Description

The invention relates to the use of 4-oxo-4H-pyran or 4-oxo-1,4-dihydropyridine derivatives as protein-adhesive active compounds, in particular as skin- or hair-adhesive and/or skin- or hair-binding UV absorbers, and for protection of the skin, of the hair or of the nails against damage caused by ultraviolet radiation, to specific 4-oxo-4H-pyran or 4-oxo-1,4-dihydropyridine derivatives, to the preparation thereof and to preparations comprising same. The invention furthermore relates to the use of the structural unit 4-oxo-4H-pyran-3-O-yl or 4-oxo-1,4-dihydropyridin-3-O-yl as linker for the functionalisation of protein-containing matrices.


A preferred area of application of the 4-oxo-4H-pyran or 4-oxo-1,4-dihydropyridine derivatives of the formula I, as described below, is UV protection or in other words protection of the skin, of the hair and of the nails, the so-called protein-containing matrices, against damage which can be caused by ultraviolet radiation or in other words for protection against UV-induced damage of the skin, of the hair and of the nails. Damage which can be caused by ultraviolet radiation is, for example, sun allergy, the generation of erythemas or sunburn, the formation of skin cancer and a weakening of the immune system, in particular of the immune system of the skin. The human skin is naturally also subject to certain ageing processes, some of which are attributable to intrinsic processes (chronoageing) and some of which are attributable to exogenous factors (environmental, for example photoageing). Photoageing is accompanied by a loss of the elasticity of the skin and pigment spots.


Ultraviolet radiation is, for example, ultraviolet solar radiation or sun-like light. Sun-like light is taken to mean radiation in a spectral composition analogous to solar radiation or sunlight. Sun-like light of this type can be generated, for example, by a solar simulator or used in solaria, where the spectral composition of the solaria radiation is not exactly equal to sunlight. Accordingly, sun-like light is also intended to be taken to mean light which is at least partly equal to the spectral composition of sunlight or which develops a sunlight-like effect.


The exogenous factors include, in particular, sunlight or artificial radiation sources having a comparable spectrum and compounds which may be formed by the radiation, such as undefined reactive photoproducts, which may also be free-radical or ionic.


A multiplicity of organic and inorganic UV filters and antioxidants is known which absorb UV radiation and are able to scavenge free radicals. They are thus capable of protecting the human skin. These compounds catalyse the transformation of UV light into heat.


Owing to poor skin adhesion, however, the duration of protection is limited, in particular since conventional UV absorbers or UV filters can be washed off very easily, for example by sweat or water.


WO 2006/018104, for example, discloses a strategy for derivatising UV absorbers, UV filters or self-tanner substances in such a way that they are able to bond covalently to the stratum corneum of the epidermis via a reactive moiety and thus functionalise the skin with the UV absorber, UV filter or self-tanner. For effective binding of proteins and amino acids of the outer skin layers, it is necessary for the corresponding UV absorbers, UV filters or self-tanners to have the highest possible reactivity of their moieties which are capable of binding.


Ascorbic acid derivatives, in particular of ascorbic acid derivatives which are substituted in the 6- and/or 5-position by UV chromophores, are known, for example, from WO 2008/017346. The preparation and storage of these compounds take place under inert conditions, for example with exclusion of oxygen, since the substances are oxidation-sensitive.


There is therefore an increasing demand for skin-tolerated and oxidation-stable compounds which are capable of functionalising protein-containing matrices and can be incorporated in a suitable manner into cosmetic or pharmacological preparations.


Surprisingly, it has now been established that the compounds of the formula I, as described below, are eminently suitable as protein-adhesive active compounds or in other words for the functionalisation of protein-containing matrices. The term protein-adhesive active compound is taken to mean an active compound which binds to a protein-containing matrix owing to at least one adhesion. Preferred matrices here are skin, hair and/or nails, where the general principle can also be applied to the functionalisation of synthetic polymer matrices containing amino groups or thiol groups, isolated proteins or gelatine. The products formed by adhesion and/or binding to such matrices can be used as, for example, cosmetic active compounds for the preparation of cosmetic compositions. The forces for adhesion which effect the cohesion have not been researched fully, and consequently there are various adhesion theories which encompass both mechanical adhesion owing to physical-mechanical forces and specific adhesion owing to chemical and physical forces. It is, for example, possible for the compounds of the formula I, as described below, to interact physically with the matrix molecules, as described above, due to their amphiphilicity or to form a covalent bond to an amino or thiol group of the matrix. The protein-adhesive active compounds can accordingly interact physically or form a covalent bond with the matrix. Due to the amphiphilicity, the compounds of the formula I, as described below, also have surface-active properties. The compounds of the formula I, as described below, are preferably skin- or hair-adhesive and/or skin- or hair-binding UV absorbers.


