Kinetics and mechanism of iodination of 1-methylpyrazole
A spectrophotometric method was used to determine the rate law in buffered aqueous iodine-iodide solutions. Three iodinating agents other than iodine were considered: direct attack by hypoiodous acid, acid catalyzed attack by hypoiodous acid, and the iodinium ion. The first two were discarded …

A Study of Cell Surface Change After Viral Transformation by Iodination and Cell-Cycle Dependent Phosphorylation of Sv-40 Large Tumor Antigen
… thesis consists of two parts. Part I deals with iodination of the cell surface protein before and after viral transformation and Part II deals with cell-cycle dependent phosphorylation of the large tumor antigen induced by SV-40 in human cells.

MOLECULAR RECOGNITION OF THYROGLOBULIN BY SORTILIN
… the thyroid follicle lumen, where it undergoes iodination and hormonogenesis before being retrieved through endocytosis for hormone release. Despite its central role in thyroid physiology, the mechanisms governing TG uptake remain poorly understood. Sortilin, a ubiquitous receptor involved in …

Aspects of the chemistry of milk protein films formed on stainless steel
… the various methods for labelling proteins, radioiodination by a slightly modified version of Hunter and Greenwood Chloramine T method proved to be the most satisfactory. By this method, stable labelled milk proteins of high specific activity containing not more than one iodine atom per protein …

Sustainable strategies for alcohol halogenation
… explored, particularly with respect to alcohol iodination, where solvent-free conditions have been applied and process green metrics evaluated. This developed methodology offers a practical and competitive route to alcohol iodination/chlorination, characterised by reduced halide waste production …

Radioimmunoassay of insulin and glucagon with studies on the obese hyperglycaemic syndrome in mice
… plasma albumin. The conventional chloramine-T iodination with purification by gel chromatography was only suitable for the production of labelled insulin. Quality tracer for use in the glucagon radioimmunoassay was prepared by trace iodination, with subsequent purification of monoiodinated …

Effects of in vivo dexamethasone sodium phosphate on in vitro equine neutrophil function
… normal horse neutrophils. Neither phagocytosis, iodination, or phagosome-lysosome fusion was affected by treatment. Hydrogen peroxide production, measured both spectrophotometrically and by flow cytometry, was not affected by treatment. Lysosomal enzyme activity for alkaline phosphatase, acid …

Studies of Plant Viroid RNA and Other RNA Species of Unusual Function
… both in complexity and in specific pattern. Iodination as used here is thus a general labeling procedure, and appears principally to label cytidine residues. This iodination method shows little sensitivity to potential structure in single-stranded RNA molecules, yields stable oligonucleotide …

Synthetic Design of Multiphase Systems for Advanced Polymeric Materials
… of halogen identity. For both bromination and iodination, blocky halogenation of PEEK provides faster crystallization kinetics, higher glass transition (Tg) and melting temperatures as well as superior crystallizability than random halogenation. When comparing halogen identity, increasing …

Synthesis, Structure and Properties of New Iodine Derivatives of Natural Aromatic Acids // Синтез, структура и свойства на нови йодопроизводни на природни ароматни киселини
Iodination reactions of organic substrates are one of the most significant chemical transformations in pharmaceutical synthesis. No less important are the reactions that use the already obtained iodine-substituted compounds for the synthesis of much more complex ones. In addition, in view of the …

A Contribution to the Chemistry of 1,2,3-BENZOTHIADIAZOLE
… of 1,2,5-henzothiadiazole and the chlorination, iodination, diazo-coupling, and nitration of the four amino-l,2,3--henzothiadia2oles and some of their N~acyl derivatives have been studied. Differences in the 300-350 region of the spectra of 2- and 4-phenylazo-l-naphthylamines are found in …
