Definitions
- the present invention relates to the use of peripheral benzodiazepine receptor (PBR) ligands, in particular peripheral benzodiazepine receptor antagonists, in compositions which are useful in the field of treatment or prevention of the signs of aging of the skin, mucous membranes and / or integuments.
- PBR peripheral benzodiazepine receptor
- the invention thus relates to the use of such ligands of PBR to fight against wrinkles and fine lines and / or loss of radiance of the skin.
- the human skin consists of two compartments namely a superficial compartment, the epidermis, and a deep compartment, the dermis.
- the natural human epidermis is composed mainly of three types of cells, which are the keratinocytes, a very large majority, melanocytes and Langerhans cells. Each of these cell types contributes, by its own functions, to the essential role played in the body by the skin, in particular the role of protecting the body from external aggressions called "barrier function".
- the epidermis is conventionally divided into a basal layer of keratinocytes constituting the germinal layer of the epidermis, a so-called spinous layer consisting of several layers of polyhedral cells arranged on the germinal layers, one to three so-called granular layers consisting of flattened cells containing distinct cytoplasmic inclusions, keratohyalin grains and finally the stratum corneum, consisting of a set of layers of end-stage keratinocytes called corneocytes.
- Comteocytes are anucleate cells consisting mainly of a fibrous material containing cytokeratins, surrounded by a horny envelope.
- the dermis provides the epidermis with a solid support. It is also its nurturing element. It consists mainly of fibroblasts and an extracellular matrix composed mainly of collagen, elastin and a substance called the fundamental substance, components synthesized by the fibroblast. There are also leucocytes, mast cells or tissue macrophages. It is also crossed by blood vessels and nerve fibers.
- the extracellular matrix of the dermis like that of all the connective tissues of the body, is composed of proteins belonging to several large families: collagens, matrix glycoproteins other than collagens (fibronectin, laminin), elastin and proteoglycans. There are also glycosaminoglycans in free form (ie not bound to a protein).
- Proteoglycans are complex macromolecules consisting of a branched central protein trunk, or protein lattice, to which are attached a large number of polysaccharide side chains called glycosaminoglycans (also referred to as GAG).
- the main GAGs are hyaluronic acid or hyaluronan (HA), heparan sulfate (HS), heparin (HP), chondroitin, chondroitin sulfate (CS), chondroitin 4-sulfate or chondroitin sulfate A (CSA). ), chondroitin 6-sulfate or chondroitin sulfate C (CSC), dermatan sulfate or chondroitin sulfate B (CSB) and keratan sulfate (KS) which differs from other glycosaminoglycans in the presence of galactose in place of uronic acid .
- the GAGs are linked by anchoring structures to the different polypeptide chains, called “core" proteins or carrier proteins, and thus form PGs molecules.
- GAGs may also exist in the extracellular matrix in free form, ie not bound to a matrix protein: this is particularly the case of hyaluronic acid.
- the GAGs are polymerized from these anchoring structures.
- PGs and GAGs are also altered. Indeed, during aging, fibroblasts and keratinocytes produce less and less PGs and GAGs and their synthesis is imperfect. This results in significant disorganization: the deposit of GAGs on the protein skeleton forming the PG is abnormal, which results in less avidity for the water of these PGs and therefore a decrease in hydration and tonicity fabrics. Restoring a normal production of PGs and GAGs by fibroblasts and keratinocytes helps, in part, to compensate for loss of skin hydration.
- cornea there is permanently in the epidermis a production of new keratinocytes to compensate for the continuous loss of epidermal cells in the stratum corneum.
- proliferation and epidermal differentiation may be physiologically disturbed, and a tendency towards imbalance between these two mechanisms leading to thinning of the living layers of the epidermis and thickening of the epidermis may be observed.
- Expression wrinkles are the result of mechanisms different from those generating wrinkles due to aging and can appear early, from the age of 30 years.
- Expression lines are characterized by the presence of furrows around the orifices of the nose (nasolabial folds), the mouth (para-buccal wrinkles and so-called bitterness wrinkles) and the eyes (wrinkles of the paw d 'oie), around which lie the skin muscles, as well as between the eyebrows (wrinkles of the glabella or the lion) and on the forehead.
- the facial skin muscles are under the control of the motor nerve afferents of the facial nerve and that, moreover, the interlobular septa of the hypoderm contain within them fibers which constitute striated muscle tissue (panniculus camosus). ).
- myofibroblasts a subpopulation of dermal fibroblasts, called myofibroblasts, has common contractile characteristics with the muscle tissue.
- the means commonly used to act on expression lines are, on the one hand, botulinum toxin which is in particular injected into the wrinkles of the glabella (see JD Carruters et al., J. Dermatol, Sur ⁇ , Oncol., 1992 , 18, pp. 17-21) and on the other hand degradable implants based on collagen, hyaluronic acid or polylactic acid.
- various compounds likely to provide a muscle relaxant effect when applied topically to the skin, thus allow to act by another way on expression lines .