The compounds of the formula I, as described below, are likewise film-forming active compounds. Owing to the homogeneous distribution due to uniform surface adhesion and/or binding, an essential advantage, besides the long-lasting adhesion to the matrix, is that less active substance is required than in the case of the use of conventional UV absorbers.


The compounds of the formula I, as described below, are likewise suitable stabilisers for preparations, in particular cosmetic preparations or medicinal products, against UV radiation.


Compounds of the formula I according to the invention, as described below, are suitable as antiglycation agents and counter the formation of AGEs (advanced glycation end products).


Accordingly, the invention relates firstly to the use of compounds of the formula I,

This use is preferably a non-therapeutic use.


The invention furthermore also relates to the non-therapeutic use of compounds of the formula I,

For the purposes of the invention, the compounds of the formula I, are defined in such a way that they are also taken to mean pharmaceutically or cosmetically usable derivatives, salts, hydrates, solvates, precursors of the compounds, tautomers and optically active forms (such as, for example, stereoisomers, diastereomers, enantiomers, racemates). Solvates of the compounds are taken to mean adductions of inert solvent molecules onto the compounds which form owing to their mutual attractive force. Solvates are, for example, mono- or dihydrates or alcoholates. Pharmaceutically or cosmetically usable derivatives are taken to mean, for example, the salts of the compounds according to the invention. The compounds of the formula I can form cis/trans isomers or tautomers. The formula I encompasses all these forms.


A base of the formula I can be converted into the associated acid-addition salt using an acid, for example by reaction of equivalent amounts of the base and the acid in an inert solvent, such as ethanol, and subsequent evaporation. Suitable acids for this reaction are, in particular, those which give physiologically acceptable salts.


On the other hand, acids of the formula I can be converted into the corresponding metal salts, in particular alkali metal or alkaline-earth metal salts, or into the corresponding ammonium salts using bases (for example sodium hydroxide or potassium hydroxide or sodium carbonate or potassium carbonate).


In accordance with the invention, compounds of the formula I, as described above, are preferably used if

The preparation of the compounds of the formula I, as described above, can be carried out here by methods known per se to the person skilled in the art from the literature. The reaction conditions for esterifications or etherifications are standard prior art and the selection of the suitable reaction conditions belongs to the standard expert knowledge of the person skilled in the art of synthesis.


The invention likewise relates to a process for the preparation of compounds of the formula I, as described above, characterised in that


a) a compound of the formula XVI




embedded image


where E, R2, R3 and R4 have a meaning indicated above,


is reacted with a compound of the formula XVII





R1-M  XVII,


in which R1 has one of the meanings described above, where the part-formulae XI and XII are excluded, and


M denotes alkali metal or alkaline-earth metal cation or H or


b) a compound of the formula XVI




embedded image


where E, R2, R3 and R4 have a meaning indicated above,


is reacted with an acid halide or an active ester of the free acids derived from the formulae II, III, IV, V, VI, VII, XI, XII and XIV.


Some of the compounds of the formula XVI are commercially available, for example 3-hydroxy-2-methyl-4-pyranone, or can be prepared by known literature methods, for example based on R. Suzuki et al, Heterocyles, 1977, 6(9-10), 1575-80 or A. Fassihi et al, European Journal of Medicinal Chemistry, 2009, 44(5), 2145-2157).


Some of the compounds of the formula XVII or the free acids derived from the formulae II, III, IV, V, VI, VII, XI, XII and XIV are commercially available, for example p-methoxycinnamic acid, p-hydroxycinnamic acid, 2-(4-dimethylamino-2-hydroxybenzoyl)benzoic acid or 2-(4-methoxy-2-hydroxy-benzoyl)benzoic acid, or can be synthesised by methods which are described, for example, in the standard works, such as Houben-Weyl, Methoden der organischen Chemie [Methods of Organic Chemistry], Georg-Thieme-Verlag, Stuttgart, to be precise under reaction conditions which are known and suitable for the said reactions. Use can also be made here of variants known per se which are not mentioned here in greater detail.


