Description:
WITHAFERIN A, also referred to as D004, NSC 101088, used as an important medicinal herb for over 3000 years, is a steroidal lactone derived from Acnistus arborescens, Withania somnifera and other members of Solanaceae family. This natural product has wide range of pharmacological application comprising of anti-obesity, anti-inflammatory, anti-neoplastic, antiangiogenic, etc. WITHAFERIN A inhibits endothelial cells (HUVEC) sprouting (in vitro: IC50 = 12 nM and in vivo), activation of IKKβ (IC50= 0.5-1 μM), chymotrypsin-like activity of the 20S proteasome and cell proliferation of uveal melanoma cells (IC50= 0.90, 1.66, and 2.42 μM for OMM2.3, 92.1, and MEL290 cells, respectively). In vivo: studies using WA reduced tumor growth in 100% of animals (p = 0.015) In vitro: studies shows that WA is a potent drug that inhibits cell proliferation, shifts cell cycle arrest, and induces apoptosis in multiple UM cell lines

1.Withaferin-A-A Natural Anticancer Agent with Pleitropic Mechanisms of Action.
Lee IC1, Choi BY2. Int J Mol Sci. 2016 Mar 4;17(3). pii: E290. doi: 10.3390/ijms17030290.
Cancer, being the second leading cause of mortality, exists as a formidable health challenge. In spite of our enormous efforts, the emerging complexities in the molecular nature of disease progression limit the real success in finding an effective cancer cure. It is now conceivable that cancer is, in fact, a progressive illness, and the morbidity and mortality from cancer can be reduced by interfering with various oncogenic signaling pathways. A wide variety of structurally diverse classes of bioactive phytochemicals have been shown to exert anticancer effects in a large number of preclinical studies. Multiple lines of evidence suggest that withaferin-A can prevent the development of cancers of various histotypes. Accumulating data from different rodent models and cell culture experiments have revealed that withaferin-A suppresses experimentally induced carcinogenesis, largely by virtue of its potent anti-oxidative, anti-inflammatory, anti-proliferative and apoptosis-inducing properties.

CONTEXT: Overdose of acetaminophen (APAP) is common in humans and is often associated with hepatic damage. Withania somnifera (L.) Dunal (Solanaceae) shows multiple pharmacological activities including antioxidant and anti-inflammatory potential.
3.Withaferin A induces heme oxygenase (HO-1) expression in endothelial cells via activation of the Keap1/Nrf2 pathway.

Withaferin A (WA), a natural phytochemical derived from the plant Withania somnifera, is a well-studied bioactive compound exerting a broad spectrum of health promoting effects. To gain better insight in the potential therapeutic capacity of WA, we evaluated the transcriptional effects of WA on primary human umbilical vein endothelial cells (HUVECs) and an endothelial cell line (EA.hy926). RNA microarray analysis of WA treated HUVEC cells demonstrated increased expression of the antioxidant gene heme oxygenase (HO-1). Transcriptional regulation of this gene is strongly dependent on the transcription factor NF-E2-related factor 2 (Nrf2), which senses chemical changes in the cell and coordinates transcriptional responses to maintain chemical homeostasis via expression of antioxidant genes and cytoprotective Phase II detoxifying enzymes. Under normal conditions, Nrf2 is kept in the cytoplasm by Kelch-like ECH-associated protein 1 (Keap1), an adaptor protein controlling the half-life of Nrf2 via constant proteasomal degradation.
4.Withaferin-A suppress AKT induced tumor growth in colorectal cancer cells.
Suman S1, Das TP1, Sirimulla S2, Alatassi H3, Ankem MK1, Damodaran C1. Oncotarget. 2016 Feb 12. doi: 10.18632/oncotarget.7351. [Epub ahead of print]
The oncogenic activation of AKT gene has emerged as a key determinant of the aggressiveness of colorectal cancer (CRC); hence, research has focused on targeting AKT signaling for the treatment of advanced stages of CRC. In this study, we explored the anti-tumorigenic effects of withaferin A (WA) on CRC cells overexpressing AKT in preclinical (in vitro and in vivo) models. Our results indicated that WA, a natural compound, resulted in significant inhibition of AKT activity and led to the inhibition of cell proliferation, migration and invasion by downregulating the epithelial to mesenchymal transition (EMT) markers in CRC cells overexpressing AKT. The oral administration of WA significantly suppressed AKT-induced aggressive tumor growth in a xenograft model. Molecular analysis revealed that the decreased expression of AKT and its downstream pro-survival signaling molecules may be responsible for tumor inhibition. Further, significant inhibition of some important EMT markers, i.
