生物活性
GR231118 TFA, an analogue of the C-terminus of neuropeptide Y, is a potent , competitive and relative seletive antagonist at human neuropeptide YY receptor with a pKi of 10.4. GR231118 a potent agonist at the human neuropeptide YY4 receptor (pEC50=8.6; pKi=9.6) and a weak agonist at the human and rat neuropeptide Y Y2 and Y5 receptors. GR231118 also has high affinity for the mouse neuropeptide YY6 receptor (pKi= 8.8)[1].
Room temperature in continental US; may vary elsewhere.
