Four 7-[3-(4-phenyl-1-piperazinyl)propoxy]coumarins were synthesized. The a
ffinities of these compounds for DA (D-2A, D-3) and 5HT(1A) receptors were
evaluated for their ability to displace [H-3]-raclopride and [H-3]-8-OH-DPA
T respectively from their specific binding sites. The affinities of the tar
get compounds were all in the nanomolar range and followed the order 5-HT1A
