Discovery of anti-cancer activity for benzo[1,2,4]triazin-7-ones: Very strong correlation to pleurotin and thioredoxin reductase inhibition
Sweeney, M.; Coyle, R.; Kavanagh, P.; Berezin, Andrey A.; Lo Re, D.; Zissimou, Georgia A.; Koutentis, Panayiotis Andreas; Carty, Michael P.; Aldabbagh, Fawaz (2016)The thioredoxin (Trx)–thioredoxin reductase (TrxR) system plays a key role in maintaining the cellular redox balance with Trx being over-expressed in a number of cancers. Inhibition of TrxR is an important strategy for ...
