PD-168077 maleate is a selective dopamine D4 receptor agonist, with a Ki of 9 nM.

IC50 & Target

D4 Receptor


In Vitro

PD-168077 is one of the first agents to be identified as putative selective D4 agonists. It shows >100-fold selectivity over other members of the D2-like receptor family and over their D1-like counterparts; PD-168077 shows a 20-fold selectivity over α1, and α2, a 45-fold selectivity over 5-HT1A, and a 460-fold selectivity over 5-HT2A receptors; PD-168077 evidences intrinsic activity at the D4 receptor in terms of quinpirole-like inhibition of forskolin-stimulated cAMP accumulation or stimulation of [3H]thymidine uptake? in CHO cells expressing the human D4 receptor[1]. In the PD-168077-treated cell, p-CaMKII exhibits a significantly increased clustering at synaptic sites, as indicated by the enhanced colocalization with PSD-95[2].

In Vivo

PD-168077 (0.2-25.0 mg/kg) dose-dependently induces locomotion, which takes an unusual and characteristic ”shuffling” form with uncoordinated movements together with yawning, and episodes of myoclonic jerking; grooming, and rearing are reduced[1].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
