Modified serine proteinase inhibitors and applications thereof

Abstract

In one aspect, the disclosure relates to modified serine proteinase inhibitors with an enhanced affinity to components of the extracellular matrix, including glycosaminoglycans. The modified serine proteinase inhibitors maintain their original structure and bioactivity while simultaneously exhibiting a higher positive charge density at their glycosaminoglycan-binding surface. Furthermore, the ECM-binding affinity can be tuned by systematically increasing the number of cationic amino acid residues and/or decreasing the number of anionic amino acid residues at the glycosaminoglycan-binding surface. Also disclosed are vectors for producing the modified serine proteinase inhibitors and pharmaceutical conditions incorporating the modified serine proteinase inhibitors.
