Abstract:

Reaction of CpMo(NO)(CH2Ph)Cl with Me2Mg, Ph2Mg, or PhCCLi reagents in THF affords the corresponding alkyl, aryl, or alkynyl CpMo(NO)(CH2Ph)R (R = hydrocarbyl) complexes as orange powders in good yields. Unlike related 16-electron CpMo(NO)R2 complexes, these 18-electron species exhibit good thermal stability due to their η2-benzyl-Mo interactions. Treatment of CpMo(NO)(CH2Ph)Cl with Na(DME)Cp provides dark green Cp2Mo(NO)(CH2Ph), whose solid-state molecular structure has been established by a single-crystal X-ray crystallographic analysis. The two Cp rings display different binding modes to th

Abstract:

The role of platelet-activating factor (PAF) and nitric oxide (NO) as mediators of the effects of tumor necrosis factor-α (TNF-α) on skeletal muscle contractility was studied in guinea pig extensor digitorum longus (EDL) muscle. TNF-α (5–10 ng/ml) reduced contractility at every stimulation frequency (1–200 Hz) and shifted the force-frequency relationship to the right. The role of NO and PAF as mediators of TNF-α was suggested by the protective effect of N G-nitro-l-arginine methyl ester (l-NAME; 1 mM), but not of N G-nitro-d-arginine methyl ester (d-NAME; 1 mM), and by the inhibitory effect of

Abstract:

Isolated hepatocytes incubated in the presence of the NO donors S-nitroso-N-acetylpenicillamine (SNAP) and 3-morpholino-sydnonimine (SIN-1) displayed a time- and dose-dependent inhibition of glucose synthesis from lactate plus pyruvate as the substrate which correlated with NO production, but not nitrite production. Neither the parent compound of SNAP, N-acetyl-DL-penicillamine (NAP), nor nitrite or nitrate had any significant effect on glucose output, indicating that the inhibition was due to the generation of NO within the incubation medium. The concentrations of NO required for this effect

Abstract:

Iron-regulatory proteins (IRP1 and IRP2) are RNA-binding proteins that bind to stem-loop structures known as iron-responsive elements (IREs). IREs are located in the 5′- or 3′-untranslated regions (UTRs) of specific mRNAs that encode proteins involved in iron homeostasis. The binding of IRPs to 5′ IREs represses translation of the mRNA, whereas the binding of IRPs to 3′ IREs stabilizes the mRNA. IRP1 and IRP2 binding activities are regulated by intracellular iron levels. In addition, nitric oxide (NO.) increases the affinity of IRP1 for IREs. The role of NO. in the regulation of IRP1 and IRP2

Abstract:

The article is a review of the data on synthesis and physiological activity of hybrid antioxidants. The introduction offers an explanation to the fact why, in some cases, it is necessary to add drug molecules with fragments responsible for various properties and aimed at various targets. A large group of hybrid antioxidants comprise stable nitroxyl radicals that behave as antioxidants in free-radical reactions of oxidation. Compounds of this type were synthesized extensively to form a group of antitumor agents. As a rule, the specific (antitumor) activity retained or even increased as compared

The reaction of these radical compounds with nitric oxide and nitrogen dioxide was also investigated. The radicals synthesized, show selectivity in their reaction with these nitric oxides, depending on their structure (nitronyl-nitroxide radicals react with NO, while hydrazyl radicals react with NO2).

Abstract:

Functionalization of carbonyls, particularly with a heteroatom subunit, is an important synthetic transformation. Utilization of ambident electrophiles for such a strategy is advantageous because two different heteroatom units can be installed from a single source under judicial reaction conditions. Recently, there have been increased examples for the construction of C–O and C–N bonds using nitroso compounds, a prototype of ambident electrophiles. In this short review, we discuss the advantages and challenges of exploiting nitroso compounds in organic synthesis with specific focus on nitroso a

Recent studies have demonstrated that a nitroso compound derived from L-arginine (Arg) may be the endothelium-derived relaxing factor (EDRF) released from vascular endothelium. Synthesis of EDRF from L-Arg is inhibited by analogues of Arg such as NG-monomethyl-L-arginine (L-NMMA) and N omega-nitro-L-arginine (L-NNA). We tested the role of compounds derived from Arg in the constriction of the proximal left anterior descending coronary artery (LAD) to serotonin in vivo by measuring responses before and during infusion of L-NMMA or L-NNA.

In the solid state, the perchlorate counter ion is hydrogen bound to the ligated alcohol, as observed for [ReH(CH3OH)(CO)(NO)(PPh3)2]ClO4. This latter complex also results from the reaction of [ReH(CH3OH)(NO)(PPh3)3]ClO4 with CO under ambient conditions. On reaction with p-tolylisocyanide (RNC), however, substitution is also accompanied by dihydrogen elimination to give [Re(OR)(NO)(CNR)2(PPh3)2]ClO4, irrespective of the
