a]pyridine (12a), with an EC50 (50% effective concentration) value of 0.03 nM. Compound 12a could
芳烃受体(AhR)是一种配体依赖性转录因子,可调节Th17/22和Treg细胞的免疫平衡,在皮肤屏障的发育和维持中发挥重要作用。我们在此报告了作为一类新的 AhR 激动剂的三唑并吡啶衍生物的发现。结构-活性关系分析导致鉴定出最活跃的化合物 6-bromo-2-(4-bromophenyl)-[1,2,4]triazolo[1,5- a ]pyridine ( 12a ),具有 EC 50(50%有效浓度)值为0.03 nM。化合物12a可以诱导AhR的快速核富集,触发下游基因的转录,促进皮肤屏障修复。12a的局部或口服给药可显着减轻咪喹莫特(IMQ)诱导的银屑病样皮肤病变。考虑到优异的体内抗银屑病活性和良好的药代动力学特性,12a可能是一种很有前途的先导化合物,用于发现抗银屑病药物,值得进一步研究。
