CROSSLINKED BIOMIMETIC RANDOM COPOLYMER MICELLES AS POTENTIAL ANTI-CANCER DRUG DELIVERY VEHICLE
Amphiphilic random copolymers based on 2-(methacryloxyethyl) phosphorylcholine, stearyl methacrylate and trimethoxysilylpropyl methacrylate were synthesized using monomer-starved free radical polymerization method. The formation of micelles with cell outer membrane mimetic structure in aqueous solution was confirmed by fluorescence probe technique and scanning electron microscopy (SEM). Micellar stability against dilution and adjustable permeability were obtained by covalently crosslinking of the trimethoxysilyl groups in the micelle. The anti-cancer drug adriamycin (ADR) was incorporated into the micelles by oil-in-water method. The entrapped drug presents a sustained and remarkably slower release behavior without obvious burst effect.
