in cells, tissues and organs. In order to address these problems, we have designed and synthesized a novel berberine derivative BBR-BODIPY bearing a fluorescent tag that allows screening its interaction with the targeted cells. It was shown that the synthesized fluorescent derivative could penetrate into human breast carcinoma MCF7 cells, and then induced apoptosis detected by the Western Blot analysis
小ber碱是天然存在的
异喹啉生物碱,具有开发抗癌药物的巨大潜力。然而,问题仍然是对小ber碱的抗癌作用机理的了解不足。它取决于对小ber碱药代动力学的评估,即监测其在细胞,组织和器官中的摄取和分布。为了解决这些问题,我们设计并合成了一种新型的小ber碱衍
生物BBR-BODIPY带有荧光标签,可以筛选其与靶细胞的相互作用。结果表明,合成的荧光衍
生物可以穿透人乳腺癌MCF7细胞,然后通过Western Blot分析检测其凋亡,其原因是线粒体Cleaved Caspase释放的凋亡相关蛋白Bax,Bcl2和Cyto C的表达发生了改变。 9,Cleaved PARP,Pro-Caspase 3和Cleaved Caspase3。MitoTracker分析的结果,然后用共聚焦显微镜对BBR-BODIPY进行亚细胞定位即使在低浓度下,MCF7中的细胞也显示出优异的细胞穿透能力,线粒体是其积累的主要部位。连同Western
