due to the destruction of the ozone layer. Our skin is more exposed to UV radiation and often suffers from various harmful effects of UV. Melanin prodcution in human skin is an important defense mechanism against UV and a major determinant of skin color. Melanocytes residing within the basal layer of the epidermis synthesize melanin in specialized organelles, designated as melanosomes, by coord...
متن کاملPrimary Investigation for the Mechanism of Biatractylolide from Atractylodis Macrocephalae Rhizoma as an Acetylcholinesterase Inhibitor
Biatractylolide was isolated from ethyl acetate extract of dried Atractylodis Macrocephalae Rhizoma root by multistep chromatographic processing. Structure of biatractylolide was confirmed by (1)H-NMR and (13)C-NMR. The IC50 on acetylcholinesterase (AChE) activity was 6.5458 μg/mL when the control IC50 value of huperzine A was 0.0192 μg/mL. Molecular Docking Software (MOE) was used to discover ...
متن کاملMelanogenesis Inhibition by Homoisoflavavone Sappanone A from Caesalpinia sappan
Homoisoflavanone, sappanone A, was isolated from Caesalpinia sappan and proven to dose-dependently inhibit both melanogenesis and cellular tyrosinase activity via repressing tyrosinase gene expression in mouse B16 melanoma cells. To our knowledge, sappanone A is the first homoisoflavanone to be discovered with melanogenesis inhibitory activity. Our results give a new impetus to the future searc...
