Abstract:
A hydroxycinnamic acid derivative compound is provided to realize improved anti-oxidation property and skin permeability, effects of inhibiting active oxygen and melanin generation and stimulating procollagen generation, thereby providing a cosmetic composition for improving wrinkles and whitening. A hydroxycinnamic acid derivative compound has an adamantyl amide linking group and is represented by the following formula I. In formula I, R1 is H or a C1-C7 alkyl group; and A is -CH=CH- or -CH2-CH2-. The hydroxycinnamic acid derivative compound is obtained by the method comprising the steps of: (1) substituting the hydroxyl group of hydroxycinnamic acid with an acetyl group to provide an acetylated compound; (2) reacting the acetylated compound with ethyl chloroformate and oleophilic group-containing adamantanamine to provide an amide compound; and (3) hydrolyzing the acetyl group of the amide compound.
Abstract:
2,3-Dihydroxybenzoic acid derivatives, a preparation method thereof, and a skin-whitening cosmetic composition containing the same compounds are provided to inhibit activity of tyrosinase and melanin formation while cytotoxicity of the compounds is very low, so that the compounds are useful for improvement of pigmentation in the skin. The method for preparing the 2,3-dihydroxybenzoic acid derivatives represented by the formula(1) comprises the steps of: (A) reacting 2,3-dihydroxybenzoic acid with acetic acid anhydride in the presence of base to prepare a 2,3-diacetyloxybenzoic acid compound represented by the formula(2); (B) preparing an amide compound represented by the formula(3) from the 2,3-diacetyloxybenzoic acid compound by using ethylchloroformate and amine having a lipophilic group; and (C) hydrolyzing an acetyl group of the amide compound represented by formula (3) to prepare 2,3-dihydroxybenzoic acid represented by the formula (1), wherein R is 4-ethoxyphenyl, 2-cyclohexenylethyl, cycloheptyl, cyclohexyl, tert-octyl, 4-isopropylphenyl, 2,3-dihydrobenzo[1,4]dioxin-7-yl, benzo[1,3]-dioxol-6-yl or adamantyl-1-yl; and the amine having the lipophilic group is an amine selected from 4-ethoxyphenylamine, 2-cyclohexenylethylamine, cycloheptylamine, cyclohexylamine, tert-octylamine, 4-isopropylphenylamine, 2,3-dihydrobenzo[1,4]dioxin-7-amine, benzo[1,3]-dioxol-6-amine or adamantyl-1-amine.
