pw 0464

PW0464, a nanomolar potent complete G protein biased ligand, is a noncatechol D1R agonist, with an EC50 of 5.8 nM (Gs-cAMP)[1]. PW0464 (compound 24) is found to elicit complete G protein bias, showing no activity for D1R-mediated β-arrestin recruitment[1].PW0464 (compound 24), the non-catechol agonist, forms bonds with S1985.42 and S2025.46 via its fluorine atom[2].
