Kinetic investigations on Pd(II) catalyzed oxidation of D-ribose and D-arabinose by acidic solution of chloramine-T in the presence of mercuric acetate, as a scavenger have been made in the temperature range of 30°-45°C. The rate shows first order kinetics in case of chloramine-T and order of reaction is zero and one with respect to substrate and Pd(II) respectively. Increase in [Cl] showed pos...

Iodinated derivatives of adrenocorticotropic hormone (ACTH) were prepared with the use of NaI and chloramine-T and isolated by isoelectric focusing. The monoiodinated derivative (p1 7.6) was resolved into [monoiodoTyr2]ACTH and [monoiodoTyrZ3]ACTH by chromatography on columns of carboxymethylcellulose. Both monoiodo-AC’IH species exhibited only 30% of the maximum hormonal activity when assayed ...

One titrimetric and two spectrophotometric procedures have been reported for the determination of albendazole and its tablets. Using titrimetry, the drug was titrated directly with Chloramine-T under acidic conditions using a Methyl Orange indicator. The spectrophotometric procedures involve treating the sample solution with a measured excess of Chloramine-T in an acid medium, followed by an es...

Sublethal concentrations (sub-MICs) of certain disinfectants are no longer effective in removing biofilms from abiotic surfaces and can even promote the formation of biofilms. Bacterial cells can probably adapt to these low concentrations of disinfectants and defend themselves by way of biofilm formation. In this paper, we report on three Staphylococcus aureus biofilm formers (strong B+++, mode...

Traditional treatments of parasitic and bacterial diseases are based on chemotherapeutic compounds such as chloramine-T and CuSO4. Although many compounds are used in fish treatments, their undesirable effects are not known. In this study, glucose 6-phosphate dehydrogenase (G6PD) was purified from rainbow trout (Oncorhynchus mykiss) erythrocytes by hemolysate preparation, ammonium sulfate preci...

Introduction: Many molecules can be labeled by iodine. Some of labeled substances are used for investigations of cancer treatment, biodistribution study in body, receptor binding, secrete pathway etc. Peptides are biomolecules and can be labeled by 131Iodine. ICD- 85 is a tri-peptide derived from Iranian brown snake venom and scorpion venom. This tri-peptide treats cancer by i...

Three new methods are described for the assay of lamivudine in bulk drug and in tablet dosage forms using chloramine-T and two dyes, methyl orange and indigo carmine, as reagents. In titrimetry, aqueous solution of lamivudine is treated with a measured excess of chloramine-T in sulphuric acid medium and after the oxidation of lamivudine is judged to be complete, the unreacted oxidant is determi...
