| In vitro | In vitro, PD 144418 counteracts the increase in cyclic GMP (cGMP) triggered by N-methyl-D-aspartate (NMDA) in rat cerebellar slices, without altering basal levels. This implies a significant role for σ1 sites in controlling actions induced by glutamine. Furthermore, PD 144418 enhances the reduction of 5-hydroxytryptophan induced by Haloperidol within the mesolimbic region, although it does not independently affect 5-HT and dopamine (DA) synthesis [1]. |
| In vivo | Treatment with PD 144418 (10 mg/kg; intraperitoneal injection; male CD-1 mice) effectively antagonized Mescaline-induced scratching without affecting spontaneous motor activity, displaying an ED 50 of 7.0 mg/kg (i.p.). This outcome was observed in a study where male CD-1 mice were administered a single intraperitoneal dose of 10 mg/kg, resulting in the inhibition of scratching behaviors induced by Mescaline. |
