SDZ MAR 327 is a new neuroleptic agent with high in vitro affinity for dopamine D1 and D2 receptors. The goal of this study was to determine the effect of time after SDZ MAR 327 administration on central dopamine D1 receptor occupancy in healthy humans. Positron emission tomography (PET) with the dopamine D1 receptor ligand, [11C] SCH 23390, was performed in 6 male volunteers (age 22-34), in both the drug naive state and at 1, 2 and 4 h after a single oral dose of SDZ MAR 327 (9 mg). The pre and post drug treatment [11C] SCH 23390 dynamic data were analyzed using two different methods, each yielding a parameter proportional to the receptor density: i) a simple regional comparison approximating the specifically bound to free fraction, B/F; and ii) a two compartment, two parameter model yielding the apparent distribution volume DV". With both methods, a metabolite corrected arterial input function was used and the vascular fraction of tissue (Vb) was fixed at a previously determined value of 4%. Method I served as a qualitative comparison of the paired studies and demonstrated little difference between the pre and post drug conditions, method II also confirmed that there was no significant change in binding of [11C] SCH 23390 in the striatum. These data indicate that SDZ MAR 327 produces little if any effect on dopamine D1 receptor binding at the dose used.
