基于结构设计的新型mTOR抑制剂的抗宫颈癌活性研究(英文)
发布时间:2021-11-10 06:03
激酶mTOR是PI3K-AKT信号通路的关键组成部分,该激酶在宫颈癌细胞中被高度激活。本文运用基于结构的药物发现等手段发现了一系列mTOR激酶抑制剂并对其进行生物学评价,发现其可发挥有效的抗宫颈癌作用。酶活性测定结果显示化合物C3具有潜在的mTOR抑制作用(IC50=1.57μM)。随后利用分子对接和动力学模拟探究并预测m TOR激酶和C3的结合模式,初步探讨了化合物的构效关系。在多种肿瘤细胞系上进行细胞增殖活性实验时发现,C3对宫颈癌细胞He La表现出较好的增殖抑制活性(IC50=0.38μM)。此外, C3还能浓度依赖性地降低磷酸化核糖体S6 (p-S6)蛋白在HeLa细胞内的表达水平。值得注意的是,C3发挥显著的抗宫颈癌活性很有可能是mTOR通路和其他细胞内通路的共同作用。本研究表明C3可进一步开发为宫颈癌的治疗药物。
