Withanolide

C28H38O6 (470.2668248)

Withanolides, which are extracted from Withania somnifera, are employed in the treatment of arthritis and are known to be potent inhibitors of angiogenesis, inflammation and oxidative stress. Withanolides can indeed inhibit the activation of NF-κB and NF-κB-regulated gene expression, which could explain their anti-arthritic actions. W. somnifera root powder has suppressive effect on arthritis by reducing amplification and propagation of the inflammatory response, without causing any gastric damage.

Withanolide

C28H38O6 (470.2668248)

A withanolide that is 5,6:22,26-diepoxyergosta-2,24-diene-1,26-dione substituted by hydroxy groups at positions 4 and 22 (the 4beta,5beta,6beta,22R stereoisomer). Isolated from Tubocapsicum anomalum and Withania somnifera, it exhibits cytotoxic activity.
