SODIUM SALT OF IPOLY-(2,5-DIHYDROXyPHENYLENE)I-4-THIOSU ACID OF LINEAR STRUCTURE AS REGULATOR OF CELL METABOLISM AND PRODUCTION METHOD THEREOF Technical Field This invention relates to the field of a medicine and biology and concerns to preparations, regulating metabolism of a cell, which can be used for preventive maintenance and treatment of various diseases, as well as in the research purposes.

Background Art The majority of medicinal preparations, which are used now, are specific in the sense that their action is directed on elimination of the particular specific reasons and/or consequences of some pathological conditions.

However, there is a group of medicinal preparations of more general action, which biological activity is displayed in normalization of correct functioning of a live cell, breaking as a result of effect of adverse factors.

Among medicinal preparations permitted to medical application there is, for example, the group of therapeutic means, which render favorable influence on metabolic processes in a cell and display as a result the desired multifactor physiological effect (see, for example, M.D.Mashkovsky, "Medicinal Means" 11th ed., Moscow, "Medicine", 1988].

For example, cytochrome C accelerates a course of oxidizing processes; it is applied to improve of the tissue breath.

Adenosyne threephosphate influences actively general metabolism processes and consequently is widely applied to improve brain and coronary blood circulation.

Retabolyle and other anabolic steroids render positive influence on nitride exchange and moreover promote calcium ration in bones.

Cerebrolysine, which represents a hydrolyzate of a brain substance, normalizes metabolism processes in the brain tissue; it is applied at breaks of central nervous system functions.

Ubiquinone normalizes the physiological condition of a cell in the state of hypoxya [see G.I.Andreeva "Influence of Ubiquinones and Their Analogues on Breath Circuit Ferments Activity", Microbiology, 1979, v.48, No.6, pp. 969-974].

The stacking-spiralized ortho-oligomer, containing hexa-cyclolinear nucleus, which quantity on a helix turn of a secondary structure of the oligomer is from 2.6 to 3, and having in the helix of the oligomer secondary structure more than 1, but less than 10 turns, is one of the most effective known preparations, capable to influence positively on a physiological condition of a cell.

An example of such stacking-spiralized ortho-oligomer, is the oligo-1,6-(2,5-dioxyphenilene)-thiosulfate of sodium.

Oligomers described above are the family of individual monomers, having benzol nucleuses in the structure in amount from 3 to 30.

The methods of separation of individual monomers and condition of a production of some or other monomers of a determined length and conventional purity are not described.

Standardization of the ready medicinal preparations is difficult in some extent under these circumstances.

Known substances dissolvable in water, spirit, acetone, but not dissolvable in the dimethyl ether.

Oligomrs of the similar structure have an ability to render regulating effect on functioning of bioenergetic systems of eukaryot and procaryot cells. See international application WO 96/08527 published on 21 March 1996 (21.03.96), IPC C08G61/10, which is considered by the applicant as the nearest to his invention. A helix structure of the compound disclosed in that application and a stacking between turns of the helix were considered as characteristics which determine a biological activity of the compound.

A method of production of afore mentioned compound consists in that interaction is provided of para-benzoquinone and sodium thiosulfate in water-acetone medium at temperature not higher than 37 degrees, separation of the final product precipitation and deletion of impurities by divetyl ether extraction.

All afore mentioned preparations have a spectrum of properties inherent to each of them, which determine a character of their practical application.

It is obvious from the state of the art that increase of means influencing on such fundamental properties of cells, as its metabolism is the actual target in the medicine and biology.

There are no routine ways for a search of substances with desired properties: finding of such substances relates to the inventive activity.

Disclosure of Invention The objective of this invention is to broaden of a range of means, influencing on cells metabolism.

There was unexpectedly established as a result of research efforts by the applicant that the linear analogues of the known stacking-spiralized ortho-oligomers have the same biological activity as it was described previously for the spiral structure oligomers.

By other words, the linear oligomers of a similar chemical nature, but having no spiral configuration, appear capable to render regulating influence on cells metabolism.

In particular, the linear oligomer which have such ability is the oligo-1,6-(2,5-dioxy-phenilene)-thiosulfate of sodium, which applicant considers more correct to name hereinafter as the sodium salt of [poly-(2,5-dihydroxy-phenilene)3-4-thiosulfonic acid.

This linear polymer is a mixture of monomers, including compounds having from 2 to 6 benzol nucleuses.

