This invention relates to macromolecular prodrugs having antitumor activity when activated by GSH, and methods for synthesizing and administering these to patients. More particularly, this invention relates to, inter alia, the synthesis and use of polyacrylamide carriers to target anticancer prodrugs to tumors, and to release active antitumor agents selectively in tumor cells. These active antitumor agents target the active site of the methylglyoxal-detoxifying enzyme glyoxalase I to thereby cause tumor regression.
本发明涉及通过GSH激活具有抗肿瘤活性的高分子前药,以及合成和给患者施用这些前药的方法。更具体地说,本发明涉及使用聚丙烯酰胺载体以将抗癌前药定向到肿瘤,并在肿瘤细胞中选择性地释放活性抗肿瘤剂的合成和使用。这些活性抗肿瘤剂靶向甲基乙二醛解毒酶甘氧醛酸酶I的活性位点,从而导致肿瘤退化。
