A novel class of potent PI3Kδ inhibitors with >1000-fold selectivity against other class I PI3K isoforms is described. Optimization of the substituents on a triazole aminopyrazine scaffold, emerging from an in-house PI3Kα program, turned moderately selective PI3Kδ compounds into highly potent and selective PI3Kδ inhibitors. These efforts resulted in a series of aminopyrazines with PI3Kδ IC50 ⩽ 1 nM
描述了一种新型的强效PI3Kδ抑制剂,对其他I类PI3K同工型具有> 1000倍的选择性。内部PI3Kα程序对三唑氨基吡嗪骨架上的取代基进行了优化,从而将中等选择性的PI3Kδ化合物转变为高效且选择性的PI3Kδ抑制剂。这些努力的结果是与PI3KδIC一系列aminopyrazines的50 ⩽1nM的在酶测定中,一些迄今发表的最有选择性PI3Kδ抑制剂,在20-120 nM的JEKO细胞测定中的细胞潜能。
