  The subject-matter of the invention is a photoreactive derivative of hyaluronic acid (formula I) and the method of preparation thereof, where first an aldehyde derivative of hyaluronic acid is prepared, oxidized in the position 6 of the glucosamine cycle and then the oxidized derivative reacts with an amine carrying a photoreactive species, for example 1-(2-aminoethyl)pyridine-2(1H)-one, in the presence of a reducing agent, forming a photoreactive derivative. The prepared photoreactive derivative may be then photocrosslinked, wherein the reaction is based on [4+4] photocycloaddition. Moreover, the invention relates to a 3D-crosslinked derivative of hyaluronic acid (formula II) which exhibits an increased hydrolytic stability and improved sorption properties, with the possibility of a further design of the physical properties thereof according to the requirements of the final applications, and moreover, to the use thereof in tissue engineering, regenerative medicine, medical agents or formulations or cosmetics.

  本发明的主题是透明质酸的光反应衍生物（公式I）及其制备方法，首先制备透明质酸的醛衍生物，将其在葡萄糖胺环的6位氧化，然后将氧化衍生物与携带光反应物种的胺（例如1-（2-氨基乙基）吡啶-2（1H）-酮）在还原剂的存在下反应，形成光反应衍生物。制备好的光反应衍生物可以进行光交联，反应基于[4+4]光环加成。此外，本发明还涉及透明质酸的三维交联衍生物（公式II），其具有增强的水解稳定性和改进的吸附性能，并且可以根据最终应用的要求进一步设计其物理性质，此外，还可将其用于组织工程、再生医学、医用药剂或制剂或化妆品。

  The subject-matter of the invention is a photoreactive derivative of hyaluronic acid (formula I) and the method of preparation thereof, where first an aldehyde derivative of hyaluronic acid is prepared, oxidized in the position 6 of the glucosamine cycle and then the oxidized derivative reacts with an amine carrying a photoreactive species, for example l-(2- aminoethyl)pyridine-2(lH)-one, in the presence of a reducing agent, forming a photoreactive derivative. The prepared photoreactive derivative may be then photocrosslinked, wherein the reaction is based on [4+4] photocycloaddition. Moreover, the invention relates to a 3D- crosslinked derivative of hyaluronic acid (formula II) which exhibits an increased hydrolytic stability and improved sorption properties, with the possibility of a further design of the physical properties thereof according to the requirements of the final applications, and moreover, to the use thereof in tissue engineering, regenerative medicine, medical agents or formulations or cosmetics.
