cell cycle arrest at G2/M phase. The extent of apoptosis induced by 3k and 3l was also determined. Moreover, the compounds produced a significant reduction in cellular microtubules for microtubule loss and potently inhibited the binding of [3H]colchicine to tubulin. Compounds 3k and 3l were proved to upregulate expression of proteins triggering apoptosis, such as p53, Bax, and decreased Bcl-2 overexpression
通过光谱方法和元素分析,设计,合成和确认了一系列新的二酰胺功能化合物。评价所有合成的化合物对HepG2
细胞系的抗增殖活性。化合物3k和3l被证明具有比参考化合物Combretastatin A-4等效的或更有效的抗癌活性。DNA流式细胞仪分析的结果表明细胞周期停滞在G2 / M期。还确定了3k和3l诱导的细胞凋亡程度。此外,该化合物使细胞微管的微管损失显着减少,并有效抑制[3H]
秋水仙碱与微管蛋白的结合。化合物3k和3l被证明可以上调触发细胞凋亡的蛋白质的表达,例如p53,Bax,
