Abstract

The invention relates to the use of preservatives for stabilizing the circadian physiology and to their use for modulating the Klf9 gene expression.

Description

 Cosmetic and dermatological preparations containing one or more substances which modulate the gene for the "crippled-like factor 9" (Klf9)

The invention encompasses cosmetic and dermatological preparations containing one or more substances which modulate the gene for the "crippled-like factor 9" (Klf9), in particular those preparations for use on the skin or hair of a human for the repair and regeneration of the human skin.

Practically all human functions change systematically during the day and night, similar to a sine wave with a maximum value and a minimum value: activity and metabolic phases oscillate (with or without daylight) in a (not quite exact) 24-hour rhythm. For this reason one speaks of the inner rhythm (clock) also as the circadian clock.

As sleep is embedded in this vibration, so is the time of recovery, an understanding of the mechanisms of biological programs is all the more important as our modern technological (electivated!) Lifestyle is increasingly capturing the natural time structures of day and night blurred.

We possess innumerable different "internal clocks" whose uppermost control center (the so-called suprachiasmatic nucleus) lies directly above the junction of the two optic nerves, two nerve cell groups lying on the right and left, the size of a rice grain.

The most important timer for the inner clock is the daylight. How much or how little light the internal clock needs to develop its effect is genetically determined and inherited in the form of various chronotypes:

Genetic early risers need much less light than the so-called night owls to wake up, they are fit and active early in the morning, but are also early on Evening weaker and tired. The older you get, the more you become an early riser.

Due to different periods of light, the organism reacts particularly sensitively to differences in light at dawn and dusk. In addition to the daylight but there are also their own timer (rhythm generator) such. regular mealtimes or regular getting up.

The inner clocks cause a variety of chemical and biological processes, which, taken together, fundamentally affect health, performance, experience, behavior and mood.

Chronobiologists have found different time qualities. For example, analgesics have a stronger effect in the evening than in the morning. In the evening, pain is also felt much stronger. At night, the body temperature drops, the circulation is highly unstable, the sense of balance disturbed. The digestive power is optimal between 13 and 14 o'clock, while the brain power is minimal. Alcohol is broken down properly in the evening. Growth and regulation of the hormonal balance takes place in the nocturnal deep sleep phases, as well as the strengthening of cognitive (previously learned) skills.

Sleep is also subject to this circadian rhythm: It is a highly active process, divided into quite different stages of sleep.

Circadian rhytmic is an important regulatory function that also needs skin cells for regeneration and revitalization for a fresher appearance.

The epidermis can be subdivided into cell fractions with a high cell division capacity or cell division rate (stem cells and so-called transiently amplifying keratinocytes) and non-proliferative, stratified cell fractions which form the majority of the epidermis.

To Figure 1: Regulation and function of Klf9.

(d) Keratinocytes were irradiated with the specified dose of UVB and harvested 3 hours and 24 hours after irradiation. Error bar: standard deviation. ( ^** ) significance level p <0.05.

Keratinocytes are derived from epidermal stem cells that are located in the area of the stratum basale or in the area of the outer root sheath of the hair follicles. They traverse several stages of development as they are pushed up by coming cells, until they form a layer of flattened, dead corneocytes in the stratum corneum.

The time between differentiation in the stratum basale and Abschidferung as corneocyte in the stratum disjunctum is about one month, but can be used in certain diseases, e.g. Psoriasis, be shortened.

During this differentiation, the keratinocyte constantly changes its shape and geometric orientation. In the stratum basale, the keratinocytes arise from epidermal stem cells and have a roughly cylindrical shape.

In the stratum spinosum, the remodeling of the cells begins with an increase in volume and a change in the cell axis in a more horizontal direction. Keratohyaline grains are formed and remodeling progresses rapidly. It comes to flattening of the cells, the loss of the nucleus, the shrinkage due to fluid loss and finally to keratinization. In the following stratum corneum (horny layer) one can no longer detect keratinocytes. Keratinocytes became corneocytes.

The stratum corneum forms a barrier that keeps foreign bodies and germs out and protects the body from dehydration. Keratinocytes are actively involved in the immune response, in inflammatory processes and in wound healing. They can produce a variety of cytokines, growth factors and even complement factors. In many chronic inflammatory skin diseases in particular TNF-alpha and IL-1, but also many other interleukins and chemokines are released.

Keratinocytes contribute to UV protection by absorbing melanosomes (melanin-containing vesicles) from melanocytes. The melanin is stored around the nucleus and protects it from UV-related damage.

Organisms are naturally exposed to a rotation of the Earth during the day-night cycle, which has led to an evolutionary adaptation of the physiology and behavior of almost all living things to this rhythm.

