Application of topoisomerase assays in the evaluation of natural products as antitumor agents
(1999)Initially, DNA topoisomerase (topo) inhibitors found clinical applications as antibiotics and cancer chemotherapeutic agents. Recently, we demonstrated that plant flavonoids that inhibit mammalian topo I or topo II might ...

Discovery of anti-cancer activity for benzo[1,2,4]triazin-7-ones: Very strong correlation to pleurotin and thioredoxin reductase inhibition
(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 ...

Genistein as an Inducer of Tumor Cell Differentiation: Possible Mechanisms of Action
(1995)Decreased activity of either topoisomerases or tyrosine kinases has been implicated in the differentiation of a number of cell types. It is therefore conceivable that genistein, because of its reported ability to inhibit ...

Glucose-based spiro-isoxazolines: A new family of potent glycogen phosphorylase inhibitors
(2009)A series of glucopyranosylidene-spiro-isoxazolines was prepared through regio- and stereoselective [3+2]-cycloaddition between the methylene acetylated exo-glucal and aromatic nitrile oxides. The deprotected cycloadducts ...
