Nouveaux dérivés de benzylidène-cyclanones, leur procédé de préparation, leur utilisation en tant qu'agents anti-oxydants et comme filtres solaires, compositions cosmétiques et pharmaceutiques les contenant.New benzylidene-cyclanone derivatives, their preparation process, their use as antioxidants and as sun filters, cosmetic and pharmaceutical compositions containing them.
La présente invention a pour objet de nouveaux dérivés de benzylidène-cyclanones, leur procédé de préparation et leurs utilisations en tant qu'agents anti-oxydants ainsi que dans des compositions cosmétiques à usage quotidien ou antisolaire et dans des compositions pharmaceutiques pour le traitement des inflammations et allergies cutanées ou de certaines formes de cancer.The present invention relates to new benzylidene-cyclanone derivatives, their preparation process and their uses as antioxidants as well as in cosmetic compositions for daily or sunscreen use and in pharmaceutical compositions for the treatment of inflammations. and skin allergies or certain forms of cancer.
Il est bien connu que la peau est sensible aux radiations solaires qui peuvent provoquer un banal coup de soleil ou érythème mais aussi des brûlures plus ou moins accentuées.It is well known that the skin is sensitive to solar radiation which can cause a common sunburn or erythema but also more or less accentuated burns.
Cependant les radiations solaires ont également d’autres effets néfastes tels qu’une perte d’élasticité de la peau et l'apparition de rides conduisant à un vieillissement prématuré. On peut même aussi observer parfois des dermatoses. Le cas extrême est la survenance chez certains sujets, de cancers cutanés.However, solar radiation also has other harmful effects such as a loss of elasticity of the skin and the appearance of wrinkles leading to premature aging. We can even sometimes observe dermatoses. The extreme case is the occurrence in certain subjects of skin cancers.
Il est également souhaitable d’assurer aux cheveux une bonne protection contre la dégradation photochimique afin d’éviter un changement de nuance, une décoloration ou une dégradation des propriétés mécaniques.It is also desirable to provide the hair with good protection against photochemical degradation in order to avoid a change in shade, discoloration or degradation of the mechanical properties.
On sait par ailleurs que les constituants entrant dans les préparations cosmétiques ne possèdent pas toujours une stabilité suffisante à la lumière et se dégradent sous l’action des radiations lumineuses.It is also known that the constituents used in cosmetic preparations do not always have sufficient light stability and degrade under the action of light radiation.
Il est bien connu que la partie la plus dangereuse du rayonnement solaire est constituée par les radiations ultraviolettes de longueurs d'onde inférieures à 400 nm. On sait aussi que, de par l'existence de la couche d'ozone de l'atmosphère terrestre qui absorbe une partie du rayonnement solaire, la limite inférieure du rayonnement ultraviolet atteignant la surface de la terre se situe aux environ de 280 nm.It is well known that the most dangerous part of solar radiation is constituted by ultraviolet radiation of wavelengths less than 400 nm. We also know that, due to the existence of the ozone layer in the Earth's atmosphere which absorbs part of the solar radiation, the lower limit of ultraviolet radiation reaching the earth's surface is around 280 nm.
Par conséquent, il paraît souhaitable de disposer de composés susceptibles d'absorber les radiations ultraviolettes dans une large bande de longueurs d'onde allant de 280 à 400 nm, c'est-à-dire aussi bien les rayons UV-B de longueurs d'onde comprises entre 280 et 320 nm jouant un rôle prépondérant dans la production de l’érythème solaire, que les rayons UV-A de longueurs d'onde comprises entre 320 et 400 nm provoquant le brunissement de la peau, mais aussi son vieillissement et favorisant le déclenchement de la réaction érythémateuse ou amplifiant cette réaction chez certains sujets ou pouvant même être à l'origine de réactions phototoxiques ou photoallergiques.Consequently, it seems desirable to have compounds capable of absorbing ultraviolet radiation in a wide band of wavelengths ranging from 280 to 400 nm, that is to say both UV-B rays of length d wave between 280 and 320 nm playing a preponderant role in the production of solar erythema, as UV-A rays of wavelengths between 320 and 400 nm causing the browning of the skin, but also its aging and favoring the initiation of the erythematous reaction or amplifying this reaction in certain subjects or possibly even being at the origin of phototoxic or photoallergic reactions.
