Determination of nitrotyrosine with catalytic spectriophotometry combining the substitution of nitroxyl by iodide

The nitroxyl of nitrotyrosine can be substituted quantitatively by iodide when the nitroxyl is reduced to amino and then diazotized to diazonium. The iodide can be dertermined by catalytic spectrophotometric method with iodide-nitrous acid-arsenious acid system. Thus, a new catalytic spectrophotometric method combining the substitution of nitroxyl by iodide ford the determination of nitrotyrosine has been established. The limit of detection is 0.002 mumol.L-1 and the linear range is 0.005-0.25 mumol.L-1. The method has been used for the determination of nitrotyrosine in the-products of the reaction of tyrosine with peroxynitrite and the results are satisfactory.

Benzimidazole functionalized tripodal receptor for selective recognition of iodide

A novel tripodal fluorescent receptor with benzimidazole motifs as signaling unit is reported. The receptor can selectively bind iodide anion with drastic change in its fluorescence and UV/Vis spectra, while addition of other anions (F-, Cl-, Br-, H2PO4-, SO42-, CH3COO-, NO3- and CN-) does not show any significant change. The formation of receptor-iodide hydrogen bonded complex is proved by NMR titration of the receptor in the presence of iodide anion. (c) 2012 Elsevier Ltd. All rights reserved.

INVESTIGATION OF ION ADSORPTION ON SILVER SULFIDE, IODIDE AND BROMIDE PRECIPITATES BY THE RADIOACTIVE-TRACER TECHNIQUE

The radioactive tracer method was used to investigate the adsorption of iodide and europium ions from aqueous solution on dried isoelectric precipitates of silver sulfide, silver iodide and silver bromide. The relationship between the amount of iodide ions adsorbed on Ag2S and the iodide ion and HNO3 concentrations in the solution was determined. It was shown that the iodide ions adsorbed on Ag2S could be desorbed with sulfide ions. Using Ag2S, AgI and AgBr precipitates, a relationship between the europium ion adsorption and Eu(NO3)3, H2S, NaI, NaBr and NaCl concentration in solution was established. The adsorption of europium ions was also assessed in respect to the presence of lanthanum and barium ions. For adsorption measurement iodide and europium ions were labeled with their radioactive isotopes and the amounts adsorbed were determined from the measured radioactivities of the precipitates after reaching the equilibrium between the solid phase and the solution.

Iodide Effects on the Thyroid: Biochemical, Physiological, Pharmacological, and Clinical Effects of Iodide in the Thyroid

Iodide, the main and limiting substrate in the synthesis of thyroid hormones by the thyroid gland, also exerts physiological and pharmacological signaling effects on this organ. In vivo studies in humans and animals have demonstrated that at low or physiological levels (<0.4 mu M), iodide uptake limits the synthesis of thyroid hormones and therefore their secretion. These serum thyroid hormones depress the secretion of the main physiological activator of the gland, pituitary thyroid stimulating hormone (TSH). Thus, iodine deficiency leads to decreased thyroid hormone levels and compensatory TSH secretion. At these levels, there is an inverse relationship between iodide supply and TSH secretion. This is a negative indirect control. At high concentrations (0.4-10 mu M), iodide directly inhibits several activating thyroid signaling pathways. Such effects require an intact follicular structure and the oxidative organification of a postulate intermediate X to XI. Two iodinated lipids reproduce these effects of iodide: iodolactone and 2-iodohexadecanal. Only the latter is found in the thyroid. The direct effects of iodide and XI account for an inhibition of iodide oxidation itself, of iodide uptake, and of thyroid hormone secretion and thyroid growth. Besides the XI effects, iodide at very high pharmacological or toxicological concentrations (>10 mu M) appears to directly inhibit thyroid blood flow and secretion. The latter effects are used in the preoperative treatment of patients suffering from Graves’ disease with Lugol. The various experimental models used to elucidate the direct effects of iodide on the thyroid are discussed and analyzed. The chapter also describes the clinical consequences of the diverse iodide actions

