Pathology of 2-alkyl and 2-hydroxy naphthoquinone toxicity in rats
1a Toxicology and Food Safety Research Group, AgResearch , Ruakura Research Centre , Hamilton , New Zealand.
Abstract:
Abstract Extract The oral administration of 2-methyl-1, 4-naphthoquinone (menadione) to rats caused oxidative destruction of the erythrocyte. Heinz body formation occurred in erythrocytes, lowered PCVs and haemoglobin Occurred in blood, with splenic and hepatic erythroclasis, and iron conservation in the spleen, liver and kidney. These effects diminished when increasingly large alkyl substitutions of the methyl group of thi naphthoquinone were made. No effect was caused by the 2-decyl derivative.

Oxidation of Phenols to Quinones
o-hydroxy phenols are oxidized to o-quinones and p-hydroxy phenols to p-quinones. Such redox reactions involve the transfer of two electrons and two protons. The reversible redox property is crucial in...
