[0070] Upon receipt of the compositions for the care of the oral cavity, it is sometimes necessary to add a certain amount of thickener to achieve the desired consistency or to stabilize or improve the functional properties of the composition.

[0072] in Addition to the above components, consider the composition in some embodiments, implementation of the present invention can contain many different optional ingredients of the numbers used in the tools for teeth, some of which are described below. These optional ingredients include, for example, without limitation, adhesive materials, foaming substances, flavorings, sweeteners, additional means for plaque removal, abrasives, dyes, known to specialists in this field.

[0073] the compositions of the present invention can be obtained by conventional methods known in the production of products to care for your mouth.

[0074] the Present invention, in one aspect, relate to methods of producing, comprises introducing into the oral cavity a safe and effective amount of the compositions to care for the oral cavity according to the present invention, for example, with a brush, with the aim of (i) reduce or inhibit formation of dental caries, (ii) reduce, repair or suppression precariously damage enamel detected, for example, by the method of quantitative induced light of fluorescence the (QLF) or electrical method for detection of caries (ECM), (iii) reduce or inhibit the demineralization and enhance remineralization of the teeth, (iv) reduce hypersensitivity of the teeth, (v) the reduction or suppression of gingivitis, (vi) improve healing capacity in respect of sores or cuts in the mouth, (vii) reduce levels of bacteria that form the acid (viii) to increase relative levels agrisolutions bacteria, (ix) inhibit the formation of microbial biofilms in the oral cavity, (x) raise and/or maintain the pH in the plaque on the level of at least pH 5.5 after provocation test with sucrose, (xi) reduce accumulation of plaque, (xii) reduce dry mouth, (xiii) the cleansing of the teeth and oral cavity (xiv) reduce erosion, (xv) whiten teeth, and/or (xvi) the destruction or suppression cariogenic bacteria.

[0075] the Oral compositions can also include one or more suitable solvents. The ability of any solid substance (dissolved substance) dissolved in any liquid substance (the solvent) is dependent on the physical properties of the dissolved substance and the solvent. In that case, when dissolved substances and solvents have similar physical properties, the solubility of the dissolved substance in the solvent will be higher. This situation corresponds to the well-known principle that "like dissolves under the service". Solvents may be characterized, in one extreme aspect as non-polar, lipophilic oil, while the other opposite end of the band in this classification system will correspond to the polar hydrophilic solvents. Oil solvents dissolve other nonpolar substances on the mechanism of the van der Waals interactions, while water and other hydrophilic solvents dissolve polar substances through ionic, dipole interactions, or interactions, based on the formation of hydrogen bonds. All known solvents can be listed in the form of a huge list covering connection, starting from the least polar, i.e. hydrocarbons, such as the Dean, to the polar solvent, which is water. Dissolved material will have the greatest solubility in solvents having similar polarity. Accordingly, in the case of medicines, which will have a minimal solubility in water, less polar solvents will provide increased solubility, if used, the solvent will have a polarity that is almost equivalent to that of the dissolved substance that will lead to the maximum solubility. Most drugs have an intermediate degree of polarity and, in the section communication show maximum solubility in solvents, such as propylene glycol or ethanol, which is much less polar than water. If the drug has a higher solubility in propylene glycol (e.g., 8 wt.%), than water (for example, 0.1 wt.%), the addition of water to propylene glycol will reduce the maximum amount of solute in solvent mixtures, in comparison with the use of pure propylene glycol. The addition of a solvent with low solubility to a solvent with a very good dissolving capacity will reduce the maximum solubility in the mixture, in comparison with the maximum solubility in the solvent with a very good dissolving capacity.

[0076] When the compounds included in the composition for the care of the oral cavity, the concentration of active ingredient in such compositions may be limited by the solubility of the active ingredient in the selected solvent and/or carrier. Not lipophilic drugs typically exhibit very low solubility in pharmaceutically acceptable solvents and/or carriers. For example, the solubility of some of the complexes porinovoi acid in water is less than 0,00025 wt.%. The solubility of the same complexes porinovoi acid may be less than about 2 ve is.% in propylene glycol or isopropylmyristate. In one embodiment of the present invention, for dissolving the compounds of formula I using solvent diethylene glycol-monotropy ether (DGME). It is believed that the complexes of porinovoi acid used in the present invention have a solubility of from about 10 wt.% to about 25 wt.% in DGME. In another embodiment of the present invention, use of alcohol DGME/water to dissolve the compounds of formula I. Dissolving ability DGME decreases with the addition of water; however, the system of co-solvents DGME/water can be designed in such a way as to maintain the desired concentration of active ingredient in the range of from about 0.1 wt.% to about 5 wt.%. Preferably, the active ingredient is present in an amount of from about 0.5 wt.% to about 3 wt.%, and more preferably, about 1 wt.%. This increased solubility reduces the likelihood of reducing the bioavailability caused by precipitation.

