    Design and development of novel herbal suppository formulation for prostatitis treatment
    (Igor Sikorsky Kyiv Polytechnic Institute, 2024) Golembiovska, O.; Dmytrenko, O.; Galkin, A.
    Background. Prostatitis is a common inflammatory condition of the prostate gland, often treated with antibiotics and anti-inflammatory drugs, which may have limited efficacy and side effects. Herbal therapies offer a promising alternative due to their natural anti-inflammatory properties. Objective. This study aims to design, develop, and evaluate physicochemical, biopharmaceutical and microbiological properties of novel herbal suppository formulations for the treatment of prostatitis, optimizing their biopharmaceutical profiles. Methods. Excipients were selected to form suppositories with herbal ingredients known for their antiinflammatory effects, specifically lovage, saw palmetto, and calendula CO2 extracts. The formulations were assessed based on key quality parameters, including organoleptic characteristics, average mass, melting point, deformation time, disintegration time, microbiological purity, and pH, ensuring compliance with European Pharmacopoeia (Ph. Eur.) standards. Biopharmaceutical studies compared the release profiles of active compounds from different suppository bases. Results. Suppositories based on Witepsol® H15 exhibited satisfactory organoleptic properties, appropriate melting points, and acceptable deformation and disintegration times. The pH levels were within the required range, and microbiological tests confirmed purity. Biopharmaceutical evaluations showed that Witepsol® H15 suppositories had the most appropriate release rates of active compounds compared to those made with other bases. Conclusions. The novel herbal suppositories developed in this study show promise for managing prostatitis based on preliminary evaluations of their physicochemical, microbiological, and biopharmaceutical properties. Further clinical studies are required to confirm their efficacy and safety.

    The influence of flavonoid compositions on Nrf2 transcription factor expression in case of infections triggered by influenza a virus and transmissible gastroenteritis coronavirus
    (Igor Sikorsky Kyiv Polytechnic Institute, 2023) Arkhypova, М.; Deriabin, О.; Trokhymchuk, Т.; Starosyla, D.; Atamaniuk, V.; Zavelevich, М.; Vialykh, Zh.; Rybalko, S.; Galkin, A.
    Background. Viral infections trigger transcription factors, including Nrf2, which regulate the expression of genes related to cytokines, chemokines, and more. Nuclear factor erythroid 2-related factor 2 (Nrf2) participates in complex regulatory networks controlling the expression of cytoprotective genes and immune responses. Recently, new roles have been attributed to Nrf2, including the regulation of antiviral responses. Objective. The aim of the study was to analyze Nrf2 activation in influenza virus infection in vivo and in transmissible gastroenteritis coronavirus (TGEV) infection in vitro, as well as the effects of the flavonoid compositions Proteflazidum and Protoil on the Nrf2 expression in these two experimental models of viral infection. Methods. Outbred white mice were infected with influenza A virus (A/FM/1/47/H1N1 strain). Jurkat cells were infected with TGEV, previously adapted to these cells. Flavonoid compositions Proteflazidum and Protoil (Ecopharm, Ukraine), containing the mixture of tricin, luteolin, apigenin, quercetin, and rhamnosin, were used in corresponding dilutions. Real-Time PCR was employed to analyze Nrf2 RNA expression in the lungs of mice and in both uninfected and virus-infected cells. Additionally, ELISA was used to assess the expression of Nrf2 peptide. Results. The Nrf2 expression in the lungs of influenza virus-infected mice showed a tendency to increase within a 100-fold range. In virus-infected mice treated with Proteflazidum or Protoil, the level of Nrf2 expression in the lungs decreased about 10-fold compared to infected untreated mice. TGEV infection resulted in 100-fold increase in Nrf2 expression in Jurkat cells. Both Proteflazidum and Protoil decreased Nrf2 expression in TGEV-infected cells, while their effects on Nrf2 expression in the intact cells on Day 1 were not detected. Conclusions. Flavonoid compositions have only a slight effect on Nrf2 expression in intact cells. However, in case of virus infection, both in vivo and in vitro, they counteract the extensive up-regulation of Nrf2 expression due to viral infection.
