PD 144418 oxalate is a remarkably potent and selective sigma1 receptor ligand having potential antipsychotic properties. PD 144418 oxalate displayed an apparent affinity (Ki) of 0.08 nM for sigma1 sites in guinea pig brain membranes and a Ki of 1377 nM for sigma2 sites in rodent neuronal NG108-15 cell membranes. PD 144418 oxalate was classified as sigma1 receptor antagonist based upon several assays, including the ability to attenuate mescaline-induced scratching in mice. PD 144418 oxalate attenuates cocaine-induced hyperactivity in mice. It showed potential antipsychotic activity, but no antidepressant or anxiolytic actions.

CNS Activity

Curator's Comment: In vivo, PD 144418 oxalate bound to central and peripheral σ1 sites in mouse, with an ED50 of 0.22 umol/kg in whole brain. It antagonizes mescaline-induced scratching in mice following i.p. administration. Also attenuates cocaine-induced hyperactivity in mice.

Sample Use Guides

Mice: the effects of PD 144418 oxalate (1 and 10 mg/kg) on cocaine-stimulated (1, 3 and 10 mg/kg) locomotor activity was evaluated. PD 144418(10 mg/kg) was also tested against haloperidol (0.1, 0.3 and 1 mg/ kg)-induced suppression of locomotor activity. In each study, PD 144418 oxalate was administered 30 min prior to testing, and cocaine or haloperidol was administered 10 min before the 1 hr locomotor activity test. All injections were i.p.
Route of Administration: Intraperitoneal
In Vitro Use Guide
PD 144418 oxalate reversed the NMDA-induced increase in cGMP levels with IC50 value of 4.5 uM in rat cerebella slices.
