The invention relates to the field of organic chemistry, new biologically active substances of class 4-aryl-2-hydroxy-4-oxo-2-butenoate of heterylamine, namely 2-hydroxy-4-oxo-4-phenyl-2-butenoate of benzothiazolinone (1) of the formula

having hypoglycemic activity, suggesting its use in medicine as hypoglycemic agents.

The closest analogue to the structure of the claimed compound is 2-hydroxy-4-oxo-4-phenyl-2-butenoate 1,3,4-thiadiazolidine (2) [Synthesis and biological activity of salts of heterocyclic amines and heterylamides on the basis of 4-aryl-2, 4-dioxobutane acids/ Naulin., Was, USB [and other] // problems of biological, medical and pharmaceutical chemistry. - 2008. No. 2. - P.37-40] formula

Structural analogue of 2 does not possess hypoglycemic activity. A benchmark comparison of selected Metformin (3), which is widely used in medical practice and is similar in action [Mashkovsky PPM Medicines. - 15-ed., Rev., Corr. and extra - M.: OOO "New wave", 2005. - Vol.2. - S-563].

Object of the invention is the finding in a series of 4-aryl-2-hydroxy-4-oxo-2-butenoate of heterylamine substances with pronounced hypoglycemic activity and low toxicity.

Fasting is certain objective is achieved by obtaining 2-hydroxy-4-oxo-4-phenyl-2-butenoate of benzothiazolinone (1), having hypoglycemic activity.

The claimed compound 1 synthesized by the interaction of 2-hydroxy-4-oxo-4-phenyl-2-butenova acid (4) with 2-aminobenzothiazole in anhydrous chloroform at equimolar ratio of the reactants, at a temperature of 20-25°C, followed by separation of the target product with known methods using the pattern

An example of retrieving the connection 1. To a solution of 1.5 g (0.01 mol) 2-amino-benzothiazole in 25 ml of anhydrous chloroform was added a suspension of 1.92 g (0.01 mol) of 4-phenyl-2-hydroxy-4-oxo-2-butenova acid (2) in 20 ml of the same solvent. The reaction mixture is stirred at 20-25°C for two hours to dissolve the reagent. The solution is incubated 24 h, the reaction mixture was cooled to 0°C, the precipitation is filtered off, recrystallized from ethyl alcohol. Yield 3.28 g (92%). TPL 160-162°C. Found, %: C 59.72; H 4.28; N, 8.06. C17H14N2O4S. Calculated, %: 59.64%; N, 4.12%; N, 8.18%.

IR-spectrum (Specord M80, vaseline oil, ν, cm-1): S (N+H3HE), 1680 (C1=0), 1645, 1605 (C4=0, C=N, C=C). An NMR spectrum1N (BS-567A (100 MHz), DMSO-d6, GMDS, δ, ppm): 6.98 (1H, CH), 7.04-7.99 m (13H, WITH6H5With6H4, NH3).

The claimed compound 1 is a colorless crystalline substance, soluble in water, alcohol Adilov is m, dioxane, sparingly soluble in chloroform.

The hypoglycemic activity of compound 1 was studied on the model of alloxan diabetes. Experiments were performed on outbred rats of both sexes weighing 180-200 g Experimental hyperglycemia was modeled with subcutaneous injection of alloxan at a dose of 170 mg/kg Compound 1 was administered orally to rats with alloxan diabetes in a dose of 50 mg/kg as a suspension in 2% starch solution. Control animals were injected equiano amount of 2% starch solution. The concentration of glucose in the blood of animals was determined by glucose oxydase method [Cuhna SI, Slavnov V.N., Panchenko NI and other Functional methods of research in endocrinology. - Kiev: "Health", 1981. - P.61-64]. Rats were deprived of food for 16 hours before the experiment and at the time of the meeting. The degree of hypoglycemic activity of compound 1 and compound-standard (Metformin at a dose of 50 mg/kg) was determined after 120 minutes after their introduction. In addition, comparing the toxicity of the compounds and the comparison drug.

The results were processed statistically with the definition of student test using statistical software Windows XP (Excel).

Acute toxicity of the claimed compounds 1 by oral administration was studied on white mice of both sexes weighing 18-20 g with the definition of LD50[HOWTO for the study of General toxic is Astia pharmacological substances // Guidance on experimental (preclinical) study of new pharmacological substances./Under the General editorship of Corr-Corr. Russian Academy of medical Sciences, Professor Rugarama. - 2-ed., Rev. and supplementary): JSC "Publishing house "Science", 2005 - P.41-54]. In each series of 6 animals were used. The monitoring was conducted every hour within one day after administration of compound 1 in the form of a suspension in 2% starch solution. Control animals were injected equiano amount of 2% starch solution. The results were processed by Prozorovsky calculation of the median lethal dose (LD50) at P=0.05 [Prozorovsky V.B. have been, Prozorovsky BTW, Demchenko VI // Pharmacology and toxicology. - 1978. No. 4. - S-502].

Found that LD50connection 1 is 4500 mg/kg According to the classification of the toxicity of preparations of compound 1 belongs to the class of low-toxic substances [Izmerov IVAN, Sanotski I., Sidorov, K.K. Settings toxicometric industrial poisons. M.: Medicine, 1977, s-197].

As can be seen from the table, the compound 1 showed hypoglycemic activity on the model of alloxan diabetes and it is not inferior in effect to Metformin. While the claimed substance 1 3.5 times less toxic than the comparator drug.

Thus, 2-hydroxy-4-oxo-4-phenyl-2-butenoate of benzothiazolinone (1) shows high hypoglycemic activity and has far less toxic the STU in comparison with Metformin, what makes possible its use in medicine for the development of new drugs with hypoglycemic activity.
