Biological Activity for RF 9

RF 9 is a selective NPFF receptor antagonist (K_i values are 58 and 75 nM at hNPFF₁ and hNPFF₂ receptors respectively). Displays selectivity over several related receptors including NPY Y₁ GPR10, GPR54, GPR103 and the opioid receptors. Blocks NPFF-induced hypothermia and increases in atrial blood pressure and heart rate, and prevents opioid-induced tolerance associated with hyperalgesia in vivo.
