NOVEL ESTERS OF N-ACYL DERIVATIVES OF AMINO ACIDS AND DIOLS, METHOD FOR PREPARING SAME, AND USE THEREOF IN COSMETICS AND AS A DRUG

摘要

A compound of formula (I): R′—O-A-O—R″″, in which R′ and R″ are a hydrogen atom or a monovalent radical of formula (IIa), or a monovalent radical of formula (IIb), it being understood that at least one of the radicals R′ or R″ is not a hydrogen atom and that, when none of the radicals R′ and R″ is a hydrogen atom, R′ and R″ are identical, and in which A is a divalent radical of formula (III): —CH(X1)-[C(X2)(X3)]p-CH(X4) in which X1, X2, X3 and X4 are identical or different and are either a hydrogen atom or a methyl radical or an ethyl radical, and p is an integer greater than or equal to 1 and less than or equal to 6. Also the method for preparing the compound of formula (I) and to the use thereof in cosmetics and as a drug.

R1 represents an aliphatic radical, saturated or unsaturated, linear or branched, comprising 7 to 30 carbon atoms, R2 represents a hydrogen atom or a radical chosen from the following radicals: methyl, isopropyl, isobutyl, 1-methyl propyl, hydroxymethyl, 1-hydroxy ethyl, thiomethyl, 2-methylthio ethyl, 4-aminobutyl, 3-guanidino propyl, 3-ureido propyl, (1-amino carbonyl)methyl, 2-(amino carbonyl)ethyl, benzyl, 4-hydroxy benzyl, 3,4-dihydroxy benzyl, [1H-indol-3-yl]methyl, (1H-imidazol-4-yl)methyl, 3-amino propyl, and R3 represents a hydrogen atom or a methyl radical; or a monovalent radical of formula (IIb):in which:
R1 is as defined in formula (IIa) and R4 represents a hydrogen atom or a hydroxy radical,it being understood that at least one of the radicals R′ or R″ is not a hydrogen atom and that, when none of the radicals R′ and R″ is a hydrogen atom, R′ and R″ are identical,and formula (I) in which A represents the divalent radical of formula (III):
—CH(X1)-[C(X2)(X3)]p-CH(X4)-  (III)in which:
X1, X2, X3 and X4, identical or different, are either a hydrogen atom, or a methyl radical, or an ethyl radical, and p is an integer number greater than or equal to 1 and less than or equal to 6.
