The mechanism of ageing is generally divided into two different parts. The first part is called intrinsic ageing caused by factors derived from within the body. The second part is classified as extrinsic ageing provoked by environmental factors. During the process of ageing several impairments can be observed, e.g. a decline in metabolic activity, a lower rate of cell division, a reduced DNA repair capacity, stiffening of vessel walls and an impaired peripheral blood circulation. All these aspects are closely linked to each other.
However, the ageing process advances gender specifically due to the different hormonal structure.
For skin ageing the following physiological changes can be observed, for example: in the epidermis the reduction of mitosis rate of basal cells results in a thinner epidermis; in addition, a high water loss due to diffusion, a reduced elasticity, a rougher external structure and wrinkle formation are generally observed.
The dermis is impaired by less fibroblasts with reduced activity; further, a reduced production of tropocollagen, hyaluronic acid and elastin are observed as well as loss of elasticity, reduced sebum production and reduced perspiration.
For the subcutis changes in the palisade structure of feminine skin can be observed. All actions in the epidermis, the dermis and subcutis are reflected in the appearance of the stratum corneum. The skin looks thinner, dry and rough like parchment. For these reasons, an anti-ageing product should ideally focus on all skin layers and their changes accordingly and should be used as early as possible.
One field of skin ageing relates to the so called destructive modifications. These modifications target intracellular and extracellular proteins resulting in the loss of their biological function. Examples for destructive modifications are AGE-modifications (Advanced Glycation Endproducts) and carbonylations. AGE-modifications are based on the reaction between sugars and amino acid residues leading to crosslinked proteins. This is known for extracellular proteins like collagen as well as intracellular proteins like vimentin. The crosslinking of collagen results in increased stiffening of the skin whereas the glycation of vimentin is accompanied by the loss of contractile capacity of fibroblasts.
One group of intrinsic factors consists of matrix metalloproteinases (MMPs). MMPs are enzymes which cleave structural proteins in biological tissue. One of these proteins is collagen, the major constituent of the extracellular matrix of the skin. Collagen builds fibres in the skin and is therefore important for skin structure and firmness. For example, MMP-1 cleaves collagen resulting in the degradation of collagen. An activation of the proteasome results therefore in less MMP-1 and less collagen degradation, see e.g. J. Biol. Chem, 284(44), 30076-30086.
In aged skin, the amount of MMPs is increased resulting in fragmented collagen and finally in wrinkle formation. A prominent example for extrinsic ageing is the induction of MMPs by UV light, also called photo-ageing. There are several strategies to prevent the fragmentation of collagen. MMP action and/or amount can be reduced by the application of respective inhibitors. Furthermore, the induction of the skin's own MMP inhibitors, TIMPs (tissue inhibitor of metalloproteinases), protects against collagen degradation. In concert with MMP inhibition, the stimulation of collagen synthesis provides a powerful tool for repair of damaged tissue. Finally, sun protection by UV filters is an effective strategy for protection against photo-ageing.
Another constituent of the extracellular matrix is hyaluronic acid which belongs to the family of glucosaminoglycans (GAGs, also: glycosaminoglycans). This substance is composed of repeated disaccharide units, namely D-glucuronic acid and D-N-acetylglucosamine, building a complex polymer of different sizes. GAGs are major constituents of the extracellular matrix and are known for their extremely high water binding capacity. Two types of GAGs are known, acidic GAGs like hyaluronic acid, which is mainly involved in the preservation of the tissue hydration, and neutral GAGs like Chondroitin sulphate, which are mainly involved in intracellular signaling, cell communication in the dermal-epidermal-junction (DEJ) and stabilization of DEJ.
The age-induced loss of hyaluronic acid is therefore accompanied by a tremendous loss of tissue volume leading to sagging skin. This process is enhanced by the age-dependent decline of other GAG's like dermatan sulphate. Hallmarks of aged skin are also found in the upper epidermis: aged skin is marked by weakened epidermal barrier permeability, leading to dry skin. The permeability barrier is located in the horny layer and consists of lipid bilayers surrounding the corneocytes.
Ceramides, cholesterol and fatty acids are the main lipid constituents of the epidermal barrier significantly reduced in aged skin. Therefore, topical application of (pseudo-)ceramides, combined with free fatty acids and cholesterol helps to prevent and to repair dry skin.
