Descripción

Application

Withaferin A was used to treat HEK293 cells to study its effect on cystic fibrosis inflammation.

Biochem/physiol Actions

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.

Steroidal lactone that exhibits cytotoxicity towards tumor cells. Protective effects attributed to anti-lipid peroxidative, antioxidant and detoxifying functionality.

Preparation Note

Withaferin A yields a clear, colorless solution in methanol at 1 mg/ml.
