Carbetapentane (Pentoxyverine, CB) is an antitussive anticonvulsant nonselective sigma-1 (σ1) agonist.

σ1 Receptor antagonist-1 is a highly potent and selective sigma 1 receptor antagonist (pKi=10.28). σ1 Receptor antagonist-1 inhibits cell growth, arrests cell cycle at G0/G1 phase and induces apoptosis of MCF-7/ADR cells.

BMY-14802 hydrochloride (BMY-14802-1) is a selective and orally active sigma receptor antagonist with an IC50 of 112 nM. BMY-14802 hydrochloride is also a 5-HT1A and adrenergic α1 receptors agonist. BMY-14802 hydrochloride has antipsychotic effects.

Rimcazole (BW 234U) dihydrochloride is a carbazole derivative that acts in part as a sigma (σ) receptor antagonist. Rimcazole dihydrochloride also binds with moderate affinity to the dopamine transporter and inhibit dopamine uptake. Rimcazole dihydrochloride can attenuate cocaine-induced locomotor activity and sensitization. Rimcazole dihydrochloride also can be used for the research of cancer.

CM398 is a highly selective, orally active sigma-2 receptor ligand (Ki=0.43 nM), with high sigma-1/sigma-2 selectivity rato (1000-fold). CM398 shows notable affinity for dopamine (Ki=32.90 nM) and serotonin transporters (Ki=244.2 nM). CM398 shows promising anti-inflammatory analgesic effects in the formalin model of inflammatory pain in mice.

Sigma-LIGAND-1 hydrochloride is a selective sigma receptor ligand with an IC50s of 16 nM, 19 nM at the DTG site and the PPP site, respectively. Sigma-LIGAND-1 hydrochloride has a Ki of 4000 nM at the dopamine D2 receptor.

Opipramol (Ensidon) is an atypical tricyclic antidepressant (TCA). Opipramol acts primarily as a sigma (σ) receptor agonist and can potently interact with sigma recognition sites with a Ki value of 50 nM. Opipramol can be used for the research of generalized anxiety disorder (GAD).

AZ-66 is a highly potent S1R/S2R antagonist with Ki of 0.31/1.76 nM, respectively.
