There has been a recent renewal of interest in the use of monoamine oxidase inhibitors in psychiatry. The concurrent administration of anaesthetic agents, particularly narcotic analgesics, is often a cause for concern. Although many monoamine oxidase inhibitor-drug interactions have been reported, in practice it is only the interaction with pethidine which has led to fatalities. What is not app...

BACKGROUND/AIMS 3,4-Dimethoxy-2-phenylethylamine is catalyzed to its aldehyde derivative by monoamine oxidase B, but the subsequent oxidation into the corresponding acid has not yet been studied. Oxidation of aromatic aldehydes is catalyzed mainly by aldehyde dehydrogenase and aldehyde oxidase. METHODS The present study examines the metabolism of 3,4-dimethoxy-2-phenylethylamine in vitro and ...

In this study, we designed a method to manufacture elevated fermented green tea by using Monascus pilosus, which is known as a functional microbe, and observe its antioxidant abilities and quality characteristics. The water-soluble substance (WSS) content of the fermented tea by M. pilosus (FTM) was lower than that of the non-fermented tea (NFT), although the alcohol-insoluble substance (AIS) c...

Aminoacetonitrile (AAN) decomposes with the formation of a substance that is a potent inhibitor of cytochrome oxidase. The inhibitor is probably cyanide. Connective tissue contains cytochrome oxidase that varies in amount with the maturity of the tissue and is also inhibited by the product of AAN decomposition.

E&acts of pineapple stem tissue constitute the most potent known source of indoleacetic acid oxidase, despite the presence of an inhibitor which is difficult to remove without simultaneously removing some other factor necessary for maximal activity (I). Dialysis invariably lowers the enzyme activity as compared with photolysis, and even prolonged photolysis is never completely effective in remo...

1 Incubation of human eosinophils in BSA-coated tissue culture plates resulted in time-dependent adhesion and attendant activation of the NADPH oxidase that were both inhibited (by >85%) by blocking antibodies raised against CD11b and CD18. 2 SB 203580, an inhibitor of p38 mitogen-activated protein (MAP) kinase, did not influence adhesion but inhibited superoxide anion generation (pIC50=-6.57)....
