Opis

General description

Methylhydroquinone is produced by the oxidation of o-cresol by the mutants G103S, G103S/A107G, and G103S/A107T[1].

Application

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.

Biochem/physiol Actions

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[2].
