Assay Description
Rotigotine (N-0923) is 10 times more selective for D3 (pKi 9.2) receptors than D2, D4 and D5 (pKi 8.5-8.0), and 100% more selective for D1 receptors (pKi 7.2) Times. In functional studies, rotigotine (N-0923) is a complete agonist at all dopamine receptors, but it is worth noting that the stimulating ability of the D1 receptor is similar to the D2 and D3 receptors (pEC50 is 9.0, respectively), 9.4-8.6, 9.7) [1]. Rotigotine (N-0923) (10 µM) reduced the number of THir neurons in primary mesencephalic cell culture by 40%. Rotigotine (0.01 µM) can slightly protect dopaminergic neurons from MPP + toxicity, significantly protect dopaminergic neurons from rotenone-induced cell death, and significantly inhibit rotenone-induced ROS production [4].

Assay Description
In sensitized rats, rotigotine (N-0923) (0.035, 0.1, and 0.35 mg/kg) induced contralateral turning behavior in a dose-dependent manner. In first-time drug-using rats, rotigotine alone or in combination with SCH 39166 reduced the turning behavior compared to the induced rats [1].

The dopamine receptor D2, also known as D2R, is a protein encoded by the DRD2 gene in humans. The dopamine D2 receptor is the main receptor for most antipsychotic drugs. The structure of DRD2 combined with the atypical antipsychotic drug risperidone has been determined.

This gene encodes the D2 subtype of the dopamine receptor, which is coupled to the Gi subtype of the G protein-coupled receptor. This G protein-coupled receptor can inhibit the activity of adenylate cyclase.

In mice, the modulation and exploration of D2R surface expression by neurocalcium sensor 1 (NCS-1) in the dentate gyrus is related to synaptic plasticity and memory formation. A recent study showed that D2R has a potential role in restoring forearm cortical fear memory.

In Drosophila, activation of D2 autoreceptors protects dopamine neurons from MPP+-induced cell death, a toxin that mimics the pathology of Parkinson's disease.