[0077] Liquid forms may include suitable aqueous or non-aqueous media together with buffers, suspendresume and crumbling agents, thickeners and the like means. Solid forms, such as creams or pastes or similar form, may include, for example, any of the following ingredients, water, oil, alcohol, or fat as a substrate, in which Oceanie with surface-active substance, polymers, such as polyethylene glycol, thickeners, solids and other Liquid or solid compositions may include improved system delivery, such as liposomes, microsome assay, microsponge etc. Additionally, these compounds can be delivered using a prolonged release system, such as semipermeable matrices of solid hydrophobic polymers containing therapeutic agent. There were various systems prolonged release materials that are well known to specialists in this field.

[0078] Below, the present invention is described using appropriate examples. These examples are given solely for the purpose of explanation and should not be construed as limiting the scope of the present invention, which is defined by the description and the claims.

EXAMPLE 1 Stability tools for cleaning teeth with a reduced water content

[0079] the Stability of the composition for cleaning teeth, containing the active ingredient, 3-hydroxypyridine-2-carbonyloxy-bis-(3-chloro-4-were)borane (COMPOUND 1)in a silica base was evaluated in the presence of different amounts of water. The composition had the following composition:

[0080] the Inclusion compound 1 in means for cleaning the teeth with a low water content increases the stability of the active ingredient, in comparison with the preparations for the care of teeth, including a higher amount of water. Such drugs with low water content have antibacterial and anti-inflammatory efficacy in vitro, which are equivalent to those for the positive control, Colgate Total® (Colgate Total®) with triclosan as an antibacterial agent.

[0081] the Difference in water content between these songs is very important. Drugs G series are characterized by the level of water activity (expressed as vapor pressure of water in the sample compared with the vapor pressure for pure water at the same temperature), equal to 0.75, whereas in the composition with 6% water content, this ratio is 0.25, and the composition without the addition of water it is 0,09. The stability of compound 1 over time in different compositions illustrated in the table below:

[0082] the Lowering of the water level in the medium for care of teeth has, apparently, a positive effect on the stability of compound 1 in the composition. After 2 months of storage under conditions of controlled room temperature (TCC) and at 40°C, is observed with lower % of reducible compounds 1 in compositions with a content of water is 0% and 6%, than in the standard composition G-series.

[0083] the Stability of these compounds was also evaluated by provocation option of adding hydrogen peroxide to the compound 1 in a molar ratio of 1:1. Compositions, which are characterized by sensitivity to decomposition of hydrogen peroxide, show less stability during storage. For example, the drug G-series was characterized by the reduction of compound 1 at the level of 59% after three months of storage at 40°C and at 35% recovery compound 1 after provocation with hydrogen peroxide, whereas a more stable composition used in this experiment as a positive control, showed an 87% level of recovery after three months of storage at 40°C and 85% recovery after provocation peroxide. (Note: the Positive control in this experiment was hee is automatic stable, but ineffective, according to the results of the test in vitro).

[0084] there has only been a 1% reduction in recovery connection 1 in the composition with 0% added water and 10% reduction in percent of its recovery in the composition with 6% added water. Both compositions showed a significantly reduced level of decomposition, in comparison with drugs G-series, which saw a 44% reduction reconnection 1.

[0085] based On the results of an experiment in provocation hydrogen peroxide and data in the two storage tracks, we can conclude that the decrease of water level in the medium for care of teeth improves the stability of the active component. Composition with 0% and 6% added water was investigated in the test, based on the measurement of growth inhibition A.viscosus, and it was shown that these compositions retain their antibacterial effectiveness. Composition with 0% added water was also evaluated in the test for anti-inflammatory activity by measuring the induction of PGE2, and it was shown that it is as effective as the positive control toothpaste Total® Total®) with triclosan, where the resulting value was <200 PG/ml PGE2 compared with a value of >1200 PG/ml for control, placebo, and approximately 400 PG/ml for G composition.

