The present invention provides a compound having functionality to inhibit melanogenesis, enhance collagen-producing action and corneal wound healing. a variety of experimental results have proved that the compound includes a high inhibiting activity, which especially acts on reducing the gene expression of MMP-9 and MITF in human normal skin fibroblasts. In addition, based on the high inhibiting activity of the compound acting on the gene expression of MMP-9 and MITF, simultaneously, the collagen and melanin production in human normal skin fibroblasts are respectively enhanced and decreased.不發明係提供一種具黑色素產生抑制作用以及膠原蛋白產生促進作用之化合物,實驗結果係證實該化合物係具有高度的抑制活性,特別是作用於人類皮膚纖維母細胞之中的MMP-9的基因表現量以及MITF的基因表現量。再者,該化合物可顯著地抑制MMP-9基因表現量與MITF基因表現量,人類纖維母細胞之中的膠原蛋白生成量係同時被提升,且人類纖維母細胞之中的黑色素係同時被抑制。S1~S5‧‧‧方法步驟
