hydroxycoumarin/トウモロコシ

The action of the 4-hydroxycoumarins dicumarol and warfarin, antagonists of probable vitamin K type components of the plasma membrane electron-transport system, on plasma membrane redox activity of intact maize roots was compared. Both effectors inhibited electron transfer to extracellular

A glutathione S-transferase (GST) enzyme from corn (Zea mays L. Pioneer hybrid 3906) that is active with p-coumaric acid and other unsaturated phenylpropanoids was purified approximately 97-fold and characterized. The native enzyme appeared to be a monomer with a molecular mass of approximately 30

Rates of 7-ethoxycoumarin O-deethylation were determined in periportal and pericentral regions of the liver lobule in livers from corn oil- and beta-naphthoflavone-treated rats by monitoring the conversion of nonfluorescent 7-ethoxycoumarin to fluorescent 7-hydroxycoumarin with micro-light guides.
