    • Provided is a 3,5-dihydroxybenzoic acid derivative, which shows an elastase inhibitory effect and an excellent effect of scavenging free radicals generated by UV irradiation, has an excellent anti-aging effect, and is useful for an anti-aging cosmetic composition. The 3,5-dihydroxybenzoic acid derivative is a compound represented by a formula 1, substituted with hydroxyl groups at 3,5-position thereof and the amide group being substituted with a bulky substituent. The 3,5-dihydroxybenzoic acid derivative is obtained by the method comprising the steps of: (A) reacting 3,5-dihydroxybenzoic acid with acetic anhydride to form 3,5-diacetyloxybenzoic acid; (B) forming an amide compound from the 3,5-diacetyloxybenzoic acid by using ethyl chloroformate and an oleophilic group; and (C) hydrolyzing the acetyl group of the amide compound to provide a 3,5-dihydroxybenzoic acid derivative.
    • 本发明提供一种3,5-二羟基苯甲酸衍生物,其显示出弹性蛋白酶抑制作用,并且通过UV照射产生的清除自由基的优异效果,具有优异的抗老化作用,并且可用于抗老化化妆品组合物。 3,5-二羟基苯甲酸衍生物是由式3表示的化合物,其3,5-位被羟基取代且酰胺基被大体积取代基取代。 3,5-二羟基苯甲酸衍生物通过包括以下步骤的方法获得:(A)使3,5-二羟基苯甲酸与乙酸酐反应形成3,5-二乙酰氧基苯甲酸; (B)通过使用氯甲酸乙酯和亲油基团由3,5-二乙酰氧基苯甲酸形成酰胺化合物; 和(C)水解酰胺化合物的乙酰基得到3,5-二羟基苯甲酸衍生物。
