| Targets |
PD 144418 oxalate targets the sigma 1 (σ1) receptor as a potent and selective ligand. It has a Ki of 0.08 nM for the σ1 receptor and shows high selectivity over the σ2 receptor. By binding to σ1 receptors, it modulates various cellular processes, including calcium signaling and neuroprotection.

| ln Vitro |
N-methyl-D-aspartate (NMDA)-induced increases in cyclic GMP (cGMP) in rat cerebellar slices were reversed in vitro by PD 144418, without changing basal levels. This suggests that glutamine, specifically the σ1 site, may play a significant role in the control of induced cyclic GMP (cGMP). take action. PD 144418 has no effect on the synthesis of 5-HT or dopamine (DA) per se, but it amplifies the haloperidol-induced drop in 5-hydroxytryptophan in the mesolimbic region [1].
In vitro, PD 144418 oxalate is a potent and selective σ1 receptor ligand with a Ki of 0.08 nM. It shows high selectivity for σ1 over σ2 receptors. Its activity makes it a valuable tool for studying σ1 receptor function and its role in neurological and psychiatric disorders. |
| ln Vivo |
Male CD-1 mice treated with 10 mg/kg i.p. with PD 144418 were able to suppress mescaline-induced scratching, but the dose had no effect on spontaneous locomotor activity. The ED50 of PD 144418 is 7.0 mg/kg ip [1].
In vivo, PD 144418 oxalate is used as a research tool to study the role of σ1 receptors in various physiological and pathological processes. As a selective σ1 ligand, it can be administered to animal models to study its effects on neuroprotection, cognition, and pain. |
| Enzyme Assay |
In vitro receptor binding assays for PD 144418 oxalate involve measuring its affinity for σ1 and σ2 receptors. Radioligand binding studies using ³H-pentazocine or other σ ligands are performed on membranes from cells expressing the receptors. The compound is incubated with increasing concentrations, and Ki values are calculated.
|
| Cell Assay |
For in vitro cell-based assays, cells expressing σ1 receptors are cultured and treated with PD 144418 oxalate at various concentrations. Receptor activation is measured by quantifying downstream signaling pathways. Cell viability is assessed by standard assays. Its selectivity is confirmed by testing against σ2 receptors.
