Barbier-type reactions of nitriles and alkyl iodides mediated by samarium(II) iodide in the presence of catalytic nickel(II) iodide

The samarium(II) iodide-mediated intermolecular Barbier-type reactions of nitriles and alkyl iodides have been investigated. In the presence of a catalytic amount of nickel(II) iodide, the reaction proceeded smoothly to provide the corresponding ketones. Amides also reacted to give ketones under the same Barbier-type conditions. (C) 2000 Elsevier Science Ltd. All rights reserved.

Effect of iodide additives on the polymerization of 2,6-dimethylphenol with copper bromide n-butylamine catalyst

The effects of three iodide additives on the performances of two 2,6-dimethylphenol polymerization catalysts based on copper bromide were studied. The iodide additives were sodium iodide, potassium iodide and methyl iodide. The polymerization catalysts were CuBr2/n-butylamine and Cu2O/HBr/n-butylamine. Iodide addition resulted in the higher polymer molecular weight which decreased in the following order: NaI > KI > CH3I. Polymerization induction period increased significantly with NaI addition, but was insensitive to the concentrations of KI and CH3I. Addition of quaternary ammonium salt to the NaI-added catalyst dramatically shortened the induction period and greatly decreased the amount of copper catalyst needed. UV-VIS absorption spectroscopy showed that the Br–>I exchange occurred with the addition of NaI into the copper bromide-based catalyst. Besides, I–>Cl exchange was observed with the addition of methyltrioctylammonium chloride to the NaI-added catalyst. The I–>Cl exchange was caused by the binding of the iodide anion to the quaternary ammonium cation. Copper chloride/n-butylamine complex was generated after the I–>Cl exchange.

Inhibition of intrathyroidal dehalogenation by iodide

Iodide is a trace element and a key component of thyroid hormones (TH). The availability of this halogen is the rate-limiting step for TH synthesis; therefore, thyroidal iodide uptake and recycling during TH synthesis are of major importance in maintaining an adequate supply. In the rat, the thyroid gland co-expresses a distinctive pair of intrathyroidal deiodinating enzymes: the thyroid iodotyrosine dehalogenase (tDh) and the iodothyronine deiodinase type 1 (ID1). In the present work, we studied the activity of these two dehalogenases in conditions of hypo-and hyperthyroidism as well as during acute and chronic iodide administration in both intact and hypophysectomized (HPX) rats. In order to confirm our observations, we also measured the mRNA levels for both dehalogenases and for the sodium/iodide symporter, the protein responsible for thyroidal iodide uptake. Our results show that triiodothyronine differentially regulates tDh and ID1 enzymatic activities, and that both acute and chronic iodide administration significantly decreases rat tDh and ID1 activities and mRNA levels. Conversely, both enzymatic activities increase when intrathyroidal iodide is pharmacologically depleted in TSH-replaced HPX rats. These results show a regulatory effect by iodide on the intrathyroidal dehalogenating enzymes and suggest that they contribute to the iodide-induced autoregulatory processes involved in the Wolff-Chaikoff effect.

Sequential Slot-Die Deposition of Perovskite Solar Cells Using Dimethylsulfoxide Lead Iodide Ink

This work demonstrates a sequential deposition of lead iodide followed by methylammonium iodide using the industrially compatible slot-die coating method that produces homogeneous pin-hole free films without the use of the highly toxic dimethylformamide. This is achieved through the careful selection and formulation of the solvent system and coating conditions for both the lead iodide layer and the methylammonium iodide coating. The solvent system choice is found to be critical to achieving good coating quality, conversion to the final perovskite and for the film morphology formed. A range of alcohols are assessed as solvent for methylammonium iodide formulations for use in slot-die coating. A dimethylsulfoxide solvent system for the lead iodide layer is shown which is significantly less toxic than the dimethylformamide solvent system commonly used for lead iodide deposition, which could find utility in high throughput manufacture of perovskite solar cells.

