PRECLINICAL INVESTIGATION OF THE ALLERGENIC EFFECT OF THE DRUG BASED ON THE PHENOLIC COMPOUND KUD975

Introduction: Vascular endothelium is a cellular monolayer that covers the internal lumen of all blood vessels, thus separating blood from the vessel wall and tissues. The study of the role of endothelium in the pathogenesis of cardiovascular diseases led to an understanding of the concept of it as a target for the prevention and treatment of these pathologies. Research tasks: The purpose of this study was preclinical study of the allergic effect of the drug KUD975, based on a phenolic compound, which is a selective inhibitor of arginase 2. Methods: Experiments on the allergic properties of the phenolic compound KUD975, which is a selective inhibitor of arginase II, were carried out on albino sexually mature guinea pigs weighing 300 ± 20 g. The preparation was administered intragastrically as a suspension in a 1% starch paste using a specially prepared atraumatic probe at 0, 1 ml of suspension per 10 g of body weight of animals. As a control, we used data obtained in animals with intragastric administration of the corresponding volume of placebo-1% starch paste. Results: In the course of the study of the allergic properties of KUD975, when the reaction of active cutaneous anaphylaxis was formulated, it was found that the studied preparation in two and eight times daily therapeutic dosages did not possess allergic properties In the course of the study of the allergic properties of KUD975 in the formulation of a delayed-type hypersensitivity reaction, it was found that the study drug in two and eight times daily therapeutic dosages had no allergenic properties. Erythema, or, especially, infiltration and the appearance of ulcers at the site of administration as a resolving dose of the drug, as well as in the control of reactivity, were not observed in any animal participating in the experiment. Conclusion: When investigating the allergenic properties of the phenolic compound KUD975, which is a selective inhibitor of arginase II in the reaction of active cutaneous anaphylaxis, it was found that the study preparation in two and eight times daily therapeutic dosages does not have allergic properties. In the reaction of active cutaneous anaphylaxis in guinea pigs, the allergic properties of KUD975 in two and eight times daily therapeutic dosages were not detected Key words: compounds of phenolic nature, allergic action, endothelium, inhibitors of arginase II
