Conjugates comprising a biodegradable polymer and uses therefor

摘要

The present invention provides biologically active agents covalently linked to a polymer. The polymer is preferably a biodegradable polymer. The biologically active agent is preferably a protein, such as an extracellular soluble protein, e.g., an extracellular enzyme. The enzyme can be an apyrase, e.g., NTP-Dase. Conjugates of the invention can be used as therapeutics in subjects. For example, a conjugate comprising an apyrase can be used for treating and preventing thrombosis, atherosclerotic plaque complications and vascular disorders.
