Treatment of 1-(n-butyl)-3-N-(2-Ar)acetamido-1, 3-imidazolium chloride (Ar=furylmethyl,phenylmethyl) with excess K2CO3 and [PdCl2(L−L)] (L−L=2 PPh3, dppf) afforded orange compounds composition [(1-(n-butyl)-3-N-(2-Ar)acetamido-1,3-imidazol-2-ylidene)]2Pd (Ar=furylmethyl; phenylmethyl). These complexes were characterized by NMR (1H 13C{1H} NMR), IR micro-analysis data. Subsequently, the catalyti...

n-Butyl Alcohol is a primary aliphatic alcohol historically used as a solvent in nail care cosmetic products, but new concentration of use data indicate that it also is being used at low concentrations in eye makeup, personal hygiene, and shaving cosmetic products. n-Butyl Alcohol has been generally recognized as safe for use as a flavoring substance in food and appears on the 1982 Food and Dru...

BACKGROUND Accumulating evidence suggests that the ubiquitous anion nitrite (NO2-) is a physiological signaling molecule, with roles in intravascular endocrine nitric oxide transport, hypoxic vasodilation, signaling, and cytoprotection. Thus, nitrite could enhance the efficacy of reperfusion therapy for acute myocardial infarction. The specific aims of this study were (1) to assess the efficacy...

In the past [1-3], most frequently used model substrates for the peroxyester reaction included, among others, hydrocarbons containing activated hydrogen atoms, such as, cyclohexene, and ethers, such as, tetrahydrofuran. Peroxyamidate 1 (R = N(CH3)2) of acceptable purity was prepared in molar quantities by an improvement of the procedure reported by Pedersen [4] utilizing the reaction of N,N-dim...

Nitrite is a storage reservoir of nitric oxide that is readily reduced to nitric oxide under pathological conditions. Previous studies have demonstrated that nitrite levels are significantly reduced in cardiovascular disease states, including peripheral vascular disease. We investigated the cytoprotective and proangiogenic actions of a novel, sustained-release formulation of nitrite (SR-nitrite...

INTRODUCTION Tissue reperfusion following hemorrhagic shock may paradoxically cause tissue injury and organ dysfunction by mitochondrial free radical expression. Both nitrite and carbon monoxide (CO) may protect from this reperfusion injury by limiting mitochondrial free radial production. We explored the effects of very small doses of inhaled nitrite and CO on tissue injury in a porcine model ...

The P atom in the title mol-ecule, C(10)H(23)ClN(3)O(2)P, has a distorted tetra-hedral coordination. In the C(O)NHP(O) unit, which has syn-oriented phosphoryl and N-H groups, the P-N bond of 1.703 (2) Å is longer and the O-P-N angle of 103.86 (7)° is contracted compared with the respective values in the two P(O)NHC(CH(3))(3) units [P-N = 1.632 (2) and 1.624 (2) Å; O-P-N = 116.80 (8) and 115.32 ...

Nitrite reductase (cytochrome c,d1) was purified from Pseudomonas aeruginosa. In the presence of the reducing system, ascorbate-N,N,N',N'-tetramethylphenyl-enediamine, which alone had no ability to reduce nitrite or NO at pH 7.5, the enzyme catalyzed the reduction of nitrite to NO and N2O as major and minor products, respectively, as determined by gas chromatography-mass spectrometry. The rate ...
