Sci Rep:硝酸益康唑抑制PI3K活性并促进肺癌细胞凋亡

2017-12-25 xiangting MedSci原创

这项研究证明,益康唑显著抑制裸鼠中的A549肿瘤生长。

磷脂酰肌醇-3-激酶(PI3K)/ AKT信号通路在许多细胞过程中起着关键作用,包括肺癌细胞的增殖,存活和分化。因此,PI3K是肺癌有希望的治疗靶点。

在这项研究中应用免费和开源的蛋白质-配体对接软件,筛选了3167个FDA批准的小分子,并确定了推定的PI3Kα抑制剂。其中,硝酸益康唑(一种抗真菌药)在NSCLC细胞系,包括H661(大细胞肺癌)和A549(腺癌)的病理类型中显示出降低细胞生存的最高活性。益康唑降低了p-AKT和Bcl-2的蛋白水平,但对ERK的磷酸化水平没有影响。它以剂量依赖性方式抑制细胞生长并促进细胞凋亡。此外,益康唑和顺铂的联合在H661和A549肺癌细胞系中分别表现出协同附加作用。

这项研究证明,益康唑显著抑制裸鼠中的A549肿瘤生长。表明益康唑是一种新的PI3K抑制剂和一种可单独或与顺铂联合用于肺癌治疗的潜在药物。