Another reason for the dryness of aged skin is the reduced amount of the skin's own moisturizers (natural moisturizing factor, NMF).
A significant trigger for ageing is the development of reactive oxygen species (ROS). Two major sources are known for the formation of ROS. The first source is the extrinsic ageing factor UV-light which induces ROS formation like hydroxyl radicals, superoxides, peroxides and other reactive species which can virtually damage all kinds of macromolecules. Reactive oxygen damage the proteasome resulting in an impaired activity, see for example J. Biol. Chem, 284(44), 30076-30086.
The second intrinsic source for free radicals is the mitochondrial electron transport chain. The mitochondrium is the cellular power station generating ATP, which is the driving force for nearly every biological function in the cellular metabolism. Although the mitochondrial electron transport chain works with a high efficacy, the machinery is not perfect and misdirected electrons result in the production of toxic free radical superoxides and therewith in oxidative stress. The most potent cellular defense mechanism to scavenge free radicals is the glutathione system combined with enzymes that dissipate free radicals, namely catalase and superoxide dismutase. Even small doses of UV or other stress factors override these protective systems. This is the point where topical antioxidant application becomes important to prevent oxidative damage.
Another strategy to reduce the mitochondria-based oxidative stress is the theory of calorie restriction. There, reducing the input of calories may result in a lower activity of the metabolism and a decreased ROS production. A common diet-restriction regimen used in experimental animals is a 30% reduction in food intake resulting in a significantly prolonged healthy lifespan.
A class of enzymes called sirtuins (sirtuin proteins) was shown to be upregulated in mammals when set under calorie restriction and is thought to be an important player promoting longevity. In consequence, stimulation of sirtuins (SIRTs), namely of SIRT1, has recently become an important target for anti-ageing actives.
The sirtuins post-translationally modulate the function of many cellular proteins that undergo reversible acetylation-deacetylation cycles. These modifications affect physiological responses that have implications for ageing in humans. In mammals there are seven members of the sirtuin family, SIRT 1-7, of which SIRT1 is the best studied protein. The protein SIRT1 is an NAD+-dependent deacetylase catalyzing the reaction in which an acetyl group is removed from lysine side chains of proteins or peptides cleaving NAD+, which acts as a co-substrate. This results in the deacetylated protein 2″-O-acetyl-ADP-ribose and nicotinamide.
The polyphenol Resveratrol was shown to increase the deacetylase activity of certain sirtuin proteins thereby extending lifespan of yeast by 70% and fish by 60%.
Some examples for the SIRT1 deacetylation substrates include PGC1α, FOXO, p53, and the p65 subunit of the nuclear factor-κB. These targets belong to the central regulators of the cellular metabolism, energy expenditure, inflammation and stress response. Overexpression of SIRT1 results therefore in the stimulation of mitochondrial biogenesis and metabolic rate as well as the modulation of insulin sensitivity.
Furthermore, in white adipose tissue, an increase in SIRT1 protein level or enzyme activity decreases adipogenesis and lipid stores. The anti-inflammatory effect of SIRT is based on the suppression of NF-κB activity or through cyclooxygenase 2 inhibition. Excessive activation of NF-κB was reported to be present in aged skin, linking inflammation to ageing. One result of NF-κB activation is the expression of destructive matrix metalloproteinases leading to fragmented collagen observed in skin of elderly people. An additional key factor for the anti-ageing properties of SIRT1 is the activation of the heat shock response. The heat shock factors (i.e. HSP70) are essential for protecting cells from protein-damaging stress associated with misfolded proteins. This chaperone activity regulates protein homeostasis. Recent studies were also able to link SIRT1 to ageing diseases of the heart as well while overexpression of SIRT 1 showed an attenuation of cardiac hypertrophy, apoptosis, fibrosis, cardiac dysfunction and expression of senescence marker. Furthermore it indirectly supports cardiac function by deacetylating the eNOS enzyme. SIRT1 was shown to increase upon calorie restriction in rodent and human tissue like white adipose, liver, skeletal muscle, brain and kidney. Additionally, small molecule activators of SIRT1 replicate signalling pathways triggered by calorie restriction in vivo. Cosmetic activators of SIRT1 provide therefore benefits as anti-ageing ingredient while acting as cell life prolongators and energy stimulators. Activators of SIRT1 will therefore be beneficial as anti-wrinkle agents and cellular protectors in general. Furthermore these activators prevent inflammation induced ageing (inflammageing) by reducing proinflammatory cytokines leading to an even skin tone and reduced pigment spots.
