Oxidative stress is believed to play a role in the pathogenesis of several diseases, including diabetes and inborn errors of metabolism. The types of oxidative damage observed in these pathologies have been attributed to the excessive production of r

Hereditary tyrosinemia type I (HT1) is an inborn metabolic error characterized by hepatorenal dysfunction. Affected patients excrete large quantities of succinylacetone (SA), a tyrosine catabolite believed to be involved in the pathogenesis of HT1. A

Aminoacetone (AA) is a threonine and glycine catabolite long known to accumulate in cri-du-chat and threoninemia syndromes and, more recently, implicated as a contributing source of methylglyoxal (MG) in diabetes mellitus. Oxidation of AA to MG, NH(4

Peroxynitrite is shown here to promote the aerobic oxidation of isobutanal (IBAL) and 3-methyl-2,4-pentanedione (MP) in a pH 7.2 phosphate buffer into acetone plus formate and biacetyl plus acetate, respectively. These products are expected from diox

In the presence of the surfactant hexadecyltrimethyl ammonium bromide (CTAB) a cascade of electronically excited states accompanies the successive steps in the peroxidative metabolization of the strong estrogenic and tumourogenic diethylstilbestrol.

— When the synthetic estrogen and tumourogenic compound diethylstilbestrol is exposed to horseradish peroxidase (HRP) and H2O2 in the presence of the cationic surfactant hexadecyltrimethyl-ammonium bromide (CTAB), a burst of oxygen consumption and

The peroxidase-catalyzed aerobic oxidation of a linear aldehyde, leading to the next lower homologue in the triplet state, is accompanied by Norrish type II product ethylene when the substrate is pentanal. This system appears to provide an example of

The aerial parts of the species Mikania triangularis afforded one known and three new pimaradiene diterpenes besides friedelin and stigmasterol. Their structures were deduced on the basis of spectral data and chemical modifications.
