A group of podophyllotoxin (PPT) derivatives (7a-j) were synthesized by conjugating aryloxyacetanilide moieties to the 4'-hydroxyl of 4'-demethyl-4-deoxypodophyllotoxin (DDPT), and their anticancer activity was evaluated. It was found that the most potent compound 7d inhibited the proliferation of three cancer cell lines with sub to low micromolar IC50 values. Furthermore, it was demonstrated that
通过将芳氧基乙酰苯胺部分与4'-demethyl-4-deoxypodophyllotoxin(DDPT)的4'-羟基缀合,合成了一组鬼臼毒素(PPT)衍生物(7a-j),并评估了它们的抗癌活性。发现最有效的化合物7d以微摩尔IC 50值低抑制了三种癌细胞系的增殖。此外,已证明7d诱导MGC-803细胞中G2 / M期的细胞周期停滞,并调节细胞周期检查点蛋白如细胞周期蛋白A,细胞周期蛋白B,CDK1,cdc25c和p21的表达。最后,4 mg / kg的7d减少了小鼠HepG2异种移植的重量和体积。我们的发现表明7d可能是一种潜在的抗癌药。
