(57) Abstract:

The invention relates to new biologically active chemical compounds, derived pyrazine formula I listed in the description, which is obtained by the interaction of the previously obtained through collaboration pyrazinamide with Amida sodium in liquid ammonia Na-salt pyrazin-2-carboxamide and 6-methyl-5-uracil sulfochloride in liquid ammonia. The substance is practically non-toxic (LD50in the acute experience 2350-8000 mg/kg). Shows anti-TB activity higher than pyrazinamide, high-leprosy activity, and high immunostimulatory effect in a wide range of doses. Can be used as medicines for the treatment of leprosy and tuberculosis, and as immunomodulators. 2 C. p. F.-ly, 3 tables.

The invention relates to new biologically active chemical compound sulfonylurea derived pyrazin-2-carboxamide

< / BR>
showing leprosy, TB and immunotropic activity, and how to obtain it.

Known structural analogue of pyrazinamide refers to PROTIVOTUBERKULEZNYI drug I series and own almost never used the volumes of tuberculosis, 1984, No. 7, S. 56 63/.

Counterparts in action diazipan and diaminodiphenylsulfone (DDS) are only leprosy activity. (Mashkovsky M. D. drugs, 1987, T. 2, S. 330).

The aim of the invention is the synthesis of new derivatives of pyrazinamide with a broader spectrum of action and is less toxic.

This goal is achieved by the compound of formula I with high leprosy, TB and immunotropic activity.

The specified connection is produced by interaction equimolecular quantities of Na-salt of amide pyrazinecarboxamide acid and 6-methyluracil-5-sulfochloride in liquid ammonia.

This connection cannot be obtained in the usual way, namely by the interaction of the corresponding amide and sulfochloride in an aprotic solvent in the presence of bases.

The toxicity of compound I was determined to outbred mice weighing 18 to 20 g in the acute experience of the method of Litchfield-Wilcoxon signed and amounted to more than 8000 mg/kg

The invention is illustrated by the following examples.

Example 1. N-(6-methyl-2,4-dioxo-1,2,3-tetrahydropyrimidine-5-sulfonyl)pyrazin-2-carboxamide (I).

In the slurry, 0.035 mol A0,035 mol) of 6-methyl-5-brazilbulgaria and stirred for further one hour. Evaporate the ammonia in a stream of ammonia and to the resulting solid residue is poured 100 ml of cold water. Nerastvorim precipitate is filtered off, washed on the filter with cold water, air-dried. Get to 7.15 g (84%) of white crystals with a melting point of 283 284oC (from dimethylformamide). Found, C of 38.7; H 2,71; S 10,1; N 22,8; C10H9N5O5S. Calculated, C And 38.6; H 2,9; S 10,3; N 22,5.

IR-spectrum (in petrolatum)c=1680, 1730 cm-1, 1400 cm-1, 1180 cm-1,NH1520 cm-1.

Example 2. The definition of leprosy activity.

Leprosy activity of compounds 1 was studied in 75 mice CBAxC57BI infected 5000 bacilli sulfonation strain of leprosy entered in the ball of the foot according to the method of Shepard.

Animals were treated with 7.5 months from the date of infection. Compound I was administered 5 times per week in the form of starch suspension (0.5 ml) inside through the probe at a dose of 50 μg/mouse.

The control group of animals infected at the same time the same quantity of the pathogen, were kept in the same conditions with an experienced and got inside through the probe only 0.5 ml of starch.

Another 3 groups of mice infected oppo

After 7.5 months, all animals were killed and held microscopy counting of Mycobacterium leprosy in each foot mouse in all groups of animals. The results obtained are presented in table 1.

Thus, animals treated with compound I, by the end of the experience bacilli of leprosy were not detected, that is, the preparation exhibits bactericidal activity.

Example 3. The definition of leprosy activity.

Antituberculosis activity of compound I in comparison with pyrazinamide and orotate pyrazinamide was determined under cultivation of Mycobacterium tuberculosis in liquid medium Shkolnikova with 10% human plasma.

To each tube containing 2 ml of medium with the test substance and different concentrations, were seeded with 0.2 ml of a suspension of Mycobacterium tuberculosis strains of "Academia", prepared by bacterial the turbidity standard No. 5 and diluted 10 times. Incubated for 10 days at 30oC. the Minimum inhibitory concentration was determined by the absence of colonies of Mycobacterium tuberculosis in vitro with the lowest concentration. To this end did the smear was stained by Zn, watched with increasing h about 100 fields of view.

Data analysis table 2 shows that in equitoxic doses of compound I compared to pyrazinamide and its oradata has a more pronounced anti-TB activity.

Example 4. The study of immunotropic activity of compound I.

Immunotropic activity of compounds was determined in comparison with Deuteronomy and oradata pyrazinamide. In the experiments used 280 mice hybrids (CBAxC57BI/6)F1, which were immunized intraperitoneally suboptimal dose of sheep erythrocytes (5106and immediately after this was introduced once the connection I, orotate pyrazinamide and diazepan oral in starch suspension. The substance is studied in a wide range of doses. In the control group changed only when starch suspension oral.

On the fourth day they were counting the number of the KLA in the spleens using local hemolysis in gel (method EPHE and Nordin). The index of stimulation of the immune response was calculated as the ratio of the KLA in the spleens of mice that received the drugs, including the KLA in the spleens of mice of the control group (see table. 3).

As can be seen from the table, compound I exhibits a high catalytic effect in all the tested doses and more efficient than diazepan is in: practically non-toxic, manifests bactericidal and leprosy activity; TB action in equitoxic doses higher than that of pyrazinamide and its orotata; highest immunostimulating effect in a wide range of doses in contrast to dialtone and orotata pyrazinamide.
