Disulfiram (DSF) exerts potent anticancer activity via the formation of chelates with copper or zinc ions in tumor tissues, but the low abundance of these ions in the tumor cannot sustain its antitumor activity. Herein, we show that a zwitterionic water-soluble N-oxide polymer, poly[2-(N-oxide-N,N-dimethylamino)ethyl methacrylate] (OPDMA), can complex cupric ions and form nanogels (OPDMA/Cu), which efficiently deliver copper ions to tumor tissue to potentiate DSF significantly for effective antitumor therapy.

N-氧化物聚合物-铜离子纳米凝胶可增强双硫仑在癌症治疗中的作用。

双硫仑(DSF)通过在肿瘤组织中与铜或锌离子形成螯合物而发挥有效的抗癌活性,但是这些离子在肿瘤中的低含量不能维持其抗肿瘤活性。在这里,我们表明两性离子水溶性N-氧化物聚合物,聚[2-(N-氧化物-N,N-二甲基氨基)甲基丙烯酸乙酯](OPDMA),可以络合铜离子并形成纳米凝胶(OPDMA / Cu),可以有效地将铜离子输送到肿瘤组织,从而显着增强DSF,从而有效地进行抗肿瘤治疗。
