3-methoxy- and 3,5-dimethoxy-substituted 4-hydroxy-benzaldehydes, -benzoic acids, and -acetophenones are the preferred substrates. The corresponding 3,4-dihydroxy compounds are methylated relatively slowly, while the 3-hydroxy-4-methoxy compounds are almost inactive as substrates. Substituents in both the 2 and 4 positions relative to the hydroxyl group appear to be essential for significant enzyme attack of a substrate. Xenobiotic compounds such as 2,4-dichlorophenol and 2,4-dibromophenol are methylated almost as readily as 4-hydroxy-3-methoxyacetophenone. No substrates: homovanillic acid, caffeic acid, ferulic acid |
