BMS-819881 is a melaninconcentrating hormone receptor 1 (MCHR1) antagonist, which binds rat MCHR1 with a Ki of 7 nM and it also is selective and potent for CYP3A4 activity with an EC50 of 13 μM.
Potent melanin-concentrating hormone (MCH) receptor agonist (EC50 values are 17 and 54 nM at MCH1 and MCH2 receptors respectively). Displays some selectivity towards MCH1 over MCH2 (Ki values are 0.16 and 34 nM respectively).
BMS-814580 is a potent and selective functional antagonist (Kb = 117 nM) of human MCHR1. BMS-814580 exhibits potent binding affinity (Ki = 17 nM) for human MCHR1. BMS-814580 also exhibits potent binding affinities for cynomolgus monkey and rat MCHR1 (Ki o
Ac-hMCH(6-16)-NH2 shows non-selective agonist activity towards both MCH-1R and MCH-2R, which are human MCH receptors in the brain. The compound effectively binds to and activates these receptors, with IC 50 values of 0.16 nM and 2.7 nM for MCH-1R and MCH-2R, respectively.
