However, the poor solubility is a serious concern for intensive study and clinical application. We synthesized its analogs 1–9 by replacement of the trimethoxyphenyl of PL with an N-heteroaromatic ring and/or not introduction of 2-Cl. These compounds improved aqueous solubility and displayed potent anticancer activity. The most active compound 9 selectively enhanced ROS levels in colon cancer cells and inhibited
Piperlongumine(PL)选择性靶向多种癌细胞,并通过触发各种途径(包括凋亡,坏死和自噬)诱导其死亡。然而,差的溶解度是深入研究和临床应用的严重问题。我们合成了它的类似物1 - 9由替换PL的三
甲氧基苯基的与Ñ -heteroaromatic环和/或不引入2-的Cl。这些化合物改善了
水溶性,并显示出有效的抗癌活性。活性最高的化合物9选择性提高结肠癌细胞中的ROS
水平,抑制细胞增殖,但保留非肿瘤结肠细胞。重要的是9在HCT-116异种移植小鼠模型中可显着抑制肿瘤的生长,这表明这些基于N杂芳环的PL类似物值得进一步研究。
