Abstract: A skin care composition is disclosed comprising at least one exopolysaccharide (EPS) originating from a microbial mat, the EPS being in a concentration of about 0.001% w/w to about 1.5% w/w of the composition. Uses and methods of use thereof. In specific embodiments, the EPSs are derived from microorganisms isolated from microbial mats found in French Polynesia. The composition is useful in reducing signs of skin aging and environmental damage by altering skin cell metabolism and improving hydration.

Abstract: Provided is a plant derived extract including inhibitory activity against one or more extracellular proteases which degrade human tissue matrix. Moreover, the amount of inhibitory activity in an extract can be increased by stressing the plant prior to forming an extract. These extracts are each prepared by a process and demonstrate the ability to inhibit one or more extracellular proteases which degrade human tissue matrix. Libraries of extracts can be prepared from stressed and non-stressed plants, where each of the extracts demonstrate inhibitory activity against on or more extracellular protease inhibitors. Alternatively, semi-purified and purified inhibitory compounds can be isolated from the extracts. In one aspect, these extracts with inhibitory activity can be used during protein purification to minimize degradation due to extracellular proteases.
Abstract: A compound of the formula I: R-A-Gly-His-B (I) wherein: A and B are independently of each other a L-lysine residue, a D-lysine residue, or a L- or D-lysine residue in which the NH2 group of the side chain comprises a modification, where-in said modification is (i) a replacement with a hydrogen, (ii) an acetylation, (iii) a benzoylation, or (iv) a palmitoylation; GIy is a glycine residue; His is a L- or D-histidine residue; R is CH3—(CH2)n—CO—, wherein n=2, 3, 4, 5, 6, 7 or 8; R? is a group of formula (II): N(Z)(Z?) (II) wherein: Z and Z? is hydrogen, a methyl group, an ethyl group, a phenyl group, an hexyl group, a decyl group or an hexadecyl group; or a racemate, an enantiomer or a diastereomer thereof, or mixtures thereof, or a salt thereof.

Abstract: A method for inhibiting the release of one or more of IL-8, PGE2 and VEGF by a cell activated during an inflammatory process, said method comprising administering to said cell an anti-inflammatory polysaccharide composition comprising fucans and galactans to a cell, wherein the ratio of fucans to galactans in said composition enables a reduction in the cytotoxicity of said galactans and an anti-inflammatory composition comprising a ratio of brown algae fucans/red algae galactans of ranging from about 2.5/1 (w/w) to about 40/1 (w/w), the galactans having a molecular weight higher than about 100 kDa, and the fucans having a molecular weight ranging from about 0.1 kDa and 100 kDa.
Abstract: A use of an anti-inflammatory polysaccharides composition comprising fucans and galactans to inhibit the release of one or more of IL-8, PGE2 and VEGF by a cell activated during an inflammatory process and an anti-inflammatory composition comprising a ratio of brown algae fucans/red algae galactans of between about 2.5/1 (w/w) to about 40/1 (w/w), the galactans having a molecular weight higher than about 100 kDa, and the fucans having a molecular weight between about 0.1 kDa and 100 kDa.
