Sorafenib (SRF) is a well-known tyrosine kinase inhibiting anticancer drug which iseffectual against multiple carcinomas especially gastric cancers by targeting the Ras/Raf/Mek/Erk cascade pathway and blocking the tumor cell proliferation. In the present work, we have reduced graphene oxide (GO) in presence of sorafenib using ascorbic as green reducing agent for the treatment of gastric cancers. Sorafenib reduced graphene oxide (SRGO) were obtained with a transparent and smoothmorphology. The drug loaded SRGO has presented significant cytotoxic effect against SGC7901 cancer cells when compared to that of the free SRF and blank NPs in the equivalent concentrations. Additionally, from the Hoechst 33382 staining study it was evident that the cells in untreated groups remained intact with its round shape and intact nuclei while the SRGO treated cells have shown a cell transformation with apoptosis of gastric cancer cell lines. Based on these results, we can conclude that SRGO might extend an enormous prospective in the treatment of gastric cancers.
索拉非尼(SRF)是一种著名的酪氨酸激酶抑制剂抗癌药物,通过靶向 Ras/Raf/Mek/Erk 级联途径和阻断肿瘤细胞增殖,对多种癌症特别是胃癌有效。在本工作中,我们在存在索拉非尼的情况下使用抗坏血酸作为绿色还原剂还原氧化石墨烯(GO),用于治疗胃癌。得到的索拉非尼还原氧化石墨烯(SRGO)具有透明光滑的形态。与等浓度的游离 SRF 和空白 NPs 相比,负载药物的 SRGO 对 SGC7901 癌细胞表现出显著的细胞毒性作用。此外,从 Hoechst 33382 染色研究中可以明显看出,未经处理的细胞保持完整,呈圆形且细胞核完整,而 SRGO 处理的细胞则表现出胃癌细胞系的细胞转化和凋亡。基于这些结果,我们可以得出结论,SRGO 可能在胃癌治疗中具有广阔的应用前景。
