Prostate tumor specific peptide-peptoid hybrid prodrugs.

Inspired by naturally occurring host defense peptides, cationic amphipathic peptoids provide a promising scaffold for anti-cancer therapeutics. Herein, we report a library of peptide-peptoid hybrid prodrugs that can be selectively activated by prostate cancer cells. We have identified several compounds demonstrating potent anti-cancer activity with good to moderate selectivity. We believe that these prodrugs can provide a useful design principle for next generation peptide-peptoid hybrid prodrugs.
