Description

(57) The invention relates to the field of pharmaceutical industry and medicine. The objective of the invention is the creation of an effective pharmaceutical composition with neuroprotective, antiamnestic, antioxidant, antihypoxic, antiischemic activity. The problem is solved due to the fact that the pharmaceutical composition contains 2-ethyl-b-methyl-3-hydroxypyridine succinate, the peptide MsG-SPi-ELK-RNs-Rgo-SPu-Rgo and differs from the prototype in that it additionally contains minerals: potassium , magnesium, iron. In addition, in the pharmaceutical composition, part of the carbon isotopes ¹² C is replaced by carbon isotopes ¹³ C. The technical results of the invention are: an increase in the onset of the therapeutic effect, an increase in the therapeutic effect without increasing the concentration of 2-ethyl-b-methyl-3-hydroxypyridine succinate and Me1 -S1i-H15-Pb-Rgo-S1u-Rgo, increasing stability over the expiration date.

FIELD OF THE INVENTION

The invention relates to the pharmaceutical industry and medicine and can be used in the manufacture and use of pharmaceutical compositions with a polypeptide sequence Me1-O1i-NT8-Pb-Rgo-O1u-Rgo, which have neuroprotective, antiamnestic, antioxidant, antihypoxic, neurometabolic, anti-ischemic activity.

State of the art

An important problem of modern medicine is the creation of new drugs that can effectively protect and also treat brain diseases.

An effective area of research in this area is the creation of new drugs based on methionyl-glutamyl-histidyl-phenylalanyl-prolyl-glycyl-proline (hereinafter, semax) and ethylmethylhydroxypyridine succinate (hereinafter, mexidol) preparations.

Semax is a drug that effectively affects the processes associated with the formation of memory and learning, improves mnemonic functions, improves the adaptation of the human body to hypoxia, cerebral ischemia, anesthesia and other damaging effects. In other words, semax improves the energy processes of the brain, increasing its resistance to stress damage, hypoxia. Semax is a good nootropic, neurometabolic stimulant.

In turn, Mexidol has a mechanism of action, the fundamental difference from the mechanism of action of traditional neuropsychotropic drugs is its lack of specific binding to known receptors (Research Institute of Pharmacology RAMS, T.A. Voronin. Mexidol. Main effects, mechanism of action, application (1 Шр: //\у\u\u.uoeb.gi/te\1bo1.1Ts)). Mexidol is an inhibitor of free radical processes, lipid peroxidation, it activates superoxide dismutase, affects the physicochemical properties of the membrane, increases the content of polar lipid fractions (phosphotidylserine and phosphotidylinositol, etc.) in the membrane, reduces the ratio of cholesterol / phospholipids, reduces the viscosity of lipid layer and increases the fluidity of the membrane, activates the energy synthesizing functions of mitochondria and improves energy metabolism in the cell and, thus, protects the apparatus of cells and the structure of their membranes.

The change in the functional activity of the biological membrane caused by mexidol leads to conformational changes in the protein macromolecules of synaptic membranes, as a result of which mexidol has a modulating effect on the activity of membrane-bound enzymes, ion channels and receptor complexes, in particular benzodiazepine, G AMA, acetylcholine, enhancing their ability to bind to the ligand increasing the activity of neurotransmitters and activation of synaptic processes. Along with this, Mexidol has a pronounced lipid-lowering effect, reduces the level of total cholesterol and low density lipoproteins and increases high density lipoproteins.

Thus, the mechanism of action of Mexidol is determined primarily by its antioxidant properties: the ability to stabilize cell biomembranes, activate the energy synthesizing functions of mitochondria, modulate the activity of receptor complexes and the passage of ion currents, enhance the binding of endogenous substances, improve synaptic transmission and the relationship of brain structures. Due to this mechanism of action, Mexidol affects the key basic links in the pathogenesis of various diseases, has a wide range of effects, extremely small side effects and low toxicity, and has the ability to potentiate the action of other centrally acting substances, especially those that realize their action as direct receptor agonists.

The invention provides two variants of the pharmaceutical composition. Each of the claimed pharmaceutical compositions has, as active substances, a polypeptide sequence of Me1-O1i-H18-Pbe-Pro-O1y-Pro and 2-ethyl-6-methyl-3-hydroxypyridine succinate.

Below are analogues that describe the polypeptide sequence Me1-O1c-H18-Pb-Pro-O1y-Pro and 2-ethyl-6-methyl-3-hydroxypyridine succinate.

An analogue of each variant of the pharmaceutical composition is a pharmaceutical composition for the treatment of ischemic stroke, containing the polypeptide sequence Me1-O1c-H18-Pb-Rgo-O1u-Rgo (patent for the invention of the Russian Federation No. 2251429, publ. July 27, 2004).

The disadvantage of the analogue is the relatively low speed of the onset of the therapeutic effect.

In addition, there is an analogue - RF patent No. 2156087, publ. 09/20/2000. The patent describes a biologically active food supplement (BAA), including potassium, manganese, zinc, iron and an additional 29 different substances. The patent claims that the dietary supplement has antihypoxic and antioxidant properties.

The disadvantage of the analogue is the impossibility of its use for medicinal purposes.

It is known the use of Semax as a neuroprotector (patent for the invention of the Russian Federation No. 2394816, publ. 20.07.2010). In the patent of the Russian Federation No. 2394816 in the table. Figure 7 shows the change in neurological deficit in rats after bilateral ligation of the common carotid arteries under the influence of Semax, Mexidol, and Amtizol preparations. The patent concludes that mexidol is more preferable, semax due to the lack of effectiveness of the latter and the impossibility of increasing its concentration in solution.

A known analogue (patent for the invention No. RF 2425670, publ. 08/10/2011). Semax and choline alfoscerate are used in the analogue. The drug choline alfoscerat increases the effectiveness of Semax.

It is known to use the semax peptide of the formula Me1-C1i-H15-Pb-Pe-C1u-Prgo as an antithrombotic, anticoagulant, fibrin-polymerization and fibrinolytic agent (RF patent No. 2290194, publ. 27.12.2006).

The disadvantage of the analogue is its relatively low effectiveness of the therapeutic effect.

It is known to use the polypeptide sequence Me1-C1i-H15-Pb-Rho-C1u-Rgo as a memory stimulant (AS USSR 939440, publ. 06/30/1982), which is the basis of a nootropic drug and a pharmaceutical composition of nootropic action (RF patent No. 2045958, C16 A61K 38/08, 1994).

The disadvantage of the analogue is the relatively low speed of the onset of the therapeutic effect.

