of our program to discover ATP-competitive mTOR inhibitors that demonstrate improved pharmacokinetic properties and selectivity compared to our previous leads. Through targeted SAR and structure-guided design, new imidazopyridine and imidazopyridazine scaffolds were identified that demonstrated superior inhibition of mTOR in cellular assays, selectivity over the closely related PIKK family and improved
mTOR是多种生长因子下游细胞信号传导的关键调节剂。mTOR / PI3K / AKT途径在人类癌症中经常发生突变,因此是重要的肿瘤学靶标。在本文中,我们报告了我们开发发现与ATP竞争的mTOR抑制剂的程序的进展,这些抑制剂与我们以前的产品相比具有更高的药代动力学特性和选择性。通过有针对性的SAR和结构导向的设计,鉴定出了新的咪唑并吡啶和咪唑并哒嗪支架,它们在细胞测定中表现出对mTOR的优异抑制作用,在密切相关的PIKK家族中具有选择性,并且比我们以前报道的苯并咪唑系列具有更高的体内清除率。
