Polymeric Systems with Antithrombin Activity for Thermally Activated Targeting

Polymeric Systems with Antithrombin Activity for Thermally Activated Targeting Copolymers of N,N-diethylacrylamide and N-acryloylphthalimide with a lower critical solution temperature (LCST) were synthesized by radical copolymerization. Polymeric systems with antithrombin activity and an LCST were prepared via a reaction of amino groups of hirudin with phthalimide groups of the copolymers. On increasing hirudin content, the LCST of the polymeric systems increased. The antithrombin activity of polymeric systems obtained by hirudin immobilization on copolymer carriers was inversely related to the content of the copolymer, amounting to 6% of the activity of native hirudin. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Applied Biochemistry and Microbiology Springer Journals

Abstract

Copolymers of N,N-diethylacrylamide and N-acryloylphthalimide with a lower critical solution temperature (LCST) were synthesized by radical copolymerization. Polymeric systems with antithrombin activity and an LCST were prepared via a reaction of amino groups of hirudin with phthalimide groups of the copolymers. On increasing hirudin content, the LCST of the polymeric systems increased. The antithrombin activity of polymeric systems obtained by hirudin immobilization on copolymer carriers was inversely related to the content of the copolymer, amounting to 6% of the activity of native hirudin.
