HGC-27 cells with IC50 value of 0.39 ± 0.09 μM. Fluorescence imaging studies demonstrated that probe B12 could enter HGC-27 cells in a dose-dependent and time-dependent manner and was mainly accumulated in mitochondria. Preliminary biological mechanism studies indicated that B12 was able to inhibit cell cloning and migration. Further studies suggested that B12-induced apoptosis was related to the mitochondrial
Jiyuan Oridonin A ( JOA ) 是一种天然存在的ent -kaurane 二萜类化合物,在抗肿瘤药物开发领域具有显着的潜力。然而,其详细的抗癌作用机制尚未完全清楚。为了研究其抗癌作用模式,合成了与萘酰亚胺染料偶联的两个新型JOA荧光衍生物,并对其对五种选定的癌细胞系(MGC-803、SW1990、PC-3、TE-1 和HGC-27) 进行了评估。与JOA相比,绝大多数化合物的抗肿瘤活性都有所提高。其中,B12对 HGC-27 细胞具有良好的抗增殖活性,具有 IC50值为 0.39 ± 0.09 μM。荧光成像研究表明,探针B12能够以剂量依赖和时间依赖的方式进入HGC-27细胞,主要在线粒体中积累。初步生物学机制研究表明,B12能够抑制细胞克隆和迁移。进一步的研究表明,B12诱导的细胞凋亡与线粒体途径有关。总体而言,我们的结果为探索天然产物JOA的分子机制提供了新的方法
