Dopamine D2 Receptor Antagonist-1 functions as a negative allosteric modulator (NAM) of the dopamine D2 receptor (D2R), demonstrating sub-millimolar affinity.

Tiospirone (BMY 13859-1 free base) is a 5-HT2 receptor antagonist and dopamine blocker that inhibits D2, 5-HT1a, 5-HT7, and sigma receptors.Tiospirone is used in the study of neurological disorders such as schizophrenia.

Perphenazine dihydrochloride is an orally active dopamine receptor and histamine-1 receptor antagonist that acts on D2 (Ki: 0.56 nM), D3 (Ki: 0.43 nM), and 5-HT2A (Ki: 0.6 nM) receptors, and also binds Alpha-1A adrenergic receptors. It can induce apoptosis, inhibit cancer cell proliferation, and is used to study psychiatric disorders, cancer, and inflammation.

Pridopidine (FR310826), a dopamine (DA) stabilizer, acts as a low affinity dopamine D2 receptor (D2R) antagonist, improves motor performance and shows neuroprotective effects in Huntington disease R6/2 mouse model.

D3/5-HT receptor modulator-1 (compound 5i) is a selective antagonist of the dopamine D3 and 5-HT2A receptors, and a partial agonist at the 5-HT1A receptor. It exhibits Ki values of 4.5 nM, 11.9 nM, and 15.3 nM for the dopamine D3, 5-HT2A, and 5-HT1A receptors respectively. The compound shows lower affinity for the dopamine D2 receptor, 5-HT2C receptor, and hERG channel. D3/5-HT receptor modulator-1 possesses atypical antipsychotic properties.

BGC20-761 is a selective 5-HT6 and dopamine receptor antagonist (human receptor K i values: 5-HT6 (20 nM), 5-HT2A (69 nM), D2 (140 nM)), and a tryptamine analog with a high affinity for 5-HT(6) receptors, that can enhance long-term memory, with potential utility as an antipsychotic agent [1].

Tiapride is an atypical neuroleptic agent without propensity for causing catalepsy and sedation. Tiapride is a selective antagonist of dopamine D2-receptor with IC 50 values of 1440, 45.8, >100, and 11.7 μM for D1; D2; D3; D4, respectively [1].

Thioridazine is a chemical compound characterized by its potent anti-psychotic and anti-anxiety activities. As an antagonist of the dopamine receptor D2 family proteins, it exhibits a strong inhibitory effect on the PI3K-Akt-mTOR signaling pathways, resulting in anti-angiogenic effects. It also demonstrates significant antiproliferative and apoptosis induction effects in a diverse range of cancer cells, specifically targeting cancer stem cells (CSCs) [1] [2] [3] [4].

6-Hydroxy Buspirone, an active metabolite of the anxiolytic compound buspirone, is produced via the cytochrome P450 (CYP) isoform CYP3A4. This compound exhibits affinity for the serotonin (5-HT) receptor subtype 5-HT1A, demonstrating efficacy in the rat hippocampus and dorsal raphe with half-maximal effective concentrations (EC50s) of 4 and 1 µM, respectively. Furthermore, 6-Hydroxy Buspirone acts as a potent antagonist against dopamine D2, D3, and D4 receptors with half-maximal inhibitory concentrations (IC50s) of 3.1, 4.9, and 0.85 µM, respectively, and inhibits the organic cation transporters 1 (OCT1), OCT2, and OCT3 in S2 proximal tubule cells expressing human transporters, showcasing a concentration-dependent mechanism.

BP 897 (2-Naphthalenecarboxamide, N-[4-[4-(2-methoxyphenyl)-1-piperazinyl]butyl]-) is a potent and selective dopamine D3 receptor agonist, and a weak dopamine D2 receptor antagonist, with Kis of 0.92 nM and 61 nM for D3 and D2 receptors, and shows low affinities at D1 and D4 receptors (Kis, 3 and 0.3 μM, respectively).

Pimozide-d4-1 is an antagonist of dopamine receptors, exhibiting Ki values of 1.4 nM, 2.5 nM, and 588 nM for dopamine D2, D3, and D1 receptors, respectively, and also shows high affinity for the α1-adrenoceptor with a Ki value of 39 nM; additionally, Pimozide acts as an inhibitor of STAT3 and STAT5.

Sulpiride-d5 is a deuterated compound of Sulpiride. Sulpiride has a CAS number of 15676-16-1. Sulpiride is a dopamine D2-receptor antagonist, used therapeutically as an antidepressant, antipsychotic, and as a digestive aid.
