| Target | Ki: 58±5 nM (hNPFF1R), 75±9 nM (hNPFF2R)[1] |

| In Vivo | RF9 (10 μg) infused alone does not result in a significant alteration of MAP or heart rate. Conversely, MAP and heart rate increases evoked by NPFF are significantly blocked when NPFF is applied in conjunction with RF9[1]. It is worthy to note that RF9 (30 nmol) significantly reduces the hypothermia induced by morphine (5 nmol)[2]. |

| Animal Admin | Rats: Rats (n=5) are catheterized for measurement of arterial blood pressure and receive an in-dwelling cannula into the lateral cerebral ventricle. Arterial blood pressure and heart rate are continuously monitored. NPFF (10 μg in 10 μL of saline) is injected into the lateral ventricle over 15 to 20 sec. Control injections of saline (10 μL) are carried out in the same animals. Upon return of blood pressure to baseline, RF9 (10 μg) is injected i.c.v., followed by another i.c.v. injection of NPFF with RF9. After 1.5 h., another i.c.v. infusion of NPFF is repeated[1]. |
