[The affinity of aromatic fluoride derivatives of phenothiazine neuroleptics to spiroperidol binding sites of dopamine receptors by the radioligand technic in vitro].

By introduction of fluorine into the position 7 of butaperazine, chlorpromazine, methoxypromazine, perphenazine, prochlorperazine or into the position 3 of promazine derivatives are obtained with higher affinities for the 3H-spiroperidol binding site of the dopamine receptor compared with the corresponding substances free of fluorine.
