Research progress on tumor-targeting paclitaxel prodrugs / 药学实践杂志

ABSTRACT

Paclitaxel is a natural compound with efficient broad-spectrum antitumor activity .However ,the clinical ap-plication has been limited owing to the undesirable drawbacks ,such as the poor water-solubility ,cardiovascular toxicity and neurotoxicity .The design of paclitaxel prodrugs is an effective measure which can improve the drug's druggability ,alleviate its toxicity adverse effect and enhance its antitumor effect .With the in-depth research of prodrugs ,tumor-targeting paclitaxel pro-drugs which using the excessive receptors ,specific enzymes ,transporters ,reactive oxide species ,glutathione in tumor tissues as well as acidosis and hypoxia in tumors as specific targets ,have made great progress .The relevant literature about paclitaxel prodrugs were reviewed in this paper ,which targeted to the specific pathological and physiological features of tumor microenvi-ronment in recent years.