Expression of the human sodium/iodide symporter (hNIS) in xenotransplanted human thyroid carcinoma

The uptake of iodide in thyroid epithelial cells is mediated by the sodium/iodide symporter (NIS). The uptake of iodide is of vital importance for thyroid physiology and is a prerequisite for radioiodine therapy in thyroid cancer. Loss of iodide uptake due to diminished expression of the human NIS (hNIS) is frequently observed in metastasized thyroid cancer. So far, no animal model for the study of radioiodine therapy in thyroid cancer has been available. Strategies to restore iodide uptake in thyroid cancer include the exploration of hNIS gene transfer into hNIS defective thyroid cancer. We have performed a stable transfection of hNIS into the hNIS defective follicular thyroid carcinoma cell line FTC133. Stabily transfected colonies exhibited high uptake of (NaI)-I-125, which could be blocked completely with sodiumperchlorate. hNIS transfected FTC133 and non-transfected cell lines injected subcutaneously in nude mice formed tumors after 6 weeks. Iodide uptake in the hNIS transfected tumor was much higher than in non-transfected tumor, but a rapid release of radioactivity from the hNIS transfected tumor was observed. Further studies are necessary to investigate the role of hNIS in relation to other thyroid specific proteins in iodide metabolism in thyroid cancer.

A Rare Case of Iodide Mumps after Percutaneous Interventional Liver Transarterial Chemoembolization

Iodide-induced sialadenitis (iodide mumps) is a rare complication of iodide-containing contrast media administration. The phenomenon is, in fact, a form of aseptic sialadenitis and is characterized by acute swelling of the salivary glands. The cause of this condition is not yet entirely clear, but reports have been published in favor of iodine concentration in the salivary glands. In this article, we present the first ever case of iodide-induced sialadenitis reported in our country, which arose following a percutaneous transarterial liver chemoembolization procedure.

Formation of CH3I in a NaI and methyl alkyl ketone solution under gamma irradiation conditions

We investigated the effects of concentrations of NaI and methyl alkyl ketone on the formation of methyl iodide under gamma irradiation conditions. Without irradiation, the formation of methyl iodide does not occur. For the formation of methyl iodide, the solution pH should be brought to lower than 6 by radiolytic decomposition of ketones and air. At a pH below 6, the iodide was oxidized into iodine, allowing for the formation of CH3I from the reaction of iodine and the CH3 radical. When the concentrations of NaI and methyl alkyl ketone were similar, the concentration of methyl iodide was generally at its highest, and as the gamma dose increased, the concentration of methyl iodide increased.

Conserved charged amino acid residues in the extracellular region of sodium/iodide symporter are critical for iodide transport activity

Background: Sodium/iodide symporter (NIS) mediates the active transport and accumulation of iodide from the blood into the thyroid gland. His-226 located in the extracellular region of NIS has been demonstrated to be critical for iodide transport in our previous study. The conserved charged amino acid residues in the extracellular region of NIS were therefore characterized in this study. Methods: Fourteen charged residues (Arg-9, Glu-79, Arg-82, Lys-86, Asp-163, His-226, Arg-228, Asp-233, Asp-237, Arg-239, Arg-241, Asp-311, Asp-322, and Asp-331) were replaced by alanine. Iodide uptake abilities of mutants were evaluated by steady-state and kinetic analysis. The three-dimensional comparative protein structure of NIS was further modeled using sodium/glucose transporter as the reference protein. Results: All the NIS mutants were expressed normally in the cells and targeted correctly to the plasma membrane. However, these mutants, except R9A, displayed severe defects on the iodide uptake. Further kinetic analysis revealed that mutations at conserved positively charged amino acid residues in the extracellular region of NIS led to decrease NIS-mediated iodide uptake activity by reducing the maximal rate of iodide transport, while mutations at conserved negatively charged residues led to decrease iodide transport by increasing dissociation between NIS mutants and iodide. Conclusions: This is the first report characterizing thoroughly the functional significance of conserved charged amino acid residues in the extracellular region of NIS. Our data suggested that conserved charged amino acid residues, except Arg-9, in the extracellular region of NIS were critical for iodide transport.
