Vitexin (Standard) is a reference standard for research and analysis in studies involving Vitexin. 1. Vitexin has antinociceptive and antispasmodic activities. 2. Vitexin exhibits a prominent first-pass effect. 3. Vitexin has antioxidant, antimyeloperoxidase, and α-glucosidase inhibitory activities. 4. Vitexin can either inhibit or induce activities of CYP2C11 and CYP3A1. 5. Vitexin induces the novel p53-dependent metastatic and apoptotic pathway. 6. Vitexin protects brain against cerebral I/R injury, and this effect may be regulated by mitogen-activated protein kinase (MAPK) and apoptosis signaling pathways.
