Abstract:
The discoveries that nitric oxide (a.k.a. nitrogen monoxide) serves important roles in mammalian bioregulation and immunology have stimulated intense interest in the chemistry and biochemistry of NO and derivatives such as metal nitrosyl complexes. Also of interest are strategies to deliver NO to biological targets on demand. One such strategy would be to employ a precursor which displays relatively low thermal reactivity but is photochemically active to release NO. This proposition led us to investigate laser flash and continuous photolysis kinetics of nitrosyl complexes such as the Roussin's

Abstract:
Mixed ruthenium(II) nitrosyls have been synthesized in yields larger than 60% by a general reaction of [Ru(η5-C5H5)(PPh3)L]+X− (L = 2,2′-bipyridine or 1,10-phenanthroline, X = Cl or Br) or [Ru(η5-C5,H5)(PPh3)(L)X] (L = PPh3, pyridine, 3-picoline, 4-picoline, [Formula: see text], or [Formula: see text]; X− = Cl−, Br−, I−, CN−, NCS−, H−, or SnCl3−) with NOBr3 and N2O3. In these complexes NO seems to bind with the metal ion as NO+. The reactions of N2O3 gave either nitrito or nitrosyl dinitrito complexes. The reactions of NOBr3 with trichlorostannate complexes did not yield nitrosyl complexes, in

AbstractThe useful aspects of nitric oxide (NO) are nowadays widely known. Due to the need for this molecule in the maintenance of homeostasis, NO-releasing compounds are tested every year to optimize its levels in a patient suffering from low NO production. This manuscript is an update of some important historical concerns about nitrosyl complexes having the ability to act as NO-releasing compounds under the influence of different chemically modified environments. At present, the search for efficient and less harmful NO-releasing molecules at desirable targets and concentrations has gained co

Abstract:
Nitric oxide (NO) has been shown to both suppress and promote tumor growth, depending in part on concentration. Exogenous delivery of NO may lead to tumor suppression. Recent studies have proposed ruthenium nitrosyl complexes as catalytic donors of NO in reductive environments. Catalytic donation can provide a long-term, elevated NO flux compared to single use donors. Site-specific delivery is desirable to reduce systemic side effects, such as lowering of blood pressure. Three new ruthenium nitrosyl complexes were synthesized to impart site-specificity through amide coupling to polymers, si