Known patent application 2006146529, publ. 07/20/2008. The application describes a pharmaceutical composition having neurotropic, antiamnestic, antihypoxic and antiischemic activity. The composition as active ingredients contains semax and mexidol or their pharmaceutically acceptable salts in therapeutically effective amounts. Here, the effectiveness of Semax is enhanced by the use of Mexidol.

Also known patent EAPO 008591, publ. 06/29/2007. The patent proposes the use of derivatives of 3- (3,5-dioxo-4,5-dihydro-3H- (1,2,4) -triazin-2-yl) benzamide as P2X ₇ inhibitors for the treatment of various diseases, including ischemia with a stroke or heart attack. The patent provides for the use of isotopes ¹³ C, ¹⁵ Ν, etc. for making isotopic labels in a drug. The isotopes determine the dynamics of the distribution of the drug in the tissues of the body.

Another analogue of the pharmaceutical composition variants is an agent containing mexidol and excipients: potato starch, polyvinylpyrrolidone, magnesium stearic acid, microcrystalline cellulose, milk sugar (RF patent No. 2145855, publ. 26.05.1999). The drug is intended for the treatment of impaired brain functions, in particular acute and chronic cerebrovascular disorders.

The disadvantage of this analogue is the low stability of the pharmaceutical product over the expiration date.

Also analogous to all variants of the pharmaceutical composition is a stable pharmaceutical composition for injection containing Mexidol, succinic acid, Trilon B and water for injection (RF patent No. 2205640, publ. 09.04.2002). The drug is prescribed intravenously and intramuscularly.

The disadvantage of this analogue is the low stability of the pharmaceutical composition over the expiration date.

In addition, there is an analogue - RF patent No. 2156087, publ. 09/20/2000. The patent describes a biologically active food supplement, including potassium (4-380 mg / l), magnesium (1-510 mg / l), iron (1-2100 mg / l), zinc (1-1240 mg / l), Mexidol (1-200 mg / L) and an additional 29 different substances. The patent claims that the dietary supplement has antihypoxic and antioxidant properties.

The disadvantage of the analogue is the impossibility of its use as a composition for injection. Another disadvantage is the low content of Mexidol in 1 liter, about three orders of magnitude less than that required for the injection solution.

The prototype of the two variants of the invention is the pharmaceutical composition (application for the invention of the Russian Federation 2006146529/15, publ. 20.07.2008), with neuroprotective, antiamnestic, antioxidant, antihypoxic, neurometabolic, antiischemic activity, containing 2-ethyl-6-methyl-3-hydroxypyridine succinate as well as the polypeptide methionine-glutamistidine-phenylalanine-prolyl-glycine-proline (Me1-C1i-H15-Pb-Pe-Pro-C1u-Pro).

The objective of the prototype was to expand the arsenal of drugs with pronounced neuroprotective activity, in combination with antiamnestic, antioxidant, antihypoxic, neurometabolic, antiischemic activity.

Studies have shown that the prototype is not always effective in these pathologies. Another disadvantage of the prototype is the relatively low speed of the onset of the therapeutic effect.

Signs of the prototype Pharmaceutical composition with neuroprotective, antiamnestic, antioxidant, antihypoxic, neurometabolic, antiischemic activity, containing 2-ethyl-6-methyl-3-hydroxypyridine succinate, methionine-glutamistidine-phenylalanine-proline-glycine1 (proline-glycine-glycine polypeptide) H15-Pb-Rgo-O1y-Rgo) coincide with the features of the claimed variants of the invention.

In the prototype, a pharmaceutically acceptable solvent is water (distilled water or water for injection). A pharmaceutically acceptable excipient in the pharmaceutical composition is ammonium acetate.

The structural formula of the methionine-glutamine-histidine-phenylalanine-prolyl-glycine proline polypeptide (Ме1-С1и-Н15-Ре-Рго-С1у-Рго):

- 2,020,558

The formula of 2-ethyl-6-methyl-3-hydroxypyridine succinate can be represented as follows:

The N'-H bond is a covalent bond.

The above preparation contains a 2-ethyl-6-methyl-3-hydroxypyridine cation (2-ethyl-6-methyl-3hydroxypyridinium) and a pharmaceutically acceptable anion, namely C ₄ H ₆ O ₄ . The ionic bond between the cation and the anion is the bond between the negatively and positively charged particles in the preparation.

As the anion, not only succinate can be used, but also another substance, in particular chloride. Therefore, a wider formulation of features describing 2-ethyl-6-methyl-3-hydroxypyridinium may be as follows:

A pharmaceutical composition containing 2-ethyl-6-methyl-3-hydroxypyridinium and a pharmaceutically acceptable anion.

The disadvantages of the prototype are the relatively low speed of the onset of the therapeutic effect, the insufficiently large therapeutic effect of the pharmaceutical agent, the low stability of the pharmaceutical composition over the expiration date.

SUMMARY OF THE INVENTION

Let us define the terms.

Shelf life - the period during which the pharmaceutical composition retains its properties in a measure that ensures its intended use.

Neuroprotective activity of the pharmaceutical composition (drug) - stopping and limiting damage to brain tissue that develops as a result of acute ischemia (hypoxia).

The medicine activates metabolic processes in the brain, protects nerve cells from attacks of free radicals and toxins, as well as from other harmful effects.

Antiamnestic activity of the drug is a counteraction to amnesia.

Amnesia is a general or partial inability to recall recent or distant events.

The antioxidant activity of the drug is the ability to slow the oxidation of organic compounds.

Antihypoxic activity of the drug - improves utilization of oxygen circulating in the body and increases the body's resistance to hypoxia (oxygen deficiency). Hypoxia is a state of oxygen starvation due to impaired external and internal (tissue, cellular) respiration.

Neurometabolic activity - stimulates the synthesis and utilization of oxygen and glucose, increases ATP synthesis under conditions of ischemia and hypoxia by more than an order of magnitude.

Anti-ischemic activity of the drug - prevents local anemia, often due to a vascular factor (narrowing or complete obstruction of the lumen of the artery), leading to temporary dysfunction or permanent damage to the tissue or organ.

Ischemia is local anemia, often caused by a vascular factor (narrowing or complete obstruction of the lumen of the artery), leading to temporary dysfunction or permanent damage to the tissue or organ. The consequences of ischemia depend on the degree and rate of decrease in blood flow parameters, the duration of ischemia, tissue sensitivity to hypoxia, and the general condition of the body. The organs of the central nervous system and myocardium are the most sensitive to ischemia.

Ischemia has a number of significant differences from hypoxia.

Ischemia is characterized by relative or absolute insufficiency of blood supply, which is manifested not only by local tissue hypoxia, but also by other metabolic disorders due to insufficient intake of nutrients.

Ischemia is a dynamic and, as a rule, potentially reversible process. The likelihood of ischemic necrosis (heart attack) of the tissue directly depends on the duration and degree of decrease in local blood flow.

