rf 9

RF9 is an effective and selective antagonist of the Neuropeptide FF receptor (Kis: 58±5 and 75±9 nM for hNPFF1R and hNPFF2R, respectively).

RF9 hydrochloride is a potent and selective Neuropeptide FF receptor antagonist, targeting hNPFF1R (Ki: 58 nM) and hNPFF2R (Ki: 7 nM).

RF9 acetate is an effective and selective antagonist of Neuropeptide FF receptor with Ki values of 58 and 75 nM for hNPFF1R and hNPFF2R, respectively.

α-helical CRF 9-41 acetate is a competitive antagonist of CRF2 (KB = 100 nM) and a partial agonist of CRF1 (EC50 = 140 nM).

5-Methyltryptamine hydrochloride is a high-affinity 5-HT1C receptor ligand and a partial agonist of 5-HT. 5-Methyltryptamine hydrochloride protects mice subjected to burn, tourniquet and endotoxin shock.

α-Helical CRF (9-41) is a synthetic peptide antagonist that targets corticotropin-releasing factor (CRF), effectively inhibiting CRF-induced adrenocorticotropic hormone (ACTH) release both in vitro, with isolated rat anterior pituitary cells at concentrations of 0.5 to 5 µM, and in vivo, in non-anesthetized, intact rats at doses ranging from 0.02 to 0.6 µmol/kg. Moreover, it prevents stress-induced ACTH release at a dose of 0.6 µmol/kg in rats and demonstrates the ability to enhance social interaction times in a rat model addressing nicotine-induced conditioned anxiety, in addition to decreasing binge-like ethanol consumption in mice.

Corticotropin-releasing factor receptor antagonist (Ki values are 17, 5 and 0.97 at human CRF1, rat CRF2α and mouse CRF2β receptors respectively).
