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.

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.

RECTAL ADMINISTRATION OF IODIDE AND PROPYLTHIOURACIL IN THE TREATMENT OF THYROID STORM

We administered potassium iodide and propylthiouracil per rectum, in conjunction with intravenous dexamethasone and propranolol, for emergent treatment of a patient in thyroid storm with small bowel obstruction, Shortly after initiation of this treatment, the patient successfully underwent two emergent surgical procedures for resection of an intestinal volvulus with advanced peritonitis, Serum levels of iodide and propylthiouracil showed substantial absorption of these drugs via the rectal route, Measurement of 24-h urinary-free iodide indicated that the bioavailability of potassium iodide delivered by retention enema was at least 40%, Parenteral iodide preparations have been unavailable in the past, and continue to be difficult to obtain emergently. Rectal administration of inorganic iodide is an effective, readily available and less expensive alternative to parenteral sodium iodide for patients in thyroid storm with upper gastrointestinal tract dysfunction.

Di(ethylxanthate) complex of cobalt(II) as neutral carrier for highly selective iodide electrode

A new solvent polymeric membrane electrode based on di(ethylxanthate) complex of Co(II) is described which demonstrates excellent selectivity toward the iodide ion.The resulting electrode exhibits fairly low detection limits and good selectivity properties.The selectivity sequence observed is iodide > thiocyanate > nitrite > bromide>perchlorate>sulfate>nitrate>chloride. The excellent selectivity for iodide is related to the unique interaction between the central Co(II) ion and iodide. The response mechanism of the electrode was also studied with the ac impedance and spectroscopic techniques.

In Vitro Bioavailability Study of an Antiviral Compound Enisamium Iodide

An investigation into the biopharmaceutics classification and a study of the in vitro bioavailability (permeability and solubility) of the antiviral compound enisamium iodide (4-(benzylcarbamoyl)-1-methylpyridinium iodide) were carried out. The solubility of enisamium iodide was determined in four different buffers. Apparent intestinal permeability (P-app) of enisamium iodide was assessed using human colon carcinoma (Caco-2) cells at three concentrations. The solubility of enisamium iodide in four buffer solutions from pH 1.2 to 7.5 is about 60 mg/mL at 25 degrees C, and ranges from 130 to 150 mg/mL at 37 degrees C, depending on the pH. Based on these results, enisamium iodide can be classified as highly soluble. Enisamium iodide demonstrated low permeability in Caco-2 experiments in all tested concentrations of 10-100 mu M with permeability coefficients between 0.2 x 10(-6) cm s(-1) and 0.3 x 10(-6) cm s(-1). These results indicate that enisamium iodide belongs to class III of the Biopharmaceutics Classification System (BCS) due to its high solubility and low permeability. The bioavailability of enisamium iodide needs to be confirmed in animal and human studies.

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.