The myocardium is the muscle layer of the heart, which makes up its main mass. Built from a special striated muscle tissue, which is a tight connection of muscle cells. A functional feature of the myocardium is rhythmic automatic contractions, alternating with relaxation, occur continuously throughout the life of the body.

The objective of the present invention is to provide an effective pharmaceutical composition with neuroprotective, antiamnestic, antioxidant, antihypoxic, neurometabolic, antiischemic activity.

The problem is solved due to the fact that the pharmaceutical composition possessing neuroprotective, antiamnestic, antioxidant, antihypoxic, neurometabolic, antiischemic activity contains 2-ethyl-6-methyl-3-hydroxypyridine succinate, methionine-glutamistidine-phenylalanine-prolyl polypeptide (Ме1-О1и-Нг5-Ре-Рго-О1у-Рго) and differs from the prototype in that it additionally contains mineral substances in the following ratio of components, mg / l:

2-ethyl-6-methyl-3-hydroxypyridine succinate polypeptide methionine-glutamine-histidine phenylalanine-prolyl-glycine-proline potassium magnesium

0.4 10 ³ -300'10 ³

0.1-30 0.001 -158.0 0.0001 -70.3 iron 0.007-345

The problem is also solved due to the fact that the pharmaceutical composition having neuroprotective, antiamnestic, antioxidant, antihypoxic, neurometabolic, antiischemic activity contains 2-ethyl-6-methyl-3-hydroxypyridine succinate, methioninglutamine-histidine-phenylalanine-prolyl polypeptide proline (Me1-C1i-H15-Pb-Rgo-C1u-Rgo) and differs from the prototype in that it additionally contains mineral substances in the following ratio of components, mg / l:

2-ethyl-6-methyl-3-hydroxypyridine succinate polypeptide methionine-glutamine-histidine phenylalanine-prolyl-glycine-proline potassium magnesium

0.4 10 ³ -300'10 ³

0.1-30 0.001 -158.0 0.0001 -70.3 iron 0.007-345 while the pharmaceutical composition is made in such a way that it contains ¹³ C carbon isotopes, the ratio of ¹³ C carbon isotopes to the total amount of carbon in the pharmaceutical composition is 0.005-0.75.

The active ingredients in the pharmaceutical solution are the preparation of 2-ethyl-6-methyl-3-hydroxypyridine succinate and the methionine-glutamine-histidine-phenylalanine-prolyl-glycine proline polypeptide (Me1-C1i-H15-Pb-Rgo-C1u-Rgo).

The pharmaceutical composition is in the form of a solution, for example, in the form of a solution for injection. The pharmaceutical composition has a pH value of from 4 to 7.

The kinematic viscosity of the pharmaceutical composition in the form of a solution is 1.01-1.23 mm ² / s. The kinematic viscosity of the pharmaceutical composition is determined using a capillary viscometer.

Also, the pharmaceutical composition can be made in the form of nasal drops or a solution for oral administration (in particular, syrup, dietary supplement).

In the pharmaceutical composition, in addition to the active substances: the methionine-glutamingistidine-phenylalanine-prolyl-glycine-proline polypeptide (or its pharmaceutically acceptable salt), the preparation of 2-ethyl-6-methyl-3-hydroxypyridine succinate (or its pharmaceutically acceptable salt) and mineral substances, you can use a pharmaceutically acceptable solvent. In addition to the solvent, a pharmaceutically acceptable excipient or pharmaceutically acceptable excipients may be used in the pharmaceutical composition.

As a pharmaceutically acceptable solvent, water (distilled water) as well as another solvent may be used.

Ammonium acetate, sodium disulfate (sodium metabisulfate) or another pharmaceutically acceptable substance may be used as a pharmaceutically acceptable excipient.

In other words, the active ingredients are the basis of the pharmaceutical composition: the preparation of 2-ethyl-6-methyl-3-hydroxypyridine succinate, the methionine-glutamine-histidine-phenylalanine-prolyl-glycine-proline polypeptide (Me1-C1i-H15-Pb-Rgo-C1u-Rgo ) and minerals in a pharmaceutically acceptable solvent, in particular in water.

- 4,020,558

In the pharmaceutical composition, the active substances and minerals are selected from the above ranges, and the rest is up to 1 liter of solvent.

The technical results of the invention are:

an increase in the speed of the onset of the therapeutic effect (a decrease in the time of the onset of the therapeutic effect) while maintaining the duration of action without increasing the concentration of the methionine-glutamine-histidine-phenylalanine-prolyl-glycine-proline polypeptide (Me1-O1i-NT8-Pb-Rgo-O1u-Rgo) and the drug 2-ethyl-6-methyl-3-hydroxypyridine succinate in the treatment of disorders of the nervous system, ischemia and hypoxia of the central nervous system and myocardium, amnesia, as well as with an increase in the activity of the endogenous system and a decrease in the intensity of free radical percentages ess;

an increase in the therapeutic effect without an increase in the concentration of the methionine-gluthingistidine-phenylalanine-prolyl-glycine-proline polypeptide (Me1-C1i-H | 5-RNe-Rgo-C1u-Rgo) and the preparation of 2-ethyl-6-methyl-3-hydroxypyridine succinate when treatment of disorders of the nervous system, ischemia and hypoxia of the central nervous system and myocardium, amnesia, as well as an increase in the activity of the endogenous system and a decrease in the intensity of free radical processes;

increasing the stability of the pharmaceutical composition with a methionine-glutamististidine-phenylalanine-prolyl-glycine-proline polypeptide (Me1-C1i-H | 5-RNe-Rgo-C1u-Rgo) and 2-ethyl-6-methyl-3-hydroxypyridine succinate expiration date.

The lower limit of the content in the pharmaceutical composition of the methioninglutamine-histidine-phenylalanine-prolyl-glycine-proline polypeptide and the lower limit of the content in the pharmaceutical composition of 2-ethyl-6-methyl-3-hydroxypyridine succinate can be used to treat children and pregnant women, as well as as a part of dietary supplement.

The upper limit of the pharmaceutical composition of the polypeptide methioninglutamine-histidine-phenylalanine-prolyl-glycine-proline and the upper limit of the pharmaceutical composition of the drug 2-ethyl-6-methyl-3-hydroxypyridine succinate can be used to treat adults with severe stroke.

Pharmaceutical formulations with upper bounds for the methionine-glutamingistidine-phenylalanine-prolyl-glycine-proline polypeptide and the 2-ethyl-6-methyl-3-hydroxypyridine succinate preparation are concentrated formulations and may be diluted with a pharmaceutically acceptable solvent. Concentrated execution of pharmaceutical formulations is convenient during transportation and storage.

