Descrição geral
Methylhydroquinone is produced by the oxidation of o-cresol by the mutants G103S, G103S/A107G, and G103S/A107T.
Aplicação
Methylhydroquinone can be used as a reactant to prepare:
- A semiflexible thermotropic polyester via polycondensation reaction with 4,4′-sebacoyldioxydibenzoyl chloride.
- A sesquiterpene (±)-helibisabonol A.
- poly{hexakis[(methyl)(4-hydroxyphenoxy)]cyclotriphosphazene} by reacting with hexachlorocyclotriphosphazene.
- 6-Hydroxy-4,7-dimethyl-2H-1-benzopyran-2-one by treating with ethyl acetoacetate in the presence of H2SO4 as a catalyst.
Ações bioquímicas/fisiológicas
Methylhydroquinone (Toluquinol) inhibits the growth of endothelial and tumor cells in culture in the micromolar range and is a promising drug candidate in the treatment of cancer and other angiogenesis-related pathologies.

Wild-type toluene 4-monooxygenase (T4MO) of Pseudomonas mendocina KR1 oxidizes toluene to p-cresol (96%) and oxidizes benzene sequentially to phenol, to catechol, and to 1,2,3-trihydroxybenzene. In this study T4MO was found to oxidize o-cresol to 3-methylcatechol (91%) and methylhydroquinone (9%), to

Catechol and 2-methylhydroquinone (2-MHQ) cause the induction of the thiol-specific stress response and four dioxygenases/glyoxalases in Bacillus subtilis. Using transcription factor arrays, the MarR-type regulator YkvE was identified as a repressor of the dioxygenase/glyoxalase-encoding mhqE gene. Transcriptional and proteome analyses

Various polymeric oxidation products of polyphenols strongly inhibited the purified lipoxygenase of rabbit reticulocytes, whereas the prostaglandin H synthase of sheep vesicular gland was only weakly inhibited. The oxidized polymeric preparations of caffeic acid, 2,5-dihydroxytoluene and 3,4-dihydroxytoluene were the most

Bacillus subtilis is exposed to a variety of antimicrobial compounds in the soil. In this paper, we report on the response of B. subtilis to the fungal-related antimicrobials 6-brom-2-vinyl-chroman-4-on (chromanon) and 2-methylhydroquinone (2-MHQ) using proteome and transcriptome analyses. Chromanon, a

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
