NGD94-1
Based on 1 Customer Validation
NGD94-1 is a potent and selective dopamine D4 receptor antagonist. NGD94-1 shows high affinity for the cloned human D4.2 receptor (Ki = 3.6 nM). NGD94-1 modulates the cognitive functions of the frontostriatal system and regulates dopaminergic transmission in Phencyclidine (PCP)-induced monkeys. NGD94-1 can be used for neurological disease research[1][2].

hD4.2 Receptor 3.6 nM (Ki) |
NGD 94-1 shows >600-fold selectivity for the D4.2 receptor over many other targets; however, its selectivity is significantly lower over the 5-HT1A (~50-fold) and 5-HT3 (~200-fold) receptors[2].
NGD 94-1 induces inhibition of cAMP accumulation in HEK293/D4 cells, but does not affect Forskolin (HY-15371)-stimulated cAMP formation in non-transfected HEK293 cells, demonstrating that its inhibitory action is specifically mediated through the transfected dopamine D4 receptors[3].

Result:Significantly reversed the impaired successful performance of PCP-treated subjects (from 58% to 79% accuracy) at 1 mg/kg.
Ameliorated the PCP-induced impairments (from 73% to 86% accuracy) at 5 mg/kg.
Reduced barrier reaching and perseverative responding at both doses in PCP-treated monkeys.
Unaffected response initiation latencies and motor problems in PCP-treated monkeys.
Unaffected accurate performance at 1 mg/kg in saline pretreated monkeys.
Slightly impaired successful performance at 5 mg/kg in saline pretreated monkeys.
Failed to affect response initiation latencies or motor problems at both doses in saline pretreated monkeys.
Failed to affect HVA levels relative to saline in control subjects.
Significantly increased HVA concentrations in the CSF in PCP-treated subjects.
