As an aspect of our ongoing research on developing novel antiproliferative agents, 31 new triazole–isoindoline hybrids bearing 3,4,5-trimethoxyphenyl moiety were synthesized and evaluated for their antiproliferative activity against four cancer cell lines (HepG2, HeLa, PC-3, and HCT116). Some compounds showed excellent potency, and compared to fluorouracil, the most promising compound 6s exhibited 5.8-, 4.3-, and 1.3- fold increase in activities against HeLa, HepG2, and PC-3 cell lines with IC50 values of 9.7, 10.7, and 16.8 μM, respectively. Moreover, structure–activity relationship studies indicated that a much shorter amide linkage and electron-withdrawing groups at phenyl ring of the acetamide fragment contribute to the antitumour activity.
作为我们正在进行的开发新型抗增殖剂研究的一个方面,我们合成了 31 种含有 3,4,5- 三甲氧基苯基的新三唑-异吲哚啉杂化物,并评估了它们对四种癌细胞系(HepG2、HeLa、PC-3 和 HCT116)的抗增殖活性。与氟尿嘧啶相比,最有前途的化合物 6s 对 HeLa、HepG2 和 PC-3 细胞株的活性分别增加了 5.8、4.3 和 1.3 倍,IC50 值分别为 9.7、10.7 和 16.8 μM。此外,结构-活性关系研究表明,乙酰胺片段更短的酰胺连接和苯环上的电子吸收基团有助于提高抗肿瘤活性。