There was no possibility to produce individual monomers - components of the polymer mixture of a satisfactory purity, but it is possible to produce the polymer mixture comprising preferably monomers of the required length by varying conditions of chemical synthesis of these compounds.

The molecular mass of the polymer compound can be in the limits from 352 to 784.

The compound is a powder of black colour with no smell, a little salted by taste.

It is easily dissolvable in water and practically not dissolvable in 95% of ethanol, aceton or diethyl ether.

It has no precise melting point temperature.

Extinction of 0.0032 solution in water at the wavelength of 305 nm is 18.9 l/g*cm.

The ultraviolet spectrum shows brightly expressed maximum at the wavelength of 305 T 1 nm.

The place of the maximum does not change at change of the pH value in the range from 5.0 to 9.0, i.e. the hypso- and bathocromic effects are absent, that testifies for certain that the polymer does not contain spiral structures.

Absorption bands in infrared spectrum are in areas of 610-630 cm-1 , 790-810 cm-l, 1195-1215 cm-t, 1440-1460 cm-1 The polymer product shows expressed biological activity, displayed in respect of microorganisms, desegregated cells of a living tissue, animals and humans.

Its main direction of biological action is the normalization and optimization of living cells metabolism, especially in hypoxya conditions.

Other important feature of the proposed polymer is its property to increase the working ability of an organism.

A method of production of the sodium salt of [poly-(2,5-dihydroxy-phenilene)]-4-thiosulfonic acid consists in that interaction is provided of para-benzoquinone and sodium thiosulfate in organic solvent medium at temperature of 40 te 70 °O, separation of the final product precipitation and purification by ethyl alcohol.

Interaction is preferably provided in water-aceton medium.

Thus, the claimed compound differs from the nearest known structural and functional analogue with similar biological activity by following features: - it has a linear and not a spiral configuration; - it is a mixture of monomers and not a separate individual monomer; - it is not dissolvable in spirits and acetone, in difference from the analogue; - it is produced by a method which parameters differ from the method of production of the analogue.

The method of production of the claimed compound has a distinction consisting in that the polymer synthesis is carried out at higher temperature, namely at the temperature of 40 to 70 °C.

Brief Description of Drawings Fig.1 represent a dependency of the produced polymeric product molecule mass on the initial products ratio.

Fig.2 shows the ultraviolet spectrum of the produced polymeric product.

Fig.3 shows the infrared spectrum of the produced polymeric product.

Detailed description of the invention The applicant has proven, by an experimentation, that the stacking-spiralized configuration of oligomers belonging to the row of oligo-1,6-(2,5-dioxyphenilen)-thiosulfate of sodium is not the necessary condition for biological activity, directed on normalization and optimization of live cell functions.

It was discovered, in particular, that the sodium salt of [poly-(2,5-dihydroxy-phenilene)-4-tiosulfonic acid, which is

the linear polymer, has the ability of positive influence on metabolism processes in a cell.

This result is not obvious, because it is known, that the molecule properties are defined by its space orientation and, in particular, the unique properties of nucleic acids are connected just with its particular three-dimentional space position.

It is quite correct, in this connection, to consider chemical compounds, characterized by its space structures, as separate individual substances.

The claimed polymer compound has the following structural formula: where n = 0 ; 4.

The polymer compound has the molecular mass in limits from 352 to 784. The molecular formula of the compound is NaS2Cl2+6nO7+2nHt0+6n .

The polymer is a mixture of separate monomers, it contains monomers with structure having from 2 to 6 benzol nucleuses.

The ratio of monomers in the polymeric product can differ, but, as it was shown in experiments, this ratio does not render decisive influence to a degree of biological activity of such preparation.

Nevertheless, it is possible to produce the polymeric product with the standard composition of monomers, if observing identical conditions.

Moreover, it is possible to synthesize the product with a different ratio of monomers by selection of the synthesis appropriate conditions.

Fig.1 shows the general tendency of changes of produced polymeric product molecule mass versus the initial products ratio, which describes indirectly the monomer composition in the final mixture.

The compound is a powder of black colour with no smell, a little salted by taste.

It is easily dissolvable in water and practically not dissolvable in 958 of ethanol, aceton or diethyl ether.

It has no precise melting point temperature.

Extinction of 0.003% solution in water at the wavelength of 305 nm is 18.9 l/g*cm.

The ultraviolet spectrum shows brightly expressed maximum at the wavelength of 305+1 nm (see Fig.2).

