Anti-inflammatory Terpenoids from the Leaves and Twigs of Dysoxylum gotadhora.
Nine new terpenoids (1-3, 5-10), including three cyclolanostane triterpenoids (1-3) and six isopimarane diterpenoids (5-10), along with six known terpenoids (4, 11-15), were isolated from the leavesExpand

Inactivation of protein tyrosine phosphatases by dietary isothiocyanates.
Isothiocyanates are bioactive dietary phytochemicals that react readily with protein thiol groups. We find that isothiocyanates are time-dependent inactivators of cysteine-dependent protein tyrosineExpand

Inhibition of thioredoxin reductase by alantolactone prompts oxidative stress-mediated apoptosis of HeLa cells.
The mammalian thioredoxin reductase (TrxR) isoenzymes, TrxR1 in cytosol or nucleus, TrxR2 in mitochondria, and TrxR3 in testis, are essential seleno-flavoenzymes with a conserved penultimateExpand