EXAMPLE 2 Compositions with high pH

[0086] the Composition for cleaning teeth, the content is asuu active ingredient, 3 hydroxypyridine-2-carbonyloxy-bis-(3-chloro-4-were)borane (COMPOUND 1)in a silica base was estimated at different levels of water content. It was shown that the stability of COMPOUND 1 in the means for cleaning the teeth depends on the pH of the composition. Specifically, there has been a significant increase in stability when the pH of cleaning the teeth is increased from 7 to 9, and there is no negative impact on antibacterial or anti-inflammatory efficacy of the composition.

[0087] the first composition known as the G-series, while the second composition was designated as composition with a low content of water, which corresponds to the preparations G-series, but includes 6% added water, as described in the example above. The main difference between the two compositions is the level of added water. Drugs G-series include approximately 32% of added water, while a drug with low water content includes 6% added water. In both compositions, the CONNECTION-level 1 is 0.75%. The pH was varied by adjusting the ratio of the amounts of sodium hydroxide and glycerol in the compositions described in the previous example, in order to obtain funds for brushing your teeth with pH values of 7, 8.5 and 9.

[0088] the results of the stability evaluation SOEDINENIYA under accelerated stability testing at 40°C are shown in table 2. Preparations for G-series, the percentage recovery CONNECTION 1 after three months of storage under conditions of rapid test evaluation of stability by approximately 30% higher in compositions with a pH of 8.5 and pH 9, in comparison with a composition having a pH of 7. The same trend was observed in compositions with low water content. These results demonstrate the marked improvement in the stability of COMPOUND 1 as a result of increasing pH for cleaning teeth. Although pH is a major determinant of the decline in water level, apparently, also has a positive effect on the stability of COMPOUNDS COMPOUND 1 in the composition.

[0089] After two months of storage in controlled conditions at room temperature and at 40°C, we observed less drop % recovery COMPOUND 1 in compositions with 0% and 6% added water than in the drug G-series:

[0090] To further study the effect of pH on the stability of COMPOUND 1, was prepared in a series of paste-like products with pH values ranging from 5.7 to 9. The paste was kept at 60°C for two weeks to get accelerated results on the stability of compositions depending on the pH. In preparations G-series, the percentage of the recovered COMPOUND 1 decreases with decreasing pH from p 9 to pH 7.5, but increases when the change in pH from pH 7 to pH of 5.7. When using a substrate with low water content, percent recovered COMPOUND 1 decreases with the change of pH values from pH 9 to pH of 5.7. Although stability at acidic pH values is different for the two different bases in the investigated compositions, at pH 9 has the highest percentage of recovered COMPOUNDS 1 in both compositions. In addition, it was shown that the ratio of the isomers of COMPOUND 1 are also strongly depends on pH. At pH 9, the CONNECTION 1 is present only in its polar form, and the number of polar isomer increases with decreasing pH for cleaning teeth. A similar trend was observed in case of liquid funds for the care of teeth.

[0091] In Fig. 1 illustrates the percent recovery of COMPOUND 1 after two weeks of storage at 60°C as a function of the pH of the composition for drugs (a) basis consistent with the G-series, and (b) with a base containing a reduced level of water.

[0092] As a means for care of teeth contains many components, it is important to understand what is determined in this case, the observed correlation between the stability of COMPOUNDS 1 and pH: any ingredient in means for cleaning the teeth or it is a response of the CONNECTION 1 on the pH. In this regard, conducted a study of the effect of pH on OBEDINENIE 1 simple solution, including 50/50 acetonitrile/water. The result is shown in Fig. 2. In this study, produced a series of samples with pH values in the range from 9 to 6 and kept at 70°C for one day. The solution at pH 9 was characterized by the highest percentage of recovered COMPOUNDS 1. It was also shown that at pH 9 there is only one non-polar isomer and that the ratio of the nonpolar rotamer to polar rotamer decreases with decreasing pH, the same trend was demonstrated in the case of cleaning the teeth. These results indicate that non-polar rotamer COMPOUND 1 significantly less sensitive to degradation and that the ratio of nonpolar to polar isomer isomer depends on pH. Thus, the obtained results allow to explain the observed increase % recovery COMPOUND 1 in the compositions at a pH of 9 and 8.5 in comparison with a composition having a pH of 7. Differences between the stability of COMPOUND 1 at lower pH values in the two compositions with different bases reflects, apparently, the ability of the ingredients of the composition to partially stabilize the polar rotamer.

[0093] In Fig. 2 shows the percentage of recovery COMPOUND 1 in solution containing 50/50 acetonitrile/water as a function of pH, after 1-day storage at 70°C.

