  Purpose: We developed a ROS-responsive effective drug delivery system to overcoming multidrug resistance(MDR)of oral squamous cell carcinoma(OSCC).Methods: The ROS-responsive crosslinked polymeric micelles(Cinnamaldehyde-Loaded HPG-7-ethyl-10-hydroxyl-camptothecin,CA-LoadedHPG-SN38)were successfully prepared by the selfassembly of amphiphilic HPG-SN38 and CA.And amphiphilic HPG-SN38 that conjugate via a thioether chain copolymer was characterized using fourier transformed infrared spectroscopy(FTIR),nuclear magnetic resonance(NMR),and gel permeation chromatography(GPC)analysis.CA-Loaded HPG-SN38 Micelles was characterized using transmission electron microscopy(TEM)dynamic light scattering(DLS),critical micell concentration(CC)and Ultra Violet(UV).