- calcium channel-associated receptor antagonists FR-2 793 681
- manganese and its salts FR-2 809 005
- alverine FR-2 798 590
- the receptor agonists associated with the chlorine channels including glycine (EP-0 704 210) and certain extracts of Iris pallida (FR-2 746 641).
- the subject of the present invention is the cosmetic use of at least one peripheral benzodiazepine receptor antagonist in a composition containing a physiologically acceptable medium, as an agent for reducing or preventing the signs of aging of the skin.
- PBR antagonists according to the present invention can improve the appearance of the skin by promoting its hydration, by improving its cell renewal, by promoting the synthesis of the constituents of the extracellular matrix and by relaxing the tensions of the contractile structures.
- GABA-A receptor denotes a macromolecular complex which, in addition to the GABA site, comprises sites for the attachment of benzodiazepines, barbiturates, alcohol and certain steroids. It is a receptor associated with a channel, preferably permeable to chlorine ions (Cl " ) incidentally to bromine ions (Br " ). The opening of this channel after binding ligands described above resulting in the penetration of CI ions "and hyperpolarization.
- CBR is present exclusively in the central nervous system (CNS) and is localized on neurons.
- Benzodiazepines are also known to bind to peripheral receptors. These peripheral receptors are called benzodiazepine receptors
- PBR mitochondrial benzodiazepine receptors
- DBI Diazepam Binding Inhibitor
- an 11kDa polypeptide of 86 amino acids is described as an endogenous ligand for PBRs.
- DBI is so named because it is capable of inhibiting the binding of tritiated diazepam to brain membranes and the opening of GABA-activated chlorine channel A (Beurdeley-Thomas et al., "The peripheral benzodiazepine receptors: a Journal of Neuro-Oncology, 46: 45-56, 2000.
- Zisterer et al. "Peripheral-type benzodiazepine receptors", Gen. Pharmac., Vol.29, No. 3, pp. 305-314, 1997).
- a molecule capable of triggering, by its binding to specific receptors, a biological action similar to the activity of the endogenous ligand is by definition an agonist.
- a molecule whose nature of interaction with the same receptors is different and which is therefore incapable of triggering the action-effect sequence (thus devoid of intrinsic activity) is by definition an antagonist (Schorderet et al. , "Pharmacology", Frison-Roche and Slatkine Editions, 1992).
- DBI is therefore a PBR agonist whose biological action leads to the synthesis of cholesterol and lipid.
- FR 2 811897 also discloses the use of derivatives capable of binding to peripheral benzodiazepine receptors, for the preparation medicaments for the treatment of dysfunction of these receptors, in particular inflammatory diseases.
- US 5,976,559 relates to compositions containing a chlorine channel agonist, for combating wrinkles and fine lines.
- a peripheral benzodiazepine receptor antagonist is defined as any molecule of organic or mineral origin having an affinity for peripheral receptor binding sites for benzodiazepines, and (i) capable of decreasing the production of pregnenolone induced by a PBR agonist
- the measurement of the affinity for peripheral receptor binding sites for benzodiazepines can be carried out according to one of the binding studies described in WO00 / 44384, WO02 / 07727, FR2811990, WO00 / 44751, WO03 / 082874, WO03 / 068753 or WO03 / 030937.
- Measurement of the ability to decrease the PBR agonist-induced production of pregnenolone (MBR) can be performed according to the method described in WO03 / 068753 and WO03 / 030937.
- cutaneous signs of aging we mean all the changes in the external appearance of the skin due to aging whether it is chrono-biological and / or photo-induced, such as wrinkles and fine lines, withered skin, soft skin , skin thinned, lack of elasticity and / or tone of the skin, but also any internal changes in the skin that do not always result in a modified appearance.
- the subject of the invention is in particular the use of a peripheral benzodiazepine receptor antagonist in a composition containing a physiologically acceptable medium, for reducing and / or preventing and / or delaying the signs of chronological aging.
- a physiologically acceptable medium is according to the invention a cosmetically or pharmaceutically acceptable medium, compatible with the skin, the mucous membranes, the nails and / or the hair.
- compositions according to the invention can be applied to the nails, the hair and more particularly to the skin and the mucous membranes. It is preferably a cosmetically acceptable medium, that is to say which has a color, a smell and a pleasant touch and which do not generate unacceptable discomfort.
- compositions are preferably cosmetic compositions or products.
- cosmetic product is meant any substance or preparation intended to be placed in contact with the various superficial parts of the human body (epidermis, hair and hair system, nails, lips and external genital organs) or with the teeth and mucous membranes. exclusively or principally for the purpose of cleaning, perfuming, changing the appearance and / or correcting body odor and / or protecting or maintaining it in good condition (Cosmetic Directive 76/768 Amended).
- peripheral benzodiazepine receptor antagonists decrease the differentiation of keratinocytes. This effect is evaluated in particular by measuring the activity of transglutaminase K1 (TGK1). Indeed, the epidermis is constantly renewed. The numerous cells produced at the basal layer can either remain quiescent, be removed by apoptosis or engage in a differentiation process to reconstitute the suprabasal layers of the epidermis. The final stage of epidermal differentiation is the corneification of the last living cell layers.
