Abstract:
Objective Mannitol-poly(D,L-lactide-co-glycolide) (M-PLGA),a star-shaped biodegradable polymer,was synthesized with the intent in this research,to provide novel nanoformulation for cervical cancer chemotherapy.Methods The novel star-shaped copolymer was prepared by ring-opening polymerization,and characterized by NMR.The docetaxel-loaded M-PLGA nanoparticles,prepared by modified nano-precipitation method,were observed to be near-spherical shape with narrow size distribution.Results The CLSM results showed the uptake level of M-PLGA NPs was higher than PLGA NPs in Hela cells.A significantly higher level of cytotoxicity was achieved by docetaxel-loaded M-PLGA NPs than that of commercial Taxotere and docetaxel-loaded PLGA NPs,indicating that the star-shaped biodegradable polymer M-PLGA could be superior to the linear polymer PLGA as a drug carrier.The study on drug loading and encapsulation efficiency also proved that star-shaped M-PLGA could carry higher level of drug than linear polymer,therefore could be more efficient for cancer treatment.Conclusions In conclusion,the star-shaped M-PLGA copolymer may be used as a potential and promising drug-loaded biomaterial applied in developing novel nanoformulations for cervical cancer therapy.