The ether formation by reaction of compounds of the formula XVII in which R1 conforms to the part-formulae VIII, IX, X, XIII, XIV or XV and in which M=H with a compound of the formula XVI, as described above, preferably takes place in the presence of triphenylphosphine and diisopropyl azodicarboxylate, in an inert solvent, for example a halogenated hydrocarbon, such as dichloromethane, an ether, such as tetrahydrofuran or dioxane, an amide, such as DMF or dimethylacetamide, a nitrile, such as acetonitrile, in dimethyl sulfoxide or in the presence of these solvents, at temperatures between about −10 and 40, preferably between 0 and 30°. The reaction time is between a few minutes and several days, depending on the conditions used.


If an acid halide or an active ester of the free acid derived from the formulae II, III, IV, V, VI, VII, XI, XII and XIV are employed for the synthesis of the compounds of the formula I in which R1 corresponds to one of the moieties II, III, IV, V, VI, VII, XI, XII and XIV,


a classical nucleophilic substitution takes place. The reaction conditions of a nucleophilic substitution are adequately known to the person skilled in the art of synthesis.


Preferred acid halides are acid chlorides.


If a compound of the formula XVI, as described above, for example 3-hydroxy-2-methyl-4-pyranone, is reacted with a compound of formula XVII in which M=H and R1 preferably conforms to the part-formula II, III, IV, V, VI, VII or XIV, the coupling reaction is preferably carried out in the presence of a dehydrating agent, for example a carbodiimide, such as dicyclohexylcarbodiimide (DCC), N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (EDC) or diisopropylcarbodiimide (DIC), furthermore, for example, propanephosphonic anhydride (cf. Angew. Chem. 1980, 92, 129), diphenylphosphoryl azide or 2-ethoxy-N-ethoxycarbonyl-1,2-dihydroquinoline, in an inert solvent, for example a halogenated hydrocarbon, such as dichloromethane, an ether, such as tetrahydrofuran or dioxane, an amide, such as DMF or dimethylacetamide, a nitrile, such as acetonitrile, in dimethyl sulfoxide or in the presence of these solvents, at temperatures between about −10 and 40, preferably between 0 and 30°. Depending on the conditions used, the reaction time is between a few minutes and several days.


Instead of compounds of the formula XVII, as defined above, it is also possible to employ derivatives of the formula XVII, preferably a pre-activated carboxylic acid or a carboxylic acid halide, a symmetrical or mixed anhydride or an active ester. Radicals of this type for activation of the carboxyl group in typical acylation reactions are described in the literature (for example in the standard works, such as Houben-Weyl, Methoden der organischen Chemie [Methods of Organic Chemistry], Georg-Thieme-Verlag, Stuttgart). Activated esters are advantageously formed in situ, for example by addition of HOBt (1-hydroxybenzotriazole) or N-hydroxy-succinimide.


The reaction is generally carried out in an inert solvent, in the case of the use of an acid halide in the presence of an acid-binding agent, preferably an organic base, such as triethylamine, dimethylaniline, pyridine, dimethyl-aminopyridine or quinoline.


The addition of an alkali or alkaline-earth metal hydroxide, carbonate or bicarbonate or of another salt of a weak acid of the alkali or alkaline-earth metals, preferably of potassium, sodium, calcium or caesium, may also be favourable.


The compounds of the formula I described are capable of adsorbing onto and/or binding to protein-containing textiles or textile fibres and thus developing their action, in each case depending on the radical R1, for example UVB protection. Undesired material damage is thus reduced.


The compounds of the formula I according to the invention, as described above or as preferably described, are oxidation-stable and exhibit a reduced yellow colouration or no yellow colouration on storage.


The compounds of the formula I according to the invention, as described above or as preferably described, also have, for example, anti-ageing effects, i.e. they serve, for example, for skin regeneration and cause wrinkle reduction of (light)-aged skin, they furthermore increase, for example, the skin relief density, have a skin-taughtening action or strengthen, for example, the dermis-epidermis bond (papilla index). They protect the skin against UV-induced damage or they have, for example, a skin-bleaching action. They have, for example, an antibacterial action, i.e. they can reduce sweat odour or improve the skin appearance in the case of skin impurities and/or acne.


Compounds of the formula I according to the invention, as described above, are likewise suitable as anti-glycation agents and counter the formation of AGEs (advanced glycation end products).