One of the most disturbing signs of ageing is the loss of even skin tone due to an irregular distribution of collagen, haemoglobin and the formation of age spots. The underlying mechanism of the development of age spots is still unclear, however the current opinion is that the dark spots are composed of accumulated melanin and lipofuscin. In addition, age spots appear as invaginations of the basal membrane and a striking increase in the number of dermal papillae combined with irregular arranged melanin clusters was observed. Furthermore, the formation of age spots goes along with the upregulation of genes described for inflammatory response. The oldest approach to lighten age spots is the topical application of substances that bleach melanin. An alternative strategy for the lightening of age spots is the inhibition of the enzyme tyrosinase which is essential for the synthesis of new melanin. Additionally, the prevention of melanocyte proliferation can be a useful strategy to reduce the amount of melanin produced.
The proteasome degrades damaged, misfolded, oxidized or unnecessary proteins. Seeing that, the proteasome is among other things involved in life span regulation of proteins, cell cycle control, gene expression, (oxidative) stress, immune response and carcinogenesis. Specifically, the proteasome is responsible for cell clearance of abnormal, denatured or in general damaged proteins as well as for the regulated degradation of short-lived proteins. Efficient protein degradation is one of the major factors that contribute to the retention of cellular homeostatic balance.
The 20S proteasome is a cylindric structure, with a molecular weight of 700 kDa, an approximately diameter of 12 nm and a length of 17 nm, which consists of 4 rings. The two outer rings are made of 7 different α-subunits. The other 2 rings build the middle structure of the 20S proteasome and consist of 7 diverse β-subunits. The outer α-rings control the access of 20S-proteasome substrates into the inner proteolytic chamber, which is made up by the two β-rings. This proteolytic activity could be divided into three different parts: 1. Peptidyl-glutamyl-peptide-hydrolysing activity (caspase like activity); 2. Trypsin like activity and 3. Chymotrypsin like activity.
Products of the proteasomal degradation are oligopeptides, generally with a length of 8-10 amino acids. In contrast to the 26S proteasome there is no need for polyubiquitination to degrade proteins by the 20S proteasome. Furthermore, degradation by the 20S proteasome is ATP-independent.
In response to the skin the proteasome has an important role in ageing/photo-ageing. The meaning of photo-ageing is skin ageing after (long term) chronic exposure to UVA and UVB light. Following UV energy absorption there are different changes in the skin, including production of free radicals, modified proteins and 4-hydroxy-2-nonenal (HNE). These products affect the gene expression in skin cells and lead to an increase of matrix metalloproteinases (MMPs) and a decrease of their inhibitors (TIMPs) which results in a reduction of collagen and therefore in wrinkle formation. A drastic decline in proteasome activity and a simultaneous accumulation of modified and ubiquitinated proteins after UV irradiation in human keratinocytes has been reported. Today it is proven that there is a decline of proteasome activity and expression in human keratinocytes and fibroblasts during ageing. It is evident that this down regulation of proteasome activity is a result of protein aggregation. In a circuit, shrinking of proteasome activity leads to new protein aggregates and non degraded polyubiquitinated proteins, which in turn affect the proteasome again. Based on these findings, skin ageing is linked to proteasome dysfunction and preservation of “normal” proteasome function allays skin ageing.
SDS and some fatty acids have been reported to stimulate proteasome activities in the test tube by favoring the open confirmation of the proteasome. Recently, isolated oleuropein, the most abundant of the phenolic compounds in Olea europaea leaf extract, olive oil and olives was shown to have stimulatory impact on proteasome activities. Furthermore, a phaeodactylum algae extract was reported to stimulate proteasome activity (WO 02/080876) as well as Palmitoyl Isoleucin.
Besides the stimulation of proteasome activity by stimulation of one or more of the enzymatic activities, the upregulation of the proteasomal proteins itself is a potent method to induce the proteasomal degradation. This is of special interest regarding the fact that not only proteasomal activity declines in elderly people but also the expression of proteasomal subunits. Overexpression of proteasomal subunits in primary human embryonic fibroblasts and the accompanied increased rate of lipolysis were shown to extend the lifespan of these cells by 15-20%.
