PD 144418 is a highly affinity, potent and selective sigma 1 (σ1) receptor ligand (Ki values of 0.08 nM and 1377 nM for σ1 and σ2 respectively). PD 144418 devoids of any significant affinity for other receptors, ion channels and enzymes. PD 144418 shows potential antipsychotic activity.

体外研究(In Vitro)
体外研究, PD 144418 reverses the N-methyl-D-aspartate (NMDA)-induced increase in cyclic GMP (cGMP) in rat cerebellar slices without affecting the basal levels, suggesting that σ1 sites may be important in the regulation of glutamine-induced actions. PD 144418 potentiates the decrease in 5-hydroxytryptophan caused by Haloperidol in the mesolimbic region, but by itself has no effect in 5-HT and dopamine (DA) synthesis.