Currently, an increase in the speed of the onset of the therapeutic effect with the introduction of drugs into the body provides:

dosage of the drug and its exposure time;

introducing into the solution an auxiliary ingredient - an accelerator of the speed of exposure (a special case of a regulator of the speed of exposure).

Here are some examples.

A known solution (RF application No. 94015245, publ. 12/27/1995), in which a 5-10% solution of hyaluronic acid is used as a regulator of the speed of exposure.

Known pacemaker drug (RF patent No. 2068697, publ. 10.11.1996) containing green toad venom, chlorobutane dihydrate, sodium chloride and water. To increase the onset of the pacemaker effect (while maintaining the duration of action) provided by the specified poison, up to 95% ethyl alcohol is introduced into the drug. Alcohol due to osmotic phenomena causes pain and local negative reaction, which accelerates the effect of the drug.

Biologically active additives are known which, when introduced together with the active principle, increase the pharmacological activity of therapeutic drugs by optimizing the rate of assimilation of the active principle. So, polyvinylpyrrolidone and sorbic acid are additionally introduced into the antitumor agent (AS USSR 1683190, publ. 20.04.1995). These components increase the antitumor activity of the active principle.

In the invention, an increase in the speed of the onset of the therapeutic effect is achieved while maintaining the duration of action without increasing the concentration of the active substance in the pharmaceutical agent by introducing mineral substances into the pharmaceutical composition.

Studies have shown that the mineral substances that make up the preparations enhance their therapeutic effect. This is ensured mainly due to a pronounced irritating effect on body tissues, as well as by exposure to the enzymatic system of the body.

For all variants of pharmaceutical compositions considered in the invention, the rational ranges of mineral content values are as follows:

potassium 0.001 - 158.0 magnesium 0.0001 -70.3 iron 0.007 - 345

These ranges partially overlap with the ranges of mineral values in dietary supplements (see RF patent No. 2156087). The novelty of the invention is ensured through the use in the pharmaceutical composition of the polypeptide methionine-glutamine-histidine-phenylalanine-prolyl-glycine-proline (Me1-O1i-H18-Pb-Rgo-O1u-Progo).

When developing the invention it was found that an increase in the speed of the onset of the therapeutic effect, an increase in the therapeutic effect without increasing the concentration of the Me1-C1i-H | 5-RNe-Rgo-C1u-Rgo peptide and the drug 2-ethyl-6-methyl-3-hydroxypyridine succinate in the pharmaceutical composition, increasing the stability of the pharmaceutical composition with the Me1-C1i-H | 5-RNe-Rgo-C1u-Rgo peptide and the preparation of 2-ethyl-6-methyl-3-hydroxypyridine succinate over the shelf life are ensured by the introduction of certain minerals into the pharmaceutical composition (certain mineral combinations s) at a specific amount for each mineral. As a result of the studies, a weight range in the pharmaceutical composition was established for each mineral. The use of less than indicated in the range, the amount of mineral substance does not lead to the achievement of technical results. The use of a larger amount of mineral substance than indicated in the range not only does not lead to the achievement of technical results, but worsens the therapeutic effect of the action of the peptide Me1-O1i-H18-Rle-Rgo-O1u-Rgo and the preparation 2-ethyl-6-methyl- 3-hydroxypyridine succinate. It was found that with an increase in the concentration of minerals in the pharmaceutical composition (above the stated ranges), they suppress the action of the drug 2-ethyl-6-methyl-3-hydroxypyridine succinate and the peptide Me1-C1i-H | 5-RNe-Rgo-C1u-Rgo. the therapeutic effect of the drug disappears.

An additional increase in the speed of the onset of the therapeutic effect, an increase in the therapeutic effect without increasing the concentration of the Me1-C1i-H | 5-RNe-Rgo-C1u-Rgo peptide and the preparation of 2-ethyl-6-methyl-3-hydroxypyridine succinate in the pharmaceutical composition, increasing the stability of the pharmaceutical composition with the peptide Me1-C1i-H | 5-RNe-Rgo-C1u-Rgo and the preparation of 2-ethyl-6-methyl-3-hydroxypyridine succinate during the shelf life are partially replaced in the pharmaceutical composition of ¹² C carbon isotopes with ¹³ C carbon isotopes.

In another reactor with a stirrer (5 L volume), 4 L of water for injection is poured. Then, the preparation of 2-ethyl-6-methyl-3-hydroxypyridine succinate - 10,000 mg is loaded into this reactor and the solutions with minerals are poured with constant stirring. Then the resulting solutions are poured into the reactor with a stirrer, the pH of the solution is adjusted to a value of 4.5. The resulting solution was adjusted to a volume of 10 l with water for injection and passed through a filter. If necessary, in order to increase or decrease the concentration of active substances, the pharmaceutical composition may be lyophilized. 7 020558. If necessary, reduce the concentration of the Me1-C1i-H | 5-RNe-Progo-C1u-Progo peptide. preparation of 2-ethyl-6-methyl-3-hydroxypyridine succinate and minerals, for example, 10 liters of water were added to the resulting solution twice. The solution was mixed with water in a reactor with a stirrer with a volume of more than 22 l. Thus, all the compositions indicated in the table were obtained. 1-24.

Example 3

Tests for general toxicity were carried out by intraperitoneal administration to rats of pharmaceutical formulations based on the Me1-O1i-H18-Rie-Rgo-O1u-Rgo peptide, the preparation of 2-ethyl-6-methyl-3-hydroxypyridine succinate and mineral substances.

For studies of the concentration of components in solutions selected, mg / l:

LO ₅₀ is up to 1000 mg / kg when administered intraperitoneally.

With intramuscular administration, L0 ₅₀ is up to 3000 mg / kg, which allows the claimed compounds to be classified as non-toxic substances.

Example 4

The antioxidant activity of pharmaceutical compositions based on the Me1-O1i-H18-Rie-Rgo01u-Rto peptide, the preparation of 2-ethyl-6-methyl-3-hydroxypyridine succinate, mineral substances and ¹³ C isotopes was compared with the antioxidant activity of the drug mexidol chemiluminescent method [7 ].

In the pharmaceutical formulations, the content of the Me1-O1i-H18-Rie-Rgo-O1u-Rgo peptide is 0.5 mg / L, the content of the 2-ethyl-6-methyl-3-hydroxypyridine succinate preparation is 50,000 mg / L. The preparation Mexidol contained the peptide Me1-O1i-H18-Rie-Pro-O1u-Pro - 50,000 g / l. The serial numbers of the pharmaceutical formulations 4956 (see table. 7).

The effect of Mexidol was also compared with pharmaceutical compositions based on the Me1-O1i-H18-Pbe-Rgo-O1u-Rgo peptide, the preparation of 2-ethyl-6-methyl-3-hydroxypyridine succinate, mineral substances and with a carbon content of ¹³ C equal to 0.5 and 75% of all carbon in the pharmaceutical composition (see tables. 8 and 9).

