Definitions

  • R is hydrogen or any substitute and the co-oxidant is sodium hypochlorite (NaClO) or trichloroisocyanuric acid (TCC).
  • NaClO sodium hypochlorite
  • TCC trichloroisocyanuric acid
  • the hyaluronic acid is an important polysaccharide, composed of two repeating units of P-(l,3)-D-glucuronic acid and -(l,4)-N-acetyl-D-glucosamine.
  • the molecular weight depending on the method of isolation and on the source material, is within the range from 5.10 4 to 5.10 6 g.mol '1 .
  • the hyaluronic acid or its sodium salt hyaluronan is an essential component of connective tissues, synovial fluid of joints, and plays an important role in biological processes, such as hydratation, organization of proteoglycans, cell differentiation, proliferation and angiogenesis.
  • the hyaluronic acid is a considerably hydrophilic polysaccharide and is soluble in water in the form of a salt in the whole range of pH.
  • TEMPO is a relatively stable radical which can exist in reaction in three redox forms. Only the oxidized form of TEMPO is effective for alcohols or geminal diols oxidation.
  • a catalytic amount of TEMPO is added to the reaction and therefore, it is necessary to use a co-oxidant which restores the presence of the TEMPO oxidized form.
  • Oxidation of hyaluronan by use of TEMPO/NaClO system was described in the patent application WO 02/18448 A2. The authors also dealt with interactions of percarboxylated polysaccharides, while forming biological complexes.
  • the physico-chemical properties of the resulting hydrogels have been elucidated by instrumental analyses FT-IR, SEM (scanning electron microscopy) and rheometry. Increasing the oxidation degree of the hyaluronan lead to a corresponding increase of hydrogels compatibility and decrease of water absorption capacity. Dermal fibroblasts were used to study the cell-hydrogel interactions. Both the hydrogels and their degradation products are biocompatible, as proved by the long-term cell viability assay. When cultured with cells, the hydrogel underwent a degradation within 4 weeks, with an obvious loss of cohesiveness. The good biocompatibility and biodegradability was further demonstrated in mice subdermal implantations. Lastly, in vitro and in vivo depositions of extracellular matrix in hydrogels were demonstrated by SEM analysis.
  • the present invention relates to an improvement of a method of selective oxidation of the primary hydroxyl group of the hyaluronic acid in the position 6 of the polysaccharide glucosamine part to aldehyde.
  • the new reaction is performed using a system of 2,2,6,6- -tetramethyl-l-piperidinyloxyl radical TEMPO / co-oxidant.
  • Approaches published up to date have introduced either an aldehydic group to the position 2 and 3 of the hyaluronan glucuronic part, while opening the saccharide ring (scheme 6, structure 2), or a carboxyl group to the position 6 of the hyaluronan glucosamine part (scheme 6, structure 1).
  • the method according to the invention is more advantageous in that the respective oxidation product (structure 3, scheme 6) maintains the structure of conjugated saccharide rings. Ring opening in the product oxidized to dialdehyde (structure 2, scheme 6) gives rise to the chain linearity subreakage" and, therefore, a significant change of the polysaccharide 3- dimensional structure compared to the non-modified hyaluronan. Although in the product oxidized to a carboxylic acid (structure 1, scheme 6) the chain linearity impartbreakage" does not occur, the carboxyl group does not enable such various modification (binding) possibilities like the aldehydic group.
  • the prepared oxidized hyaluronan can be used for binding compounds containing for example an amino group.
  • the binding can be realized either in an imine form or after the reduction in an amine form (reductive amination) (scheme 7):
  • the modification of the hyaluronic acid derivative can be performed by a reaction of the oxidized derivative with an amine of the general formula H 2 N-R or with a hyaluronan substituted by an -R-NH 2 group, wherein R is an alkyl, linear or branched chain CI- C30, optionally containing aromatic or heteroaromatic groups.
  • This amine can be an alkylamine, e.g. butylamine or hexanediamine, amino acid, peptide or polysaccharide containing a free amino group.
  • cross-linked hyaluronan derivatives can be prepared.
  • the cross-linked derivatives can be prepared also by the reaction of an aldehyde with a hyaluronan substituted by an aminoalkyl group HA-alkyl-NH 2 .
  • Example 8 Oxidation of the hyaluronic acid by the TEMPO/TCC system
  • TEMPO (0.01 eq) and TCC (0.2 eq) were added to a hyaluronic acid solution (1%) (O.lg, 20 kDa) in the mixture of DMF/water 70/30. The mixture was stirred for 100 hours at the temperature of -5°C. The solution was then diluted to 0.1 % and dialyzed against the mixture (0.1% NaCl, 0.1% NaHC0 3 ) 3 x 5 liters (once per day) and against distilled water 7 x 5 liters (twice per day). The resulting solution was evaporated and analyzed.
  • the solution was then mixed with NaBH 3 CN (3 eq) in 0.5 ml of water. The mixture was stirred for 24 hours at the temperature of 20°C. The solution was then diluted to 0.1% and dialyzed against the mixture (0.1% NaCl, 0.1% NaHC0 3 ) 3 x 5 liters (once per day) and against distilled water 7 x 5 liters (twice per day). The resulting solution was evaporated and analyzed.
  • the resulting solution was diluted to 0.1% and dialyzed against the mixture (0.1% NaCI, 0.1% NaHC0 3 ) 3 x 5 liters (once per day) and against distilled water 7 x 5 liters (twice per day). The resulting solution was then evaporated and analyzed.