[0094] Protivovospalitel the capacity effect of COMPOUNDS 1, apparently unaffected by the increase in the pH of the composition. As preparations G-series, and composition with reduced water content at pH 7 and 9, are functioning well, the evaluation of suppression marker anti-inflammatory activity of PGE2. Antibacterial effect of COMPOUND 1, as measured by growth inhibition A.viscosus, comparable to those corresponding to the paste with a pH of 7, as well as commercial toothpaste high quality.

[0095] the Deposition of COMPOUND 1 on hydroxyapatite disk (HAP) significantly increases with increasing pH. Although the release of COMPOUND 1 at pH 9 is only 29%, this is equivalent to the number of CONNECTIONS 1 released from the compositions G-pH 7 and G-pH 9.

EXAMPLE 3 - the Effectiveness of the CONNECTION 1 on the inhibition of bacterial growth in the oral cavity

[0096] Determined the minimum inhibitory concentration of COMPOUND 1 against the normal bacteria of the oral cavity, which is shown in the table below. Ethanol was used as the carrier.

EXAMPLE 4 - Solubilization of Compounds 1

a. Solubilization using copolymers of ethylene glycol and propylene glycol

[0097] the Poor solubility of compound A creates certain problems in the manufacture of the composition. The solubility of this compound in water is less than 100 ppm, and solubility in pexeva the oils commonly used to solubilize the active ingredients) is less than 0.5%. The authors found that the use of copolymers of polyethylene glycol and polypropylenglycol allows to achieve solubilization of the compound 1. So, Fluraflo L4370 (BASF) solubilities 1% of compound 1 (wt.%). It is necessary to mix the solution at low heat for complete solubilization of the active ingredient. It turns a cloudy solution, which corresponds to the nature of the Fluraflo L4370. Next, a 1% solution of compound 1 in Fluraflo L4370 was diluted in the ratio 1:1 using 1.5% of LTOs in water to obtain a clear solution consisting of 0.5% AN0128, 0,75% LTOs and 50% Fluraflo L4370 in the water. Similar results were obtained when using Fluracare LI220.

[0098] Next, a solution containing 0.5% AN0128, 0,75% LTOs and 50% Fluraflo L4370 in water, were analyzed in the test for the destruction of biofilms. The resulting percentage reduction in comparison with a negative control was 65%, indicating that compound 1 retains its antibacterial activity by solubilization in Fluraflo L4370.

b. Solubilization using triblock-copolymer

[0099] the Authors also found that the triblock copolymer used as surfactants, F127 can further improve the solubilization of the compound 1. In the experimental liquid compositions funds for care of teeth (table 3), the connection 1 over time is not fully dissolved, what followed, and the evaluation results according to the method of deposition and crystallization after a certain period of time. After adding 5% F127, experimental liquid compositions funds for care of teeth (table 4) remained transparent. This means that the triblock-copolymer surfactant F127 allows more solubilisate connection 1 and, in this regard, can be used in the compositions.

C. Solubilization using PEG

[0100] Additionally, the authors found that low molecular weight polyethylene glycol 300 (PEG 300) (Dow Chemical Company) solubilities 10% of compound 1 (wt.%). In this case, it is necessary to mix the solution at low heat for complete solubilization of the connection. The resulting solution was clear with a slightly yellow tint, which is determined by the color of the connection 1. The authors showed that PEG 600 may also solubilisate connection 1. In this regard, the authors concluded that solvents containing oligomers and/or polymers of ethylene glycol, can solubilisate connection 1 and can be used to obtain the composition.

[00101] a Solution of 2% of compound 1 in PEG 300 was diluted in the ratio 1:1 2% LTOs in water to obtain a solution consisting of 1% compound 1, 1% LTOs, 50% PEG 300 in the water, which was analyzed in the test for the destruction of biofilms. The achievable per cent decline in comparison with negative control was 76%, which indicated that compound 1 retains its antibacterial activity by solubilization in PEG 300.

[00102] the Properties of the compound 1 in combination with other excipients were additionally evaluated by dilution of a solution of compound 1 in PEG 300 other solvents, such as propylene glycol and glycerin, in different proportions. A solution containing 1% of compound 1 in 19% PEG 300 and 80% propylene glycol, was transparent. Further, this races the thief was diluted in the ratio 1:1 using 1% LTOs in water to obtain a solution, consisting of 0.5% of the compound 1, 0.5% of LTOs, and 9.5% PEG 300 and 40% propylene glycol in water, which is then analyzed in the test for the destruction of biofilms. The achievable per cent decline in comparison with negative control was 80%. The results show that compound 1 retains its antimicrobial activity in solution of a mixture of solvents. Similar results were obtained using PEG and glycerin.

