CP-601927 is a selective α4β2 nicotinic acetylcholine receptor (nAChR) partial agonist (Ki=1.2 nM; EC50=2.6 μM). CP-601927 shows good brain penetration and antidepressant-like properties[1][2].
CP-601927 (0.125 mg/kg-1.5 mg/kg; i.p.; C57BL/6J male mice) has antidepressant-like activity in animal models[2].
