COUPLING REACTIONS OF CHLOROFLUORO AND PERFLUOROALKYL IODIDES

Coupling reactions of chlorofluoro- and perfluoroalkyl iodides R(f)-I with R(f) = ClCF(2)CFCl-(CF(2))(3)CF(2)-, ClCF(2)CFClO(CF(2))(3)CF(2)-, ClCF(2)CFCl-, (CF(3))(2)CF-, (CF(3))(2)CFCF(2)CF(2)- in the presence of a zinc/solvent system give dimers in good yields. Both homodimerizations (one iodide) and heterodimerizations (two different iodides) have been studied. The effect of temperature and solvent is shown. The zinc mediated dechlorination of vicinal chlorine atoms in the dimers afforded terminal alkenes and dienes.

Congenital goitrous hypothyroidism is caused by dysfunction of the iodide transporter SLC26A7

Iodide transport and storage in the thyroid follicles is crucial for thyroid hormone synthesis. Pendrin, the iodide exporter that transports iodide to thyroid follicles, is responsible for Pendred syndrome, a disorder characterized by congenital hypothyroidism and hearing loss. However, thyroid hormone levels are basically normal in patients with Pendred syndrome, indicating the presence of another unknown iodide transporter. Here, we show that SLC26A7 is a novel iodide transporter in the thyroid. We observe that SLC26A7 is specifically expressed in normal thyroid tissues and demonstrate its function in iodide transport. Using whole-exome sequencing, we also find a homozygous nonsense mutation in SLC26A7 (c.1498 C > T; p.Gln500Ter) in two siblings with congenital goitrous hypothyroidism. The mutated SLC26A7 protein shows an abnormal cytoplasmic localisation and lacks the iodide transport function. These results reveal that SLC26A7 functions as a novel iodide transporter in the thyroid and its dysfunction affects thyroid hormonogenesis in humans and causes congenital goitrous hypothyroidism.

Histidine residue at position 226 is critical for iodide uptake activity of human sodium/iodide symporter

The sodium/iodide symporter (SLC5A5; also known as NIS), a transamembrane glycoprotein principally in the thyroid gland, is responsible for the accumulation of iodide necessary for thyroid hormones. Our previous study indicated that a novel exon 6 deletion (residues 233-280) in SLC5A5 loses the iodide uptake activity. Herein we characterized the role of His-226 in iodide transport of SLC5A5. His-226, a highly conserved extracellular residue among SLC5A5 homologs, was replaced with alanine, aspartic acid, glutamic acid, or lysine. All the SLC5A5 mutants were expressed normally in the cells and targeted correctly to the plasma membrane. However, all of the mutants displayed severe defects in iodide uptake, suggesting that His-226 was critical for iodide uptake. Kinetic analysis further showed that mutation at His-226 led to a dramatic decrease in These findings suggested that the decreased levels of iodide uptake activity of SLC5A5 mutants resulted from lower catalytic rates. In Conclusion, our-data first identified the involvement of extracellular charged amino acid residue in the iodide uptake ability of SLC5A5.

Characteristics of the prolactin stimulation of iodide uptake into mouse mammary gland explants

We have recently reported that prolactin (PRL) stimulates iodide uptake into cultured mouse mammary tissues, This effect occurs in both TCA soluble and insoluble tissue fractions, The effect of PRL apparently involves an RNA-DNA-dependent mechanism, since actinomycin D and cyclohexamide abolish the PRL stimulation of iodide uptake and its incorporation into protein, Perchlorate and thiocyanate, inhibitors of the iodide transporter, also abolish the PRL effects on iodide uptake and incorporation. Similarly, propylthiouracil and aminotriazole, inhibitors of peroxidase, abolish both effects of PRL, Finally, the extent of iodide uptake in mammary cells is suppressed by about 50% in sodium-free medium, These studies thus suggest the existence of a sodium-iodide symporter in the mammary gland which has characteristics similar to the iodide transporter in the thyroid gland-that is, It is sodium dependent and is inhibited by perchlorate and thiocyanate, The fact that both iodide transporter inhibitors and peroxidase inhibitors abolish PRL-stimulated iodide uptake and incorporation suggests that there may be a coupled mechanism involving the iodide transporter and the peroxidase enzyme.

Iodide handling by the thyroid epithelial cell

Iodination of thyroglobulin, the key event in the synthesis of thyroid hormone, is an extracellular process that takes place inside the thyroid follicles at the apical membrane surface that faces the follicular lumen. The supply of iodide involves two steps of TSH-regulated transport, basolateral uptake and apical efflux, that imprint the polarized phenotype of the thyroid cell. Iodide uptake is generated by the sodium/iodide symporter present in the basolateral plasma membrane. A candidate for the apical iodide-permeating mechanism is pendrin, a chloride/iodide transporting protein recently identified in the apical membrane. In physiological conditions, transepithelial iodide transport occurs without intracellular iodination, despite the presence of large amounts of thyroglobulin and thyroperoxidase inside the cells. The reason is that hydrogen peroxide, serving as electron acceptor in iodide-protein binding and normally produced at the apical cell surface, is rapidly degraded by cytosolic glutathione peroxidase once it enters the cells. Iodinated thyroglobulin in the lumen stores not only thyroid hormone but iodine incorporated in iodotyrosine residues as well. After endocytic uptake and degradation of thyroglobulin, intracellular deiodination provides a mechanism for recycling of iodide to participate in the synthesis of new thyroid hormone at the apical cell surface.

Acyl iodides in organic synthesis: IV. Reaction of acetyl iodide with carboxylic acids

In contrast to acyl chlorides, reactions of acetyl iodide with monocarboxylic acids follow the exchange pattern to give the corresponding acyl iodides and acetic acid. The reaction attracts interest from the preparative viewpoint as a simple and convenient route to acyl iodides. Acetyl iodide reacts with phthalic acid, yielding acetic acid and phthalic anhydride, while the reaction of acetyl iodide with oxalic acid leads to formation of acetic acid, carbon(II) oxide, and molecular iodine.

DETERMINATION OF TRACE AMOUNTS OF LEAD AS IODIDE COMPLEX BY 3RD-ORDER DERIVATIVE SPECTROPHOTOMETRY

Third-order derivative spectrophotometry was used for the direct determination of trace amounts of lead as its iodide complex. Optimum conditions for the formation of the lead iodide complex as well as conditions for spectrum registration and obtaining its successive derivatives were chosen. The derivatives were calculated numerically using Savitzky-Golay method. The proposed direct method has been applied for determining lead (ca. 10(-4)%) in potassium iodide, zinc sulphate and cadmium sulphate with good precision and accuracy.
