产品描述:从Vitisvinifera提取得到的,Resveratrol的二聚体,可有效抑制CYP家族,Ki值在0.5-20μM之间。ε-Viniferin具有强大的抗氧化活性。 trans-ε-Viniferin is a stilbene polyphenol and dimer of trans-resveratrol that has been found in various red wines. It induces disaggregation of aggregated amyloid-β (1-42) (Aβ42) fibrils and decreases Aβ42- and IL-1β-induced release of TNF-α and IL-6 in primary mouse neuron and astrocyte cocultures. trans-ε-Viniferin reduces cytotoxicity induced by truncated huntingtin (Htt) in PC12 cells. It also reduces production of reactive oxygen species (ROS), mitochondrial dysfunction, and PGC-1α depletion and increases protein levels and deacetylase activity of sirtuin 3 (SIRT3) in cells expressing mutant Htt. trans-ε-Viniferin inhibits calcium-activated chloride channel currents in HT-29 cells. In vivo, trans-ε-viniferin reduces rotavirus-induced secretory diarrhea in mice without affecting the rotaviral infection. Dietary administration of trans-ε-viniferin reduces hepatic triglyceride accumulation and body weight increases in a mouse model of diet-induced obesity.
