[ala17] mch

[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.

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).

[Ala17]-MCH TFA, a selective ligand for MCHR 1 (K i =0.16 nM) over MCHR 2 (K i =34 nM), is an analogue of MCH. When labeled with a [Eu 3+ chelate], [Ala17]-MCH exhibits high affinity for MCHR 1 (K d =0.37 nM) and negligible binding affinity for MCHR 2.
