Abstract:

A Gadelle-Defaye method was used to synthesis per-6-amino-β-CD[β-CD-(NH2)7]. Then, different molecular weighted star β-CD-g-poly(L-glutamic acid)(β-CD-g-PLGA-ADH) was synthesised via "grafting-from" method. The hydrogel precursors, β-CD-g-PLGA-ADH and oxided alginate(ALG-CHO) were mixed to prepare β-CD-g-PLGA/ALG hydrogel. The effect of solid content and molecular weight of β-CD-g-PLGA on the properties of hydrogel was studied. Simvastatin(SIM) was used as a model drug, the drug loading and release behavior of β-CD-g-PLGA/ALG hydrogel were researched. The introduction of β-CD into hydrogel made it an effective SIM loading and sustained release system.

Key words: Injectable hydrogel, β-Cyclodextrin, Poly(L-glutamic acid), Sustained drug release
