Neuropeptide FF receptor agonist (Ki values are 48.4 and 12.1 nM for NPFF1 and NPFF2, respectively). Potentiates the antinociceptive action of morphine in vivo and reverses the loss of morphine potency in tolerant animals. Also increases the amplitude of the sustained current of heterologously expressed acid sensing ion channel 3 (ASIC3) (EC50 ~ 50 μM).

Preparing Stock Solutions
The following data is based on the product molecular weight 888.03. 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.
|Concentration / Solvent Volume / Mass||1 mg||5 mg||10 mg|
|1 mM||1.13 mL||5.63 mL||11.26 mL|
|5 mM||0.23 mL||1.13 mL||2.25 mL|
|10 mM||0.11 mL||0.56 mL||1.13 mL|
|50 mM||0.02 mL||0.11 mL||0.23 mL|
