Abstract

Skin aging caused by excessive exposure to ultraviolet is known as photoaging. The mechanism underlying skin photoaging relates to collagen degradation in the extracellular matrix (ECM) by overexpression of matrix metalloproteinases-1 (MMP-1). Gallic acid is a phenolic antioxidant found in many types of plants and can be used as an anti-photoaging agent due to its antioxidant activity. This study aims to determine the potential effect of gallic acid as an anti-photoaging against MMP-1 using in silico molecular docking. The stages included gallic acid structure optimization using the HyperChem 8, preparation of protein target MMP-1 (PDB ID: 966C) using the Chimera1.10.1, validation the molecular docking protocol, and docking gallic acid on MMP-1 with the Autodock 1.5.6. The results showed that gallic acid had an affinity for MMP-1 with a binding energy of -6.0 kcal/mol. There are similar amino acid residues in hydrogen bonds between the native ligand RS2 with MMP-1 and gallic acid with MMP-1, namely ALA 182, LEU 181, and HIS 218. The results suggest that gallic acid has the potential as the anti-photoaging agent through the inhibition of the MMP-1 enzyme.

Abstract

Hyperpigmentation is a skin problem caused by excessive melanin production due to continuous ultraviolet (UV) radiation. Kojic acid inhibiting melanin synthesis by tyrosinase enzyme is a prevalent treatment for hyperpigmentation. This study aims to determine the potential of chlorogenic acid and kojic acid as an anti-hyperpigmentation against tyrosinase using in silico molecular docking. The docking process involved optimizing chlorogenic acid and kojic acid structures, preparing tyrosinase protein (PDB ID: 5M8O), validating the molecular docking method, and docking of chlorogenic acid and kojic acid on tyrosinase. The binding energy of chlorogenic acid and kojic acid were -4.59 kcal/mol and -3.75 kcal/mol, while the binding energy of 0TR native ligand was -5.02 kcal/mol. The interaction of chlorogenic acid to tyrosinase involved ARG 321 and ARG 374 residues. The results suggest that chlorogenic acid and kojic acid has the potential as anti-hyperpigmentation agents through inhibition of the tyrosinase enzyme.
