Résumé

Une activité considérable de la 3,4-dihydroxyphénylealanine (DOPA) décarboxylase a été démontrée chez un transplantable mélanome malin du hamster. Après l'injection intrapéritonéale du précurseur de la dopamine, l'amine nouveau-formée était trouvée dans toutes les tumeurs. L'inhibition de la DOPA décarboxylase par traitement des hamsters avec α-méthyle-DOPA n'a pas influé sur le progrès des tumeurs.
