发现了一系列5,11-二氢-6 H-苯并[ e ]嘧啶[5,4- b ] [1,4]二氮杂-6-酮类作为选择性PI3K-δ/γ抑制剂
摘要:
PI3K-δ和PI3K-γ的双重抑制是血液恶性肿瘤的既定治疗策略。报道的选择性靶向PI3K-δ/γ的分子在化学上是相似的,并且基于异喹啉-1(2 H)-one或喹唑啉-4(3 H)-one支架。在这里,我们报告了基于5,11-二氢-6 H-苯并[ e ]嘧啶[5,4- b ] [1,4]二氮杂-6-的一系列有效的,选择性的PI3K-δ/γ抑制剂一种支架具有可比的生化效能和对PI3K信号传导的细胞作用。我们设想这些分子将为开发下一代PI3K-δ/γ靶向治疗剂提供有用的线索。
