Clinically, almost all anticancer drugs eventually fail to consistently benefit patients due to serious drug resistance. AKT is a key effector of the PI3K/AKT/mTOR pathway, which is closely related to the occurrence, development, and drug resistance of tumors. Herein, we first designed and synthesized 20 kinds of novel hybrid molecules targeting both tubulin and AKT based on a podophyllotoxin (PPT) skeleton
癌症是全球威胁人类健康的主要疾病,其中以非小细胞肺癌(NSCLC)最为致命。临床上,几乎所有的抗癌药物最终都因严重的耐药性而无法持续使患者受益。AKT是PI3K/AKT/mTOR通路的关键效应子,与肿瘤的发生、发展和耐药密切相关。在此,我们首先通过计算机辅助药物设计,基于鬼臼毒素(PPT)骨架设计并合成了20种同时靶向微管蛋白和AKT的新型杂化分子。通过CCK8法筛选出对H1975细胞抑制活性最强的化合物D1-1(IC 50 = 0.10 μM),其活性比PPT(IC 50 = 12.56 μM)高100倍,比吉非替尼高300倍( IC 50 = 32.15 μM)。亲和力分析结果表明,D1-1不仅保留了PPT的微管蛋白靶向性,而且表现出较强的AKT靶向性。随后的药理实验表明,D1-1通过抑制微管蛋白聚合和AKT通路激活,显着抑制H1975细胞的增殖和转移,并轻微诱导其凋亡。总的来说,这些
