presents BCHHD 11b as a potent anticancer agent able to overcome drug resistance. In addition, compound 11b was able to serve as a chemical carrier for 99mTc and the in vivo biodistribution study of 99mTc-11b complex revealed a remarkable targeting ability of 99mTc into solid tumor showing that 99mTc-11b might be used as a promising radiopharmaceutical imaging agent for cancer.
当前的工作提出了新的香豆素酰肼-系列衍生物的合成和生物学评估,这些衍生物显示了使用阿霉素对耐药胰腺癌(Panc-1),肝细胞癌(HepG2)和白血病(CCRF)细胞系的体外广谱抗肿瘤活性作为参考标准。溴香豆素酰肼-衍生物(BCHHD)11b对所有测试的癌细胞系均显示出优异的抗癌活性。酶分析表明,由于胱天蛋白酶3/7的激活,BCHHD 11b诱导了细胞凋亡。此外,11b以剂量依赖性方式抑制GST和CYP3A4,诱导的细胞死亡可归因于代谢抑制。此外,11b基因芯片分析显示,处理过的细胞中许多与凋亡,细胞周期,肿瘤生长和抑制基因。以上所有内容均提出了BCHHD 11b,它是一种能够克服耐药性的有效抗癌剂。此外,化合物11b可以作为99mTc的化学载体,对99mTc-11b复合物的体内生物分布研究表明99mTc对实体瘤具有显着的靶向能力,表明99mTc-11b可以用作有前途的放射性药物显像剂对于癌症。