Two Carbonylations of Methyl Iodide and Trimethylamine to Acetic acid and N,N-Dimethylacetamide by Rhodium(I) Complex: Stability of Rhodium(I) Complex under Anhydrous Condition

Rhodium(I)-complex [Rh(CO)(2)I-2(-)] (1) catalyzed two carbonylations of methyl iodide and trimethylamine in NMP (1-methyl-2-pyrolidone) to acetic acid and DMAC (N,N-dimethylacetamide) in the presence of calcium oxide and water. The carbonylation of trimethylamine continued during the carbonylation and consumption of methyl iodide. In total, 183.8 mmol of carbonylated products was produced while consuming 24.1 mmol methyl iodide via acetic acid formation. These results clearly indicated that there were two carbonylation routes of trimethylamine and methyl iodide and the carbonylation rate of trimethylamine was faster than that of methyl iodide. Rhodium(I)-complex [Rh(CO)(2)I-2](-) (1) in the presence of trimethylamine was stable enough to be used 25 times with TON (Turnover Number) of 368 for DMAC and TON of 728 for trimethylamine. Inner-sphere reductive elimination in stepwise procedure was suggested for the formation of DMAC instead of acyl iodide intermediate under anhydrous condition.

Effects of the Alkyl Chain Length of Imidazolium Iodide in the Electrolyte Solution on the Performance of Black-Dye-Based Dye-Sensitized Solar Cells

Five kinds of electrolyte solutions containing the imidazolium iodide with a different alkyl chain length (DMImI, EMImI, MPImI, DMPImI and HMImI; DMImI = 1,3-dimethylimidazolium iodide, EMImI = 1-ethyl-3- methylimidazolium iodide, MPImI = 1-methyl-3-n-propylimidazolium iodide, DMPImI = 1,2-dimethyl-3- n-propylimidazolium iodide, HMImI = 1-n-hexyl-3-methylimidazolium iodide) have been prepared to investigate the effects of the alkyl chain length of the imidazolium iodide on the performance of dyesensitized solar cells (DSCs) with Black dye and D131. The photocurrent density (Jsc) increased and the fill factor (FF) decreased with increasing the alkyl chain length of the imidazolium iodide. Electrochemical impedance spectroscopic measurements of the DSCs revealed that the conduction band energy of TiO2 shifted to the positive direction and the diffusion resistance of the redox couple in the electrolyte solution increased with increasing the alkyl chain length of the imidazolium iodide. Therefore, the observed increment of the Jsc value seems to be attributed mainly to the conduction band energy shift of TiO2, and the observed decrement of the FF value would be caused by increasing the diffusion resistance of the redox couple in the electrolyte solution. The conversion efficiency of the DSCs was found to depend on the ion conductivity of the electrolyte solution, which is closely related to the alkyl chain length of the imidazolium iodide. This study demonstrated that the conversion efficiency could be improved by using EMImI instead of the conventional imidazolium iodide (DMPImI) due to the larger ion conductivity with a slightly higher conduction band energy of TiO2.

Thermal effect in beta-selective glycosylation reactions using glycosyl iodides

The unique reactivity of glycosyl iodides and the fact that they react under neutral conditions makes them the donors of choice in our glycosylation strategies. Glycosyl iodides are generated in situ from either the anomeric acetate or the anomeric silylated derivative yielding the alpha-iodide. In the reported glycosylation reactions, protected glucosyl, galactosyl, and mannosyl iodides were reacted with trimethylene oxide as the acceptor, yielding the beta-anomer as the major product. In the absence of neighboring group participation, beta-selectivity is thought to arise from nucleophilic displacement of the alpha-iodide in an S(N)2-like mechanism, while the alpha-product is the result of nucleophilic attack on the beta-iodide. In this study, increased beta-selectivity using an inverse thermal effect is demonstrated. (c) 2005 Elsevier Ltd. All rights reserved.
