Biological Activity
Potent and selective tachykinin NK1 receptor antagonist (Ki values are 2.9 nM and > 10 μM for rat NK1, and rat NK2 and NK3 receptors respectively). Displays higher affinity at rat and mouse than human receptors. Antinociceptive in vivo, possibly partly via inhibition of calcium channels.