Moreover, it was shown that restoration of the normal level of proteasome subunits in aged human fibroblasts reduces the level of ageing biomarkers. A decline of proteasome activities has been revealed in human primary cultures undergoing replicative senescence, whereas proteasome inhibition in young cells induces premature senescence.
Maintenance of cellular homeostasis influences the rate of ageing and is determined by several factors, including efficient proteolysis of damaged proteins. Protein degradation is predominantly catalyzed by the proteasome. Specifically, the proteasome is responsible for cell clearance of abnormal, denatured or in general damaged proteins as well as for the regulated degradation of short-lived proteins. As the proteasome has an impaired function during ageing, actives that restore its function are needed. Furthermore, UV irradiation impairs proteasomal function, thereby enhancing the cellular deposition of toxic proteins. Importantly, centenarians show a very high activity of the proteasome and are a good example of healthy ageing.
The activation of the proteasome is also linked to age-associated diseases, especially the neurodegenerative diseases in which misfolded proteins aggregate. Proteasome activators enhance the survival of Huntington's disease neuronal model cells and the development of Alzheimer's disease and Parkinson's disease is partly based on an inefficient proteasomal clearance.
Skin-lightening active ingredients intervene in one form or another in melanin metabolism or catabolism. Melanin pigments, which are normally brown to black in colour, are formed in the melanocytes of the skin, transferred to the keratinocytes and give the skin or hair its colour. In mammals, the brown-black eumelanins are primarily formed from hydroxy-substituted aromatic amino acids such as L-tyrosine and L-DOPA, the yellow to red pheomelanins additionally from sulfur-containing molecules (Cosmetics & Toiletries 1996, 111 (5), 43-51).
Skin-lightening agents are used for various reasons: if for some reason the melanin-forming melanocytes in human skin are not evenly distributed, pigment spots occur which are either lighter or darker than the surrounding skin area. To overcome this problem, skin lightening agents are sold which at least partially help to balance out such pigment spots. In addition, many people have a need to lighten their naturally dark skin colour or to prevent skin pigmentation. This requires very safe and effective skin and hair lightening agents.
One area of application in this regard is the therapeutic treatment of melanin-induced pigmentation disorders such as hyperpigmentations (e.g. scar hyperpigmentations, post-traumatic drug-induced hyperpigmentations, post-inflammatory hyperpigmentations induced by phototoxic reactions, ephelides).
Furthermore, UV-absorbing substances are also used to protect against the increase in skin pigmentation caused by UV light. UV absorbers do not bring about a true lightening of the skin but merely inhibit the increase in skin pigmentation caused by UV light.
U.S. Pat. No. 4,959,393 discloses 4-alkyl-resorcinols as skin lightening agents. WO 2004/105736 teaches certain diphenylmethane-derivatives as skin lightening agents.
Hydroquinone, hydroquinone derivatives such as e.g. arbutin, vitamin C, derivatives of ascorbic acid such as e.g. ascorbyl palmitate, kojic acid and derivatives of kojic acid such as e.g. kojic acid dipalmitate, are used in particular in commercial cosmetic or therapeutic skin lightening preparations.
The object of the present invention was to provide effective agents which enable prolongation of the life span of a cell, preferably of a human skin cell and/or a human neuronal cell, by inhibition of cellular senescence. Preferably, said agents should achieve said effect either via proteasomal clearance in a cell or via stimulation of proteasome activity and/or proteasome expression activation (Route (A)) or via stimulation of activity and/or expression of one or more sirtuin proteins (sirtuins) (Route (B)), in particular of SIRT1. More preferably, the agents should exhibit activity along both pathways, i.e. achieve the desired effect by exhibiting activity in Route (A) and in Route (B).
