Electrochemically triggered iodide-vacancy BiOI film for selective extraction of iodide ion from aqueous solutions

The effective extraction and regeneration of radioactive iodide remains an urgent concern for safe nuclear energy utilization. Herein, we developed a novel electrochemically triggered iodide-vacancy BiOI film, which exhibited excellent I- ion extraction capacity of 328.3 mg.g(-1). Especially, due to the ion vacancy trap effect, the film showed high selectivity towards I- ions in the existence of a large number of competitive anions. Additionally, the electrochemically switched ion extraction (ESIE) process with this iodide-vacancy BiOI film possessed fast extraction kinetics and high stability. More importantly, the trapped I(- )ions were easily desorbed from the film without the secondary pollution during the ESIE process and meanwhile, the iodide-vacancy BiOI film was able to be completely regenerated. It is expected that such an iodide-vacancy BiO film with ESIE could become a promising process for the selective extraction of I- ions from the radioactive water.

Acyl iodides in organic synthesis: XIII. Reaction of acyl iodides with nitrogen-containing heteroaromatic compounds

Reactions of acetyl iodide with pyridine at room temperature and with quinoline both at 20-25A degrees C and on cooling to -50A degrees C involve dehydrohalogenation of acetyl iodide with formation of ketene and pyridinium or quinolinium iodides. The reaction of acetyl iodide with pyridine at -5 to -50A degrees C led to the formation of N-acetylpyridinium iodide. Benzoyl iodide reacted with both pyridine and quinoline at both -50A degrees C and at 20-25A degrees C to form stable N-benzoylpyridinium and N-benzoylquinolinium iodides. The reaction of pyrrole with acetyl iodide under analogous conditions was accompanied by polymerization.

Letter: Silver mediated ester bond formation in the gas phase: substrate structure is important

The silver acetate cation CH3CO2Ag2+ reacted with allyl iodide via C-O bond coupling to produce Ag2I+ and allyl acetate, but only underwent adduct formation with methyl iodide, highlighting the importance of substrate on reactivity. DFT calculations predicted the reaction with ally] iodide to be exothermic by 0.48eV and suggested that intermediates in the reaction benefit from multiple interactions between the allyl and iodide moieties of allyl iodide and the two silver atoms in CH3CO2Ag2+.

Diamond paste based electrodes for the determination of iodide in vitamins and table salt

A new class of monocrystalline diamond paste based electrodes is proposed for the determination of iodide. Natural diamond and synthetic diamonds were used for the electrodes’ construction. The detection limits were very low. Bromide and chloride did not interfere in the determination of iodide. The proposed method is very reliable for the determination of iodide at very low concentration levels in vitamins and table salt (RSD < 1%). Interested yet?

IODIDE MUMPS AFTER INTRAVASCULAR ADMINISTRATION OF A NONIONIC CONTRAST-MEDIUM – CASE-REPORT AND REVIEW OF THE LITERATURE

Swelling of the submandibular, sublingual and/or parotid glands (”iodide mumps”) is an uncommon complication to intravascular administration of contrast material. The etiology remains unclear, but the reaction seems to be idiosyncratic or related to toxic accumulation of iodide in the ductal systems of the salivary glands. The introduction of nonionic contrast media has not eliminated the risk of developing iodide mumps. The first reported case of iodide mumps after intravascular administration of iopromide (Ultravist 300) is presented.

