Hazard Information | Back Directory | [Description]
Orientin is a flavone glycoside originally isolated from P. orientale that has diverse biological activities, including antioxidant, antibacterial, and anti-inflammatory properties.1,2,3,4 Orientin scavenges 2,2-diphenyl-1-picryl-hydrazyl (DPPH; Item No. 14805) radicals with an IC50 value of 316.21 μg/ml.2 It also decreases the cytopathic effects of parainfluenza type 3 virus with an IC50 value of 11.7 μg/ml and a cytotoxic concentration (CC50) value of 375 μg/ml in Hep-2 cells.3 Orientin (5-40 μM) inhibits LPS-induced barrier disruption, decreases the expression of toll-like receptor 4 (TLR4), phosphorylated p38, and NF-κB, and decreases TNF-α production and IL-6 secretion in a dose-dependent manner in human umbilical vein endothelial cells (HUVECs).4 It also prolongs survival in a mouse model of LPS-induced lethal endotoxemia when administered at a dose of 36 μg/animal 12 hours after LPS administration. | [Chemical Properties]
