Aplicación

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

Acciones bioquímicas o fisiológicas

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.

Nota de preparación

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

Withaferin A, the active component of Withania somnifera, causes cytotoxicity in a variety of tumor cell lines. In this study, we show that withaferin A inhibits constitutive and IL-6-induced phosphorylation of STAT3 (on Tyr705), but not IFN-γ-induced STAT1 phosphorylation. Withaferin
