Iodide Binding in Sodium-Coupled Cotransporters

Several apical iodide translocation pathways have been proposed for iodide efflux out of thyroid follicular cells, including a pathway mediated by the sodium-coupled monocarboxylate transporter 1 (SMCT1), which remains controversial. Herein, we evaluate structural and functional similarities between SMCT1 and the well-studied sodium-iodide symporter (NIS) that mediates the first step of iodide entry into the thyroid. Free-energy calculations using a force field with electronic polarizability verify the presence of a conserved iodide-binding pocket between the TM2, TM3, and TM7 segments in hNIS, where iodide is coordinated by Phe67, Gln72, Cys91, and Gln94. We demonstrate the mutation of residue Gly93 of hNIS to a larger amino acid expels the side chain of a critical tryptophan residue (Trp255) into the interior of the binding pocket, partially occluding the iodide binding site and reducing iodide affinity, which is consistent with previous reports associating mutation of this residue with iodide uptake deficiency and hypothyroidism. Furthermore, we find that the position of Trp255 in this hNIS mutant mirrors that of Trp253 in wild-type hSMCT1, where a threonine (Thr91) occupies the position homologous to that occupied by glycine in wild-type hNIS (Gly93). Correspondingly, mutation of Thr91 to glycine in hSMCT1 makes the pocket structure more like that of wild-type hNIS, increasing its iodide affinity. These results suggest that wild-type hSMCT1 in the inward-facing conformation may bind iodide only very weakly, which may have implications for its ability to transport iodide.

Synthesis of a Stable Primary-Alkyl-Substituted Selenenyl Iodide and Its Hydrolytic Conversion to the Corresponding Selenenic Acid

A primary-alkyl-substituted selenenyl iodide was successfully synthesized through oxidative iodination of a selenol with N-iodosuccinimide by taking advantage of a cavity-shaped steric protection group. The selenenyl iodide exhibited high thermal stability and remained unchanged upon heating at 100 degrees C for 3 h in [D-8]toluene. The selenenyl iodide was reduced to the corresponding selenol by treatment with dithiothreitol. Hydrolysis of the selenenyl iodide under alkaline conditions afforded the corresponding selenenic acid almost quantitatively, corroborating the chemical validity of the recent proposal that hydrolysis of a selenenyl iodide to a selenenic acid is potentially involved in the catalytic mechanism of an iodothyronine deiodinase.

Iodide transport and breast cancer

Breast cancer is the second most common cancer worldwide and the leading cause of cancer death in women, with incidence rates that continue to rise. The heterogeneity of the disease makes breast cancer exceptionally difficult to treat, particularly for those patients with triple-negative disease. To address the therapeutic complexity of these tumours, new strategies for diagnosis and treatment are urgently required. The ability of lactating and malignant breast cells to uptake and transport iodide has led to the hypothesis that radioiodide therapy could be a potentially viable treatment for many breast cancer patients. Understanding how iodide is transported, and the factors regulating the expression and function of the proteins responsible for iodide transport, is critical for translating this hypothesis into reality. This review covers the three known iodide transporters – the sodium iodide symporter, pendrin and the sodium-coupled monocarboxylate transporter – and their role in iodide transport in breast cells, along with efforts to manipulate them to increase the potential for radioiodide therapy as a treatment for breast cancer.

Gene therapy with sodium/iodide symporter in hepatocarcinoma

The ability of thyroid cells to accumulate iodide is a prerequisite for successfull radioiodide therapy of benign thyroid diseases and differentiated thyroid carcinoma. The transport of iodide across the cell membrane is mediated by the sodium iodide symporter (hNIS). Employing a bicistronic retroviral vector for the transfer of the hNIS coding sequence and the hygromycin resistence gene stable hNIS expressing rat Morris hepatoma (MH3924A) cell lines were generated by hygromycin selection. Genetically modified MH3924A cell lines accumulated up to 235 times more iodide when compared to non-infected hepatoma cells with a maximal iodide uptake after 60 minutes incubation. Competition experiments in the presence of sodium perchlorate revealed a dose dependent decrease of the iodide uptake, FCCP led to a loss of accumulated I-, whereas DIDS increased the I- uptake into the cells. However, a rapid efflux of the radioactivity (80%) was observed during the first 10 minutes after the I-125(-) containing medium had been replaced by non-radioactive medium. In rats, the hNIS-expressing tumors accumulated six times more iodide as compared to the contralateral wild type tumor as monitored by scintigraphy. An ex vivo quantitation of the iodide content performed 1 hour after tracer administration in Ig tumor tissue revealed a 17-fold higher iodide accumulation in the genetically modified tumors. In vivo also a rapid efflux of the radioactivity out of the tumor was observed. Therefore, the transduction of the hNIS gene per se is sufficient to induce I-125(-) transport in Morris hepatoma cells in vitro and in vivo. For a therapeutic application of the hNIS gene, however, additional conditions need to be defined which inhibit the iodide efflux.

