RFRP-1(human) is a gonadotropin-inhibitory hormone (GnIH) homolog. RFRP-1(human) targets human gonadotropin-releasing hormone (GnRH) neurons and gonadotropes and potently inhibits gonadotropin. RFRP-1(human) is a potent Neuropeptide FF (NPFF) receptor agonist with EC50s of 0.0011 nM and 29 nM for NPFF2 and NPFF1, respectively[1][2][3].
RFRP-1(human) rapidly and reversibly decreases shortening and relaxation in isolated mammalian cardiac myocytes in a dose dependent manner[2].
Intravenous injection of RFRP-1(human) in mice decreases heart rate, stroke volume, ejection fraction, and cardiac output[2].
