An esterase-activatable curcumin prodrug for tumor-targeting therapy

Abstract

A tumor-targeting therapy strategy is urgently needed to increase the accumulation of drugs in tumors and reduce the side effects in normal tissues. Herein, we developed an esterase-activatable curcumin prodrug Cur-RGD for tumor-targeting therapy. Armed with the tumor-targeting RGD peptide and in situ esterase-triggered drug release, this prodrug Cur-RGD can efficiently improve the therapeutic effect of curcumin in tumors.
