Abstract

Exposure of ultraviolet (UV) light on the skin induces photoaging associated with up-regulated matrix metalloproteinase (MMP) activities and decreased collagen synthesis. We investigated the effects of panduratin A isolated from Kaempferia pandurata Roxb. on the expression of matrix metalloproteinase-1 (MMP-1) and type-1 procollagen in UV-irradiated human skin fibroblasts. Cultured human fibroblasts were irradiated with UV (20 mJ/cm2) and panduratin A was added into the medium of the fibroblast culture. The expressions of MMP-1 and type-1 procollagen levels were measured using Western blot analysis and RT-RCR. Panduratin A in the range of 0.001 - 0.1 μM significantly reduced the expression of MMP-1 and induced the expression of type-1 procollagen at the protein and mRNA gene levels. Panduratin A showed stronger activity than epigallocatechin 3-O-gallate (EGCG) known as a natural anti-aging agent. The results suggest that panduratin A can be a potential candidate for the prevention and treatment of skin aging brought about by UV.
