A novel β-cyclodextrin (β-CD) graft copolymer was synthesized by immobilizing β-CD onto the linear chain of PVA through acetalization reaction.The optimum reaction condition was tested as that the feed weight ratio of β-CD-6-CHO with PVA is 4:1 at 70℃ for 2 h.The structures of PVA-β-CD were characterized by Infrared Spectroscopy (IR) and Nuclear Magnetic Resonance (NMR).The molecular inclusion complex of PVA-β-CD with camptothecin (CPT)
an anticancer drug
was studied.The results indicated that due to the inclusion of PVA-β-CD with the drug
the solubility of the CPT increased gready.And the cumulative release rate and extent of drug released from PVA-β-CD matrix can be effectively improved with the increase in β-CD content.
