    摘要： The invention relates to an enzyme which is able to degrade hyaluronic acid and which is produced by fungi of the genus Fistulina (especially Fistulina hepatica). The degradation proceeds by lyase mechanism in which double bonds between C4 and C5 of glucuronic acid are formed. The invention also includes the process of preparation and purification of the enzyme and a possible practical use thereof for the preparation of low-molecular hyaluronan or of cosmetic or pharmaceutical devices. Further, the invention relates to the method of preparation of low-molecular hyaluronan.

    摘要： The invention relates to the preparation and use of α,β-unsaturated aldehyde of hyaluronan having a double bond in the positions 4 and 5 and an aldehydic group in the position 6 of the glucosamine part of the polysaccharide. The method of preparation is based on dehydration of hyaluronan having an aldehydic group in the position 6 of the glucosamine part of the polysaccharide. Two methods have been described, which are dehydration in a solution or heating in solid state in absence of solvents, bases or other additives. This derivative allows stabilization of conjugates of hyaluronan with amino compounds by means of a multiple bond from the aldehyde side, and therefore, it is possible to effectively immobilize practically any compound containing an amino group to such modified hyaluronan in physiological conditions. In case of using a diamine or compounds or polymers containing three or more amino groups, it is possible to prepare crosslinked hyaluronan derivatives. The described solution brings along a significant advantage not only in the field of carriers of biologically active substances, but also in tissue engineering where crosslinking with biologically acceptable amino compounds in physiological conditions is very much demanded.

    摘要： The invention relates to a crosslinked hyaluronan derivative in the form of a hydrogel or microfibers, and to a method of preparation thereof, consisting in a C—C coupling reaction. The C—C coupling reaction is performed via reaction of a hyaluronan derivative carrying a terminal aryl-halide and/or aryl-borate group, and a hyaluronan derivative carrying an alkenyl or alkynyl group, in water, phosphates buffer or a mixture of an organic acid and an alcohol, and in the presence of a palladium active catalyst. The palladium active catalyst may be e.g. a complex of palladium (II) acetate and an inorganic or organic base, or a complex of palladium (II) and 2-amino-4,6-dihydroxypyrimidine.
