生物活性

製品説明	Oxyresveratrol (Tetrahydroxystilbene, 2,3',4,5'-tetrahydroxystilbene), a naturally occurring compound particularly found in Morus alba L., exhibits a potent inhibitory effect on dopa oxidase activity of tyrosinase which catalyzes rate-limiting steps of melanin biosynthesis.
in vitro	Oxyresveratrol has been reported to inhibit β-amyloid-induced neurotoxicity in cultured cortical neurons and in vitro activity of β-secretase, an enzyme vital for the production of the Aβ protein. And it can also prevent neurotoxicity and DNA damage through its antioxidant properties in cultured neuronal cells. It shows modest inhibitory activity against H5N1 neuraminidase (an enzyme found in avian influenza virus), but strong inhibition against α-glucosidase, an enzyme responsible for the breaking down of starch and polysaccharides into glucose in the intestine^[1]. Oxyresveratrol is an effective radical scavenger^[2]. Oxyresveratrol protects hepatocytes against oxidative stress, mitochondrial damage, and resultant cell death. It induces activation of an antioxidant transcription factor, Nrf2, mediated through ERK phosphorylation^[3].
in vivo	Oxyresveratrol has been reported to undergo extensive hepatic metabolism and rapid urinary elimination, resulting in a short half-life time, and thereby restricting its clinical use. Moreover, its postulated function as a preventive agent for neurodegenerative disorders, such as AD or PD, appears to be hindered by its low ability to cross the blood-brain barrier (BBB). Despite its moderate in vitro inhibitory activity against herpes simplex virus type I (HSV-1), oxyresveratrol, in the form of topical cream, exhibits high therapeutic efficacy in mice cutaneously infected with HSV-1, with a potency comparable to that of the antiviral drug acyclovir^[1]. Oxyresveratrol ameliorates acute liver injury caused by CCl4 in mice^[3].

細胞アッセイ	細胞株	N9 microglial cells
	濃度	25, 50, and 100 μM
	反応時間	18 h
	実験の流れ	Cytotoxicity assays are performed by the trypan blue method. The cell cultures (N9 or C6 cell line, 2 mL medium each) are treated with 100 μL trypsin-EDTA, incubated for 5 min at 37℃, and then suspended with a pipette. The cell suspension is treated with 20 μL of 0.4% (wt/vol) trypan blue solution and the ratio of living/dead cells is determined immediately by counting the cells in a 20 μL aliquot in a Neubauer chamber under a microscope.
動物実験	動物モデル	C57BL/6 male mice
	投薬量	10 or 30 mg/kg
	投与方法	oral administration
