Preparation of Low-Molecular-Weight Heparins by Radiation-Induced Destruction

详细

Low-molecular-weight heparins (LMWHs) are widely used in medical practice. LMWHs are produced using various methods of controlled depolymerization of unfractionated heparin (UFH). Herein, a method for radiation-induced destruction of aqueous heparin solutions using a ⁶⁰Co gamma-irradiation source is presented. The optimal conditions for depolymerization of starting heparin were found. The anticoagulant activity of LMWHs was studied as a function of irradiation dose. The results allowed this LMWH production method to be recommended for development of new anticoagulants.
