Microbiological and chemical dehydrogenation of withaferin A

Folia Microbiologica, 1987
Arthrobacter simplex dehydrogenated withaferin A to 4-dehydrowithaferin A but it was not able to dehydrogenate this substrate in position 27. 27-Dehydrowithaferin A was prepared chemically using pyridinium chlorochromate. Whereas 4-dehydrowithaferin A surpassed in its effect on leukemic (388 cells the original compound and all its derivates synthesized

The effect of withaferin A on plant cells

European Journal of Cancer (1965), 1971
Abstract Withaferin A in a concentration of 0·01-0·5% in water inhibited the growth of Allium cepa roots. Furthermore, withaferin A induced c-tumor formation and lateral root formation on treated roots. Microscopical examination of withaferin A-treated root tip cells showed a clear arrest at metaphase as soon as 2 hr after treatment.

Withaferin A is a potent inhibitor of angiogenesis

Angiogenesis, 2004
The medicinal plant Withania somnifera is widely researched for its anti-inflammatory, cardioactive and central nervous system effects. In Ayurveda , the major Traditional Indian medicine system, extracts from W. somnifera are distinctively employed for the treatment of arthritis and menstrual disorders.

Withaferin-A—A Natural Anticancer Agent with Pleitropic Mechanisms of Action

International Journal of Molecular Sciences, 2016
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

Antiplatelet, anticoagulant, and profibrinolytic activities of withaferin A

Vascular Pharmacology, 2014
Withaferin A (WFA), an active compound from Withania somnifera, is widely researched for its anti-inflammatory, cardioactive and central nervous system effects. However, antiplatelet, anticoagulant, and profibrinolytic properties of WFA have not been studied.

The Use of Withaferin A to Study Intermediate Filaments

2016
Withaferin A (WFA), initially identified as a compound that inhibits experimental angiogenesis, has been shown to bind to soluble vimentin (sVim) and other type III intermediate filament (IF) proteins. We review WFA's dose-related activities (Section 1), examining nanomolar concentrations effects on sVim in cell proliferation and submicromolar effects ...

Withaferin A and its potential role in glioblastoma (GBM)

Journal of Neuro-Oncology, 2016
Within the Ayurvedic medical tradition of India, Ashwagandha (Withania somnifera) is a well-known herb. A large number of withanolides have been isolated from both its roots and its leaves and many have been assessed for their pharmacological activities. Amongst them, Withaferin A is one of its most bioactive phytoconstituents.

Effect of Withaferin A on cells in tissue culture

Zeitschrift f�r Krebsforschung und Klinische Onkologie, 1973
The experiments were performed with embryonal chicken fibroblasts, HeLa cells and H. Ep. 2 (human larynx carcinoma) in hanging drop cultures. They confirm the results obtained with tumor bearing mice. Withaferin A is acting as a mitotic poison and arrests the tumor cells at metaphase. Its effect on cells may be compared to that of colchicine, alkaloids

Microbial transformations of natural antitumor agents. 23. conversion of withaferin-A to 12β- and 15β-hydroxy derivatives of withaferin-A.

Steroids, 1982
Microbial transformation experiments were conducted with the antitumor lactone withaferin-A. Cunninghamella elegans NRRL 1393 transformed withaferin-A (1a) to 15 beta-hydroxywithaferin-A (2a) and 12 beta-hydroxy-withaferin-A (3a). The hydroxylated metabolites were isolated by solvent extraction and were purified by column and thin-layer chromatography.

Production of Withaferin A in Shoot Cultures of Withania somnifera

Planta Medica, 2001
Multiple shoot cultures of Withania somnifera were established from single shoot tip explants and their potential for the production of two principle withanolides, withaferin A and withanolide D was investigated. Shoot tips grown on MS medium supplemented with BA (1 mg l(-1)) induced 10.0 +/- 1.15 microshoots per explants and shoot cultures accumulated
