Nitrous Oxide Release

Ni(ii) complex of bis-(2-ethyl-4-methylimidazol-5-yl)methane in methanol undergoes reductive nitrosylation in presence of NO to afford the corresponding Ni(i)-nitrosyl intermediate. Subsequent reaction with additional NO releases N2O with Ni(ii)-nitrito complex formation.

Reductive Nitrosylation

Studies in this laboratory have been concerned with mapping the chemical properties and mechanisms of NO interactions with hemes and other metal centers. These are models relevant to the mammalian biology of nitric oxide, an important bioregulatory molecule. Presented here will be an overview of flash photolysis kinetics investigations of ferri- and ferro-heme nitrosyl formation in model complexes and several heme proteins. Also described will be ongoing studies of reductive nitrosylation mechanisms involving the reactions of NO with water-soluble Fe(III) porphyrins and ferri-heme proteins and of several Cu(II) model complexes.

Reductive Nitrosylation

NO reactivity of three Co(ii) complexes, 1, 2 and 3 have been studied in degassed methanol solution. The complexes differ from each other in terms of denticity and flexibility of the ligand fameworks. Complex 1 undergoes reductive nitrosylation of the metal ion; 2 results in corresponding [CoIII(NO−)] complex; whereas 3 does not react with NO.

Endothelial Nitric Oxide

Nitric oxide (NO) is a potent endothelium-derived relaxing factor which also may modulate cardiomyocyte inotropism and growth via increasing cGMP. While endothelial nitric oxide synthase (eNOS) isoforms have been detected in non-human mammalian tissues, expression and localization of eNOS in the normal and failing human myocardium are poorly defined. Therefore, the present study was designed to investigate eNOS in human cardiac tissues in the presence and absence of congestive heart failure (CHF).Normal and failing atrial tissue were obtained from six cardiac donors and six end-stage heart failure patients undergoing primary cardiac transplantation. ENOS protein expression and localization was investigated utilizing Western blot analysis and immunohistochemical staining with the polyclonal rabbit antibody to eNOS (Transduction Laboratories, Lexington, Kentucky).
