Abstract

The efficacy of traditional chemotherapy often suffers from rapid clearance and off-target toxicity. Drug delivery systems and controlled release are applied to improve the therapeutic efficiencies of small-molecule drugs. In this work, two novel oxidative/reductive (Ox/Re) -sensitive and one non-sensitive Paclitaxel (PTX) prodrugs were synthesized with a maleimide group, which rapidly conjugates with albumin in vivo. Albumin serves as a good vehicle to deliver more prodrug to tumors due to the enhanced permeation and retention (EPR) effect. PTX was then released from the prodrugs in glutathione(GSH)/ reactive oxygen species(ROS)-rich tumor microenvironments. This bioresponsive prodrug strategy demonstrates potent chemotherapeutic efficiency in vivo and may be utilized in clinical cancer therapy.

摘要

传统化疗的疗效往往受到快速清除和靶向外毒性的影响。药物传递系统和控制释放被应用于提高小分子药物的治疗效率。在这项工作中,我们合成了两种新型的氧化/还原(Ox/Re)敏感和一种非敏感的紫杉醇(PTX)前药,它们都带有一个马来酰亚胺基团,可以在体内与白蛋白快速结合。白蛋白作为一种良好的载体,可以将更多的前药输送到肿瘤部位,因为它具有增强的渗透和保留(EPR)效应。PTX 随后会从谷胱甘肽(GSH)/活性氧(ROS)丰富的肿瘤微环境中的前药中释放出来。这种生物响应性前药策略在体内显示出强大的化疗效率,可能用于临床癌症治疗。
