Synthesis of spin-labeled emoxypine, methionine, o-anisidine

Enzymatic synthesis of multi spin-labeled DNA.

Electron paramagnetic resonance (EPR) spectroscopy was applied extensively in studies of nucleic acid structures and dynamics. Two modified 2'-deoxyuridine triphosphates were synthesized bearing a spin label linked to the base by a rigid linker to ensure a tight coupling of spin label dynamics. The incorporation of both spin-labeled nucleotides could be shown in primer extension reactions in pr...

Synthesis of Silver Embedded Poly(o-Anisidine) Molybdophosphate Nano Hybrid Cation-Exchanger Applicable for Membrane Electrode

Poly(o-anisidine) molybdophosphate was expediently obtained by sol-gel mixing of Poly(o-anisidine) into the inorganic matrices of molybdophosphate, which was allowed to react with silver nitrate to the formation of poly(o-anisidine) molybdophosphate embedded silver nano composite. The composite was characterized by Fourier Transform Infrared Spectroscopy, X-ray powder diffraction, UV-Vis Spectr...

Bioassay of 5-nitro-o-anisidine for possible carcinogenicity.

A bioassay of 5-nitro-o-anisidine for possible carcinogenicity was conducted using Fischer 344 rats and B6C3F1 mice. 5-Nitro-o-anisidine was administered in the feed at either of two concentrations, to groups of 50 male and 50 female animals of each species. The dietary concentrations used in the chronic bioassay for low and high dose rats were 0.4 and 0.8 percent, respectively. Dose A and B mi...

Tissue distribution, excretion and metabolism of o-anisidine in rats.

OBJECTIVES The principal commercial use of o-anisidine is believed to be as an intermediate in the manufacture of dyes. It has also been reported to be an intermediate in the manufacture of synthetic guaiacol and its derivatives. o-Anisidine is an urinary bladder carcinogen in mice and rats. The aim of the study was to investigate the kinetics of body distribution, excretion and biotransformati...
