Reactions of a series of cobalt dinitrosyl/alkene addition products with conjugate acceptors in the presence of Sc[(OTf).sub.3]/LHMDS formed two new carbon-carbon bonds at the a-carbon positions on the nitrosyl groups of the substrate, leading to unusual tri-and tetracycles, retrocycloaddition of which in the presence of norbomadiene produced functionalized tetrasubstituted bicyclic alkenes.
We have previously evaluated Porphyrins in the context of photodynamic therapy (PDT) since they strongly absorb visible light in the blue region.14 In addition, we have also shown that these compounds serve as inhibitors for Acetylcholinesterase enzyme in erythrocytes and nerve tissue.15,16 This study was conducted to investigate the three Porphyrin derivatives: Tetraphenylporphinesulfonate (TPPS), 5,10,15,20-Tetrakis (4sulfonatophenyl) porphyrinato Iron(III) Chloride (FeTPPS) and 5,10,15,20-Tetrakis (4sulfonatophenyl) porphyrinato Iron(III) nitrosyl Chloride (FeNOTPPS), as candidate compounds for increasing the Na+, K+-ATPase activity in erythrocytes.
(2008) [H.sub.2]S and HS-donor NaHS releases nitric oxide from nitrosothiols, metal nitrosyl complex, brain homogenate and murine L1210 leukaemia cells.
The liquor was then added in portions during 30 min to a cold solution of nitrosyl sulphuric acid (prepared from sodium nitrite (0.15 g) and concentrated sulphuric acid (3 mL) at 50[degrees]C).
A final chapter looks at the oxidative ion-radical mechanisms in polymer interactions with diamagnetic nitrogen dioxide dimers in the form of nitrosyl nitrate.
NO is known to be released from nitrosyl hemoglobin or nitrosoglutathione by light irradiation (13).
It is stored as a nitrosyl ligand in an iron(II) complex to be released as necessary.
By absorbing the nitrogen oxide gas, the compound forms an iron nitrosyl complex that can be converted into ammonia, thus liberating the iron catalyst for further use.
After separation on a megabore capillary column, the N-nitrosamines are pyrolyzed at 500 [degrees] C to form nitrosyl radicals (equation 1); this temperature is too low (1) [Mathematical Expression Omitted] to pyrolize nitrosyl radicals from C-nitrosamines.
Compared to iron-based nitrosyl complexes, Ru nitrosyls are promising candidates as potential NO-donating agents for targeted delivery of NO to physiological targets due to their inherent stability and modest photosensitivity [16-21].
The EPR parameters of a set of Tc(II) nitrosyl complexes were reported in the previous studies in the literature [20].
