A convenient iodination method for alcohols using cesium iodide/methanesulfonic acid and its comparison using cesium iodide/p-toluenesulfonic acid or cesium iodide/aluminium chloride

In situ generation of hydrogen iodide from cesium iodide/methanesulfonic acid was found to be an attractive reagent combination for the conversion of alkyl, allyl, and benzyl alcohols to their corresponding iodides under mild conditions. The method is compared with that using cesium iodide/p-toluenesulfonic acid or cesium iodide/aluminium chloride.

Carbonyl allylations by allylic chlorides utilizing a reduction of tin(IV) iodide to triiodostannate(II) species with iodide sources

Carbonyl allylations by allylic chlorides either with tin(IV) iodide and tetrabutylammonium iodide (TBAI) in dichloromethane or with tin(IV) iodide and sodium iodide in 1,3-dimethylimidazolidin-2-one at room temperature produced the corresponding homoallylic alcohols. The carbonyl allylations probably proceeded via the reduction of tin(IV) iodide to triiodostannate(II) species with iodide sources such as TBAl and Nal, which led to the construction of a tin(IV)-catalytic cycle based on regeneration of tin(IV) iodide via the transmetalation of homoallyloxytriiodotin to homoallyloxytrimethylsilane with iodotrimethylsilane.

INHIBITION OF THYROCYTE IODIDE UPTAKE BY H(+)K(+)ATPASE INHIBITOR, TIMOPRAZOLE

The inhibitory effect of timoprazole on iodide uptake by cultured thyrocytes was observed using FRTL-5 cells. The inhibition was noticed to be dose dependent and was eliminated completely by rinsing. Timoprazole pretreated with acid had inhibitory effects, but [H-3] leucine incorporation experiments indicated that acidified timoprazole inhibited protein synthesis to some degree. In addition, TSH-induced cAMP production was also inhibited by acidified timoprazole. Timoprazole pretreated in a neutral solution did not have any cytotoxic effects on TSH-induced cAMP production or protein synthesis at concentrations less than 1000 mu M, suggesting that timoprazole by itself has specific effects on iodide uptake. The absence of any direct interaction of the drug with iodide was confirmed by separation of timoprazole and iodide on a C-18 Sep-Pak column. It is concluded that timoprazole by itself could inhibit iodide transport through the thyroid cell membrane. This may provide a useful system in further investigating the mechanism of iodide transport.

Copper-catalyzed etherification of aryl iodides using KF/Al2O3: An improved protocol

A simple and efficient method for the coupling of aryl iodides with aliphatic alcohols and phenols that does not require the use of alkoxide bases is described. This C-O bond forming procedure shows that the combination of air stable CuI and 1,10-phenanthroline in the presence of KF/Al2O3 comprises an extremely efficient and general catalyst system for the etherification of aryl iodides. Different functionalized aryl iodides were coupled with alcohols and phenols using this method.

Iodine assimilation by marine diatoms and other phytoplankton in nitrate-replete conditions

Several marine phytoplankton species, primarily diatoms, were examined for the accumulation of iodide (10 species) and iodate (9 species) using radioactive iodine-125 in f/2 artificial seawater, a nitrate-enriched medium. Iodide accumulation ( net uptake) rates were variable, and diatoms exhibited the highest rates. Emiliania huxleyi and Synechococcus sp. did not accumulate iodide. Accumulation rates ranged from 0 to 1.7 fmol cell(-1) d(-1). The diatom Porosira glacialis accumulated the greatest amount of iodide and was used to determine efflux rates of iodide. Iodide efflux was characterized by two distinct phases of iodide release: an initial rapid release rate of 10 amol cell(-1) min(-1) from the free space and a subsequent cellular release rate of 0.13 amol cell(-1) min(-1), which corresponds to a daily cellular release rate of 0.19 fmol cell(-1) d(-1). Accumulation of iodate ranged from 0 to 19 amol cell(-1) d(-1), with P. glacialis displaying the highest rate. Emiliania, Synechococcus, and Chaetoceros did not show significant iodate accumulation. Iodide is the preferred chemical species of iodine for uptake under nitrate-replete conditions: iodide accumulation rates ranged from 3 to 90 times larger than those for iodate for the species studied. If the iodate accumulated is tightly coupled to its reduction to iodide, the accumulation rates suggest that phytoplankton-mediated iodate reduction is not environmentally significant. If diatoms can reduce iodate to iodide, their overall contribution to surface-water iodide, while living, would be further reduced because of their ability to reassimilate released iodide.

MOLECULAR DYNAMICS SIMULATION OF A MOLTEN MIXTURE OF LITHIUM BROMIDE AND LITHIUM IODIDE

Molecular dynamics simulation for a 1:5 molar mixture of lithium bromide and lithium iodide was carried out with Born-Mayer-Huggins type pair potential. The self-exchange velocity of the iodide ion is greater than that of the bromide ion although the iodide ion is heavier than the bromide ion. This anion Chemla effect is explained from the difference in the barrier height of the potential function which the bromide ion or the iodide ion feels from the lithium ion. The pair distribution functions, the angular correlation functions and the velocity autocorrelation functions are also examined.

Mechanism of iodide/chloride exchange by pendrin

We performed an electrophysiological study to investigate ion transport of pendrin and thereby understand the pathogenesis of Pendred syndrome. Using pendrin-transfected COS-7 cells, we could show that pendrin transports both iodide and chloride measured as voltage-dependent inward and outward membrane currents. Chloride in the culture medium, [CI-](o), was efficiently exchanged with cytoplasmic iodide, [CI-](o), under physiological concentrations, indicating that pendrin is important for chloride uptake and iodide efflux. Although exchange of iodide in the medium, [I-](o), with cytoplasmic chloride, [Cl-](i), was observed, a significantly high concentration of iodide (10 mm) was required. In addition, either iodide or chloride was required on both sides of the cell membrane for the anion exchange activity of pendrin, indicating that iodide and chloride activate the exchange activity of pendrin while they are transported. The present study further supports that pendrin is responsible for the iodide efflux in thyroid cells where intracellular iodide concentration is high and that the general function of pendrin in other tissues is to transport chloride through exchange with other anions.