Compounds according to the invention are suitable as contrast reduction agents, i.e. they may be able to lighten dark skin areas or darken light skin areas.


The compounds of the formula I according to the invention, as described above or as preferably described, are capable of bonding to hair and can thus suppress hair damage caused by UV light or by oxidation, in particular with respect to colour and morphology. For example, protection can thus be provided against bleaching of the hair.


The compounds of the formula I according to the invention, as described above or as preferably described, are capable of bonding not only to nitrogen-containing, but also to sulfur-containing hair functionalities, such as, for example, to thiolic groups.


The present invention furthermore relates to a preparation comprising at least one compound of the formula I, as described above or described as preferred or described as preferred individual compounds, where the compounds 2-methyl-4-oxo-4H-pyran-3-yl (E)-3-(4-hydroxyphenyl)acrylate or 2-methyl-4-oxo-4H-pyran-3-yl 2-hydroxybenzoate are excluded.


The invention furthermore relates to a preparation comprising 2-methyl-4-oxo-4H-pyran-3-yl (E)-3-(4-hydroxyphenyl)acrylate or 2-methyl-4-oxo-4H-pyran-3-yl 2-hydroxybenzoate, a cosmetic, dermatological or pharmacologically tolerated vehicle and at least one further active compound selected from the group UV filters, antioxidants, vitamins, anti-ageing active compounds, anticellulite active compounds, self-tanning substances, antipigmentation substances or skin-lightening substances.


Owing to the surface-adhesive, film-forming property of compounds according to the invention, further active compounds present in the preparation according to the invention can be protected particularly well against oxidative decomposition in preparations according to the invention, both before and during use thereof. Further active compounds of this type which are present in the composition according to the invention are, for example, dyes, in particular hair dyes and hair colorants, or other oxidation-sensitive substances, such as unsaturated fatty acids, squalene, vitamins, antioxidants, self-tanning substances, such as, for example, dihydroxyacetone, retinoids, such as, for example, retinol.


Furthermore, further active compounds present in the compositions according to the invention are optimally distributed on the action surface owing to the film-forming property of substances according to the invention and are thus enhanced in their action performance.


Compositions according to the invention can therefore be used, for example, as hair-treatment compositions for the

    • vitalisation of hair and/or
    • stimulation of energy metabolism in hair follicles and/or
    • activation of hair follicles and/or
    • promotion or enhancement of hair growth and/or

    • retardation of the ageing process of keratinic fibres, in particular human hair, and/or
    • improvement of the restructurability of keratinic fibres, in particular human hair, and/or
    • reduction of the decrease in elasticity of keratinic fibres, in particular human hair, in the case of damage due to atmospheric effects.

For example, it is also possible to employ mixtures of various metal oxides, such as, for example, titanium dioxide and cerium oxide, with and without aftertreatment, such as, for example, the product Sunveil A from Ikeda. In addition, it is also possible to use mixtures of aluminium oxide, silicon dioxide and silicone-aftertreated titanium dioxide, zinc oxide mixtures, such as, for example, the product UV-Titan M261 from Sachtleben, in combination with the UV protection agent according to the invention.


These inorganic UV filters are generally incorporated into the preparations in an amount of 0.1 percent by weight to 25 percent by weight, preferably 2% by weight—10% by weight.


By combination of one or more of the said compounds having a UV filter action, the protective action against harmful effects of the UV radiation can be optimised.


All the said UV filters can also be employed in encapsulated form. In particular, it is advantageous to employ organic UV filters in encapsulated form. It may therefore be preferred for one or more of the above-mentioned UV filters to be in encapsulated form. It is advantageous here for the capsules to be so small that they cannot be observed with the naked eye. In order to achieve the above-mentioned effects, it is furthermore necessary for the capsules to be sufficiently stable and the encapsulated active compound (UV filter) only to be released to the environment to a small extent, or not at all.


However, the protective action against oxidative stress or against the effect of free radicals can be improved further if the compositions or preparations according to the invention comprise one or more further antioxidants, the person skilled in the art being presented with absolutely no difficulties in selecting antioxidants which act suitably quickly or with a time delay.


