Abstract:
A method of preparing a hydrogel product comprising crosslinked glycosaminoglycan molecules, said method comprising: i) providing a glycosaminoglycan crosslinked by amide bonds, wherein the crosslinked glycosaminoglycans comprise residual amine groups; and ii) acylating residual amine groups of the crosslinked glycosaminoglycans provided in i) to form acylated crosslinked glycosaminoglycans.
Abstract:
The present invention relates in one aspect to a conjugate of a mucopolysaccharide or mucopolysaccharidic fraction and a cellular wall fragment of a bacterium belonging to the Corynebacterium genus, and in particular to the Corynebacterium granulosum species, also named P40. The conjugate of the invention is applied to medicine, in particular for topical treatment of infections, dermatological affections, such as psoriasis, acne, allergic reactions, such as rashes and eczema, and in vaginal mucosae affections.
Abstract:
The present invention discloses a matrix comprising a modified polysaccharide consisting of repeating disaccharide units whereby in at least 11 % of the disaccharide units one primary alcohol group is oxidized into a carboxylic acid group.
Abstract:
Therapeutic compositions and/or formulations are provided, comprising: at least one cross- linked protein matrix, wherein the at least one cross-linked protein matrix comprises at least one protein residue and at least one saccharide-containing residue, and methods of producing the same. The cross-linked protein matrix may be derived from cross-linking a full length or substantially full length protein, such as tropoelastin, elastin, albumin, collagen, collagen monomers, immunoglobulins, insulin, and/or derivatives or combinations thereof, with a saccharide containing cross-linking agent, such as a polysaccharide cross-linking agent derived from, for example, hyaluronic acid or a cellulose derivative. The therapeutic compositions may be administered topically or by injection. The present disclosure also provides methods, systems, and/or kits for the preparation and/or formulation of the compositions disclosed herein.
Abstract:
Disclosed is a process for the production of chondroitin sulphate,wherein N-acetyl-galactosamine residues sulphated at the 4-or 6-positions are present on the same polysaccharide chain.
Abstract:
The present invention relates to a process for the synthesis of conjugates of glycosaminoglycanes (GAG) with biologically active molecules of varying nature, comprising small molecules and macro-molecules. In particular, the present invention relates to the conjugation of hyaluronic acid (HA) and its derivatives with polypeptides and proteins with a biological action, such as, for example, interferons, erythropoietins, growth factors, insulin, cytokines, antibodies and hormones. An object of the present invention also relates to isolatable intermediates obtained by the partial or total reaction of GAG with protected amino aldehydes in the conjugation process mentioned above.
