FAUC 346, a highly selective D3 partial agonist (EC50 = 1.5 nM)[1][2].

FAUC 346, a highly selective D3 partial agonist (EC50 = 1.5 nM), also demonstrates an inhibitory effect on cocaine-seeking behavior[1][2]. FAUC 346, an in vitro D3-selective ligand with a Ki of 0.23 nM in CHO cells for D3 receptor[1].FAUC346 shows some affinity for 5HT1A receptors (Ki = 41 nM) and for α1 receptors (Ki = 15 nM)[1].
