| Hazard Information | Back Directory | [Description]
Withaferin A (5119-48-2) displays potent antiangiogenesis activity inhibiting endothelial cell sprouting in vitro?(IC50?= 12 nM) and?in vivo.1?Potently inhibits NF-κB activation by preventing TNFα-induced activation of IKKβ.2?Covalently binds to the intermediate filament protein, vimentin3?inducing its disassembly and serine 56 phosphorylation4. Inhibits reactive gliosis and blocks TNFα-mediated neuronal apoptosis in?in vivo?models.5 | [Chemical Properties]
Solid | [Uses]
Withaferin A is a promising anticancer constituent of Ayurvedic medicinal plant Withania somnifera. Withaferin A showed potent cytotoxicity against human head and neck squamous cell carcinoma (JMAR and MDA-1986). | [Definition]
ChEBI: A withanolide that is 5,6:22,26-diepoxyergosta-2,24-diene-1,26-dione substituted by hydroxy groups at positions 4 and 27 (the 4beta,5beta,6beta,22R stereoisomer). Isolated from Phys
lis longifolia, it exhibits cytotoxic activity. | [Biological Activity]
Steroid lactone that displays anti-inflammatory, antitumor and antiangiogenic activity. Inhibits endothelial cells (HUVEC) spouting in vitro (IC 50 = 12 nM) and in vivo . Prevents NF- κ B activation by inhibiting activation of IKK β . Also inhibits chymotrypsin-like activity of the 20S proteasome. | [target]
