Abstract

AbstractSummary: Catalase was chemically modified with an end‐group aminated dextran derivative via a carbodiimide catalyzed reaction. The enzymatic activity of catalase was increased after glycosidation with 4 mol of polymer. This modification improved the pharmacokinetic behavior of catalase, increasing by 7.8‐ and 20‐fold the plasma half‐life times for the α and β phases, and reducing by 176‐fold the total clearance after intravenous administration in rats.Schematic of the catalase dextran conjugate synthesized here.imageSchematic of the catalase dextran conjugate synthesized here.
