We performed a biochemical screen against mTOR using in‐house small molecule library. Two novel, structurally distinct hits were identified. Among them, a novel oxadiazole scaffold compound (2) suppressed the phosphorylation of both S6K1 and Akt1 in HeLa cells. Docking study suggested that 2 is ATP‐competitive and shows a pi‐pi interaction with Trp2239 and hydrogen bonds with Trp2239 and Thr2245. Through
我们使用内部小分子文库对mTOR进行了生化筛选。确定了两个新颖的,结构上不同的命中。其中,新型的恶二唑支架化合物(2)抑制了HeLa细胞中S6K1和Akt1的
磷酸化。对接研究表明2具有
ATP竞争性,并显示与Trp2239的pi-pi相互作用以及与Trp2239和Thr2245的氢键。通过衍生化,鉴定出稍微更有效的类似物(2a),IC 50为9.6μM。我们的研究为发现新型有效的mTOR
抑制剂提供了一个起点。