It has surprisingly been found that this object can be achieved by using compounds of formula (I) or a cosmetically acceptable salt of a compound of formula (I) or a mixture containing two or more of these compounds or the salts thereof
wherein
A denotes
wherein X, Y and Z independently of one another denote hydrogen, C1-C4-alkyl or C2-C4-alkenyl,
wherein optionally two of the radicals X, Y and Z are covalently bonded to one another under formation of a bicyclic ring system, in such a bicyclic ring system two of the radicals X, Y and Z together preferably form a radical having 1 to 4 carbon atoms, preferably a hydrocarbon radical having 1 to 3 carbon atoms,
B denotes NR1R2, wherein
R1 denotes hydrogen or an organic radical having 1 to 14 carbon atoms,
R2 denotes an organic radical having 1 to 14 carbon atoms,
and
wherein optionally R1 and R2 are covalently bonded to one another, preferably so that B is a 3 to 8 membered ring.

wherein R1, R2 and X, Y and Z have the meaning indicated hereinbefore or hereinafter.
As common in the art, in the context of the present invention, the substituents X, Y, and Z can in each case occupy—as indicated in the different structural formulae—any position in the cyclohexyl ring, i.e. in ipso, ortho, meta or para position to the cyclohexyl-carbon atom bonded to the oxygen of group A.
It is thus evident that two of the substituents X, Y, and Z—with exception of the ipso-position—can be bonded to the same carbon atom of the cyclohexyl ring of group A.
Surprisingly, it was found that the compounds of formula (I) not only stimulate SIRT1 expression, but also lead to an increase of proteasome activity and/or proteasome expression, thereby leading to proteasomal clearance in a cell. Thus it was found that compounds of formula (I), in particular the preferred and the particularly preferred compounds of formula (I) mentioned hereinbelow, exhibit activity along both pathways mentioned above, i.e. achieve the desired effects by exhibiting activity in Route (A) and/or in Route (B).
No mention or suggestion is made in the prior art of a cosmetic or therapeutic use of compounds of formula (I) as anti-ageing agents or of compounds of formula (I) having anti-ageing action.

The compounds of formula (I) can be used in the context of the present invention in the form of the pure stereoisomeric form or in the form of any mixture of stereoisomers. The compounds of formula (I) can also be used in the context of the present invention in the form of the pure enantiomers or in the form of any mixture of enantiomers, in the latter case racemates being preferred.

For the sake of clarity, carbamates of “flat” structural formula (I) thus include all stereoisomeric forms thereof.

The menthyl carbamates of formula (M-X) are derived from 2-isopropyl-5-methylcyclohexanol (p-menthan-3-ol) which has three asymmetric carbon atoms in its cyclohexane ring and occurs as four pairs of enantiomers.
These isomers can be illustrated by the following formulae, showing one enantiomer each of the four diastereomers.
The enantiomers (IIa) to (IId) and their optical antipodes may, for example, be obtained by hydrogenation of thymol (e.g. WO 2004/018398 and the references cited therein) or via cyclization of citronellal to the corresponding isopulegol-isomers and subsequent hydrogenation. The menthol isomers can be separated via accurate distillation (for more details on manufacturing and separation of menthol isomers see “Common Fragrance and Flavor Materials”, 4th Edition, Wiley-VCH, Weinheim 2001, 52-55).
Structurally derived from the enantiomers (IIa) to (IId) and their optical antipodes are the following compounds of formula (I).

These skin lighteners are preferred due to their very good activity, in particular in combination with one or more of the preferred or particularly preferred compounds of formula (I) according to the present invention.
Preparations according to the present invention including (a) one or more compounds of formula (I) and (b) one or more tyrosinase inhibitors have shown to exhibit particularly improved, in particular faster and/or stronger, activity, based on the modulation of two independent cellular mechanisms.
Preferred skin lightening actives to be combined with one or more compounds of formula (I) are tyrosinase inhibitors and are preferably selected from the group consisting of kojic acid and skin lightening resorcinol derivatives, preferably 4-alkylresorcinols, in particular 4-C3-C8-alkylresorcinols, and 4-(1-phenylethyl)1,3-dihydroxybenzene.

The melanin production is often stimulated as a result of an inflammation, a process called postinflammatory hyperpigmentation. Skin insults that result in inflammation/irritation can induce postinflammatory hyperpigmentation. Among such insults are acne lesions, ingrown hairs, scratches, insect bites, and surfactant damage. One of the most common forms of postinflammatory hyperpigmentations is tanning following exposure to sunlight as a response to UV damage to skin. Although in the latter, there may not be visible erythema, histologically, such exposed skin has elevated inflammatory/irritant cell content, yielding a “subclinical” inflammatory/irritant process. Thus to prevent inflammation/irritation of the skin is beneficial regarding the inhibition of melanogenesis in the skin.
