The possible tumor-promoting and tumor-initiating activities of p-methylcatechol and methylhydroquinone in the pyloric mucosa of male F344 rats were studied. Ornithine decarboxylase (ODC) and replicative DNA synthesis (RDS) were used as markers of tumor promotion and DNA single strand scission
Toluquinol, a methylhydroquinone produced by a marine fungus, was selected in the course of a blind screening for new potential inhibitors of angiogenesis. In the present study we provide the first evidence that toluquinol is a new anti-angiogenic-compound. In a

The dioxygenolytic catabolism of five C-methylated hydroquinones and 2,6-dichlorohydroquinone in Pseudomonas sp. strain HH35 was elucidated. This organism, which is known to catabolise 2,6-dimethylhydroquinone by 1,2-cleavage, accumulated metabolites from 2-methyl-, 2,3-dimethyl-, 2,5-dimethyl-, 2,3,5-trimethyl- and 2,3,5,6-tetramethylhydroquinone which we isolated and characterised
A crude extract that catalyzes the epoxidation of toluquinol and gentisyl alcohol was isolated from cultures of Penicillium patulum. About 60% of the activity sedimented from crude extract upon centrifugation at 105,000g for 2 h, and at 30,000g for 30
Recently, we showed that the MarR-type repressor YkvE (MhqR) regulates multiple dioxygenases/glyoxalases, oxidoreductases and the azoreductase encoding yvaB (azoR2) gene in response to thiol-specific stress conditions, such as diamide, catechol and 2-methylhydroquinone (MHQ). Here we report on the regulation of
