Effects of alternative transmitter amines on cyclic AMP formation in rat brain tissue

Aromatic amines and related compounds, some of which are taken up and released from nerve terminals, might act at brain receptors ordinarily stimulated by traditional amine neurotransmitters. Several of these compounds were evaluated for their ability to stimulate or impede synthesis of cyclic AMP in rat striatal homogenates and cortical slices. In contrast to catecholamines, most had no effect, consistent with their possible role as false transmitters.