There are many proven substances known from the specialist literature which can be used as antioxidants, for example amino acids (for example glycine, histidine, tyrosine, tryptophan) and derivatives thereof, imidazoles (for example urocanic acid) and derivatives thereof, peptides, such as D,L-carnosine, D-carnosine, L-carnosine and derivatives thereof (for example anserine), carotinoids, carotenes (for example α-carotene, β-carotene, lycopene) and derivatives thereof, chlorogenic acid and derivatives thereof, lipoic acid and derivatives thereof (for example dihydrolipoic acid), aurothioglucose, propylthiouracil and other thiols (for example thioredoxin, glutathione, cysteine, cystine, cystamine and the glycosyl, N-acetyl, methyl, ethyl, propyl, amyl, butyl and lauryl, palmitoyl, oleyl, γ-linoleyl, cholesteryl and glyceryl esters thereof) and salts thereof, dilauryl thiodipropionate, distearyl thiodipropionate, thiodipropionic acid and derivatives thereof (esters, ethers, peptides, lipids, nucleotides, nucleosides and salts), and sulfoximine compounds (for example buthionine sulfoximines, homo-cysteine sulfoximine, buthionine sulfones, penta-, hexa- and heptathionine sulfoximine) in very low tolerated doses (for example pmol to μmol/kg), and also (metal) chelating agents (for example α-hydroxyfatty acids, palmitic acid, phytic acid, lactoferrin), α-hydroxy acids (for example citric acid, lactic acid, malic acid), humic acid, bile acid, bile extracts, bilirubin, biliverdin, EDTA, EGTA and derivatives thereof, unsaturated fatty acids and derivatives thereof, vitamin C and derivatives (for example ascorbyl palmitate, magnesium ascorbyl phosphate, ascorbyl acetate), tocopherols and derivatives (for example vitamin E acetate), vitamin A and derivatives (for example vitamin A palmitate), and coniferyl benzoate of benzoin resin, rutinic acid and derivatives thereof, α-glycosylrutin, ferulic acid, furfurylideneglucitol, carnosine, butylhydroxytoluene, butylhydroxyanisole, nordihydroguaiaretic acid, trihydroxybutyrophenone, quercetin, uric acid and derivatives thereof, mannose and derivatives thereof, zinc and derivatives thereof (for example ZnO, ZnSO4), selenium and derivatives thereof (for example selenomethionine), stilbenes and derivatives thereof (for example stilbene oxide, trans-stilbene oxide).

The compositions or compositions according to the invention may comprise vitamins as further ingredients. The cosmetic compositions according to the invention preferably comprise vitamins and vitamin derivatives selected from vitamin A, vitamin A propionate, vitamin A palmitate, vitamin A acetate, retinol, vitamin B, thiamine chloride hydrochloride (vitamin B1), riboflavin (vitamin B2), nicotinamide, vitamin C (ascorbic acid), vitamin D, ergo-calciferol (vitamin D2), vitamin E, DL-α-tocopherol, tocopherol E acetate, tocopherol hydrogensuccinate, vitamin K1, esculin (vitamin P active compound), thiamine (vitamin B1), nicotinic acid (niacin), pyridoxine, pyridoxal, pyridoxamine (vitamin B6), pantothenic acid, biotin, folic acid and cobalamine (vitamin B12), particularly preferably retinol, nicotinamide, vitamin A palmitate, vitamin C and derivatives thereof, DL-α-tocopherol, tocopherol E acetate, nicotinic acid, pantothenic acid and biotin, very particularly preferably retinol or nicotinamide.

Bioflavonoid-containing extracts are, for example, ginkgo biloba or emblica.


Known anti-ageing substances are also chromones, as described, for example, in EP 1508327, or retinoids, for example retinol (vitamin A), retinoic acid, retinaldehyde or also synthetically modified compounds of vitamin A.


The chromones and retinoids described are simultaneously also effective anti-cellulite active compounds. A likewise known anti-cellulite active compound is caffeine.


Suitable anti-ageing active compounds are, for example, the products marketed by Merck 5,7-dihydroxy-2-methylchromone, marketed under the trade name RonaCare®Luremine or the products Ronacare®Isoquercetin, Ronacare®Tiliroside or Ronacare®Cyclopeptide 5.


Furthermore, the preparations according to the invention may comprise at least one self-tanning agent as further ingredient.


