Replaces Prod. #: ALX-350-153

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). Elicits IKKß hyperphosphorylation concomitant with inhibition of its kinase activity. 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. Targets the intermediate filament protein vimentin. Displays neuronal regenerative properties. It induced significant regeneration of both axons and dendrites in an A β-induced axonal atrophy model.