EXAMPLE 5 - the Buffer composition

[00103] Received two compositions connection 1 with a pH of 7.2, one of which was prepared in phosphate buffer, and one did not contain a buffer, and determined the degree of decomposition of the compounds 1 through 14 days. Although explicit decomposition was noted in both compositions, the slope of the curve describing the rate of decomposition of compound 1 in the buffer composition was below 3.3 times than the composition without the buffer.

EXAMPLE 6 Effect of gantrez (Gantrez)

[00104], it Was shown that adding gantrez in the liquid compositions of compound 1 increases the activity of this compound, according to the test on the biofilm. The composition had the following composition:

[00105] the Authors determined the activity of these funds for the care of teeth in the test for inhibition of biofilm formation of A.viscosus, organism, which has been shown to be relatively resistant to compound 1, in comparison with many other plaincourault what they bacteria. The composition of the G7 had a very good efficiency, causing with this test the inhibition of the formation of biofilms on the same level as commercially available toothpaste Total® Total®) with triclosan, while the G5 was only slightly better than the control. Thus, adding gantrez (Gantrez) (copolymer metilfenidato ether and maleic acid or copolymer MVP/MK (PVM/MA)substantially increases the activity of compound A in the test for suppression film forming A. viscosus.

EXAMPLE 7 Optimization tools to care for your teeth

Table 8 describes three songs toothpaste silica containing compound 1, where the number of components is given in wt.% (w/w), the water level is so adjusted to compensate for the difference in the content of glycerol:

[00106] The compositions investigated in the test for inhibition of growth of A. viscosus within 24 hours, where the growth of the organism was assessed by a measure of the optical density at 610 nm. The specified value after 24 hours water, or the composition G without compound 1 was >1,4; it was <0.2 for the composition of G with connection 1. This indicates very good performance against that of the studied organism, the same or even better than the positive control, commercially available toothpaste Total® Total®) with triclosan. Similarly, in the test on davlenie education biofilms from different species of microorganisms, the average value of SOME of the compositions G and Total® Total®) was <2 (SD 0), in comparison with the value of 1.1×10⁹(Standard deviation of 1.5×10⁸demonstrating the fact that toothpaste containing compound 1, is able to inhibit the formation of biofilms.

EXAMPLE 8 - using a chelating agent

[00107] it Was observed that the means for brushing your teeth on a silica basis quickly changes its color from white to yellow when adding 0.25 to 1% of compound 1 at the final stage of preparation of the composition. This color change occurs both in the presence of an antioxidant, and in the absence of an antioxidant, such as bottled hydroxytoluene (BHT), vitamin E or vitamin C. However, the addition of small amounts of metal chelating agent returns the color specified funds for brushing your teeth to their original white color. Effective for this purpose chelating agents include 0.5% pyrophosphate is tetranitride (TSPP), and pyrophosphate is tetracene, ethylenediaminetetraacetic acid, etilenditiodiuksusnoi acid, sodium pyrophosphate, sodium tripolyphosphate, potassium tripolyphosphate, sodium hexametaphosphate, sodium and citric acid.

EXAMPLE 9 - Using antioxidants

[00108] esters of porinovoi acid can be oxidized by molecular oxygen or peroxides, which may be formed from esters, t is such as PEG, under the action of atmospheric oxygen. These highly oxidized species may act to link the carbon-boron, leading to its cleavage and formation of the respective derivatives Bronevoy acid and phenolic derivatives. The oxidation products are inactive. Adding oxygen scavengers and/or antioxidants, such as vitamin C (ascorbic acid), vitamin E (α-tocopherol) or 2,6-di-tert-butyl-4-METHYLPHENOL (bottled hydroxytoluene or BHT) removes the oxygen and reduces the level of peroxides, already present in the composition. The amount of antioxidant must not exceed the level of ester porinovoi acid used in this composition.

[00109] Compared the stability of the three compositions of compound 1, where these compositions were identical except that one song does not contain any antioxidants, the second contained α-tocopherol, and the third composition contained sodium ascorbyl phosphate. The destruction of the compounds of formula I were to be reduced significantly in the composition containing sodium ascorbyl phosphate, and an even weaker decomposition was observed in compositions containing α-tocopherol. This result shows that the use of antioxidant improves the stability of compound 1 in the composition.
