We report a strategy of utilizing irreversible cysteine cathepsin inhibitor as trapping agent to increase the tumor residence time of receptor-targeted agents. The targeted constructs incorporating these cysteine cathepsin trapping agents were able to form high molecular weight adducts with intracellular cysteine cathepsins, thus achieving superior retention in tumor tissues.
我们报告了一种利用不可逆的半胱氨酸组织蛋白酶抑制剂作为捕获剂来增加受体靶向剂在肿瘤中的驻留时间的策略。结合这些半胱氨酸组织蛋白酶捕获剂的靶向构建体能够与细胞内的半胱氨酸组织蛋白酶形成高分子量加合物,从而在肿瘤组织中实现更好的保留。
