2-Methoxyaniline (o-anisidine) and 2-methoxynitrobenzene (o-nitroanisole) are important pollutants and potent carcinogens for rodents. o-Anisidine is oxidized by microsomes of rats and rabbits to N-(2-methoxyphenyl)hydroxylamine that is also formed as the reduction metabolite of o-nitroanisole. o-Anisidine is a promiscuity substrate of rat and rabbit cytochrome P450 (CYP) enzymes, because CYPs ...

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...

The p-anisidine is widely used as chemical intermediate in the production of various dyes, pigments, and pharmaceuticals. This study was aimed to evaluate the effect of biofield energy treatment on the physicochemical and spectroscopic properties of p-anisidine. The study was performed after dividing the sample in two groups; one was remained as untreated and another was subjected to Mr. Trived...

HCI in lOml of methanol and diluting to IOOml with butan-1-o1;just before use, 0.1 g of sodium dithionite was added. The dried electrophoresis sheets were sprayed with the reagent and developed at 120°C for 1 5min. With 4and 6-sulphated disaccharides a strong colour-positive reaction occurred with p-anisidine at the highest amount examined (20pg) and a detectable coloured product was observed a...

A bioassay for possible carcinogenicity of p-anisidine hydrochloride was conducted using Fischer 344 rats and B6C3F1 mice. p-Anisidine hydrochloride was administered in the feed, at either of two concentrations, to groups of 55 male and 55 female animals of each species. Fifty-five animals of each sex and species were placed on test as controls. The high and low dietary concentrations of p-anis...

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...

Makaluvamine C is a pyrroloiminoquinone which has been isolated from marine sponges. This molecule has been synthesized in 13 steps from p-anisidine. The key steps in this synthesis include an intramolecular nucleophilic aromatic substitution mediated by potassiumtert-butoxide, the selective reduction of a dinitro ester using catalytic hydrogenation, and the novel use of Fremy's salt to synthes...

2-Methoxyaniline (o-anisidine) is an industrial and environmental pollutant causing tumors of urinary bladder in rodents. Here, we investigated the formation and persistence of DNA adducts in the Wistar rat. Using the (32)P-postlabeling method, three o-anisidine-derived DNA adducts were found in several organs of rats treated with a total dose of 0.53 mg o-anisidine/kg body wt (0.15, 0.18, and ...

Several structurally related anisidine and dibenzanthracene isomers were evaluated for genotoxic effects in the somatic w/w+ assay of Drosophila melanogaster employing insecticide-susceptible (IS) and insecticide-resistant (IR) tester strains. In addition, and in order to find whether or not at the genetic level a regulatory effect is found, crosses between ISxIR strains and IRxIS strains were ...

An aromatic amine, o-anisidine (2-methoxyaniline) and its oxidative counterpart, 2-nitroanisole (2-methoxynitrobenzene), are the industrial and environmental pollutants causing tumors of the urinary bladder in rats and mice. Both carcinogens are activated to the same proximate carcinogenic metabolite, N-(2-methoxyphenyl)hydroxylamine, which spontaneously decomposes to nitrenium and/or carbenium...
