A biotin-guided fluorescent-peptide drug delivery system for cancer treatment†
Abstract
Herein, we present a fluorescent-peptide drug delivery system composed of biotin–naphthalimide–HJ inhibitor peptide2, prodrug 1. Treatment of 1 to biotin receptor-positive HepG2 cells, which are resistant to high concentrations of the HJ inhibitor peptide2, decreased cell viability and increased intracellular fluorescence.
