Alternatives To Nitroprusside, William T. Hiscock
Alternatives To Nitroprusside, William T. Hiscock
Honors Theses
Any transition metal nitrosyl complex may release nitric oxide and thus has potential as a vasodilator. Nitroprusside, Na2[Fe(CN)5(NO)], is currently used, but dosages are limited because of the potential release of cyanide. Research in our group has been directed towards the synthesis of iron and ruthenium complexes containing the nitrosyl ligand and polypyridyl coligands such as 2,2-dipyridyl (bpy) and 2,2': 6',2"-terpyridine (tpy). These coligands are much less toxic than cyanide. Both [(bpy)(tpy)Fe(NO)]3+ and [(bpy)(tpy)Ru(NO)]3+ have been synthesized and characterized using infrared and ultraviolet spectroscopy, conductivity, and magnetic susceptibility. Along with the search for other possible polydentate coligands, is the search …

Honors Theses
The drug sodium pentacyanonitrosylferrate(2-)dihydrate, more commonly known as nitroprusside or nipride (Fig. 1), is a common vasodilating agent given clinically to patients with hypertension.12.22 Nitroprusside is effective in emergency rooms as it quickly reduces high blood pressure, but dosages are limited because of fear that cyanide could be released also. Nitroprusside is effective because the vasodilating agent nitric oxide, NO, is released. Nitric oxide is also recognized as an important biochemical messenger molecule.22 Our research involves a search for different species that could introduce nitric oxide into the body without cyanide. Transition metal complexes involving ruthenium, iron, and cobalt that …
