Despite its structural similarity to catechol, 2,3-dihydroxypyridine is not a substrate but a "dead-end" inhibitor of purified pig liver catechol-O-methyltransferase. It inhibits the methylation of 3,4-dihydroxyphenylacetic acid competitively with an inhibitor constant of 15 microM. Against the methyl donor, S-adenosyl-L-methionine
