[Ala17]-MCH acetate is a selective ligand for MCHR1 with a Ki of 0.16 nM and Kd of 0.37 nM(Eu3+ chelate-labeled). [Ala17]-MCH acetate shows selectivity over MCHR2 with Ki of 34 nM.
TC-MCH 7c is an oral, selectable and blood-brain barrier penetrating MCH1R antagonist with IC50 performance of 5.6 nM against hMCH1R, and TC-MCH 7c is a phenylpyridone derivative with MCH1R Ki of 3.4 nM against human. In mice, MCH1R Ki was 3.0 nM.
ATC 0175 hydrochloride is an orally active melanocyte concentrating hormone 1 receptor antagonist that is potent and selective. ATC 0175 hydrochloride has affinity for MCH1R, MCH2R, MCH1, 5-HT2B receptors and 5-HT1A receptors with IC50s of 13.5 nM, >10,000 nM, 13 nM, 9.66 nM and 16.9 nM, respectively. ATC 0175 hydrochloride exhibits antidepressant and anxiolytic effects in animal models. aTC 0175 can be used to study depression and or anxiety disorders.
MCH(human, mouse, rat) is a potent endogenous agonist at melanin-concentration hormone (MCH) receptors (IC50 values are 0.3 and 1.5 nM and EC50 values are 3.9 and 0.1 nM at MCH1 and MCH2 receptors respectively). Increases food intake in vivo.
SNAP 94847 (SNAP-94847) is a selective and competitive MCH1 receptor (MCH1-R) antagonist (Ki: 2.2 nM). It has anxiolytic and antidepressant activity and reduces food intake in mice.
