AbstractTwo series of diaziridinyl quinone isoxazole derivatives were prepared and evaluated for their cytotoxic activity against MCF7, HeLa, BT549, A549 and HEK293 cell lines and interaction with tubulin. Compounds (6a–m ) showed promising activity against all the 5 human cancer cell lines. Compounds 6a, 6e and 6 m were potent [IC50 ranging between 2.21 µg to 2.87 µg] on ER-positive MCF7 cell line similar to the commercially available drug molecule Doxorubicin. The results from docking models are in consistent with the experimental values which demonstrated the favourable binding modes of compounds 6a–m to the interface of α- and β-tubulin dimer.
摘要:制备了两系列二氮杂环喹喙醌异噁唑衍生物,并对它们在MCF7、HeLa、BT549、A549和HEK293细胞系中的细胞毒活性以及与微管的相互作用进行了评估。化合物(6a-m)对所有5种人类癌细胞系显示出良好的活性。化合物6a、6e和6m在ER阳性的MCF7细胞系上表现出强效【IC50范围在2.21 µg至2.87 µg之间】,类似于商业上可获得的药物多柔比星。对接模型的结果与实验值一致,表明化合物6a-m与α-和β-微管二聚体界面的结合模式是有利的。
