  发现苯磺酰胺衍生物作为有效的PI3K / mTOR双重抑制剂，具有体内抗肝细胞癌的功效

  摘要：

  磷酸肌醇3-激酶（PI3K）/蛋白激酶B（AKT）/雷帕霉素的哺乳动物靶标（mTOR）信号通路与细胞活性有关。在包括肝细胞癌（HCC）在内的各种癌症中发现了该信号通路的异常。提出PI3K / mTOR双重抑制剂通过靶向信号传导途径的多个点而具有增强的抗肿瘤功效。我们合成了一系列丙炔基取代的苯磺酰胺衍生物作为PI3K / mTOR双重抑制剂。化合物7k（NSC781406）被鉴定为高效双重抑制剂，在肝细胞癌BEL-7404异种移植模型中显示出有效的肿瘤生长抑制作用。化合物7k可能是HCC的潜在治疗药物候选物。

  A novel series of 4-alkynyl-quinoline derivatives were designed, synthesized and biologically evaluated for their PI3K alpha inhibitory activities and anti-proliferative effects against two cancer cell lines PC-3 and HCT-116. Most of them showed potent PI3K alpha inhibitory activities with IC50 values at low nanomolar level and good to excellent anti-proliferative effects against both cell lines. Among them, compound 15d, the most potent one, was selected for further biological evaluation. As a result, 15d displayed strong inhibitory activity against other class I PI3K isoforms (PI3K beta, PI3K gamma and PI3K delta) and mTOR with an acceptable kinase selectivity profile. Moreover, the western blot assay indicated that the phosphorylation of Akt, another downstream effector of PI3K, can be remarkably suppressed by 15d at cellular level. All these experimental results suggested that 15d is a potent PI3K/mTOR dual inhibitor and could serve as a promising lead compound for the development of anticancer agents.
