Publication number: 20190249166Abstract: The present invention provides a method for inhibiting chondroitinase activity in a substrate by introducing a non-substrate glycosaminoglycan (GAG) to the substrate containing the chondroitinase. The non-substrate GAG is undegradable by chondroitinase. The GAG may be administered as a single dose or in multiple doses. The chondroitinase may be Chondroitinase B, Chondroitinase C, Chondroitinase AC, or Chondroitinase ABC. The substrate may be one or more of dermatan sulfate, hyaluronic acid, chondroitin sulfate, or derivatives thereof. The non-substrate GAG may be from naturally unbranched homo-polysaccharide, unnaturally branched GAG, or a hybrid GAG molecule fused of two or three GAG chains, being produced by chemical synthesis or enzymatic reaction. The non-substrate GAG may be heparin, heparan sulfate, and keratan sulfate. The non-substrate GAG may bind to the active residue of the chondroitinase when being introduced to the substrate such that the chondroitinase is no longer enzymatically active.Type: ApplicationFiled: January 23, 2019Publication date: August 15, 2019Inventor: Bing Lou WONG
