PD-89211 is a selective dopamine D4 receptor antagonist with a Ki value of 3.7 nM. PD-89211 reverses Quinpirole (HY-B1752A)-induced [3H]thymidine uptake in CHOpro5 cells (IC50 = 2.1 nM). PD-89211 regulates dopamine/norepinephrine metabolism in the hippocampus and can be used for research on central nervous system disorders such as schizophrenia[1].
