Psoriasis affects about2To of population In 30-40% of occurrences arthropathic
psoriasis (AP) is diagnosed and it leads to 11-19% of disability cases development. The article analyses features of
anamnesis, clinical, instrumental and laboratory tests related to arthropathic psoriasis, considers the relationship of
probable mechanisms of disease aggravation and progression with the definition of a treatment method
influencing the dynamics of a disease course.
The objective of our work was to improve the diagnostics of AP patients taking into account some indicators of
the inrmune-epdocrine system and features of the disease course to specify their role in AP pathogenests and to
develop the system of integrated therapy of patients whose locomotor system is affected due to psoriasis

Heterocycles are commonly known for their unique features, e.g., antibacterial or anticancer properties. Although many synthetic heterocycles, such as 4-thiazolidinone (4-TZD), have been synthesized, their potential applications have not yet been fully investigated. However, many researchers have reported relevant results that can be a basis for the search for new potential drugs. Therefore, the aim of this study was to evaluate the cytotoxic, cytostatic, and antibacterial effects of certain 4-thiazolidinone-based derivatives, Les-3166, Les-5935, Les-6009, and Les-6166, on human fibroblasts (BJ), neuroblastoma (SH-SY5Y), epithelial lung carcinoma (A549), and colorectal adenocarcinoma (CACO-2) cell lines in vitro. All tested compounds applied in a concentration range from 10 to 100 µM were able to decrease metabolic activity in the BJ, A549, and SH-SY5Y cell lines. However, the action of Les-3166 was mainly based on the ROS-independent pathway, similarly to Les-6009. In turn, Les-5935 and Les-6166 were able to promote ROS production in BJ, A549, and SH-SY5Y cells, compared to the control. Les-3166, Les-6009, and Les-6166 significantly increased the caspase-3 activity, especially at the concentrations of 50 µM and 100 µM. However, Les-5935 did not induce apoptosis. Only Les-5935 showed a minor cytostatic effect on SH-SY5Y cells. Additionally, the antibacterial properties of the tested compounds against P. aeruginosa bacterial biofilm can be ranked as follows: Les-3166 > Les-5935 > Les-6009. Les-6166 did not show any anti-biofilm activity. In summary, the study showed that Les-5935, Les-6009, and Les-6166 were characterized by anticancer properties, especially in the human lung cancer cell. In cases of BJ, SH-SY5Y, and CACO-2 cells the anticancer usage of such compounds is limited due to effect visible only at 50 and 100 µM.

Tlre possible role of viral persistence as an epigenetic factor in the development of
psoriasis is discussed when a specific antigen (virus, especially type 1,2 (HSV 1,2)) is considered as a trigger factor
for direct or indirect action on immunocompetent cells.
The purposeTo evaluate the peculiarities of blood lyrnphocytes phenotyping in patients with psoriasis and
activated chronic Herpes slmplex virus infection compared to patients with psoriasis, activated chronic Herpes
virus infection, and healthy persons during treatment

Synthesis and study of new polyfunctionalized 2-hydrazinoanthraquinone derivatives as potential antimicrobial agents. Methods. Organic synthesis, NMR and LC-MS spectroscopy, agar diffusion and broth microdilution methods. Results. A series of anthraquinonehydrazone derivatives are synthesized using the reaction of 2-(morpholinodiazenyl)anthracene-9,10-dione with methylene active compounds in the acetic acid medium. The screening of antimicrobial activity identified the compounds with significant effects against the tested microorganisms with MIC value <186.9 μM. Compounds 5 and 11 with MIC <93.5 μM are effective against yeast fungi whereas compound 5 with MIC <186.9 μM is effective against P.putida, which is multidrug resistant to antibiotics.
