  • Method of crosslinking glycosaminoglycans
    Patent number: 11807726
    Abstract: A new hydrogel made of crosslinked glycosaminoglycans, particularly crosslinked hyaluronic acid, chondroitin or chondroitin sulfate, having reversible linkages using boronic acid or boroxole derivatives leading to new benefits. Glycosaminoglycans that are crosslinked via an alkoxyboronate ester anion formed between a diol portion of a diol-functional moiety grafted to a first glycosaminoglycan and a boronate hemiester grafted to a second glycosaminoglycan.
    Type: Grant
    Filed: November 24, 2021
    Date of Patent: November 7, 2023
    Assignee: CENTRE NATIONAL DE LA RECHERCHE SCIENTIFIQUE

  • METHOD OF CROSSLINKING GLYCOSAMINOGLYCANS
    Publication number: 20200062868
    Abstract: A new hydrogel made of crosslinked glycosaminoglycans, particularly crosslinked hyaluronic acid, chondroitin or chondroitin sulfate, having reversible linkages using boroxole derivatives leading to new benefits. Glycosaminoglycans that are crosslinked via an alkoxyboronate ester anion formed between a backbone diol function of a first glycosaminoglycan and a boronate hemiester grafted to a second glycosaminoglycan.

  • METHOD OF CROSSLINKING GLYCOSAMINOGLYCANS
    Publication number: 20200002441
    Abstract: A new hydrogel made of double crosslinked glycosaminoglycans, particularly crosslinked hyaluronic acid, chondroitin or chondroitin sulfate, having reversible linkages using boronic acid or boroxole derivatives leading to new benefits. Double crosslinked glycosaminoglycans, one linkage via two ether bonds with a hydroxyl group of each of two glycosaminoglycans and another linkage via an alkoxyboronate ester anion formed between a boronate hemiester grafted to one of the glycosaminoglycans and a diol function of to the other glycosaminoglycan. The diol function may be a backbone diol function or a diol portion of a diol functional moiety grafted the other glycosaminoglycan.
