SB 223412
Biological Activity
Potent and selective non-peptide NK3 receptor antagonist (Ki values are 1, 144 and >100000 nM for human NK3, NK2 and NK1 receptors respectively). Selective over a panel of >60 receptors, enzymes and ion channels at concentrations of 1 or 10 μM. Inhibits NKB-induced Ca2+ mobilization in vitro (IC50 = 16.6 nM) and inhibits NK3-agonist-induced behavioral responses in vivo. Orally active and brain penetrant.