The results of the comparison of pharmaceutical formulations with Mexidol are given in table. 25.

According to antioxidant activity (AOA), pharmaceutical formulations based on the peptide Me1-O1i-H18-Pbie-Prgo-O1u-Rgo, the preparation of 2-ethyl-6-methyl-3-hydroxypyridine succinate and mineral

- 8,020,558 substances generally exceeded Mexidol by up to 24%.

It was also found that, according to their antioxidant activity, pharmaceutical compositions based on the Me1-O1i-H18-Pbe-Pro-O1u-Progo peptide, the preparation of 2-ethyl-6-methyl-3-hydroxypyridine succinate, mineral substances and with a carbon isotope content of ¹³ C to 75% of the total carbon in the pharmaceutical composition was generally superior to mexidol by up to 29%.

Pharmaceutical formulations with serial numbers 49, 57 and 65 did not exceed Mexidol.

Pharmaceutical formulations with serial numbers 55 and 56 for AOA practically did not exceed pharmaceutical composition No. 54.

Pharmaceutical formulations No. 63 and 64 for AOA did not exceed pharmaceutical composition No. 62.

Pharmaceutical formulations No. 71 and 72 in terms of AOA did not exceed pharmaceutical composition No. 70. In formulations No. 71 and 72, a slight decrease in AOA was observed.

Therefore, the pharmaceutical compositions No. 55 and 56, 63 and 64, 71 and 72 to use as an antioxidant agent is not economically feasible (costly). In addition, for AOA, compositions No. 56, 64, and 72 were somewhat inferior to Mexidol. AOA of pharmaceutical formulations No. 169-192 was also investigated.

It was found that in terms of antioxidant activity, these pharmaceutical formulations generally exceeded Mexidol by up to 5%.

Studies on the antioxidant activity of pharmaceutical formulations were also carried out according to the method [8]. The results are similar to the above.

Example 5

The antihypoxic and neurometabolic activity of pharmaceutical compositions based on the Me1-O1i-H18-Rie-Rgo-O1u-Rgo peptide, the preparation of 2-ethyl-6-methyl-3-hydroxypyridine succinate, mineral substances and containing ¹³ C carbon isotopes was compared with the activity of the drug mexidol .

Comparisons were made on white non-linear mice (males) weighing 25-27 g for acute hypoxia [9,

10].

Acute hypoxia (normobaric hypoxic hypoxia) was modeled by placing mice in a 250 cm ³ heat chamber.

In the experiments, the lifespan of animals was recorded after the cessation of air access to the heat chamber. Animals were placed in a heat chamber individually.

Mexidol was administered once intraperitoneally 30, 60 and 90 minutes before placing the mice in the heat chamber and stopping air from entering the heat chamber.

The time from the moment of drug administration to the placement of mice in a heat chamber and cessation of air access in the tables is indicated by Tv in minutes.

Each of the pharmaceutical compositions based on the peptide Me1-O1i-H18-Pb-Prgo-O1u-Prgo, the preparation of 2-ethyl-6-methyl-3-hydroxypyridine succinates and minerals was administered once intraperitoneally also 30, 60 and 90 minutes before room mice into the heat chamber and stopping air from entering the heat chamber.

After placing mice in a heat chamber, as oxygen was consumed, its concentration in the air and in the body of mice decreased, and the amount of carbon dioxide increased. As a result, animals developed acute hypoxic hypoxia. Life expectancy (until breathing stopped) was recorded using a stopwatch, and the effectiveness of the tested drugs was judged by its increase.

Comparison results of the antihypoxic and neurometabolic activity of pharmaceutical formulations based on the Me1-O1i-H18-Rie-Rgo-O1u-Rgo peptide, the preparation of 2-ethyl-6-methyl-3-hydroxypyridine succinate, mineral substances and ¹³ C carbon isotopes containing the antihypoxic activity of the drug mexidol are given in table. 26-29.

On the model of acute normobaric hypoxic hypoxia (in a heat chamber) it was found that most pharmaceutical formulations based on the peptide Me1-O1i-H18-Pbie-Prgo-O1u-Rgo, the preparation of 2-ethyl-6-methyl-3-hydroxypyridine succinate and mineral substances increased the life expectancy of mice by up to 16% compared with mexidol.

An increase in the speed of the onset of the therapeutic effect was established while maintaining the duration of action without increasing the concentration of the pharmaceutical agent. This is clearly seen in the table. 29. The claimed drugs increase the onset of the therapeutic effect, which brings together the values of life expectancy at Tv = 30 min and Tv = 60 and 90 min.

An increase in the therapeutic effect was achieved without increasing the concentration and quantity of the Me1-O1i-H18-Pbe-Prgo-O1y-Prgo peptide and the preparation of 2-ethyl-6-methyl-3-hydroxypyridine succinate.

Comparisons were also made on the following models: acute hypobaric hypoxia in an exhaust pressure chamber with imitation of raising animals at a speed of 50 m / s to a height of 11000 m; acute hemic hypoxia and acute histotoxic hypoxia.

The results of these comparisons are similar to those obtained in the acute normobaric hypoxic hypoxia model.

In addition, studies were conducted to increase the concentration of the peptide Me1-O1i-H18-Rye-Progo-O1u-Pro to a value of 30 mg / l and the preparation 2-ethyl-6-methyl-3-hydroxypyridine succ-9 020558 cinnate to a value of 300 g / l An increase in the effectiveness of action was observed compared with the best pharmaceutical compositions mentioned above based on the peptide Me! -O1i-Ht8-Pbe-Prgo-O1y-Prgo and the preparation 2-ethyl-6-methyl-3-hydroxypyridine succinate. However, the increase in efficiency did not exceed 3-5%. An increase in the concentration of the Me! -O1i-H18-Rye-Pro-O1u-Pro peptide of more than 30 mg / L, in particular up to 100 mg / L, did not lead to an increase in efficiency compared to the best pharmaceutical formulations.

Also, the effectiveness of Mexidol was compared with the effectiveness of the pharmaceutical compositions No. 1-48. It was found that compounds No. 1-24 exceeded the effect of Mexidol by about 3%. Compositions 25-48 in their effect exceed the effect of Mexidol by no more than 5%.

Example 6

The neuroprotective effect of pharmaceutical formulations based on the Me! -O1i-H18-Rye-Rgo-O1u-Rgo peptide, the preparation of 2-ethyl-6-methyl-3-hydroxypyridine succinate, mineral substances and ¹³ C carbon isotopes was compared with the neuroprotective effect of the drug mexidol .

