Vascular peroxynitrite formation during organic nitrate tolerance.
Nitroglycerin (NTG) is an important cardiovascular agent, but tolerance during continuous administration limits its clinical utility. Increased vascular superoxide production may mediate nitrate tolerance via a reduction in nitric oxide availability. Because superoxide anion and nitric oxide react avidly to form peroxynitrite, an aggressive cellular toxicant that nitrates protein tyrosine resid...
متن کاملBioactivation of organic nitrates and the mechanism of nitrate tolerance.
Organic nitrates, such as nitroglycerin, are commonly used in the therapy of cardiovascular disease. Long-term therapy with these drugs, however, results in the rapid development of nitrate tolerance, limiting their hemodynamic and anti-ischemic efficacy. In addition, nitrate tolerance is associated with the expression of potentially deleterious modifications such as increased oxidative stress,...
متن کاملEccentric dosing of nitrates does not increase cardiac events in patients with healed myocardial infarction.
This study was performed to investigate the risk of cardiac events by eccentric or continuous dosing of nitrates in patients with healed myocardial infarction. A total of 573 patients with healed myocardial infarction were assigned to one of two groups: a nitrate-treatment (n =239) and a nontreatment (n =334) group. The nitrate-treatment group was further subdivided into a group receiving eccen...
متن کاملNitrate tolerance, oxidative stress, and mitochondrial function: another worrisome chapter on the effects of organic nitrates.
A shortcoming in the clinical use of organic nitrates is the development of tolerance. Recent data have suggested that the denitrification of organic nitrates is mediated by mitochondrial aldehyde dehydrogenase and that dysfunction of this enzyme is an important cause of tolerance. In this issue of the JCI, evidence in support of this hypothesis is presented in an in vivo model of nitrate toler...
متن کاملthe effect of e-64 on the developmental competence of sheep cocs during in vitro maturation
in the present study, the effect of e-64 at different concentrations (0.5, 1, 5 and 10 µm) added to (1) the ivm medium on oocyte nuclear maturation and developmental competence of ovine oocytes, and (2) to the ivc medium on embryonic development of ovine embryos were investigated.
