Rheological study of hyaluronic acid derivatives

The viscoelastic properties of four novel, lowmolecular weight hyaluronic acid derivatives were investigatedand compared to the parent hyaluronic acid compound. Briefly, all derivatives were synthesized by firstdeacetylating the parent hyaluronic acid. One sample wasleft as such, while two others were reacytelated. The finalcompound, of particular interest for its anti-inflammatoryproperties, was butyrylated. The compounds were dissolvedin phosphate buffer solution (PBS) and studied at aconcentration of 5 mg/mL. Shear thinning behaviour wasobserved for all compounds, however, derivative sampleshad a lower viscosity than the parent compound at highshear rates. Viscoelastic properties were also observed todecrease as a result of the derivative preparation method. Itis believed that these changes are primarily caused by adecrease in hyaluronic acid molecular weight. Byincreasing the concentration of the anti-inflammatorycompound, it may be possible to modulate the viscoelasticproperties to more closely resemble those of commercialviscosupplements. As a result, an anti-inflammatoryderivative of hyaluronic acid may potentially improve uponexisting viscosupplements used to treat patients who aresusceptible to flare up.
