Injectable Hydrogel Poly(styrene-alt-maleic anhydride)-Based for Controlled Drug Delivery |
초록 |
A novel new fast gelling hydrogel composed of copolymer Poly(styrene-alt-maleic anhydride) (PSMA) and poly(ethylene glycol) (PEG) with Inverse Electron Demand Deis-Alder (IEDDA) click reaction between tetrazines and norbornenes. The PSMA were subsequently functionalized with 3-(p-benzylamino)-1.2.4.5-tetrazine. The tetrazine groups, were reacted with dinorbonene chain-end functional polyethylene glycol as a cross-linking agent with IEDDA click reaction to produce a hydrogel. All the precursor materials were characterized by FT-IR, GPC, and 1H-NMR. The resulting hydrogel formation within several minutes and the storage modulus (G’) value of hydrogels was in range 0.3-1.7 kPa. The precursors exhibited practically no depressing effect on the normal HEK293 cell growth while the DOX·HCl-loaded hydrogel presented significant anticancer activity towards HeLa cells, which makes this biocompatible hydrogel potential for controlled drug release. |
