Product Description
Cell permeable and potent angiogenesis inhibitor from the family of withanolides. Inhibits endothelial cells (HUVEC) sprouting in vitro (IC50=12nM) and in vivo. Exhibits antitumor, anti-inflammatory, radiosensitizing, and immunosuppressive properties. Potently inhibits NF-κB activation by preventing the TNF-induced activation of IκB kinase β (IKKβ). Affects AP1 transcription and induces cell death. Alters cytoskeletal architecture by covalently binding annexin II and stimulating its basal F-actin cross-linking activity which inhibits the migratory and invasive capability of endothelial cells. Displays neuronal regenerative properties. Targets the intermediate filament protein vimentin.