- transglutaminase K1 which participates in the formation of molecular bridges between the different precursors synthesized at the level of the living layers (involucrine, loricrine, keratinolin). This enzymatic activity is therefore a reflection of a terminal differentiation of the epidermis.
- transglutaminase K1 or TGK1
- Such an activity is opposed to the differentiation of the epidermis; these compounds improve the radiance of the complexion by causing a thickening of the epidermis and a limitation of the thickness of the stratum corneum.
- Such effects are particularly advantageous for the skin of the face, and in particular to limit the loss of radiance from age.
- peripheral benzodiazepine receptor antagonists are useful for promoting synthesis of extracellular matrix constituents, particularly epidermal macromolecules.
- the extracellular matrix is a set of structural molecules deposited and organized by the cells. These molecules are in turn able to influence cellular behavior.
- matrix elements fibronectin, proteoglycans and glycosaminoglycans suggest their potential roles in different processes such as nutrition and hydration of the skin.
- epidermis influence of cellular behavior (migration, epidermal differentiation).
- the PBR antagonists according to the invention are useful for increasing the amount of total epidermal glycosaminoglycans; they act in particular by increasing their synthesis by keratinocytes.
- Peripheral benzodiazepine receptor antagonists will therefore be useful according to the invention for improving the hydration of the epidermis, improving the barrier function and promoting the maintenance of water in the superficial layers of the skin.
- Such activity will be advantageous in all cases where the skin is dry and / or dehydrated. It is known that the skin tends to dry up with age, so one of the applications will be the treatment of skin dehydration, whether it is related to age or other causes, especially if it is constitutive.
- peripheral benzodiazepine receptor antagonists are useful as agents for relaxing and / or relaxing skin and / or subcutaneous tissue. They are particularly adapted to fight against wrinkles and fine lines, in particular to prevent and / or reduce expression lines.
- the peripheral benzodiazepine receptor antagonists are thus active, in accordance with the present invention, both at the level of the dermis and the epidermis and make it possible to combat a series of chronological signs of aging.
- the peripheral benzodiazepine receptor antagonists are useful as agents for combating age-related thinning of skin, against soft and withered skin, and / or for fight against lack of tone or elasticity of the skin.

The medium is then removed and replaced with SFM medium without supplements containing the product PK11195 or the pharmacological reference. The incubation is continued for 72 hours at 37 ° C. Tritiated glucosamine (D- [6- 3 H] -glucosamine, Amersham TRK398 (1.3 Tbq / mmol, 35Ci / mmol) is added for the 24 hours at the end of the day.
- glycosaminoglycans are extracted from the culture medium and the deposited matrix, with a chaotropic buffer and then purified by ion exchange chromatography.
- the radioactivity incorporated into the highly cationic molecules is counted by liquid scintillation. The results are expressed as a percentage of variation of the GAG synthesis with respect to the control.
- PK11195 a peripheral benzodiazepine receptor antagonist
- the principle of this test was to study the relaxing effect of a peripheral benzodiazepine receptor antagonist on an equivalent dermis model consisting of a collagen matrix seeded with normal human fibroblasts. These conditions are intended to mimic in vitro the dermic contractile phenomena that occur during mimicry of the face. Under these conditions, the cells spontaneously express tensile forces that induce retraction of the collagen gel. This results in a decrease in the total area of the equivalent dermis over time. The measurement of this surface makes it possible to evaluate the relaxation effects of substances previously brought into contact with the equivalent dermis.
- the lattices are prepared in 24-well plates (TO), in a complete fibroblast medium (DMEM, 2mM L-glutamine, Penicillin / streptomycin 50UI / ml / 50 ⁇ g / ml, without serum) containing rat tail collagen (Institut J. Boy; 1.3mg / ml final) 10 6 cells / ml (normal human dermal fibroblasts used in the 9th pass).
- DMEM complete fibroblast medium
- DMEM 2mM L-glutamine
- rat tail collagen Institut J. Boy; 1.3mg / ml final
- 10 6 cells / ml normal human dermal fibroblasts used in the 9th pass.
- the suspension volume is 400 ⁇ l per well.
- the lattices After one hour at 37 ° C., (collagen freezing time), the lattices are detached from the support and 1 ml of culture medium, containing bradykinin (0.1 ⁇ M final) and the product PK11195 at the concentration of 10 "6. M, was added per culture well, the plates were incubated at 37 ° C. and 5% CO2 and the size of the lattices was measured after 5 hours. The analysis of the surface of the lattices was carried out at Lucia software help after image processing.
- bradykinin induces a rapid contraction of the lattice of collagen which allows to mimic the physiological conditions of tension of the normal dermis.
- the product PK11195, a peripheral benzodiazepine receptor antagonist significantly increases the surface of collagen lattices after 6 hours of culture in the presence of bradykinin. This means that the PK11195 is able to induce a relaxation of the lattice and therefore has a dermorelaxing effect on this lattice.
- Example 4 anti-aging composition
- This composition can be applied morning and evening on the entire face and neck
- This cream is applied every evening on the entire face and neck to fight wrinkles and fine lines and loss of radiance of the skin.
