Taccalonolide A
Taccalonolide A is a withanolide. Taccalonolide A is a natural product found in Tacca plantaginea and Tacca chantrieri with data available. Taccalonolide A is a microtubule stabilizer, which is a steroid isolated from Tacca chantrieri, with cytotoxic and antimalarial activities[1][2]. Taccalonolide A causes G2-M accumulation, Bcl-2 phosphorylation and initiation of apoptosis[1]. Taccalonolide A is effective in vitro against cell lines that overexpress P-glycoprotein (Pgp) and multidrug resistance protein 7 (MRP7), with an IC50 of 622 nM for SK-OV-3 cells[3].
Withaferin A
Withaferin A is a withanolide that is 5,6:22,26-diepoxyergosta-2,24-diene-1,26-dione substituted by hydroxy groups at positions 4 and 27 (the 4beta,5beta,6beta,22R stereoisomer). Isolated from Physalis longifolia, it exhibits cytotoxic activity. It has a role as an antineoplastic agent and an apoptosis inducer. It is a delta-lactone, a 4-hydroxy steroid, an enone, an ergostanoid, a secondary alcohol, a withanolide, a 27-hydroxy steroid, a primary alcohol and an epoxy steroid. Ashwagandha is a popular Ayurvedic herb used as a general tonic, to increase energy and reduce stress. Ashwagandha has not been implicated in causing serum enzyme elevations during therapy, but recently has been implicated in rare cases of clinically apparent liver injury. Withaferin A is a natural product found in Vassobia breviflora, Withania somnifera, and other organisms with data available. A withanolide that is 5,6:22,26-diepoxyergosta-2,24-diene-1,26-dione substituted by hydroxy groups at positions 4 and 27 (the 4beta,5beta,6beta,22R stereoisomer). Isolated from Physalis longifolia, it exhibits cytotoxic activity. Withaferin A is a steroidal lactone isolated from Withania somnifera, inhibits NF-kB activation and targets vimentin, with potent antiinflammatory and anticancer activities. Withaferin A is an inhibitor of endothelial protein C receptor (EPCR) shedding.

Taccalonolide B is a natural product found in Tacca plantaginea and Tacca chantrieri with data available. Taccalonolide B is microtubule stabilizer isolated from Tacca plantaginea, with antitumor activity. Taccalonolide B is effective in vitro against cell lines that overexpress P-glycoprotein (Pgp) and multidrug-resistance protein (MRP7).

Withanolide
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. 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.