When comparing the content of the drug 2-ethyl-6-methyl-3-hydroxypyridine succinate - 10 g / l, the peptide Me! -O1c-H18-Rie-Pro-O1u-Pro - 0.1 mg / l, Mexidol - 10 g / l ( diluted with water 1: 5).

Comparative studies were performed on white non-linear male rats weighing 250-270 g, in which ischemic stroke and hemorrhagic stroke were simulated.

Ischemic stroke in rats was reproduced by bilateral ligation of the common carotid arteries. The experimental animals were injected intraperitoneally with Mexidol and the claimed pharmaceutical compositions with serial numbers from 25 to 48. The characteristics of these pharmaceutical compositions are given in table. 4-6.

Animals after surgery were observed for 2 weeks, taking into account the survival of rats. Neurological deficit in animals was determined every hour during the first 24 hours, and then 1 time per day. The severity of the condition was determined by the sum of the corresponding points.

The results of the study of the neuroprotective effects of drugs are presented in table. 30. An analysis of the results shown in the table showed that in rats who received intraperitoneal injection of mexidol, the neurological deficit was most pronounced (5.3 ± 0.1 points) 3, 4, and 5 days after bilateral ligation of the common carotid arteries. The number of rats in the experiment is 12. Of these, 2 animals died (16.67%).

In experiments, it was found that the compositions based on the preparation of 2-ethyl-6-methyl-3-hydroxypyridine succinate, the peptide Me! -O1i-H18-Rie-Pro-O1u-Pro, mineral substances and carbon isotopes ¹³ C in doses of 20 mg per day, the rat has a pronounced neuroprotective effect, generally superior in severity to the neurological deficit of mexidol.

Twenty four experiments were performed with rats that received an intraperitoneal pharmaceutical composition based on the preparation of 2-ethyl-6-methyl-3-hydroxypyridine succinate, the peptide Me1-C1i-H | 5-RNe-Rgo-C1u-Rgo. mineral substances and carbon isotopes ¹³ C. The number of rats in each experiment is 12. In the experiments 10-15% of animals died.

Pharmaceutical formulations No. 25, 33 and 41, as well as 31, 32, 39, 40, 47, 48, do not surpass Mexidol in neuroprotective effect (see Table 30). The neuroprotective effects of the remaining compounds are superior to the neuroprotective effect of Mexidol.

The most pronounced neuroprotective effect in pharmaceutical formulations No. 29, 30, 37, 38, 45, 46. However, the following should be considered.

Pharmaceutical composition No. 30 in its neuroprotective effect does not exceed composition No. 29. Therefore, composition No. 30 is inappropriate to use.

Pharmaceutical composition No. 38 in its neuroprotective effect does not exceed composition No. 39. Therefore, composition No. 38 is not practical to use.

Pharmaceutical composition No. 46 in its neuroprotective effect does not exceed composition No. 45. Therefore, composition No. 46 is inappropriate to use.

Hemorrhagic stroke (GI) in rats was reproduced by modeling local hemorrhage in the brain (creating GI with cerebral ischemia) according to the method [11]. In accordance with the technique, rat skull trepanation and brain tissue destruction were performed in the area of the internal capsule with the subsequent injection of the same rat into the site of blood damage (0.03 ml of blood). Thus, a stroke was achieved in the area of the internal capsule with virtually no damage to neighboring brain tissues.

The pharmaceutical composition based on the preparation of 2-ethyl-6-methyl-3-hydroxypyridine succinate, the Me! -O1i-H18-Rye-Rgo-O1u-Rgo peptide, mineral substances and ¹³ C carbon isotopes was administered intraperitoneally to animals at a dose of 20 mg per day to the rat. Mexidol was also administered intraperitoneally to animals at a dose of 20 mg per day in rats. The administration schedule was as follows: the first injection was carried out 2 hours after the operation, then 3 injections after 4 hours. Then the pharmaceutical composition based on the preparation of 2-ethyl-6-methyl-3-hydroxypyridine succinate, Me! -O1i-H18-Rye peptide Рgo-О1у-Рго and minerals, as well as mexidol was administered daily once a day for 14 days.

- 10,020,558

Within 14 days after the operation, coordination of movements on a rotating rod for 2 min and the ability of the drugs to increase the survival of animals were evaluated (see table. 31).

It was established that pharmaceutical compositions No. 25, 33 and 41, 31, 32, 39, 40, 47, 48 in coordination of movement on a rotating rod practically do not exceed Mexidol. The neuroprotective effects of the remaining compounds are superior to the neuroprotective effect of the drug mexidol.

The coordination of rat movement increases markedly with the use of compounds No. 28-30 (see the characteristics of the compositions in table. 4), 36-48 (see the characteristics of the compositions in table 5), 44-46 (see the characteristics of the compositions in table 6) . However, the following should be considered.

Pharmaceutical composition No. 30 in its neuroprotective effect does not exceed composition No. 29. Therefore, composition No. 30 is not practical to use in practice.

Pharmaceutical composition No. 38 in its neuroprotective effect does not exceed composition No. 37. Therefore, composition No. 38 is not practical to use in practice.

Pharmaceutical composition No. 46 in its neuroprotective effect does not exceed composition No. 45. Therefore, composition No. 46 is not practical to use in practice.

Pharmaceutical formulations based on the preparation of 2-ethyl-6-methyl-3-hydroxypyridine succinate, the peptide Me1-O1i-H18-Rie-Rgo-O1u-Rgo, mineral substances and ¹³ C carbon isotopes increase (compared with mexidol) rat survival after operations.

In addition, studies have been conducted to increase the concentration of the preparation of 2-ethyl-6-methyl3-hydroxypyridine succinate to 300 g / l and above, the Me1-O1c-H18-Rie-Rgo-O1u-Rgo peptide to 30 mg / l and above. There was an increase in the effectiveness of the compositions with increased concentrations compared to the best pharmaceutical compositions mentioned above based on the preparation of 2-ethyl-6-methyl-3-hydroxypyridine succinate, the peptide Me1-O1c-H18-Rie-Rgo-O1u-Rgo (see table. thirty). Effectiveness increased by 3-5%. A further increase in the concentration of the preparation of 2-ethyl-6-methyl-3-hydroxypyridine succinate and the peptide Me1-O1i-H18-Rye-Progo-O1u-Pro led to a decrease in efficiency compared to the best pharmaceutical compositions mentioned above.

Also, the effectiveness of Mexidol was compared with the effectiveness of the pharmaceutical compositions No. 1-48, 169-192. It was found that compounds No. 1-24, 169-192 exceeded the effect of Mexidol by about 3%. Compounds No. 25-48 in their action surpass the action of Mexidol by no more than 5%.