At the molecular level, evolutionarily highly conserved endogenous regulatory mechanisms have been formed, which enable the regulation of physiological processes in a circadian (-24 h) rhythm. In mammals, the suprachiasmatic nucleus (SCN) of the hypothalamus serves as the central clock of the circadian clock. For synchronization of physiological processes in peripheral organs, the SCN controls i.a. the cyclical release of certain hormones (e.g., cortisol, melatonin), temperature homeostasis and neuronal signals.

In addition to central control, almost all organs at the cellular level have an autonomous mechanism for generating circadian rhythms. At the molecular level, the circadian rhythm is formed by self-regulating feedback loops that allow cyclic expression of genes and corresponding proteins of the molecular clockwork. Peripheral oscillators are essential for the circadian control of tissue-specific cellular and physiological processes.

Here, the daytime-dependent regulation of physiology and metabolism is largely controlled by the circadian control of tissue-specific gene regulators (so-called transcription factors) or central enzymes. The control of circadian regulated genes has strong variations between different tissues, indicating specific functions of the circadian clock in individual organs. Recent studies are increasingly providing evidence for circadian control of cell division processes by clock-controlled cell cycle regulators. Demensprechend leads a systematic disorder of the circadian system to increased occurrence of diseases associated with the loss of proliferation control (eg, cancer).

Although the skin, as the ultimate barrier between the organism and the environment, is particularly exposed to daytime variations of the environment (e.g., temperature, UV radiation), surprisingly few studies have been performed to characterize the circadian system in the skin.

Studies on mouse models revealed rhythmic gene expression of clock genes in skin biopsies and recently the circadian regulation of DNA repair in murine epidermis has been described. In the human system, however, a molecular clock in epidermal skin cells has so far not been characterized. Interestingly, however, the time-dependent proliferation of epidermal keratinocytes has been known for some time, but the molecular regulatory mechanisms of this observation are not yet known.

There is also increased evidence of a circadian regulation of essential skin functions such as barrier formation, blood circulation and skin hydration, skin pH and skin temperature. However, the age dependence of this daytime specific variation of skin functions as well as underlying molecular mechanisms has not been elucidated yet.

The daily use of cosmetic products, which develop their regenerating effect with topical application, can therefore make a significant contribution to increasing the well-being of consumers.

It is therefore desirable to develop cosmetic products that adapt to the specific daily requirements of the skin, it is also desirable to provide concrete individual substances that achieve cosmetic effects by exploiting the biorhythm of the skin. It is also desirable that these substances can be used in cosmetic preparations.

Which genes in the skin are regulated depending on the time of day was not yet known. The work underlying the present invention led to the identification of circadianly regulated genes in the skin, their functional characterization, and in particular the active substance-side modulation of individual circadian-regulated genes for influencing cell growth in skin cells. Accordingly, the gene Krüppel-like factor 9 {Klf9) could be identified as circadian regulated and its growth-inhibiting function of Klf9 in epidermal keratinocytes detected.

On the drug side, it has been discovered that Klf9 can be modulated via the glucocorticoid pathway by the application of preservative.

The present invention therefore relates to the use of unsaturated preservatives for stabilizing the circadian physiology of skin functions.

Dusk is the fluid transition between day and night before the beginning of the day or after the end of the day, which is created by light scattering in the atmosphere. One differentiates between the dusk - the evening transition from the brightness of the day to the darkness of the night after sunset - and the dawn - the contrasting case of the morning transition from the darkness to the brightness before sunrise. Physically, twilight means the period in which scattered light from the sun, which is below the horizon, is visible.

It has been found that, for example, administered during the period of bourgeois twilight unsaturated preservatives lead to particularly relaxed-looking skin conditions. According to the invention, therefore, the use of unsaturated preservatives for daytime specific modulation of Klf9 gene expression, characterized in that an effective amount of one or more unsaturated preservatives in a cosmetic preparation during the evening civil twilight is applied to the skin.

The following conditions can be understood as skin functions: deficient, sensitive or hypoactive states of the skin or of skin appendages degenerative phenomena of the skin (eg skin slackening, age spots, telangiectasias and disappearance of the epidermal and dermal cell layers, the components of the connective tissue, the reed cones and capillaries of the skin) and / or the skin appendages,

 decreased fatty acid replenishment (e.g., after washing).

 Visible vascular dilations (telangiectasia, cuperosis);

 Slackness and formation of wrinkles;

local hyper-, hypo- and false pigmentation (eg age spots) and increased susceptibility to mechanical stress (eg cracking), environmental (smoking, smog, reactive oxygen species, free radicals) and especially light-induced negative changes of the skin and the appendages,

 Pre- and post-treatment for topical application of laser and Abschleifbehandlungen z. As the reduction of skin wrinkles and scars serve to counteract the resulting skin irritation and promote the regeneration processes in the injured skin.