Advantageous self-tanning agents which can be employed are, inter alia: 1,3-dihydroxyacetone, glycerolaldehyde, hydroxymethylglyoxal, γ-dialdehyde, erythrulose, 6-aldo-D-fructose, ninhydrin, 5-hydroxy-1,4-naphtoquinone (juglone) or 2-hydroxy-1,4-naphtoquinone (lawsone). Very particular preference is given to 1,3-dihydroxyacetone, erythrulose or a combination thereof.


Preparations having self-tanner properties, in particular those which comprise dihydroxyacetone, tend towards malodours on application to the human skin, which are thought to be caused by degradation products of dihydroxyacetone itself or by products of side reactions and which are regarded as unpleasant by some users. It has been found that these malodours are prevented on use of formaldehyde scavengers and/or flavonoids. The preparation according to the invention comprising at least one self-tanner may therefore preferably also comprise formaldehyde scavengers and optionally flavonoids in order to improve the odour.


The preparations may also comprise one or more further skin-lightening active compounds or synonymously antipigmentation active compounds. Skin-lightening active compounds can in principle be all active compounds known to the person skilled in the art. Examples of compounds having skin-lightening activity are hydroquinone, kojic acid, arbutin, aloesin niacinamide, azelaic acid, elagic acid, tranexamic acid, potassium 4-methoxysalicylate, mulberry tree extract, magnesium ascorbyl phosphate, liquorice extract, emblica, ascorbic acid or rucinol, as well as substances as described under WO2007121845. Preparations of this type enable, for example, the skin contrast between light and dark areas to be reduced. The skin thus appears to be more homogeneously coloured. The appearance is younger than the strongly contrasted skin.


Suitable preparations are those for external application, for example can be sprayed onto the skin as cream or milk (O/W, W/O, O/W/O, W/O/W), as lotion or emulsion, in the form of oily-alcoholic, oily-aqueous or aqueous-alcoholic gels or solutions. They can be in the form of solid sticks or formulated as an aerosol. Administration forms such as capsules, dragees, powders, tablet solutions or solutions are suitable for internal use.

They are preferably employed in 0.5 to 50% by weight, preferably between 5 and 30% by weight, based on the composition as a whole. In general, softeners can be classified in classes, such as, for example, the category of the esters, fatty acids or fatty alcohols, polyols, hydrocarbons and oils containing at least one amide structural unit.

The invention furthermore also relates to the use of the structural unit of the formula I-1




embedded image


in which R2, R3, R4 and E have a meaning indicated in the case of the compounds of the formula I or a meaning preferably indicated, as linker for the functionalisation of protein-containing matrices, where the symbol * denotes the linking site in the form of a covalent single bond to a molecule which is intended to be adsorbed onto or covalently bonded to the matrix.


The structural unit of the formula I-1 is essential for the adhesion and/or binding of the compounds of the formula I, as described above. The nature of the covalent single bond by means of which the molecule to be adsorbed or bonded is bonded to the linker is independent of the adhesion and/or binding to the protein-containing matrix. This linker of the formula I-1 provides molecules of this type, for example active compounds, with a surface-adhesive film-forming property and thus enables them to be adsorbed very uniformly onto suitable surfaces. Thus, for example, active compounds having a variety of structures can be bonded to the protein-containing matrix, in particular to the skin, hair and/or nails. This results, for example, in immobilisation of the desired active compounds, for example of UV absorbers, UV filters, dyes, such as, for example, fluorescent dyes for marking tissue, or enables controlled release of active compound, for example for pharmacological, antimicrobial, fungicidal, herbicidal, insecticidal or cosmetic active compounds or for X-ray contrast compositions.


This linker of the formula I-1 likewise provides molecules of this type, for example the class of organic UV absorbers or UV filters, with an amphiphilic property and they thus have a surface activity which, although not characterising them as a surfactant, does, however, help the active compounds to attain a property profile which differs from the property profile of classical, in particular oil-soluble, organic UV absorbers or UV filters.


Even without further comments, it is assumed that a person skilled in the art will be able to utilise the above description in the broadest scope. The preferred embodiments and examples should therefore merely be regarded as descriptive disclosure which is absolutely not limiting in any way. The complete disclosure content of all applications and publications mentioned above and below are incorporated into this application by way of reference. The percent by weight ratios of the individual ingredients in the preparations of the examples expressly belong to the disclosure content of the description and can therefore be utilised as features.


Further important features and advantages of the invention arise from the sub-claims and from the examples.

