Tumor-specific prodrug treatment renders the exclusive delivery of antitumor agents with the lowest untoward effects. In this work, we reported the synthesis and biological assessment of four NQO1-activatable combretastatin A-4 prodrugs constituted by active drug CA-4, different self-immolating linkers, and NQO1-responsive trigger groups. The in vitro antiproliferative activities showed that prodrug 4 displayed
特定于肿瘤的前药治疗使抗肿瘤药的排他性传递降到最低。在这项工作中,我们报告了由活性药物CA-4,不同的自消灭性接头和NQO1反应性触发基团构成的四种NQO1可激活的康维他汀A-4前药的合成和生物学评估。体外抗增殖活性表明,前药4对过表达NQO1,紫杉醇抗性A549细胞,低氧暴露的A549和HepG2细胞的肿瘤细胞具有更大的选择性毒性,与康布雷他汀A-4相比,对正常细胞的损伤较小,前药1,2,和3。此外,基于机理研究,NQO1触发了前药4有效释放母体药物康普他汀A-4并杀死肿瘤细胞。此外,我们还证明,在体内条件下,前药4的抗癌作用和安全性均高于康培他汀A-4。因此,根据以上结果,NQO1可以用作释放抗癌剂的特定递送系统。此外,前药4可以作为开发特定抗癌药的候选药物。
