Application
Withaferin A was used to treat HEK293 cells to study its effect on cystic fibrosis inflammation.
Biochem/physiol Actions
Steroidal lactone that exhibits cytotoxicity towards tumor cells. Protective effects attributed to anti-lipid peroxidative, antioxidant and detoxifying functionality.
Withaferin A is a steroidal lactone that is isolated from the plant Withania somnifera. It has potent anti-inflammatory properties as it inhibits the activation of NF-κ B signaling pathway. The anti-tumor activity of Withaferin A is due to its ability to alter cytoskeletal architecture by binding annexin II and disrupting F actin cross-links. Withaferin A also inhibits angiogenesis by binding to vimentin and F-actin.
Preparation Note
Withaferin A yields a clear, colorless solution in methanol at 1 mg/ml.

The natural product withaferin A (WFA) exhibits antitumor and antiangiogenesis activity in vivo, which results from this drug's potent growth inhibitory activities. Here, we show that WFA binds to the intermediate filament (IF) protein, vimentin, by covalently modifying its cysteine