One further area of application of compounds of formula (I) and of preparations according to the present invention is the therapeutic treatment of melanin-induced pigmentation disorders such as hyperpigmentations (e.g. scar hyperpigmentations, post-traumatic drug-induced hyperpigmentations, post-inflammatory hyperpigmentations induced by phototoxic reactions, ephelides).
Reactive oxygen species, such as superoxide and nitric oxide, generated in damaged skin (e.g. resulting from UV exposure) or released as by-products from inflammatory cells are known stimulators of melanogenesis in melanocytes. In such a case it is important to maintain the cellular redox by the suppression of reactive oxygen species, and to boost anti-oxidative defenses for the prevention of melanogenesis.
Thus, preferred preparations, preferably cosmetic preparations, according to the invention containing one or more compounds of formula (I) preferably additionally contain
The total amount of anti-irritants (one or more compounds) and anti-inflammatory substances (one or more compounds) in the preparations according to the invention is preferably 0.01 to 20 wt. %, particularly preferably 0.03 to 10 wt. %, in particular 0.05 to 5 wt. %, based on the total weight of the preparation.
Steroidal anti-inflammatory substances of the corticosteroid type, such as e.g. hydrocortisone, dexamethasone, dexamethasone phosphate, methyl prednisolone or cortisone, are advantageously used as anti-inflammatory active ingredients or active ingredients to relieve reddening and itching, the list of which can be extended by the addition of other steroidal anti-inflammatories. Non-steroidal anti-inflammatories can also be used. Examples which can be cited here are oxicams such as piroxicam or tenoxicam; salicylates such as aspirin, disalcid, solprin or fendosal; acetic acid derivatives such as diclofenac, fenclofenac, indomethacin, sulindac, tolmetin or clindanac; fenamates such as mefenamic, meclofenamic, flufenamic or nifiumic; propionic acid derivatives such as ibuprofen, naproxen, benoxaprofen or pyrazoles such as phenylbutazone, oxyphenylbutazone, febrazone or azapropazone. Anthranilic acid derivatives, in particular avenanthramides described in WO 2004/047833, are preferred anti-itch ingredients in a composition according to the present invention. Alternatively, natural anti-inflammatory substances or substances to relieve reddening and itching can be used.

Cosmetic or pharmaceutical preparations containing one or more compounds of formula (I) may, in particular if crystalline or microcrystalline solid bodies such as, for example, inorganic micropigments are to be incorporated in the preparations, according to the invention also contain anionic, cationic, non-ionic and/or amphoteric surfactants mentioned in WO 2005/123101.
Anionic surfactants generally have carboxylate, sulfate or sulfonate groups as functional groups. In aqueous solution they form negatively charged organic ions in the acid or neutral environment. Cationic surfactants are almost exclusively characterised by the presence of a quaternary ammonium group. In aqueous solution they form positively charged organic ions in the acid or neutral environment. Amphoteric surfactants contain both anionic and cationic groups and therefore behave in aqueous solution in the same way as anionic or cationic surfactants, depending on the pH. They have a positive charge in a strongly acid environment and a negative charge in an alkaline environment. In the neutral pH range, by contrast, they are zwitterionic. Polyether chains are typical of non-ionic surfactants. Non-ionic surfactants do not form ions in the aqueous medium.
Anionic surfactants which can advantageously be used are acyl amino acids (and salts thereof), such as
Cationic surfactants which can advantageously be used are
Quaternary surfactants contain at least one N atom, which is covalently bonded to 4 alkyl or aryl groups. This leads to a positive charge, regardless of the pH. Alkyl betaine, alkyl amidopropyl betaine and alkyl amidopropyl hydroxysulfaine are advantageous. The cationic surfactants used can also preferably be chosen from the group of quaternary ammonium compounds, in particular benzyl trialkyl ammonium chlorides or bromides, such as benzyl dimethylstearyl ammonium chloride for example, also alkyl trialkyl ammonium salts, for example cetyl trimethyl ammonium chloride or bromide, alkyl dimethyl hydroxyethyl ammonium chlorides or bromides, dialkyl dimethyl ammonium chlorides or bromides, alkyl amide ethyl trimethyl ammonium ether sulfates, alkyl pyridinium salts, for example lauryl or cetyl pyrimidinium chloride, imidazoline derivatives and compounds having a cationic character such as amine oxides, for example alkyl dimethyl amine oxides or alkyl aminoethyl dimethyl amine oxides. Cetyl trimethyl ammonium salts are particularly advantageously used.

