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 depolymerization of said native EPSs followed by a step of sulphating the resulting depolymerized 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 &#x3bc;g (m) g/ml.

Sulfated depolymerized derivatives of exopolysaccharides (EPS) from mesophilic marine bacteria, method for preparing same, and uses thereof in tissue regeneration

The present invention relates to a biocidal composition including at least one active biocidal compound and at least one nonionic or anionic exopolysaccharide (EPS), the active biocidal compound being selected from at least one triamine having the following formula I, RNRR, formula I where Ris an aminoalkyl radical comprising a straight or branched chain having 2 to 16 carbon atoms, R2 is a hydrogen atom or a straight or branched alkyl chain having 1 to 18 carbon atoms, and Ris, independently from R, an aminoalkyl radical comprising a straight or branched chain having 2 to 16 carbon atoms or a &#x2014;CH&#x2014;CH&#x2014;CH&#x2014;NH&#x2014;Rradical, where Ris a saturated or unsaturated fatty acid chain including 4 to 20 carbon atoms or a mixture of C-Calkyl chains, characterized in that the biocidal composition includes, by weight and relative to the total weight of said biocidal composition, 0.5 to 90% of the biocidal compound and 0.1 to 10% of the exopolysaccharide.

Sulfated depolymerized derivatives of expolysaccharides (EPS) from mesophilic marine bacteria, method for preparing the same, and uses thereof in tissue regeneration

The invention relates to the use of certain low-molecular weight highly sulphated polysaccharide derivatives obtained from a bacterial polysaccharide for preparing a pharmaceutical composition suitable for modulating angiogenesis, particularly for use in accelerating vascular endothelial repair with a low haemorrhage risk in the event of thrombotic injuries.

Use of low-molecular-weight highly sulfated polysaccharide derivatives for modulating angiogenesis

The invention concerns the use of a polysaccharide excreted by thespecies for making a medicine with cicatrising activity, in particular bone repair activity. The invention also concerns a bone reconstruction biomaterial comprising said polysaccharide and a bone endoprosthesis whereof the surface is coated with such a polysaccharide.

[object Object]

The invention concerns a purified polysaccharide consisting of glucose, galactose, glucuronic acid, galacturonic acid, and pyruvate mannose, combined in a repeat hexasaccharide unit of formula (1), said polysaccharide comprising a saccharide units of formula (1), n being not less than 1. Said polysaccharide is useful in particular in the agri-foodstuff sector.
