Two nitrones, 3,3-diethyl-5,5-dimethylpyrroline 1-oxide (DEDMPO) and 3,3,5,5-tetramethylpyrroline 1-oxide (M4PO), were synthesized by the zinc/ammonium chloride reduction of appropiately substituted gamma-nitrocarbonyl compounds, followed by addition of methylmagnesium bromide to the resulting intermediate nitrones. The lipophilicities of these nitrones were estimated by

We compared neurotoxicity of piperine and low K+ on cultured cerebellar granule neurons. As considered from lactate dehydrogenase release and 3-(4,5-dimethylthiazol-2-yl)-2,5 diphenyl tetrazolium bromide reduction, both piperine and shifting from high K+ (25 mM) to low K+ (5.4 mM) were

We have studied the toxic effect of the alkylating antitumor drug N'-cyclohexyl-N-(2-chloroethyl)-N-nitrosourea (lomustine, CCNU) on Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) strains, alone and in presence of oxygen radical-scavenging substances [Vitamin E, stable nitroxyl radical 2,2,6,6-tetramethylpiperidine-N-oxyl (TMPO)

2,5,5-Trimethyl-1-pyrroline-N-oxide (M3PO) and 3,3,5,5-tetramethyl-1-pyrroline-N-oxide (M4PO) were examined for their potential as spin traps used in biological samples, and the results obtained for M3PO and M4PO were compared with those of 5,5-dimethyl-1-pyrroline-N-oxide (DMPO) reported previously. The rate constants for the reactions

When aqueous solutions of the spin trap 5,5'-dimethyl-1-pyrroline-N-oxide (DMPO) are treated with hydrogen peroxide in the presence of either FeII or light, the hydroxyl radical adduct DMPO-OH is formed, with a characteristic 4 line ESR spectrum. When oxy- or metmyoglobin