To identify circadian regulated genes in human skin, 20 healthy donors were sampled every 4 hours for a period of 28 hours. The skin biopsies were mechanically separated into the epidermis (epidermis) and dermis (subcutis). Subsequently, genome-wide gene expression profiles of the corresponding skin samples were prepared. In addition to known genes of the circadian clockwork (Bmall and Perl) as a positive control, a day-specific regulation of Klf9 was also observed (Fig. 1 a-c).

Klf9 is described as a growth regulator in the epithelial tissue of the uterus (Pabona et al., 2009, Simmen et al., 2008; Simmen et al., 2007), but no growth-modulating effect of Klf9 has been reported to date for the skin.

It could be shown that Klf9 gene expression in non-proliferative active cells is increased by a factor of -30 (Figure 2a). To test whether Klf9 has a direct influence on cell growth, the Klf9 gene dose was artificially modulated in keratinocytes. Increasing the K / 9 level (overexpression) resulted in reduced cell growth (Figure 2b). In contrast, an artificial reduction of Klf9 levels increased increased cell growth (Fig. 2c). Thus, the cell growth of keratinocytes can be directly influenced by the modulation of Klf9.

Sun exposure of the skin is a manifestly daytime-dependent phenomenon, and UV radiation can lead to decreased keratinocyte growth. As // 9-levels in the skin have their maximum at noon (correlating with maximum sun exposure), the question arose between UV exposure and Klf9 gene expression.

It could be shown that Klf9 is dose-dependently induced by UVB radiation (Fig. 2d). This effect is short-lived, so that the Klf9 levels 24h after irradiation are at the base level again (Figure 2c).

UV-induced growth reduction can be counteracted by modulation of Klf9.

It could also be shown that Klf9 modulating substances should be used for specific purposes in terms of daytime, especially in the evening hours.

For example, the graph in Figure 2 indicates the altered skin lipid status at different times of the day. It can be seen that in the evening, the fatty acid content in the skin is higher.

For the drug-side modulation of Klf9, the cortisol signaling pathway was identified.

Comparable effects of KLF9 modulation show certain preservatives selected from the group of parabens, phenylhydroxyalkyl ethers, sorbic acid or its alkali metal salts, IPBC, benzethonium chloride, methylisothiazolinone, piroctone olamine and / or

Lauroylethylarginat.

Parabens are p-hydroxybenzoic acid esters, in particular the methyl, ethyl, propyl, iso-propyl, phenoxyethyl, benzyl, n-butyl ester, more preferably the methyl or propyl ester (CAS: 94-13-3).

Further, phenylhydroxyalkyl ethers, in particular those under the name phenoxyethanol (CAS No. 122-99-6) are suitable.

The following preservatives are furthermore preferred according to the invention: IPBC is (3-iodo-2-propynyl) -N-butylcarbamate, CAS no. 55406-53-6.

Sorbic acid and alkali sorbates, especially potassium sorbates (CAS No: 24634-61-5)

Benzethonium chloride, benzyl-dimethyl- (4- {2- [4- (1, 1, 3,3-tetramethylbutyl) -phenoxy] -ethoxy} -ethyl) -ammonium chloride (CAS No .: 121-54-0)

Grapefruit seed extracts may contain benzethonium chloride in concentrations of

7-11% included.

Piroctone olamine, 1-hydroxy-4-methyl-6- (2,4,4-trimethylpentyl) -2 (1H) -pyridone, also referred to as octopirox, (CAS No: 68890-66-4) is an antimicrobial that as

Preservatives used and z. B. is used in shampoos as anti-dandruff. Octopirox is well tolerated by the skin and physiologically indifferent. Octopirox has the structure

Methylisothiazolinone (2-methyl-2H-isothiazol-3-one (MIT)) is a class of compounds with high microbicidal activity, which is mainly used for the preservation of technical products and now less of cosmetic products.

It is further preferred if the substance selected from the group of parabens,

Pyroctone olamine, methylisothiazolinone in concentrations of 0.001 to 2 wt.%, Particularly preferably 0.01 to 1, 0 wt.% Is present. The above-mentioned preservatives are usually used as microbicidal raw materials for formula preservation.

Nevertheless, it has been astonishing that the use of parabens, sorbic acid and derivatives IPBC to stabilize the circadian physiology of the skin remedies the disadvantages of the prior art.

The term "stabilizing the circadian physiology of the skin" is understood to mean that the substances used according to the invention put the skin into a nocturnal state of recovery, as a result of which it is also possible to restore or at least to equalize the external appearance of the recovered skin.
