Aim. Synthesis and study in vivo of acute toxicity, anti-inflammatory (anti-exudative) activity and evaluation of side effects of pyrazoline-thiazolidin-4-one hybrid Les-5581 under conditions of therapeutic use in experimental animals. Methods. Traditional organic synthesis. The Litchfield - Wilcoxon method. Carrageenin- and formaldehyde-induced inflammatory paw edema models of white rats. Clinical laboratory tests: study of general blood parameters and biochemical profile of liver function (ALT, AST, LF and γ-GGT levels). Evaluation of ulcerogenic action. Results. The target hybrid Les-5581 has been synthesized in convenient and efficient aminolysis of 5-etoxymethylidenerhodanine by 3,5-bis-(4-chloro-phenyl)-4,5-dihydro-1H-pyrazole. The LD50 value for Les-5581 was determined with intraperitoneal use and it was 510 mg/kg. The Les-5581 exhibits significant anti-inflammatory activity at a dose of 50 mg/kg (intraperitoneal use) in [the] experiment on carrageenin- and formaldehyde-induced inflammatory models in white rats. At the same time, the use of Les-5581 does not provoke a negative impact on the blood pattern, the liver enzymes function and has no ulcerogenic effect. Conclusions. The pyrazoline-thiazolidine-4-one hybrid Les-5581 is a good molecular platform for the development of new potential low-toxicity anti-inflammatory drugs without ulcerogenic action.
