Abstract
In previous work (Tanimukai (et al., 1968, pp. 6–15; 1970), we had made behavioral and biochemical observations on four chronic schizophrenic patients before, during and after a chemical stress evoked by the administration of tranylcypromine (Parnate) and later adding L-cysteine to the tranylcypromine. We observed the excretion of N-dimethyltryptamine, bufotenin and 5-methoxy-N-dimethyltryptamine in 24-hour urinary samples. These potentially psychotogenic compounds appeared in the urine in increased concentrations approximately two weeks before behavioral exacerbations and receded only in association with the restoration of the clinical picture observed before the behavioral worsening. In Fig. 1 are presented the naturally occurring amines and their potentially psychotomimetic derivatives. These reactions are facilitated by the enzyme discovered by Axelrod (1961) chiefly in the rabbit lung and more recently by Morgan and Mandell (1969) in the human brain.
