Parthenolide is an important sesquiterpene lactone with potent anticancer activities. In order to further improve its biological activity, a series of parthenolide semicarbazone or thiosemicarbazone derivatives was synthesized and evaluated for their anticancer activity. Derivatives were tested in vitro against 5 human tumor cell lines, and many of these showed higher cytotoxicity than parthenolide. Five compounds were further studied for their antitumor activity in mice. The in vivo result indicated that compound 4d showed both promising antitumor activity against mice colon tumor and small side effects on immune systems. The cell apoptosis and cell cycle distribution of compound 4d were also studied. Molecular docking studies revealed multiple interactions between 4d and NF-κB. Our findings demonstrate the potential of semicarbazones as a promising type of compounds with anticancer activity.

偏苯二酚是一种重要的倍半萜内酯，具有有效的抗癌活性。为了进一步提高其生物活性，合成了一系列的小白菊内酯半卡巴or或硫代半卡巴zone衍生物，并对其抗癌活性进行了评估。衍生物在体外针对5种人类肿瘤细胞系进行了测试，其中许多都显示出比单杀氰菊酯更高的细胞毒性。进一步研究了五种化合物在小鼠中的抗肿瘤活性。该体内结果表明，化合物4D既表现出有前途的抗小鼠结肠肿瘤和免疫系统副作用小的抗肿瘤活性。化合物4d的细胞凋亡和细胞周期分布还进行了研究。分子对接研究揭示之间的多重相互作用4D和NF- κ B.我们的研究结果表明缩氨基脲作为具有抗癌活性的有前途的类型的化合物的潜力。
