摘要:
The invention concerns a method for preparing a compound of formula (I), wherein: R3 and R1 represent in particular H and n is greater than 4, said preparation method including performing a Wittig-Horner reaction with a phosphonate on a lactol, so as to obtain a hydroxyester and, optionally a saponification reaction of said hydroxyester.
摘要:
Compounds, ceramide analogues, having a cyclic structure derived from cyclopropane, cyclobutane or cyclopentane, the ring bearing two chains consisting of an amide function. Each amide function is attached to the ring by the nitrogen atom of the function and carries a hydrocarbon chain derived from a fatty acid. The amide functions can be cis or trans relative to one another. Processes for the preparation of these novel compounds as well as pharmaceutical and/or cosmetic compositions containing them.

摘要:
The invention concerns novel polyunsaturated compounds of formula (I) wherein: R1 represents a R′1, -A-R′1 group, R′1 being selected from —COOH, —COOR3, —CONH2, —CONHR3, —CONR3 R4, —CHO, —CH2OH, —CH2OR5, and A represents a C2-C16 alkylene, alkenylene or alkynylene; R2 represents: an optionally substituted aryl group or an optionally substituted heteroaryl group; a sugar residue or, a fatty acid residue optionally branched and/or substituted preferably at the chain terminus and particularly by hydroxy, acetoxy radical or by an optionally protected amino radical; a —OC —(CH2)n CO-tocopheryl (alpha, beta or gamma or delta) group, with 2 $m(F) n $m(F) 10; a —R′2—O—R6 group, wherein R′2 is an optionally substituted arylene group or an optionally substituted heteroarylene group, and R6 represents a hydrogen atom, a straight or branched optionally substituted C 1-C 16 alkyl, a straight or branched optionally substituted C2-C16 alkenyl, or a straight or branched C2-C16 alkynyl group, an optionally substituted tocopheryl radical or the like, an amino acid residue, or a sugar residue. The invention also concerns the compositions, in particular cosmetic and/or dermatological compositions containing at least one compound of formula (I) as well as their use as whitening and/or depigmenting agent, and the cosmetic method using said compositions.
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.
