The goal of the study aims to evaluate newly radioiodinated candesartan (CAN) as a potential cardiovascular tracer. CAN was labeled using 125 I with chloramine-T (Ch-T) and N-bromosuccinimide (NBS) with full characterization of cold Iodo-candesartan. Factors such as pH, reaction temperature, reaction time, substrate, and oxidizing agent amounts were studied to optimize the radioiodination of CA...

BNPS-skatole (3-bromo-3-methyl-2-(2-nitrophenyl)thiol-3H-indole) and N-bromosuccinimide have been used to specifically cleave at peptide bonds after amino acids with available C-gamma=C-delta double bonds, i.e. tryptophan, tyrosine and histidine. The resulting C-terminal lactones conveniently attach to amino-glass supports for sequencing with DABITC (4-NN-dimethylaminoazobenzene 4'-isothiocyana...

arthrobotrysamerospora (atcc 34468) produced glucoamylase in a semi-synthetic medium containing starch as a sole carbon source. polyacrylamide gel electrophoresis of crude glucoamylase showed three isoenzymes. they were designated as glu i, glu ii and glu iii according to their electrophoretic mobility. these iso-glucoamylases were purified by column chromatography using deae-sephadex a-50. the...

Abstract Regioselectivity of visible-light-induced transformations a range (hetero)aryl alkyl-substituted ketones bearing several competitive reactive sites ( ? -carbonyl, benzyl and aromatic ring) with N- bromosuccinimide (NBS) was studied under solvent-free reaction conditions (SFRC) in the absence inert-gas atmosphere, radical initiators catalysts. An 8-W energy-saving household lamp used fo...