Selective sorption of iodide onto organo-MnO2 film and its electrochemical desorption and detection

This paper reports an electrochemically grown film consisting of layered MnO2 intercalated with hexadecylpyridinium cations (HDPy+), which can selectively sorb and detect iodide anions in aqueous solution amperometrically. Sorption of iodide by the HDPy/MnO2 film did not occur via ion exchange, but through hydrophobic interactions between the interlayer organic phase of the film and iodide ions in solution. The sorption rate increased with the deposited amount of MnO2. During the sorption process, the interlayer spaces expanded, and new diffraction peaks appeared that were attributed to the incorporated species. Anodic polarization of the iodide-sorbed HDPy/MnO2 film led to electron transfer from the incorporated iodide to the underlying substrate through the MnO2 sheets. The oxidized iodide was expelled from the film as molecular I-2, while the expanded interlayer spaces were restored to their original state. Thus, the MnO2 layers and the incorporated HDPy can synergistically sorb/desorb iodide anions, resulting in a unique self-cleaning function that can operate electrochemically. This property allowed amperometric detection of iodide at a concentration as low as 0.0186 mM, which was below the detection limits reported for previous iodide sensors. (C) 2015 Elsevier B.V.

Nanoparticles for nucleation of heavy metal iodide films: mercuric iodide and bismuth tri-iodide cases

Mercuric iodide and bismuth tri-iodide nanoparticles were synthesized by suspension in octadecene, from Hg(NO3)(2)center dot H2O and I-2, and from Bi(NO3)(3)center dot 5H(2)O and I-2, respectively. The best synthesis conditions were 2 hrs. at 60-70 degrees C, followed by 10 min. at 95-110 degrees C for mercuric iodide nanoparticles, and 4 hrs. at 80-110 degrees C, followed by 10 min. at 180-210 degrees C for bismuth tri-iodide ones. Nanoparticles were then washed and centrifugated with ether repeatedly. Compounds identity was confirmed by X-ray diffraction (XRD) and energy dispersive spectrometry (EDS). Nanoparticles were characterized by transmission (TEM) and scanning (SEM) electron microscopy. Disk-like and squared mercuric iodide nanostructures were obtained, 80-140 nm and 100-125 nm in size respectively. Rounded and rod-like bismuth tri-iodide nanoparticles, 30-500 nm in size were obtained. Acetonitrile and isopropanol suspensions of mercuric iodide nanoparticles, and acetonitrile suspension of bismuth tri-iodide nanoparticles exhibited peak maxima shifts in their UV-Vis spectra, as was reported for nanoparticles of other materials. It is the first time that mercuric iodide and bismuth tri-iodide nanoparticles are synthesized by the suspension method, although uniform shape and size distributions have not yet been obtained. They offer interesting perspectives for crystalline film nucleation, for improving current applications of these materials, as far as for opening new ones.

O-glycoside synthesis with glycosyl iodides under neutral conditions in 1 M LiClO4 in CH2Cl2

Glycosyl phosphates, imidates, trifluoroacetates, chlorides, and bromides are converted into the respective glycosyl iodides by treatment with LiI or NaI in 1 M solutions of LiClO4 in CH2Cl2. Under these neutral conditions the reactive glycosyl iodides are activated, and react with different glycosyl acceptors to give O-glycosides in moderate yields, with the alpha-anomers predominating. The glycosylation reactions most probably proceed by the initial formation of beta-configured glycosyl iodides from the alpha-configured precursors, and subsequent attack of the glycosyl acceptor on the equatorial iodide from the axial direction.

An Efficient Gram Scale Synthesis of Aryl Iodides from Aryl Diazofluoroborates in Water Under Mild Conditions

Transition metal-free synthesis of synthetically valuable aryl iodides from aryl diazofluroborates in water under mild conditions has been described. Majority of synthesized aryl iodides are obtained in quantitative yields (>99 %) under present reaction conditions. The structural effects due to the substituents present on aryl diazofluoroborates did not show any satisfactory effect on the yields of the aryl iodides. Hence, the methodology presented here was found to be adventitious for the quantitative production of synthetically valuable aryl iodides.

Determination of free iodide in human serum: Separation from other I-species and quantification in serum pools and individual samples

A method for the determination of free iodide in human serum was developed. For this purpose iodide from pooled serum samples was separated from the organic manner by SEC. The iodide fraction subsequently was freeze-dried and analyzed by ion chromatography for quantification. Investigations for recovery and precision were carried out and were found to show sufficient results. For quality assurance ICP-MS was taken additionally as an total I-detector [1], using native and iodide-spiked serum samples. The iodide results of ICP-MS as well as those of IC were well corresponding. Iodine containing SEC-fractions from iodide-spiked samples showed no increased I-values except that in the iodide fractions, proving that there was no iodide conversion into other I-species (and vice versa) during the whole procedure. Free iodide from two serum pools of different healthy persons was determined as 2.25 and 2.43 mu g I-/L, respectively. The values are related to total iodine levels determined by ICP-MS. For comparative reasons a table of individual iodine and iodide values is presented.
