McN-5652 is one of a series of substituted pyrrolo-isoquinolines that, as a group, potently inhibit the uptake of one or more of the monoamines, norepinephrine, serotonin and dopamine. Receptor binding experiments indicated that McN-5652 has a weak affinity for serotonin 5-HT2 and alpha-1 adrenergic receptors. Abnormalities of the 5-HT transporter have been suggested in mood disorders, since it is one of the major binding sites of antidepressants. (+)-[11C]McN 5652 is an appropriate radiotracer to quantify 5-HT transporters in regions with relatively high concentration of 5-HT transporters, such as the midbrain, thalamus, and basal ganglia, and should prove useful in elucidating abnormalities of 5-HT transmission in neuropsychiatric conditions.

(+)-[11C]McN5652 injected dose (ID) was 580±128 MBq and the injected mass was 13.3±4.4 nmol. For (-)-[11C]McN 5652 the ID was 625±88 MBq and the injected mass was 18.6±16.1 nmol.

Intravenous
When tested at concentrations of 34 nM to 3.4 uM, McN-5652-Z-68 gave no indication of competitive antagonism against acetylcholine or histamine. A nonparallel shift of the acetylcholine concentration-response curve occurred when McN-5652-Z-68 was tested at concentrations of 340 nM and higher. A moderate but statistically significant increase in ED50 values for histamine was observed
with McN-5652-Z-68 at 34 and 340 nM, but this inhibition was not competitive as indicated by the slope of the Schild plot (about 0.5). At 3.4 uM, McN-5652-Z-68 marginally relaxed smooth muscle.
