(Rac)-Rotigotine hydrochloride 是 Rotigotine 的外消旋体。Rotigotine 是 dopamine receptor 激动剂，是 5-HT1A receptor 的部分激动剂，以及 α2B-adrenergic receptor 的拮抗剂，K_i 值分别为 0.71 nM (dopamine D3 receptor)，4-15 nM (D2，D5，D4 receptors)，83 nM (dopamine D1 receptor)。

(Rac)-Rotigotine hydrochloride is a racemate of Rotigotine. Rotigotine is a full agonist of dopamine receptor, a partial agonist of the 5-HT1A receptor, and an antagonist of the α2B-adrenergic receptor, with K i s of 0.71?nM, 4-15?nM, and 83?nM for the dopamine D3 receptor and D2, D5, D4 receptors, and dopamine D1 receptor.

D3 Receptor 0.71 nM (Ki) D2 Receptor

Rotigotine has a 10-fold selectivity for D3 (pKi=9.2) receptors compared with D2, D4 and D5 (pKi=8.5-8.0) and a 100-fold selectivity compared with D1 receptors (pKi=7.2). In functional studies, Rotigotine behaves as full agonist at all dopamine receptors but notably the potency for stimulation of D1 receptors is similar to that for D2 and D3 receptors (pEC50 respectively: 9.0, 9.4-8.6, 9.7).
Rotigotine (10 μM) decreases the number of THir neurons by 40% in primary mesencephalic cell culture. Rotigotine (0.01 μM) slightly protects dopaminergic neurons against MPP+ toxicity, significantly protects dopaminergic neurons against rotenone-induced cell death, and significantly inhibits ROS production by rotenone.
