It is of interest that under certain conditions SOD can manifest both inhibitory and stimulatory effects on lipid peroxidation. Thus, Nelson et al. [37] showed that small SOD concentrations (up to 5 pg ml ) were protective in the reoxygenated isolated myocardium but very high doses (50 pg ml ) exacerbated the injury. These authors hypothesized that superoxide may not only initiate lipid peroxidation but also inhibited it, reacting with free radicals ... [Pg.776]

As mentioned earlier, when NO concentration exceeds that of superoxide, nitric oxide mostly exhibits an inhibitory effect on lipid peroxidation, reacting with lipid peroxyl radicals. These reactions are now well studied [42-44]. The simplest suggestion could be the participation of NO in termination reaction with peroxyl radicals. However, it was found that NO reacts with at least two radicals during inhibition of lipid peroxidation [50]. On these grounds it was proposed that LOONO, a product of the NO recombination with peroxyl radical LOO is rapidly decomposed to LO and N02 and the second NO reacts with LO to form nitroso ester of fatty acid (Reaction (7), Figure 25.1). Alkoxyl radical LO may be transformed into a nitro epoxy compound after rearrangement (Reaction (8)). In addition, LOONO may be hydrolyzed to form fatty acid hydroperoxide (Reaction (6)). Various nitrated lipids can also be formed in the reactions of peroxynitrite and other NO metabolites. [Pg.777]

A series of substituted diaryselenides were examined in three lipid peroxidation model systems isolated rat liver microsomes treated with Fe(II)/(ADP)/ascorbate and isolated rat hepatocytes treated with two different initiators of oxidation. In rat hepatocytes, all of the tellurides performed more effectively than the selenides. Particularly for the rat liver microsome system, the substituent effects on lipid peroxidation were consistent with what would be expected Electron-donating groups give more active compounds, while electron-withdrawing groups give poorer antioxidants. The same trends were seen for substituted diaryItellurides in inhibition of linoleic acid peroxidation in a two-phase model, where the dimethylamino... [Pg.139]

In rat hepatocytes, the compound curcumin was cyto-protective at concentrations of 0.05 mM, whereas at 5 mM the observed protective effect on lipid peroxidation was accompanied with a tendency to increase cellular glutathione depletion and lactate dehydrogenase leakage (Donatus et al. 1990). [Pg.292]

The incorporation of LA and CLA isomers into cellular phospholipids has different effects on lipid peroxidation measured as oxygen consumption (Fig. 10.8—10.11). PC(SA LA) at a level of 5 mol% of total fatty acids reduced oxygen consumption in all of the tested PC liposome systems (Fig. 10.8—10.11), while 5 mol% PC(SA c9,rl 1-CLA) increased oxygen consumption in liposomes prepared with PC(soy) and PC(egg yolk), but reduced it in PC(rat heart) and PC(rat brain) liposomes. These data indicated that PC(SA cS,tl 1-CLA) may exhibit antioxidant or pro-oxidant properties in different phospholipids systems including membranes. Interestingly, PC(SA rlO,differed from both PC(SA LA) and PC(SA c9,t 1-CLA) in its influence on lipid peroxidation in liposome prepared with different PC. Incorporation of 5 mol% PC(SA rlO,cl2-CLA) decreased lipid oxidation in the soy PC liposomes (Fig. 10.8), but increased lipid oxidation in the liposomes prepared from all the other PC, egg, rat heart, and rat brain (Fig. 10.9—10.11). [Pg.144]

MRF A is an antioxidant and a potent inhibitor of lipid peroxidation [66-68]. MRF A showed inhibitory activity on NADPH-dependent lipid peroxidation (1C50 = 2.8 mcM) in rat hver microsomes, being 30 times and 70 times stronger than alpha-tocopherol (1C50 = 87 mcM) and ascorbic acid (1C50 = 200 mcM), respectively. Indole (1C50 = 330 mcM) and tryptamine (1C50 = 260 mcM), the partial stmctures of MRF A, had much weaker effects on lipid peroxidation [67]... [Pg.1212]
