Antiatherogenic effects of the antioxidant BO-653 in three different animal models.

چکیده
Antioxidants have been proposed to have antiatherogenic potential by their inhibition of low density lipoprotein (LDL) oxidation. Here, we report an antioxidant, BO-653 (2,3-dihydro-5-hydroxy-2, 2-dipentyl-4,6-di-tert-butylbenzofuran), designed to exhibit antioxidative potency comparable to that of alpha-tocopherol, but yet possess a high degree of lipophilicity comparable to that of probucol. BO-653 exhibits a high affinity for LDL and is well distributed in aortic vessels in vivo. In atherosclerosis models of rabbits and mice, BO-653 has been shown to be able to suppress the formation of atherosclerotic lesions without untoward side effects. Specifically, there was no reduction of high density lipoprotein levels. This antioxidant provides additional evidence in support of the oxidized-LDL hypothesis, and itself is a promising candidate antioxidant for clinical use.

This study was conducted to investigate the effect of supplementation different levels of pomegranate seed pulp (PSP) on performance and blood parameters in laying hens. A total of 96 layers hens (Hy-line W-36) at 24 week of age were randomly assigned into 4 treatments including 0 (control), 5, 10 and 15% of PSP, with 4 replicates containing 6 layers in each. Results showed no significant effec...
متن کاملEffect of probucol on LDL oxidation and atherosclerosis in LDL receptor-deficient mice.
Probucol is a powerful inhibitor of atherosclerosis in a number of animal models. However, it is unknown whether this is due to the strong antioxidant protection of low density lipoprotein (LDL), to antioxidant effects in the artery wall, or to cellular effects not shared by other antioxidants. To investigate whether murine models are suitable to study the antiatherogenic mechanisms of probucol...
