Journal ArticleDOI
The isolation and antioxidative effects of vitexin from Acer palmatum.
Jin-Hwa Kim,Bum Chun Lee,Jin Hui Kim,Gwan Sub Sim,Dong-Hwan Lee,Kyung Eun Lee,Yeo Pyo Yun,Hyeong Bae Pyo +7 more
TL;DR: The results show that oxidation of 5-(6-)chloromethyl-2′,7′-dichlorodihydrofluorescein diacetate is inhibited by vitexin effectively and that viteXin has a potent free radical scavenging activity in UVB-irradiated HDFs.
Journal ArticleDOI
Structure activity relationship of antioxidative property of flavonoids and inhibitory effect on matrix metalloproteinase activity in UVA-irradiated human dermal fibroblast
Gwan-Sub Sim,Bum-Chun Lee,Ho Seung Cho,Jae Woong Lee,Jin-Hwa Kim,Dong-Hwan Lee,Jin-Hui Kim,Hyeong-Bae Pyo,Dong Cheul Moon,Ki-Wan Oh,Yeo Pyo Yun,Jin Tae Hong +11 more
TL;DR: Results suggested the UVA induced antioxidative activity and inhibitory effects of flavonoids on the collagenase in human dermal fibroblasts depends on the number of OH group in the flavonoid structure, and those with a higher number ofOH group may be more useful in the prevention of UV stressed skin aging.
Journal ArticleDOI
Anti-oxidative and photo-protective effects of coumarins isolated from Fraxinus chinensis.
Bum-Chun Lee,So Yong Lee,Hwa Jeong Lee,Gwan-Sub Sim,Jin-Hui Kim,Jin-Hwa Kim,Young-Ho Cho,Dong-Hwan Lee,Hyeong-Bae Pyo,Tae-Boo Choe,Dong Cheul Moon,Yeo Pyo Yun,Jin Tae Hong +12 more
TL;DR: FCE and one of its components, esculetin, were predicted to be potentially useful as ingredients in cosmetics for protecting against photoaging and showed strong antioxidative activities.
Journal ArticleDOI
p21-activated kinase 4 critically regulates melanogenesis via activation of the CREB/MITF and β-catenin/MITF pathways.
Cheong Yong Yun,Soon Tae You,Jin-Hwa Kim,Jin H. Chung,Sang-Bae Han,Eun Young Shin,Eung-Gook Kim +6 more
TL;DR: Evidence is provided that PAK4 promotes α-MSH/UVB-induced melanogenesis via the CREB and Wnt/β-catenin signaling pathways and suggest that PAk4 may be a potential therapeutic target in pigmentation disorders.
Journal ArticleDOI
Pratol, an O-Methylated Flavone, Induces Melanogenesis in B16F10 Melanoma Cells via p-p38 and p-JNK Upregulation
TL;DR: The results showed that pratol significantly increased melanin content and tyrosinase activity in the cells without being cytotoxic, and suggest that, owing to its multi-functional properties,Pratol may be a potential tanning agent or a therapeutic agent for hair depigmentation in the cosmetic industry.
