Withaferin A (WFA), an active compound from Withania somnifera, is widely researched for its anti-inflammatory, cardioactive and central nervous system effects. In this study, we first investigated the possible barrier protective effects of WFA against pro-inflammatory responses in human umbilical

Withanolides are naturally occurring chemical compounds. They are secondary metabolites produced via oxidation of steroids and structurally consist of a steroid-backbone bound to a lactone or its derivatives. They are known to protect plants against herbivores and have medicinal value

PloS one, 7(6), e39065-e39065 (2012-06-22)
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
Narayan D Chaurasiya et al.
Plant cell reports, 31(10), 1889-1897 (2012-06-27)
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
