摘要:
The present invention relates to drugs consisting of unsaturated fatty amino-acid derivatives of the general formula (I), and to their pharmaceutically acceptable acid addition salts, in which: X is oxygen or NH, Rn are independently hydrogen or a (C1-C6)alkyl optionally substituted by halogen; R1 is hydrogen, fluorine, chlorine or bromine, or a CF3 or CHF2 or a (C1-C6)alkyl, (C1-C6)alkenyl or (C1-C6)alkynyl, optionally substituted by one or more halogen atoms; R is hydrogen or a (C1-C6)alkyl or (C3-C6)cycloalkyl optionally substituted by one or more halogen atoms; Ra and Rb are independently hydrogen (C1-C6)alkyl or (C1-C6)acyl, and Ra and Rb a hydrocarbonated cycle containing 4 to 6 carbon atoms; and n is an integer between 2 and 14.
摘要:
The invention concerns the cosmetic or dermatological use of at least one compound of formula (I), wherein: R1, R2, R3, R4, R5 and G are such as defined in the description as whitening and/or depigmenting agents for the skin and/or hairs and/or the hair. The invention also concerns a cosmetic method for whitening and/or lightening the skin and/or hairs and/or the hair comprising applying a composition of the invention.

摘要:
The present invention relates to the activation of peptidyl arginine deiminase (PADs) 1 and/or 3 in the epidermis by at least one active agent used alone or in combination, namely caffeine, acefylline and/or theobromine in a cosmetic and/or pharmaceutical composition. The present invention also relates to the use of the aforementioned active agents in cosmetics and/or therapeutics, alone or in combination, in order to improve the barrier functions of the epidermis, to prevent and/or treat symptoms related to dry skin or to improve and/or promote hydration of the keratinous layer. Finally, the invention relates to increasing the activity of PAD1 and/or PAD3 in the epidermis.
摘要:
The present invention relates to a compound with the following general formula (I): in which: R1 is a hydrocarbon chain of an unsaturated fatty acid from C12 to C24 including at least one unsaturation; and R2 and R3 are, independently or simultaneously: a hydrogen or a C1-C3 alkyl or a phenyl; and R4: a hydrogen atom or COR1′, where R1′ is a hydrocarbon chain of an unsaturated fatty acid from C12 to C24 including at least one unsaturation, advantageously 1 to 6 and preferably 1 to 4.
