Biological Activity for NGB 2904

NGB 2904 is a potent and selective dopamine D₃ receptor antagonist (K_ivalues are 1.4, 217, 223, 642, > 5000, > 10000 and > 10000 nM for D₃, D₂, 5-HT₂, α₁, D₄, D₁ and D₅ receptors respectively). Potently antagonizes quinpirole-stimulated mitogenesis (IC₅₀ = 6.8 nM). Attenuates cocaine's rewarding effects and inhibits relapse to drug-seeking behavior.
