Withaferin A (WFA) is a steroidal lactone present in Withania somnifera which has been shown in vitro to bind to the intermediate filament protein, vimentin. Based upon its affinity for vimentin, it has been proposed that WFA can be used

Withanolides are pharmaceutically important C(28)-phytochemicals produced in most prodigal amounts and diversified forms by Withania somnifera. Metabolic origin of withanolides from triterpenoid pathway intermediates implies that isoprenogenesis could significantly govern withanolide production. In plants, isoprenogenesis occurs via two routes: mevalonate

Sorafenib (SO), a multikinase-targeted inhibitor in clinical trials for papillary and anaplastic cancers, shows limited efficacy with moderate toxicity. Withaferin A (WA), a natural withanolide, shows potent preclinical anticancer activity in thyroid cancers through multiple cytotoxic mechanisms including heat-shock protein
