Chemical Name: N-[(2E)-5-Amino-5-methyl-1-oxo-2-hexenyl]-N-methyl-3-(2-naphthalenyl)-D-alanyl-N,Nα-dimethyl-D-phenylalaninamide hemifumarate
Biological Activity
Potent, orally active ghrelin receptor (GHS-R1a) agonist (Ki = 50 nM at human recombinant GHS-R1a). Stimulates GH release from rat pituitary cells with an EC50 value of 2.7 nM. Induces hyperphagia and adiposity in lean rats, but not in leptin signaling-deficient ZDF rats.

Molarity Calculator
Calculate the mass, volume or concentration required for a solution

The molarity calculator is based on the following equation:

Mass (g) = Concentration (mol/L) x Volume (L) x Molecular Weight (g/mol)
An example of a molarity calculation using the molarity calculator:
What is the mass of compound required to make a 10 mM stock solution in 10 ml of water given that the molecular weight of the compound is 197.13 g/mol?
