Biotin-Functionalized Multi-Stimuli-Responsive Polymeric Prodrug for Receptor-Mediated and Mitochondria-Targeted Codelivery of Camptothecin and Protocatechualdehyde
Triple-negative breast cancer (TNBC) remains difficult to treat because of limited molecular targets and multidrug resistance. Here, we develop CPB, a biodegradable poly(ε-caprolactone)-polymeric prodrug nanoplatform integrating biotin-mediated uptake, triphenylphosphonium- and quaternary-ammonium-driven mitochondria...
