In this paper, a series of millepachine derivatives were synthesized and evaluated as tubulin polymerization inhibitors. The optimal compound 5i, (3-hydroxy-4-methoxyphenyl)(5-methoxy-2,2-dimethyl-2H-chromen-8-yl)methanone, displayed the highest cytotoxicity toward a series of cancer cells (ranging from 18 to 45 nM of IC50). Further investigation revealed that 5i significantly repressed the multidrug
本文合成了一系列Millepachine衍生物,并作为微管蛋白聚合抑制剂进行了评估。最佳化合物5i(3-羟基-4-甲氧基苯基)(5-甲氧基-2,2-二甲基-2 H-铬基-8-基)甲酮对一系列癌细胞具有最高的细胞毒性(范围从18至IC 50的45 nM )。进一步的研究表明5i可以显着抑制多药耐药细胞(A549 / CDDP,A2780 / TAX),并且对人正常细胞(HLF,BJ)的细胞毒性很小。细胞机制研究表明5i诱导G2 / M期停滞和凋亡,这与线粒体膜电位(MMP)的崩溃有关。此外,蛋白质印迹分析表明5i可以改变细胞周期相关蛋白(例如Cyclin B1,Cdc25c,Cdc2)和某些凋亡相关蛋白(例如Bax,Bad,Bcl-2,Bcl-1x)的水平。最后,5i有效抑制了裸鼠中A549细胞的异种移植肿瘤的生长。
