6'-O-Galloyl paeoniflorin
Catalog No: CFN96175
6'-O-Galloylpaeoniflorin (GPF) may be developed as a cytoprotector against ROS-mediated oxidative stress, GPF demonstrates a significant scavenging capacity against the 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical, H2O2-generated intracellular reactive oxygen species (ROS), the superoxide anion radical (O2 -), and the hydroxyl radical (•OH); GPF also can safeguarde HaCaT keratinocytes against H2O2-provoked apoptotic cell death and attenuated oxidative macromolecular damage to DNA, lipids, and proteins; GPF exerts its cytoprotective actions in keratinocytes at least in part by decreasing the number of DNA strand breaks, the levels of 8-isoprostane (a stable end-product of lipid peroxidation), and the formation of carbonylated protein species. GPF shows strong androgen receptor (AR) binding activity.
6-Prenylnaringenin
Catalog No: CFN92017
6-Prenylnaringenin is an isomer of the potent phytoestrogen, 8-prenylnaringenin. It exhibits both mixed and non-competitive inhibitory characteristics against tyrosinase, tyrosinase is the rate-limiting enzyme for the production of melanin and other pigments via the oxidation of l-tyrosine. 6-Prenylnaringenin has anti-cancer potential , dose-dependent reduction of cellular proliferation of human PC-3 prostate cancer and UO.31 renal carcinoma cells upon treatment. 6-Prenylnaringenin can inhibit 12-O-tetradecanoylphorbol 13-acetate (TPA)-induced inflammation (1μg/ear) in mice, it also exhibits inhibitory effects on skin-tumor promotion in anin vivo two-stagemouse-skin carcinogenesis test based on 7,12-dimethylbenz[a]- anthracene (DMBA) as initiator and with TPA as promoter.
