Amino-(3,4-dihydroxyphenyl)methyl phosphonic acid, thephosphonic analogof 3,4-dihydroxyphenylglycine, hadbeenpreviously reported as a potent inhibitor of tyrosinase. Themechanism of the apparent enzyme inhibition by this com-pound has now been established. Amino-(3,4-dihydroxy-phenyl)methyl phosphonic acid turned out to be a substrateand was oxidized too-quinone, which evolved to a finalproduct identified as 3,4-dihydroxybenzaldehyde, the sameas for 3,4-dihydroxyphenylglycine.
