Biological Activity

Potent human MC1 receptor antagonist (IC50 = 17 nM). Also partial agonist at human MC3 and MC5 receptors (EC50 values are 59 and 1300 nM, respectively). Exhibits binding affinity for A375 melanoma cells in vitro. Reverses morphine-induced hyperalgesia in female mice, with no effect in male mice. γMSH analog.

Preparing Stock Solutions

The following data is based on the product molecular weight 1347.51. Batch specific molecular weights may vary from batch to batch due to solvent of hydration, which will affect the solvent volumes required to prepare stock solutions.

Select a batch to recalculate based on the batch molecular weight:
Concentration / Solvent Volume / Mass 1 mg 5 mg 10 mg
1 mM 0.74 mL 3.71 mL 7.42 mL
5 mM 0.15 mL 0.74 mL 1.48 mL
10 mM 0.07 mL 0.37 mL 0.74 mL
50 mM 0.01 mL 0.07 mL 0.15 mL
