Several mechanisms regarding the adverse health effects of nanomaterials have been proposed. Among them, oxidative stress is considered to be one of the most important. Many in vitro studies have shown that nanoparticles generate reactive oxygen species, deplete endogenous antioxidants, alter mitochondrial function and produce oxidative damage in DNA. 8-Hydroxy-2'-deoxyguanosine is a major type...
INTRODUCTION AND OBJECTIVES Heart failure is associated with increased free radical production, which leads to a state of oxidative stress. Known markers of oxidative stress include 8-hydroxy-2'-deoxyguanosine, which reflects oxidative damage to DNA, and lipid peroxidation, which can be used to quantify damage to lipid-rich structures. The aims of this study were to compare 8-hydroxy-2'-deoxygu...
Straightforward conversion of (+)-6,8-dimethoxy-3,4-dihydro-3- undecylisocoumarin (3) to the title isocoumarin was carried out. Hydrolytic ring opening of (3) afforded the hydroxy acid (4) which was immediately oxidized to keto acid (5) using chromic acid, Cyclodehydration of (5) afforded the 6,8- dimethoxy-3-undecylisocoumarin (6) which on selective demethylation of 8- methoxy group furni...
