Release of Doxorubicin's Active Ingredient from the Hydrogels Derived from Acrylamide and their Biological Functions

摘要

Poly (HEMA/acrylamide/methyl methacrylate) (PHAM) and Poly (Acrylamide/methyl methacrylate)(PAM) polymers were synthesized for using in the release of Doxorubicin drug. Poly (HEMA/acrylamide/methyl methacrylate) (PHAM) and Poly (Acrylamide/methyl methacrylate) (PAM) composite hydrogels were prepared by a radical addition reaction in aqueous media formed by HEMA, acrylamide, and methacrylamide, with the presence of N, N'-methylenebisacrylamide. The characterization of the polymer was performed by FTIR analysis. Swelling and drug absorption properties of the polymers were analyzed in distilled water. Polymers' toxic effects were investigated by XTT assay. It has been observed that the entire drug, which was added to the solution with 1 g of polymer, was absorbed for 3.5 h. The absorption of these polymers was found quite high. PHAM polymer showed 800 swelling and PAM polymer showed 600 at 600 min. PHAM polymer was less toxic than PAM polymer. These results, this new polymer is very suitable for the release of Doxorubicin drug.
