MLS1547 is a highly efficacious G protein-biased dopamine D2 receptor (D2R) agonist (Ki=1.2 μM). MLS1547 stimulates D2R G protein-mediated signaling (EC50=0.37 μM in a calcium mobilization assay). MLS1547 acts as an antagonist for dopamine (DA)-stimulated β-arrestin recruitment to the D2R (IC50=9.9 μM)[1][2].
MLS1547 fully antagonizes dopamine-mediated β-arrestin recruitment to the D2R in the DiscoveRx assay, with an IC50 of 9.9 μM. Similar results were obtained when MLS1547 was examined for antagonist activity in the D2R β-arrestin BRET assay, demonstrating an IC50 of 3.8 μM. MLS1547 is found to completely displace [3H]methylspiperone binding to the D2R, with a calculated Ki of 1.2 μM[1].
