CA 2570224

The invention relates to certain low-molecular weight sulphated polysaccharide derivatives of marine native exopolysaccharides (EPSs) excreted by mesophilic marine bacteria from a deep hydrothermal environment, wherein said derivatives can be obtained by means of a method which comprises a step of free radical depolymerisation of said native EPSs followed by a step of sulphating the resulting depolymerised derivatives. The present invention further relates to the use of said low-molecular weight sulphated polysaccharide derivatives as a wound-healing agent, particularly for preparing pharmaceutical compositions suitable for treating or preventing diseases of the connective tissues and particularly skin and gum tissues. The figure demonstrates how polysaccharide derivative GY 785 DRS according to the invention can stimulate fibroblast proliferation in latticed or reconstructed connective tissues at a concentration of 10 µg /ml.

La présente invention concerne des dérivés polysaccharidiques de faible masse molaire et sulfatés d'exopolysaccharides natifs (EPS) marins excrétés par des bactéries marines mésophiles issues du milieu hydrothermal profond, lesdits dérivés étant susceptibles d'être obtenus par le procédé comprenant une étape de dépolymérisation radicalaire desdits EPS natifs suivie d'une étape de sulfatation des dérivés dépolymérisés obtenus. La présente invention concerne également l'utilisation de ces dérivés polysaccharidiques de faible masse molaire et sulfatés en tant qu'agent cicatrisant, notamment pour la préparation de compositions pharmaceutiques permettant de traiter ou de prévenir des pathologies affectant les tissus conjonctifs, notamment dermiques et gingivaux. La figure de l'abrégé montre que dérivé polysaccharidique GY 785 DRS conforme à l'invention est capable à la concentration de 10 ~g/ml de stimuler la prolifération des fibroblastes dans des tissus conjonctifs reconstruits ou lattis.
