Induction of Quinone Reductase by Withanolides

open access: yesJournal of Natural Products, 2002
Thirty-seven naturally occurring withanolides (1-37), previously isolated in our laboratories, were evaluated for their potential to induce quinone reductase with cultured murine hepatoma cells (Hepa 1c1c7). Spiranoid (29, 32) and 18-functionalized withanolides (2-5, 7-9, 24) were found to be potent inducers of the enzyme, while 5alpha-substituted ...

Withanolides from Withania coagulans

open access: yesPhytochemistry, 2003
Two withanolides, 20beta-hydroxy-1-oxo-(22R)-witha-2,5,24-trienolide (1) and withacoagulin (2), along with a known withanolide, 17beta-hydroxy-14alpha, 20alpha-epoxy-1-oxo-(22R)-witha-3,5,24-trienolide (3) were isolated from Withania coagulans. Their structures were elucidated with the help of different spectroscopic techniques.
