Due to the property of reducing lipids, these compounds can be used for the treatment and prophylaxis of diseases in humans caused by blood cholesterol and / or blood triglycerides (cardiovascular diseases, thrombosis, atherosclerosis, myocardial infarction, as well as stenocardi). The properties of the compounds of formula I are confirmed by laboratory tests, in animal experiments, of mammals such as guinea pigs, mice, rats, cats, dogs, or monkeys. The compounds can be administered enterally or parenterally, and in the treatment of humans, orally. The following tests, in particular, were used to study the lipid-lowering properties of the compounds of formula I. The test substances were suspended in freshly prepared 1% carboxymethylcellulose and injected intraperitoneally to MbmiaM males (strain: OF 1, Switzerland, SPF, the weight at the beginning of the test was about 25 g) drinking water once a day in the same doses (20 mg / kg with a constant volume of 10 ml / kg) for 14 days. The control group received only 10 cells / kg of 1% carboxymethylcellulose; 4 hours after the last intake of the test substances or carboxymethylcellu oza of animals in the control Five groups were killed by bleeding through Aorta carotis. EDTA (ethylenediaminetetraacetic acid) plasma was used to determine the level of blood lipids in experimental animals. Q Methods of analysis. Cholesterol was determined both by the classic fy (Liberman-Burchard staining) and by the full enzymatic method (Tselekhrom cholesterine; test system: Cheniie Linz AG, diagnostics; Linz, Austria). Triglycerides were determined according to the fully enzymatic method (triglycerides of iodonitrotetrazolineunislets P1, test system: Chemie Linz AG, diagnosis} Linz, Austria). In tests, compounds of general formula I showed strong low-reducing properties. Hanpm tep, 2, 3-dihydro-3-oxothieno- (3, A-d) -1,2-thiazole-propionic acid-1-1 dioxide at a dose of 20 mg / kg i, p. a 9.2% reduction in cholesterol and a 7.8% reduction in thieno-1,2-thiazole of the general formula I triglyceride level in the blood are observed in comparison with the control group of animals. Compounds of general formula I can be used as therapeutic agents, for example pharmaceutical preparations, js which contain them in mixture with pharmaceuticals suitable for enteral or parenteral administration, organic or inorganic inert auxiliary and / or carrier materials, for example pharmaceutically suitable solvents, gelatin, gum arabic, milk sugar, starch, magnesium stearate, talc, vegetable oils, poly (25) alkylene glycols, petroleum jelly, and the like. Pharmaceutical preparations can be prepared in solid form, for example, in tablets, dragees, suppositories, capsules, as well as in the form of solutions of suspension or emulsions. If necessary, these drugs are sterilized, additives are added (preservatives, stabilizers or emulsifiers), salts to change the osmotic pressure, as well as other therapeutic agent compounds, which are of low toxicity making them promising in the creation of drugs used in medicine.
