V M. ANDREOLl, A. AGNOLI, and C. FAZIO The transfer of a methyl
group from a donor to an acceptor compound is a fundamental
biochemie al process long since known to biologists; the process is
involved, for instance, in the metabolism of porphyrins, nuc1eic
acids, and fatty acids. Only recently, however, did
transmethylation processes reveal their decisive role in CNS
biochemistry - namely with the discovery that such processes are
linked with the biogenie amines that have been conc1usively
identified as the chemical mediators of neu- ronal transmission
and, more broadly, of behavior. The first suggestion that
transmethylation processes might be involved in the origina- tion
of certain mental diseases came from Harley-Mason (1952), who
noticed that many of the hallucinogenic substances known at that
time contained methyl radicals, and par- ticularly that mescaline
represented the product of O-methylation of dopamine in posi- tions
3, 4, and 5. This hypothesis was put forward when the O-methylation
of catechol- amines by catechol-O-methyltransferases had not yet
been described. Harley-Mason further proposed that in the living
organism the process of O-methyla- tion might follow a "deviant"
metabolie pathway, and that the accumulation of abnor- mal
methylated metabolites endowed with hallucinogenic properties might
be responsi- ble for the implementation of some mental diseases,
notably schizophrenia. He also called attention to a substance,
3,4-dimethoxyphenylethylamine (3,4-DMPEA) as a possible
psychotogenic moleeule, on the strength of its capacity for
producing cata- tonia in experimental animals.
