Prostate-Specific Membrane Antigen and Esterase Dual Responsive Camptothecin–Oligopeptide Self-Assembled Nanoparticles for Efficient Anticancer Drug Delivery

The clinical utility of camptothecin (CPT) is restricted by poor aqueous solubility, high lipophilicity, active lactone ring instability, and off-targeted toxicities. We report here a prostate-specific membrane antigen (PSMA) and esterase dual responsive self-assembled nanoparticles (CPT-WT-H NPs) for highly efficient CPT delivery and effective cancer therapy.In this study, smart self-assembled nanoparticles CPT-WT-H NPs were elaborately...