EXAMPLES
Example 1
Synthesis of 2-methyl-4-oxo-4H-pyran-3-yl 2-(4-dibutylamino-2-hydroxybenzoyl)benzoate



embedded image


15.0 g of 2-(4-dibutylamino-2-hydroxybenzoyl)benzoic acid, 6.1 g of 3-hydroxy-2-methyl-4-pyranone and 0.35 g of 2-(dimethylamino)pyridine are initially introduced in 120 ml of dichloromethane under argon. A solution of 10.0 g of N,N′-dicyclohexylcarbodiimide (DCC) in 30 ml of dichloromethane is added dropwise to this solution, and the mixture is stirred at room temperature for 2 days. In order to eliminate excess DCCs, 4.4 g of oxalic acid dihydrate are then added, and the mixture is left to stir at room temperature for a further 2.5 h. The reaction solution is cooled in an ice-water bath for 30 min and subsequently filtered off. 100 ml of water are then added to the mother liquor, and the mixture is extracted. The organic phase is subsequently rinsed again with water, then with saturated NaCl solution, dried using Na2SO4, filtered and evaporated in a rotary evaporator.


Re-uptake in ethyl acetate and purification of the solution on silica gel gives 7.9 g of 2-methyl-4-oxo-4H-pyran-3-yl 2-(4-dibutylamino-2-hydroxybenzoyl)-benzoate.

FIG. 1 shows the UV spectrum (200 to 400 nm) of the compound 2-methyl-4-oxo-4H-pyran-3-yl 2-(4-dibutylamino-2-hydroxybenzoyl)benzoate.


Example 2
Synthesis of 2-methyl-4-oxo-4H-pyran-3-yl 2-(E)-3-(4-methoxyphenyl)acrylate



embedded image


2.4 g of 3-hydroxy-2-methyl-4-pyranone are dissolved in 50 ml of dichloromethane at room temperature under argon. 4.5 g of trans-4-methoxycinnamoyl chloride are subsequently introduced, and 3.17 ml of triethylamine are slowly added dropwise. The mixture is left to stir at room temperature for 4 h. For filtration, the reaction solution is cooled to 0° C. The mother liquor is extracted with 25 ml of 1N HCl at room temperature. The organic phase is subsequently rinsed again with water, dried using Na2SO4, filtered, and the solvent is distilled off. For further purification, the residue is suspended in 15 ml of i-propanol, warmed briefly and stored in the refrigerator at 8° C. overnight. Suction filtration, rinsing and drying gives 4.8 g of 2-methyl-4-oxo-4H-pyran-3-yl 2-(E)-3-(4-methoxyphenyl)acrylate.

Example 3
Synthesis of 2-methyl-4-oxo-4H-pyran-3-yl 3-(benzotriazol-2-yl-4-hydroxy)-benzoate



embedded image


2.5 g of 3-hydroxy-2-methyl-4-pyranone are reacted with 7.5 g of benzotriazol-2-yl-4-hydroxybenzoyl chloride analogously to Example 2, giving 2-methyl-4-oxo-4H-pyran-3-yl 3-(benzotriazol-2-yl-4-hydroxy)benzoate.


Example 4
Synthesis of 2-ethylhexyl (E)-3-[4-(2-methyl-4-oxo-4H-pyran-3-yloxy)-phenyl]acryate



embedded image


10 g (79 mmol) of 3-hydroxy-2-methyl-4-pyranonine are dissolved 100 ml of dimethylformamide in a 3-necked flask which has been flushed with argon, 22.8 g of triphenylphosphine are added, and 17.6 g of diisopropyl azodicarboxylate (87 mmol) are slowly added dropwise at 0° C. After 30 min, 2-ethylhexyl (E)-3-(4-hydroxyphenyl)acrylate (23 g, 83 mmol) dissolved in 45 ml of dimethylformamide is added dropwise. After 30 min at 0° C., the mixture is stirred at room temperature for a further 6 hours. The reaction solution is evaporated to dryness, suspended in 100 ml of ethyl acetate/hexane 1:2, filtered, and the product is precipitated out as white solid by addition of 100 ml of hexane.


