A potential 5-HT1A receptor antagonist, p-MPPI, 4-(2'-methoxy-)phenyl-1-[2'-(n-2"-pyridinyl)-p-iodobenzamido-]ethy l- piperazine, was developed. The [125I]p-MPPI demonstrated high affinity and selectivity toward 5-HT1A receptors; Kd = 0.36 nM and Bmax = 264 fmol/mg of protein in rat hippocampal membrane homogenates. The binding is

Binding characteristics of a radioiodinated serotonin-1A (5-HT1A) receptor antagonist, 4-(2'-methoxy-phenyl)-1-[2'-(n-2"-pyridinyl)-p- iodobenzamido]-ethyl-piperazine ([125I]p-MPPI) were evaluated using in vitro homogenate binding and autoradiographic techniques in rat brains. [125I]p-MPPI displayed a Kd value of 0.32 +/- 0.04 nM (in the presence of MgCl2)
In vivo binding of [125I]4-(methoxyphenyl)-1-[2'-(N-2″-pyridinyl)-p-iodo-benzamido]-ethylpiperazine, p-MPPI, to 5HT1A receptors in rat brain.