The place of the maximum does not change at change of the pH value in the range from 5.0 to 9.0, i.e. the hypso- and bathochromic effects are absent, that testifies for certain that polymer does not contain spiral structures.

It is characterized by absorption bands in the infrared spectrum area of 610-630 cm-t, caused by groups C-S and S-O valency oscillations; in the area of 790-810 cm-1, caused by non-planar deformation oscillations of non-substituted hydrogen atoms in the benzol ring; in the area of 1195-1215 cm-1, caused by deformation oscillations of C-OH in the aromatic ring; in the area of 1440-1460 cm-l, caused by group C-S valency oscillations (See Fig.3). The other bands of absorption, which appear in the spectrum, are not characteristic, they are overlapped by spectra of initial reaction products and were not identified.

The main basic difference of patented compound from its nearest analogue consists in that the known compound has a spiral structure, whereas the proposed compound has no spiral structure, it is the linear polymer.

The claimed compound is a mixture of monomers and the monomers in the mixture contains in its structure from 2 to 6 benzene nucleuses, whereas the known compound is a family of individual monomers containing from 3 to 30 benzol nucleuses.

Besides, the known and proposed compounds characterized by different solubility: in distinction of the known compound, the proposed one is not dissolvable in the spirits and aceton.

A biological activity of the proposed sodium salt of tpoly-(2,5-dihydroxy-phenilene)]-4-tiosulfonic acid was studied on cells cultures, microorganisms, animals and human beings; some results are indicated below.

The whole complex of the applicant's experimentation results gives the basis for a conclusion that the claimed compound normalizes and optimizes the live cell metabolism for any tested organisms representing the various stages of evolution.

A visible side of favorable effect of the claimed compound on metabolism consists, in particular, in more active growth of desegregated cells of a live tissue, in greater microorganisms production activity, in increase of serviceability of the experimental animals, and in antihypoxya effect for the human beings.

This parameter is especially important, as far as just the isolated cells of living tissue are the most sensitive toxicity revealing test-system of all ones used for this purpose.

Revealing of stimulating action of the claimed compound at the microorganism level was made, in particular, by treatment of the commercial Aspergillus niger strain which is the producer of the citric acid.

The preparation has no cancerogenous or mutagenous properties. Toxicity of the preparation is low. It makes more

than 1500 mg/kg of weight at intravenous injection to white mice, while an average effective therapeutic dosage makes about 30 mg/kg of weight.

It can be prepared in such conventional medicinal forms, as a solution, powders, tablet, ointments.

A method of production of the sodium salt of [poly-(2,5-dihydroxy-phenilene)]-4-thiosulfonic acid consists in that interaction is provided of para-benzoquinone and sodium thiosulfate in organic solvent medium at the temperature of 40 to 70 00, separation of the final product precipitation and purification by ethyl alcohol.

In the preferable mode of realization of the claimed method interaction is provided of the para-benzoquinone solution in acetone and sodium thiosulfate water solution at the temperature of 40 to 70 00, separation of the final product precipitation and purification by boiling ethyl alcohol.

The molar ratio of para-benzoquinone and sodium thiosulfate should be maintained in limits 10:1 to 2:1.

The method of production of the claimed product differs from the method of production of the nearest structural analogue by that reaction of interaction is carried out at higher temperature (namely, at the temperature of 40 to 70 °C, while for the production of the known compound the temperature of interaction should not exceed 37 degrees, see Examples 5 and 6 of WO 96/08527), and by that the separation of impurities is made by extraction by spirits, and not by the diethyl ether.

The final product was washed by such organic solvent as the spirit for removal of unreacted substances and impurities.

The optimum initial concentration of para-benzoquinone in acetone makes usually 5-16 %. The optimum initial concentration of sodium thiosulfate in water makes usually 20-30 %.

The final product was normally washed 2-3 times by 5 volumes of the solvent.

In several experiments the preparation was obtained proceeding from hydroquinone which was oxidized by a known method, and then the formed para-benzoquinone was combined (without its intermediate separation) with the sodium thiosulfate.

A mixture of products, which is produced at interaction of para-benzoquinone and sodium thiosulfate, contains a various number of cyclolinear structures with 2 to 6 benzol rings. Content of this mixture can be various, it depends on interaction conditions - reagents ratio, temperature, duration of reaction and etc. Some data on this account are indicated below.
