Synthesis of Zinc O, O-diisobutyldithio [35S] phosphate, Using an Exchange Reaction of Elemental Sulfur [35S]

The preparation of [35S]homocysteine thiolactone free of [35S]methionine.

The unambiguous study of homocysteine metabolism requires a source of [355]homocysteine completely free from contaminating [35S]methionine. Until now, such a reagent has not been readily available. Homocysteine is an important metabolite involved in methionine, cysteine and methylation metabolism. Homocysteine can be methylated to form methionine with either 5-methyltetrahydrofolate [1] or beta...

Expression of ricin under control of three different promoters, Cauliflower mosaic virus 35S promoter (35S), dual enhanced Cauliflower mosaic virus 35S promoter (35S)

The Metabolism of L-serylglycine O(35s)-sulphate in the Rat.

1. The preparation of potassium l-serylglycine O-sulphate and the corresponding (35)S-labelled ester is described. 2. Intraperitoneal injection of potassium l-serylglycine O[(35)S]-sulphate to rats results in about 75% of the radioactivity of the dose appearing in the urine within 48hr. Almost 72% of the radioactivity recovered in the urine was in the form of inorganic [(35)S]sulphate. 3. Analy...

synthesis of amido alkylnaphthols using nano-magnetic particles and surfactants

we used dbsa and nano-magnetic for the synthesis of amido alkylnaphtols.

Quantitative assessment of reactive metabolite formation using 35S-labeled glutathione.

The metabolic bioactivation of a drug to a reactive metabolite (RM) and its covalent binding to cellular macromolecules is believed to be involved in clinical adverse events, including idiosyncratic drug toxicities. Therefore, it is important to assess the potential of drug candidates to generate RMs and form drug-protein covalent adducts during lead optimization processes. In this study, the R...
