no PI3K/mTOR dual inhibitor has been approved by the FDA yet. Therefore, it is still essential to discover a candidate with good efficacy and low toxicity. In our design, a series of imidazo[1,2-a]pyridine derivatives had been synthesized and subjected to activity assessment in vitro and in vivo. 15a was proved to be a potent PI3K/mTOR dual inhibitor with excellent kinase selectivity, modest plasma
PI3K-Akt-mTOR信号传导途径已被验证为癌症治疗的有效靶向途径。但是,尚未有FDA批准
PI3K / mTOR双
抑制剂。因此,寻找具有良好疗效和低毒性的候选药物仍然至关重要。在我们的设计中,已合成了一系列
咪唑并[1,2-a]
吡啶衍生物,并进行了体内和体外活性评估。15a被证明是一种有效的
PI3K / mTOR双重
抑制剂,具有出色的激酶选择性,适度的血浆清除率和可接受的口服
生物利用度。此外,15a在HCT116和HT-29异种移植物中显示出对肿瘤生长的显着抑制作用,而对体重没有明显影响。
