NEMONAPRIDE

Description

Nemonapride is a potent dopamine D₂receptor antagonist antipsychotic reported to have superior efficacy against hallucinations and delusions and also to be effective in the treatment of negative symptoms. The compound is a benzamide diastereomer and, although more potent than haloperidol, side effects are reported to be few primarily akinesia and some muscle rigidity with extrapyramidal symptoms being rare.

Description

Nemonapride is an antipsychotic that readily passes through the blood brain barrier and exhibits potent neuroleptic effects in animals. It binds dopamine 2 (D₂)-like receptors preferentially over D₁-like receptors (K_is = 0.06, 0.3, and 0.15 nM for D₂, D₃, and D₄, respectively). Nemonapride also binds sigma 1 (σ1) and σ2 receptors (K_is = 8.4 and 9.6 nM, respectively) and activates the serotonin 1A receptor (5-HT_1A; IC₅₀ = 34 nM).

Biological Activity

Highly potent dopamine D 2 -like receptor antagonist; selective over D 1 -like receptors (K i values are 0.1 and 740 nM for D 2 -like and D 1 -like receptors respectively). Also potent 5-HT 1A receptor agonist (IC 50 = 34 nM) and has affinity for sigma receptors.