Au cours de ses recherches, la demanderesse vient de découvrir les nouveaux dérivés de benzylidène-cyclanones ayant la formule suivante :During its research, the applicant has just discovered the new benzylidene-cyclanone derivatives having the following formula:
(I) dans laquelle : et R, identiques ou différents, représentent un reste alkyle linéaire ou ramifié en C^-Cg ou un reste alcoxy linéaire ou ramifié en Cj-Cg, R2 et R3* identiques ou différents, représentent un atome d'hydrogène ou un radical hydroxyle, étant entendu que l'un au moins des radicaux R£ et Rg représente un radical hydroxyle, R^, Rg, Rg et R^, identiques ou différents, représentent un reste alkyle linéaire ou ramifié en C^-C^g, un reste aralkyle tel que benzyle non substitué ou substitué par un reste alkyle en C^-C^ ou alcoxy en C^-C^, un reste aryle tel que phényle non substitué ou substitué par un reste alkyle en C^-C^; les substituants R^ et R5 et/ou les substituants Rg et R^ peuvent former, avec l'atome de carbone du cycle auquel ils sont rattachés, un cycle saturé contenant de 5 à 12 atomes de carbone non substitué ou substitué par un ou plusieurs restes alkyle linéaires ou ramifiés en Cj-Cg, X représente soit un radical dans lequel n = 1 ou 2, soit un radical !I^N-Rg dans lequel Rg représente un atome d'hydrogêne, un reste alkyle linéaire ou ramifié en C^-Cg, un reste aralkyle tel que benzyle non substitué ou substitué par un reste alkyle en C^-C^ ou alcoxy en C^-C^, un radical hydroxyle, un reste -O-R^ dans lequel R^ représente un reste alkyle linéaire ou ramifié en C^-Cg, ou bien X représente un atome d'oxygène ou un atome de soufre.(I) in which: and R, identical or different, represent a linear or branched alkyl radical in C ^ -Cg or a linear or branched alkoxy residue in Cj-Cg, R2 and R3 * identical or different, represent an atom of hydrogen or a hydroxyl radical, it being understood that at least one of the radicals R £ and Rg represents a hydroxyl radical, R ^, Rg, Rg and R ^, identical or different, represent a linear or branched alkyl radical in C ^ - C ^ g, an aralkyl radical such as benzyl unsubstituted or substituted by a C ^ -C ^ alkyl radical or C ^ -C ^ alkoxy, an aryl radical such as phenyl unsubstituted or substituted by a C ^ alkyl residue -C ^; the substituents R ^ and R5 and / or the substituents Rg and R ^ can form, with the carbon atom of the ring to which they are attached, a saturated ring containing from 5 to 12 carbon atoms unsubstituted or substituted by one or more linear or branched Cj-Cg alkyl radicals, X represents either a radical in which n = 1 or 2, or a! I ^ N-Rg radical in which Rg represents a hydrogen atom, a linear or branched C alkyl radical ^ -Cg, an aralkyl residue such as benzyl, unsubstituted or substituted by a C ^ -C ^ alkyl or C ^ -C ^ alkoxy residue, a hydroxyl radical, a -OR ^ residue in which R ^ represents an alkyl residue linear or branched in C ^ -Cg, or else X represents an oxygen atom or a sulfur atom.
Outre leurs bonnes propriétés filtrantes dans la gamme de longueurs d'onde allant de 280 à 380 nm, les composés ci-dessus présentent simultanément, de manière inattendue, d'excellentes propriétés anti-oxydantes vis-à-vis de la peroxydation des lipides polyinsaturés et également vis-à-vis des substances susceptibles de subir des réactions d'oxydation thermo- ou photoinduites (telles que des protéines, des polymères...).In addition to their good filtering properties in the wavelength range from 280 to 380 nm, the above compounds unexpectedly simultaneously exhibit excellent antioxidant properties with respect to the peroxidation of polyunsaturated lipids and also with respect to substances liable to undergo thermo- or photoinduced oxidation reactions (such as proteins, polymers, etc.).