Example 5

Synthesis of (R)-5-[(R)-2-(3-benzotriazol-2-yl-4-hydroxybenzyloxy)-1-hydroxyethyl]-3,4-dihydroxy-5H-furan-2-one




embedded image


10 g of 3-hydroxy-2-methyl-4-pyranone (79 mmol) are dissolved in 250 ml of THF (tetrahydrofuran), and 3.2 g of sodium hydroxide (79 mmol) are added at 0° C. After 30 min, 2-benzotriazol-2-yl-4-bromomethylphenol (28.8 g) dissolved in 100 ml of THF is added dropwise, the mixture is stirred at 0° C. for 60 min and at 70° C. for 7 hours. After cooling to room temperature, the reaction solution is evaporated in a rotary evaporator. Re-uptake in the solvent and purification of the solution on silica gel gives (R)-5-[(R)-2-(3-benzotriazol-2-yl-4-hydroxybenzyloxy)-1-hydroxyethyl]-3,4-dihydroxy-5H-furan-2-one.


Example 6
Synthesis of 1,2-dimethyl-4-oxo-1,4-dihydropyridin-3-yl 2-(E)-3-(4-methoxy-phenyl)acrylate



embedded image


6.00 ml of triethylamine are added dropwise after 5 min to a suspension of 5.00 g (35.9 mmol) of 3-hydroxy-1,2-dimethyl-1H-pyridin-4-one in 100 ml of dichloromethane and 8.50 g (43.2 mmol) of E-4-methoxycinnamoyl chloride. The reaction mixture clarifies, and the internal temperature rises by 5° C. The orange-red reaction mixture is stirred at RT for a further 3 h. 100 ml of water are then added, and the mixture is carefully acidified using 25% hydrochloric acid. A yellow flocculent precipitate precipitates out in the process. This is separated off and dried in vacuo. After addition of a further 100 ml of water, yellow solid is again precipitated out of the mother liquor and separated off. The combined solids are stirred with 25 ml of dichloromethane for 30 min, filtered off with suction, rinsed with a little cold dichloromethane and subsequently dried at 40° C. in vacuo, giving 4.4 g (41%) of product as pale-beige powder.



1H-NMR (400 MHz, DMSO-d6): δ=2.49 (s, 3H), 3.78 (s, 3H), 4.07 (s, 3H), 6.69 (d, 1H, 3J=16.3 Hz), 6.98 (d, 2H, 3J=9.0 Hz), 7.35 (d, 1H, 3J=7.3 Hz), 7.71 (d, 2H, 3J=9.0 Hz), 7.89 (d, 1H, 3J=16.3 Hz), 8.56 (d, 1H, 3J=7.3 Hz).


Example 7
Evidence of Binding
Determination of the Protein Affinity in the Lysine Model:

In each case, 10 mg of the substances according to Example 1 and Example 2 are weighed out into a 10 ml volumetric flask and dissolved in 5 ml of tetrahydrofuran (THF). The volumetric flask is then made up to the mark with a lysine solution in distilled water. The concentration of the lysine solution is 200 mg/I of water. The solution is stirred in the volumetric flask at 35° C. for 24 h. Samples are taken after 1 h and after 24 h. 5 μl of each of these samples are pipetted onto the start zone of an HPTLC silica gel 60 F245 plate (Merck Art. 1.05628) using a micropipette. For development of the HPTLC plate, the eluent consisting of THF/heptane in the ratio 75/25 containing 0.1 vol % of formic acid is used. After development, detection is carried out at 254 nm and 366 nm in a CAMAG ATS4, and the Rf values are determined.


Result: the substance of Example 1 has an Rf value of 0.55. After only 1 h in combination with lysine, the substance according to Example 1 has completely reacted with lysine in a Maillard reaction. The starting substance can no longer be detected. By contrast, Maillard products have formed which are detected in the start zone of the HPTLC plate. Analogous results are achieved for the substance of Example 2 (Rf 0.47), where starting substance 2 can still be detected after 1 h, but the reaction is complete after 24 h. The substance of Example 2 is then no longer detectable, while Maillard products are detected in the start zone of the HPTLC plate.


Example 8
Investigation in the Liquidskin Model

1 mmol of the substance according to Example 1 (2-methyl-4-oxo-4H-pyran-3-yl 2-(4-dibutylamino-2-hydroxybenzoyl)benzoate) is dissolved in 94 ml of ethylene glycol and 6 ml of water (potassium hydrogenphthalate-buffered, pH=4) with 1 mmol of DL-lysine and stirred at RT for 3 hrs. (=Liquidskin model). The L*-a*-b* values of this solution are subsequently measured using a UV/VIS spectrometer (Varian Cary-100) and compared with the starting values.
