Dopamine Receptors

(+)-PD 128907 hydrochloride is a potent D3DR (dopamine receptor) agonist (Ki = 2.3 nM).

UNC 9994 hydrochloride, unique, beta-arrestin-biased functionally selective dopamine D2 receptor (D2R) agonist (Ki value 30 nM; EC50 value 50 nM in ??-arrestin-2 recruitment assay) that exhibits antipsychotic activity in vivo. UNC9994 markedly inhibited PCP-induced hyperlocomotion in wild-type mice, which effect was completely abolished in ??-arrestin-2 knockout mice.

Cariprazine is a novel antipsychotic drug candidate that exhibits high affinity for the D3 (Ki=0.085 nM) and D2 (Ki=0.49 nM) receptors, and moderate affinity for the 5-HT1A receptor (Ki=2.6 nM).

SKF-82958 hydrobromide is a D1/D5 receptor full agonist.
