Effect of Pegylated Hyaluronate-Endo-β-N-Acetylhexosaminidase on Humoral Mechanisms Regulating the Functions of Progenitor Cells during Chronic Hepatitis

Hyaluronidase is an enzyme that helps maintain an optimal balance of hyaluronic acid in connective tissue and ensures full tissue regeneration. Currently, hyaluronidase drugs are used in various fields of medicine. Meanwhile, there are no oral preparations based on hyaluronidase on the pharmaceutical market due to its low bioavailability in this method of administration. One of the options to increase enzyme bioavailability is electron-beam pegylation, which involves obtaining drugs with a modified pharmacokinetic profile in the direction of increasing enteral bioavailability, as well as having additional protection from the action of proteolytic enzymes. Aim of the study was using the electron beam pegylation method to obtain a laboratory batch of a preparation based on highly purified hyaluronidase, which can be further used in the development of an oral drug product. Material and methods. Hyaluronidase, which was isolated from bovine testicular hyaluronidase and polyethylene glycols of different molecular weight, was used in the experimental study. Experiments were carried out using a pulsed linear accelerator ILU-10 for enzyme electron beam immobilization on a water-soluble polymer matrix of polyethylene glycol molecules. The formation of hyaluronidase and polyethylene glycols conjugates was confirmed by exclusion chromatography. Results. As a result of accelerated electron irradiation of hyaluronidase and polyethylene glycol of molecular mass 1500 Da conjugates of enzyme and polymer matrix were formed. After electron-beam pegylation, the specific activity of the enzyme was retained. Conclusions. A laboratory batch of prototype pharmaceutical substance based on immobilised hyaluronidase on polyethylene glycol was obtained.
