Аннотация

pH- and thermo-sensitive hydrogels based on chitosan cross-linked with terephthaloyl diazide were synthesized. A new formulation of the polysaccharide modified with taxifolin (dihydroquercetin) was obtained by nucleophylic addition reaction resulting in the formation of urea and urethane bonds with a 1,4-phenylenediamine spacer. Sustained release of the effective agent (flavonoid) upon action of trypsin, which is one of the enzymes of the gastrointestinal tract, was observed.
