Title (EN) CROSSLINKED AMIDE DERIVATIVES OF HYALURONIC ACID AND MANUFACTURING METHOD THEREOF
(FR) DERIVES AMIDIQUES RETICULES D'ACIDE HYALURONIQUE ET PROCEDE DE FABRICATION DE CEUX-CI
Abstract: front page image
(EN)The present invention relates to water-insoluble, crosslinked amide derivatives of hyaluronic acid and manufacturing method thereof, where the amide derivatives of hyaluronic acid are characterized by crosslinking, of polymer or oligomer having two or more amine groups, with hyaluronic acid or its hyaluronate salts through amidation reaction.The water-insoluble, crosslinked amide derivatives of hyaluronic acid according to the present invention may be diversely used for prevention of adhesion after surgical operation, correction of facial wrinkles, dermal augmentation, tissue engineering, osteoarthritic viscosupplement etc.
(FR)La présente invention concerne des dérivés amidiques réticulés d'acide hyaluronique insolubles dans l'eau et un procédé de fabrication de ceux-ci, lesdits dérivés amidiques d'acide hyaluronique se caractérisant par la réticulation d'un polymère ou d'un oligomère comprenant deux ou plusieurs groupes amines avec de l'acide hyaluronique ou ses sels d'hyaluronate par une réaction d'amidation. Les dérivés amidiques réticulés d'acide hyaluronique insolubles dans l'eau de la présente invention peuvent être utilisés de diverses manières dans la prévention de l'adhérence après une opération chirurgicale, la correction des rides faciales, l'augmentation cutanée, le génie tissulaire, les viscosuppléments ostéoarthritiques, etc..