Example 7

The anti-amnestic effect of pharmaceutical formulations based on the preparation of 2-ethyl-6-methyl-3-hydroxypyridine succinate, the Me1-O1c-H18-Rye-Progo-O1u-Progo peptide, mineral substances and ¹³ C carbon isotopes was compared with the antiamnistic effect of the drug mexidol.

Comparisons were made on white non-linear mice (males) weighing 25-27 g.

The effect of pharmaceutical formulations based on the preparation of 2-ethyl-6-methyl-3-hydroxypyridine succinate, the peptide Me1-O1c-H18-Rie-Pro-O1u-Pro, mineral substances and carbon isotopes ¹³ C and the drug mexidol on amnesia (learning processes and memory) in mice was investigated using a conditioned reaction of passive avoidance of electrodermal irritation. The mice were exposed to electroconvulsive shock (current 30 mA for 0.3-0.5 s to the auricles) immediately after learning the conditioned passive avoidance reaction (model of amnesia caused by electroconvulsive shock) [10, 12].

The effect of pharmaceutical formulations based on the preparation of 2-ethyl-6-methyl-3-hydroxypyridine succinate, the peptide Me1-O1c-H18-Rie-Pro-O1u-Pro, mineral substances and carbon isotopes ¹³ C and the preparation Mexidol for amnesia was also evaluated on the model scopolamine amnesia after learning a conditioned reaction of passive avoidance [10].

The drugs were administered once intraperitoneally 30, 60 and 90 minutes before the training of mice. The safety of the conditioned reaction of passive avoidance was checked 24 hours after the amnesiac effect.

On the model of amnesia caused by electroconvulsive shock, it was found that in mice pharmaceutical formulations based on the preparation of 2-ethyl-6-methyl-3-hydroxypyridine succinate, the peptide Me1-O1c-H18-Rie-Rgo-O1u-Rgo, mineral substances and carbon isotopes ¹³ C, as well as the drug Mexidol actively prevent the development of amnesia of the conditioned reaction of passive avoidance (see table. 32).

Table analysis 32 shows that pharmaceutical formulations based on the preparation of 2-ethyl-6-methyl-3-hydroxypyridine succinate, the Me1-O1c-H18-Rie-Pro-O1u-Progo peptide, mineral substances and ¹³ C carbon isotopes increase the onset of the therapeutic effect while maintaining the duration actions without increasing the concentration of active substances in a pharmaceutical agent.

The above effects can be achieved through the use of Mexidol by increasing the dose of Mexidol or its concentration in the dose. In the experiments (see table. 32), the amount of Mexidol was increased from 20 to 40 mg per mouse.

On the model of scopolamine amnesia, it was found that in mice pharmaceutical formulations based on the preparation of 2-ethyl-6-methyl-3-hydroxypyridine succinate, the Me1-O1c-H18-Rie-Rgo-O1u-Rgo peptide, mineral substances and ¹³ C carbon isotopes , as well as the drug Mexidol also prevent the development of amnesia of the conditioned reaction of passive avoidance (see table. 33).

Pharmaceutical formulations based on the peptide of the preparation of 2-ethyl-6-methyl-3-hydroxypyridine succinate, Me! -C1i-H18-Pbe-Prgo-C1u-Prgo, mineral substances and ¹³ C carbon isotopes increase the rate of onset of the therapeutic effect while maintaining the duration of action without increasing the concentration of the pharmaceutical.

An increase in the speed of the onset of the therapeutic effect and an increase in the therapeutic effect due to the use of Mexidol can be achieved by increasing its amount in the injection.

Example 8

The anti-ischemic effect of pharmaceutical compositions based on the Me! -C1i-H18-Pb-Pe-Pro-C1u-Pro peptide, minerals and carbon ¹³ C isotopes was compared with the anti-ischemic effect of the drug mexidol. The comparison results are presented in table. 34 and 35.

Studies were conducted on white non-linear mice (males) weighing 35-37 g.

Brain ischemia was reproduced by ligation of both common carotid arteries. Animals after surgery were observed for 7 days. Pharmaceutical formulations based on the preparation of 2-ethyl-6-methyl-3-hydroxypyridine succinate, the Me1-C1i-H18-Pbe-Prgo-C1u-Prgo peptide and minerals, and the preparation Mexidol were administered intraperitoneally for 7 days. On the first day, drugs were administered twice: immediately after surgery and 3 hours after surgery. In the second, third, etc. until the seventh day, the drugs were administered once a day.

After bilateral ligation of the common carotid arteries (and not using the above drugs), more than 90% of the mice died during the observed days.

Pharmaceutical formulations based on the preparation of 2-ethyl-6-methyl-3-hydroxypyridine succinate, the peptide Me! -C1i-H18-Pbe-Pro-C1u-Pro, mineral substances and carbon isotopes ¹³ C, as well as the drug mexidol significantly increased the survival of mice during the observation period. In this case, the concentration of the peptide Me1-C1i-H18-Pbe-Prgo-C1u-Prgo ranged from 0.1 to 30 mg / L. The concentration of the drug 2-ethyl-6-methyl-3-hydroxypyridine succinate was 1 and 300 g / L. From the table. 34 and 35, it can be seen that the survival of mice using the majority of pharmaceutical formulations based on the preparation of 2-ethyl-6-methyl-3-hydroxypyridine succinate, the peptide Me1-C1i-H18-Pbie-Prgo-C1u-Prgo, minerals and carbon isotopes ¹³ C is higher than the survival rate of mice when using Mexidol.

At present, ¹³ C carbon isotopes in the world are widely used in biochemistry and medicine for diagnostics. The description presents the results of our own studies on the effect of ¹³ C carbon isotopes on the stability and effectiveness of the action of medicinal formulations based on the Me1C1i-H18-Pb-Pe-Cl-C1u-Prgo peptide and the preparation of 2-ethyl-6-methyl-3-hydroxypyridine succinate.

It was found that increasing the stability of the claimed pharmaceutical composition over the expiration date can be achieved by replacing (from 0.5 to 75%) ¹² C carbon isotopes with ¹³ C carbon isotopes. It was found that ¹³ C carbon isotopes in the molecules of the Me1-C1i-H18 peptide -Pe-Pro-Cl-Cl-Pro and 2-ethyl-6-methyl-3-hydroxypyridine succinate molecules slow down the chemical reactions occurring in the molecules, form stronger covalent bonds than carbon isotopes ¹² C.

Carbon isotopes ¹³ C increase the resistance of molecules to the oxidative effects of radicals.

Carbon isotopes ¹³ C are non-toxic. The experiments show that feeding mice and rats with foods enriched with 75% ¹³ C carbon does not lead to side effects and poor health.

