Notes: PSB-KD107 is an agonist of the orphan G protein-coupled receptor GPR18 (EC50 = 0.56 µM in a β-arrestin recruitment assay using CHO cells expressing the human receptor).{58090,44024} It is selective for GPR18 over GPR55, as well as cannabinoid 1 (CB1) and CB2 receptors, at 10 µM but also binds to the adenosine A2A receptor (Ki = 0.33 µM for the rat receptor).{58090,58091}