Or, on sait que la peroxydation des lipides implique la formation de radicaux libres intermédiaires qui endommagent les membranes cellulaires se composant, entre autres, de phospholipides et sont responsables notamment des phénomènes de vieillissement de la peau (A.L TAPPEL dans "Federation Proceedings" Vol. 32, No 8, Août 1973).However, it is known that lipid peroxidation involves the formation of intermediate free radicals which damage cell membranes consisting, inter alia, of phospholipids and are responsible in particular for the aging phenomena of the skin (AL TAPPEL in "Federation Proceedings" Vol. 32, No 8, August 1973).
Il est extrêmement intéressant de disposer de composés présentant à la fois des propriétés filtrantes dans une large bande et des propriétés anti-oxydantes potentialisant l'effet filtre. De tels composés peuvent permettre par exemple de mieux lutter contre le vieillissement prématuré de la peau dû à la peroxydation des lipides cutanés.It is extremely advantageous to have compounds having both filtering properties in a broad band and antioxidant properties potentiating the filtering effect. Such compounds can make it possible, for example, to better fight against premature aging of the skin due to the peroxidation of skin lipids.
Ils peuvent aussi permettre d'assurer une meilleure conservation des compositions cosmétiques comportant une phase grasse en évitant le rancissement des lipides insaturés qui y sont contenus et qui peuvent être d'origine animale comme la lanoline, la cétine (blanc de baleine), la cire d'abeille, le perhydrosqualène, l'huile de tortue, ou végétale comme l'huile d'olive, l'huile de ricin, l'huile de maïs, l'huile d'amande douce, l'huile d'avocat, l'huile de karité, l'huile de tournesol, l’huile de soja, l'huile d'arachide, les huiles de coprah ou de palmiste hydrogénées, des acides gras essentiels comme la vitamine F et certaines huiles essentielles présentes dans les parfums comme l'huile de citron ou de lavande.They can also make it possible to ensure better preservation of cosmetic compositions comprising an oily phase by avoiding the rancidity of the unsaturated lipids which are contained therein and which can be of animal origin such as lanolin, ketine (whale white), wax bee, perhydrosqualene, turtle oil, or vegetable oil such as olive oil, castor oil, corn oil, sweet almond oil, avocado oil, shea oil, sunflower oil, soybean oil, peanut oil, hydrogenated coconut or palm kernel oils, essential fatty acids such as vitamin F and certain essential oils found in perfumes like lemon or lavender oil.
La demanderesse a également découvert de manière extrêmement surprenante que les composés de formule (I) ci—dessus pouvaient être utilisés pour le traitement des inflammations et allergies cutanées et également dans la prévention de certains cancers.The Applicant has also discovered, extremely surprisingly, that the compounds of formula (I) above can be used for the treatment of skin inflammations and allergies and also in the prevention of certain cancers.
Outre leurs bonnes propriétés filtrantes et anti-oxydantes, les composés selon l'invention présentent un excellent caractère lipo-soluble ainsi qu'une très bonne stabilité thermique et une excellente stabilité photochimique.In addition to their good filtering and antioxidant properties, the compounds according to the invention have an excellent liposoluble character as well as very good thermal stability and excellent photochemical stability.
Ces composés présentent également l'avantage, de ne pas être toxiques ou irritants et d'avoir une parfaite innocuité vis-à-vis de la peau.These compounds also have the advantage of not being toxic or irritating and of being perfectly harmless towards the skin.
Ils se répartissent uniformément dans des supports cosmétiques classiques aptes à former un film continu et notamment dans les supports gras et peuvent ainsi être appliqués sur la peau pour constituer un film protecteur efficace.They are distributed uniformly in conventional cosmetic supports capable of forming a continuous film and in particular in fatty supports and can thus be applied to the skin to constitute an effective protective film.
La présente invention a donc pour objet les composés de formule (I) ci-dessus.The present invention therefore relates to the compounds of formula (I) above.
Dans cette formule, R^ et R peuvent désigner par exemple un radical méthyle, éthyle, n-propyle, isopropyle, n-butyle, isobutyle, tertiobutyle ou 1,l,3,3-tétraméthylbutyle ou bien un reste mëthoxy, éthoxy, propoxy, butoxy, pentyloxy, hexyloxy, heptyloxy ou octyloxy.In this formula, R ^ and R may denote, for example, a methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, tert-butyl or 1,1,3,3-tetramethylbutyl radical or else a methoxy, ethoxy or propoxy residue. , butoxy, pentyloxy, hexyloxy, heptyloxy or octyloxy.
