previous published core structures, pyrido[2.3-D]pyrimidin-7-one and pteridinone, as PI3K/mTOR dual inhibitors. This design results in potent PI3K/mTOR dual inhibitors and the purposed intra-molecular hydrogen bonding structure is well supported by co-crystal structure in PI3Kγ enzyme. In addition, a novel synthetic route was developed for these analogs.
将分子内氢键引入到喹唑啉基序中以形成假环(分子内H键支架,iMHBS),以模仿我们之前发表的核心结构,吡啶并[2.3 - D ]嘧啶-7-和哌啶酮, PI3K / mTOR双重抑制剂。该设计产生有效的PI3K / mTOR双重抑制剂,并且PI3Kγ酶的共晶结构很好地支持了目的分子内氢键结构。另外,针对这些类似物开发了新颖的合成途径。
