UNC0006 is a β-arrestin-biased dopamine D2 ligand for probing signal transduction pathways essential for antipsychotic efficacy. Elucidating the key signal transduction pathways essential for both antipsychotic efficacy and side-effect profiles is essential for developing safer and more effective therapies. Noncanonical modes of dopamine D(2) receptor (D(2)R) signaling via β-arrestins are important for the therapeutic actions of both antipsychotic and antimanic agents
