-en-1-one analogues replacing the cis double bond of combretastatin A-4 (CA-4) by 4/5-hydroxy cyclopentenone moieties was designed and synthesized. The analogues displayed potent cytotoxic activity (IC50<1 microg/mL) against a panel of human cancer cell lines and endothelial cells. The most potent analogues 11 and 42 belonging to the 5-hydroxy cyclopentenone class were further evaluated for their mechanism
一个新的2,3-二芳基-4 / 5-羟基-环戊-2-烯-1-酮类似物系列被4 / 5-羟基环戊烯酮部分取代了康美他汀A-4(CA-4)的顺式双键是设计和合成。该类似物显示出对一组人类癌细胞系和内皮细胞的有效细胞毒性活性(IC50 <1 microg / mL)。进一步评估了属于5-羟基环戊烯酮类别的最有效的类似物11和42的作用机理。两种类似物均导致细胞周期停滞在G2 / M期,并诱导内皮细胞凋亡。42的抗微管蛋白特性优于11,与CA-4相当。与CA-4相比,化合物42具有更好的水溶性,代谢稳定性和药代动力学特征,并且在人结肠异种移植模型中也显示出明显的肿瘤消退。