In the process of experimental verification of the claimed pharmaceutical compositions enriched in carbon ¹³ C isotopes, it was found that these compositions have increased stability, they are non-toxic and, in addition, have increased neuroprotective, antiamnestic, antioxidant, antihypoxic, anti-ischemic activity compared to a pharmaceutical composition in which no carbon isotopes ¹³ C.

Methods for the production of stable highly enriched non-radioactive carbon isotope ¹³ C are widely used in Russian and world industry. Well developed methods for producing carbon isotope ¹³ C by gas diffusion through the porous walls, the diffusion in a vapor stream, thermal and distillation method, an isotope exchange, centrifugation, electrolysis, genetic engineering and others. Brief description of these methods is given in reference [13].

At the Moscow State Academy of Fine Chemical Technology. M.V. Lomonosov practiced modern nanotechnology for the production and incorporation of atoms of stable carbon isotopes ¹³ C into molecules of various structures. At the academy, molecules of isotopically labeled compounds with various levels of isotope enrichment are obtained - from fractions of a percent to 100% of isotopes in a substance. The work is in the interests of medical diagnosis. The source [14] contains 165 references to foreign sources of information on the isotopic enrichment of various substances.

In turn, the authors actively participated in the work on the isotopic enrichment of hydrocarbons, as well as reagents for the production of various drugs. The reagents were enriched with ¹³ C carbon isotopes (replacing ¹² C carbon isotopes with ¹³ C carbon isotopes) in a cavitation reactor designed by Professor V. I. Kormilitsyn. (Moscow Energy Institute Technical University).

- 12,020,558

The reactor was manufactured according to the procedure given in the source [15]. The flow velocity in the reactor, along the length of the channel, varied from 10 to 50 m / s.

In FIG. 36 is a diagram of a cavitation reactor for isotope enrichment of various mixtures, in particular hydrocarbon reagents, for the preparation of the peptide Me1-C1i-H18-Rie-Rgo-C1u-Rgo and 2-ethyl-6-methyl-3-hydroxypyridine succinate enriched in carbon isotopes ¹³ C. The reactor is located in the installation, which contains the pump 6NK-6x1, providing a maximum flow rate of 90 m ³ / h, a pressure of 125 m with an electric motor power of 75 kW, a rotational speed of the electric motor rotor and pump wheels of 2950 rpm. Additionally, the installation contains tanks for reagents and measuring instruments.

The enrichment of 2-ethyl-6-methyl-3-hydroxypyridine succinate with ¹³ C isotopes of carbon is carried out similarly.

The installation diagram is shown in FIG. 38.

The cavitation reactor 1 (see Fig. 36) is made in the form of a flat Laval nozzle with cavitation bodies 2-9 in the channel 10.

In FIG. 37 is a cross-sectional view of a cavitation reactor. The reactor channel in the area of cavitation bodies is divided into several channels. For example, cavitation bodies 5 and 6 divide the channel into smaller channels 13, 14 and 15. Outside, the channel is limited by walls 16 and 17, as well as two covers 11 and 12.

In FIG. 16, arrows 18 show the direction of movement of the reagent at the inlet to the reactor, arrow 19 shows the direction of movement of the reagent at the outlet of the reactor.

In the wall 16, channels 24 and 25 are made for supplying carbon dioxide and nitrogen to the cavitation zones.

Installation works as follows. The hydrocarbon reagent from the tank 28 is pumped through the reactor 27 through the pump 27 and enters the tank 28. The pressure drop in the reactor is controlled by pressure gauges 29 and 30. The temperature of the reactant is monitored by thermometer 31. The reagent is heated in the tank by a heater 32.

When the reactor is operating, the hydrocarbon reagent moves along the cavitator channel in direction 18. When flowing around cavitation bodies, the stream is divided into several streams. Beyond the cavitation bodies, cavitation areas arise. In particular, behind the bodies (if you look in the direction of movement of the reagent) cavitation 2, 3, and 4 are cavitation zones 20, 21, 22, and 23. Upon entering the cavitation region, the reagent boils cavitation bubbles; when leaving the cavitation region, cavitation bubbles collapse. Moreover, in the area (in the place) of the collapse of the cavitation bubble, an increase in pressure is observed to several thousand atmospheres and an increase in temperature to 1000 ° C or more. Through channels 24 and 25, carbon dioxide is supplied to the stream so that the gas enters the cavitation zone.

The gas-vapor mixture obtained in the reactor together with the liquid reagent enters the tank 28. Next, the gas-vapor mixture is fed through a pipe 33 to a separator with a porous partition, where the gas-vapor mixtures with ¹³ C and ¹² C are separated.

In the experiments, the reactor worked from several hours to several days. A direct dependence of the degree of enrichment of the vapor-gas mixture and the reagent with the ¹³ C isotope ^{on the} operating time of the cavitation reactor is established.

The amount of ¹³ C carbon isotopes was controlled by high resolution mass spectroscopy.

As a result of the experiments, the reagent was enriched with the ¹³ C carbon isotope to 75%.

Thus, pharmaceutical compositions were obtained containing the Me1-C1i-H18-Rie-Pro-C1-Pe-Pro peptide with a carbon content of ¹³ C from 0.5 to 75% of the total carbon in the pharmaceutical composition.

The enrichment of 2-ethyl-6-methyl-3-hydroxypyridine succinate with ¹³ C isotopes of carbon is carried out similarly.

Thus, the implementation of the claimed pharmaceutical compositions provides: an increase in the speed of the onset of the therapeutic effect (decrease in the time of the onset of the therapeutic effect) while maintaining the duration of action without increasing the concentration of the methionine-glutamine-histidine-phenylalanine-prolyl-glycine-proline (Me1-C1i-H18- Rye-Rgo-C1u-Rgo) and the preparation of 2-ethyl-6-methyl-3-hydroxypyridine succinate in the treatment of disorders of the nervous system, ischemia and hypoxia of the central nervous system and myocardium, amnesia, as well as with an increase activity of the endogenous system and a decrease in the intensity of free radical processes;

an increase in the therapeutic effect without increasing the concentration of the methionine-gluthingistidine-phenylalanine-prolyl-glycine-proline polypeptide (Me1-C1i-H18-Rye-Rgo-C1u-Rgo) and the 2-ethyl-6methyl-3-hydroxypyridine succinate preparation in the treatment of nervous system disorder , ischemia and hypoxia of the central nervous system and myocardium, amnesia, as well as with an increase in the activity of the endogenous system and a decrease in the intensity of free radical processes;

increasing the stability of the pharmaceutical composition with the methionine-glutamististidine-phenylalanine-prolyl-glycine-proline polypeptide (Me1-C1i-H18-Rie-Rgo-C1u-Rgo) and the preparation of 2-ethyl-6methyl-3-hydroxypyridine succinate over the shelf life.