75.6 g (0.56 mol) of para-tolylisocyanate were placed with 500 ml toluene in a one litre vessel and subsequently 73.4 g (0.51 mol) of 2-isopropylcyclohexanol were added. The reaction mixture was heated to reflux for 6 hours. After cooling to room temperature 50 g of water were added and the mixture was refluxed for one more hour. After phase separation the solvent was stripped off and the crude product recrystallized from 235 g of n-heptane. The product (79.8 g) was obtained in form of off-white crystals in 99.2% purity. This corresponds to a theoretical yield of 56%.

30 mmol of l-menthol were placed with 110 ml dichlormethane in a 250 ml vessel at room temperature and 3.08 g (39 mmol) of pyridine were added. The reaction mixture was cooled to 0° C. and 3.56 g (12 mmol) of triphosgene in 15 ml dichlormethane were added dropwise. After five minutes 2.37 g (30 mmol) pyridine were added. Subsequently, 2.19 g (30 mmol) of diethylamine in 15 ml dichlormethane were added dropwise, the resulting mixture was allowed to come to ambient temperature and then quenched with water. After separation of the phases, the water phase was extracted once with dichlormethane and the combined organic phases were concentrated. The raw product was purified by distillation and column chromatography to yield 1.5 g of the desired product as a mixture of isomers with a purity of 99.4%.

NHDF cells (normal human dermal fibroblasts) were seeded in 96-well plates. After 24 h cultivation at 37° C. and 5% CO2 in DMEM (Dulbecco's Modified Eagle Medium), cells were treated with test substances for another 48 h. After washing the cells with PBS (phosphate buffered saline), the cells were fixed with paraformaldehyde and permeabilized. Then they were washed again and blocked with BSA (bovine serum albumen), followed by incubation with secondary antibody. After extensive washing, the fluorescence is measured in a microplate reader and fluorescence images were recorded on a fluorescence microscope with an attached closed-circuit display camera.
The stimulation of SIRT1 expression was calculated by:
RFU test substance=relative fluorescent units of the wells with test substance, stained completely
RFU control=relative fluorescent units of the wells without test substance, stained completely
RFU background=relative fluorescent units of the wells without test substance, stained only with secondary antibody.
Examples 3.1 and 3.2 describe the measurement of proteasome activity of BIO1272.
The method used herein to investigate the proteasome stimulating activity of a substance is based on the measurement of the 20S proteasome core activity. To detect this activity, the isolated 20S proteasome reacts with an oligopeptide, which is bound to a fluorochrome. With its chymotrypsin-like proteolytic activity, the proteasome degrades the oligopeptide and liberates the fluorochrome. For this assay 4-methyl-coumaryl-amide (MCA) was used as fluorochrome. Liberation of MCA correlates linearly with the proteasome activity. MCA was detected using an excitation of 360 nm and an emission of 460 nm.
For interpretation, the measured proteasome activities/intensities of fluorescence were compared with pure MCA standards at distinct concentrations.
Two different controls were used for each assay. One “ordinary” control (C) which consisted of isolated proteasome alone, and a DMSO-control (DC). DC was necessary because all substances were diluted in DMSO. Proteasome activity was calculated relative to DMSO control (0 mM).
To determine proteasome activity in cell lysate, human keratinocyte cell lines (HaCaT cells) were seeded out in Petri-dishes (area: 22.1 cm2) and harvested when they reached confluence. Isolation of the pure cell lysate included cell washing, incubation and homogenization in lysis buffer (250 mM sucrose, 25 mM HEPES (4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid), 10 mM MgCl2*6H2O, 1.3 mM EDTA) and final cell lysis with liquid nitrogen. Determination of proteasome activity is based on the liberation of MCA and the corresponding fluorescence like described above in example 3.1. Proteasome activity was calculated relative to DMSO control (0 mM).
