Metabolism of monoepoxides of methyl linoleate: bioactivation and detoxification.
Leukotoxin (ltx) and isoleukotoxin (iltx) methyl esters, are metabolites of methyl linoleic acid, an essential fatty acid. They have been associated with acute respiratory distress syndrome. The observed toxicity of ltx and iltx is, in fact, due to the metabolism of the epoxides to their corresponding diols by soluble epoxide hydrolase (sEH). Herein, we demonstrate that ltx/iltx are toxic in a ...
متن کاملDepression of phagocytic activity of human polymorphonuclear leukocytes by methyl linoleate hydroperoxides.
Methyl linoleate hydroperoxides (MLHPO), a model for lipid hydroperoxides, decreased fungicidal activity of human polymorphonuclear leukocytes (PMN) for fungi of Candida albicans. When PMN was cultured with MLHPO, phagocytosis to fungi was depressed. Degree of the depression was dependent on the concentration of MLHPO and the treatment time with MLHPO. These findings indicate that phagocytic ac...
متن کاملDecomposition of linoleate hydroperoxides: precursors of oxidative dimers.
When hydroperoxides are thermally decomposed in the presence of unsaturated fatty acids, dimers are formed in amounts equivalent to the hydroperoxide present. The origin of these dimers has not been shown by any definitive experiment. Radioactively (14C) labeled materials now have been used to determine whether (1) two molecules of hydroperoxide react, (2) a hydroperoxide and an unoxidized fatt...
متن کاملLinoleate metabolism in multiple sclerosis.
(1) The levels of oleate and linoleate in the serum have been measured in 14 patients with multiple sclerosis (MS) and in 14 healthy subjects before, during and after a five day period when the normal diet was supplemented with linoleate. (2) In confirmation of earlier work the mean percentage of linoleate in the serum lipids of the MS patients was significantly lower (P < 0·01) than in the con...
متن کاملCharacterization by NMR of Ozonized Methyl Linoleate
No presente estudo o linoleato de metila ozonizado com índice de peróxidos de 1.800 mmol-equiv. kg foi caracterizado quimicamente. Os efeitos do ozônio sobre o linoleato de metila produz hidroperóxidos, ozonideos e aldeídos, os quais foram identificados por técnicas de ressonância magnética nuclear de H e C, monoe bidimensional. O linoleato de metila padrão e o linoleato de metila ozonizado mos...
