Inhibitive effects of alkyl gallates on Hyaluronidase and collagenase

Abstract

A series of the gallate esters of n-alkanols (C1-C12) was examined to determine their inhibitory activities against hyaluronidase and collagenase. Hexyl, heptyl, octyl, nonyl, and decyl gallates inhibited both hyaluronidase and collagenase, and the most potent inhibitor was octyl gallate against both enzymes. Octyl 3, 5- dihydroxybenzoate showed inhibitory effects on hyaluronidase, whereas collagenase was inhibited by octyl 3, 4-dihydroxybenzoate.