EXAMINATION OF ANTITHYROID EFFECTS OF SMOKING PRODUCTS IN CULTURED THYROID-FOLLICLES – ONLY THIOCYANATE IS A POTENT ANTITHYROID AGENT

We studied the antithyroid action of cigarette smoking products (nicotine, cotinine, and thiocyanate) in the physiological culture system of porcine thyroid follicles. Iodide uptake, iodine organification, de novo thyroid hormone formation, and iodide efflux were measured in the presence of 0-200 mumol/l nicotine, cotinine, or potassium thiocyanate. Nicotine and cotinine did not inhibit iodide transport or thyroid hormone formation. Thiocyanate concentrations equivalent to serum levels of smokers showed three independent antithyroid actions: (i) inhibition of iodide transport, (ii) inhibition of iodine organification, and (iii) increased iodide efflux. Inhibition of iodide transport by thiocyanate was competitive with iodide and independent of TSH concentration. Thiocyanate did not inhibit TSH mediated cAMP production or Na+K+ATPase activity, a sodium pump for iodide transport. When 50 mumol/l thiocyanate was added 2 h after incubation with iodide or when 1 mumol/l thiocyanate was added from the beginning of incubation, iodine organification was inhibited without changing iodide transport. De novo thyroid hormone formation was clearly inhibited by 50 mumol/l thiocyanate. Thiocyanate increased iodide efflux although the degrees of iodide efflux by 10 mumol/l and 100 mumol/l thiocyanate did not differ significantly. In summary, thiocyanate, a product of smoking, has three independent antithyroid activities. The data of iodide transport kinetics suggest that thiocyanate can be an antithyroid agent particularly in iodine deficiency.

Differential regulation of the human sodium/iodide symporter gene promoter in papillary thyroid carcinoma cell lines and normal thyroid cells

The absence of TSH-stimulated radioiodide uptake in differentiated thyroid cancer is associated with a high recurrence rate and reduced survival. We studied regulation of the sodium/iodide symporter gene in human papillary thyroid cancer cell lines (BHP) and primary human thyroid cells. BHP cells expressed very low levels of sodium/iodide symporter mRNA and did not concentrate iodide, but iodide uptake was restored to levels seen in FRTL-5 rat thyroid cells by stable transfection of a sodium/iodide symporter cDNA. Sodium/iodide symporter gene expression, therefore, was necessary and sufficient for iodide uptake in BHP cells. We cloned the human sodium/iodide symporter gene 5′-flanking region and analyzed progressive 5′-deletions in transient transfections. We identified a region, -596 to -268, essential to confer full promoter activity in primary normal human thyroid cells. Sodium/iodide symporter promoter activity in four BHP cell lines, however, was markedly reduced, consistent with downregulation of the endogenous sodium/iodide symporter gene. Nuclear extracts from BHP 2-7 cells had reduced or absent binding to regions of the sodium/iodide symporter promoter shown to be critical for expression, compared with nuclear extracts from FRTL-5 cells. Competition studies indicated that these nuclear proteins were not known thyroid transcription factors. Modifications of the sodium/iodide symporter promoter with demethylation or histone acetylation did not increase sodium/iodide symporter expression, and no deletions of the critical regulatory region were identified in the endogenous gene in BHP cells. Regulation of the sodium/iodide symporter 5′-flanking region in transient transfection paralleled endogenous sodium/iodide symporter expression. Reduced expression of potential novel nuclear factor(s) in these cell lines may contribute to reduced sodium/iodide symporter expression resulting in absence of iodide uptake in some papillary thyroid cancers.

Acid-mediated halogen exchange in heterocyclic arenes: A highly effective iodination method

Heterocyclic arenes including pyridyl, quinolyl and isoquinolyl chlorides have been converted to their corresponding iodides in good to high yields via acid-mediated nucleophilic halogen exchange with sodium iodide. This procedure avoids the use of transition metals, harsh reaction conditions, and affords highly regioselective halide exchange. Chloride substituents in position 2 and 4 of pyridines and quinolines are readily substituted by iodide in 75-91% and conversion of 1-chloroisoquinoline to its iodide derivative was found to proceed with 90% yield. Positions that are not activated for nucleophilic aromatic substitution proved to be inert to halide exchange. Regioselective chloride/iodide exchange in 4,7-dichloroquinoline hydrochloride gave 7-chloro-4-iodoquinoline, an important precursor of anti-malaria drugs, in almost 90% yield.
