Upregulation of mechanistic target of rapamycin (mTOR) signaling drives various types of cancers and neurological diseases. Rapamycin and its analogues (rapalogs) are first generation mTOR inhibitors, and selectively block mTOR complex 1 (TORC1) by an allosteric mechanism. In contrast, second generation ATP-binding site inhibitors of mTOR kinase (TORKi) target both TORC1 and TORC2. Here, we explore 3,6-dihydro-2H-pyran
雷帕霉素 (mTOR) 信号转导机制靶标的上调驱动各种类型的癌症和神经系统疾病。雷帕霉素及其类似物 (rapalogs) 是第一代 mTOR 抑制剂,可通过变构机制选择性地阻断 mTOR 复合物 1 (TORC1)。相反,mTOR 激酶的第二代 ATP 结合位点抑制剂 (TORKi) 靶向 TORC1 和 TORC2。在这里,我们探索了 3,6-dihydro-2 H - pyran (DHP) 和 tetrahydro-2 H - pyran (THP) 作为吗啉部分的电子等排体,从而为 TORKi 生成打开了一个新的化学空间。制备了 DHP 和 THP 取代的三嗪库,分子建模为构效关系研究提供了合理依据。最后,化合物11b[5-(4-(3-oxa-8-azabicyclo[3.2.1]octan-8-yl)-6-(tetrahydro-2 H -pyran-4-yl)-1,3,5-triazin-2
