Highly selective PI3K inhibitors with subnanomolar PI3Kα potency and greater than 7000-fold selectivity against mTOR kinase were discovered through structure-based drug design (SBDD). These tetra-substituted thiophenes were also demonstrated to have good in vitro cellular potency and good in vivo oral antitumor activity in a mouse PI3K driven NCI-H1975 xenograft tumor model. Compounds with the desired
通过基于结构的药物设计 (SBDD),发现了具有亚纳摩尔 PI3Kα 效力和超过 7000 倍对 mTOR 激酶选择性的高选择性 PI3K 抑制剂。在小鼠 PI3K 驱动的 NCI-H1975 异种移植肿瘤模型中,这些四取代的噻吩也被证明具有良好的体外细胞效力和良好的体内口服抗肿瘤活性。还鉴定了具有所需人类 PK 预测和良好体外 ADMET 特性的化合物。在这篇通讯中,我们描述了安装关键的三唑部分以维持 PI3K 受体内复杂的 H 键网络的原理,从而获得更好的效力和选择性。此外,利用 C-4 苯基的优化来最大化化合物 mTOR 的选择性。
