| Siramesine
Siramesine (Lu 28-179) is a potent sigma-2 receptor agonist. Siramesine has a subnanomolar affinity for sigma-2 receptors (IC50=0.12 nM) and exhibits a 140-fold selectivity for sigma-2 receptors over sigma-1 receptors (IC50=17 nM). Siramesine triggers cell death through destabilisation of mitochondria, but not lysosomes. |

| Pentoxyverine Citrate
Pentoxyverine citrate is an orally active sigma-1 receptor agonist with Ki values of 41 nM for σ1, 894 nM for σ2, and 75 nM for σ1 in guinea pig brain membranes.Pentoxyverine citrate is also a muscarinic antagonist. |
| Cutamesine dihydrochloride
Cutamesine dihydrochloride (SA4503 dihydrochloride; AGY94806 dihydrochloride) is a novel and selective opioid sigma1 receptor agonist with IC50 of 17.4 nM. |
| Veratramine
Veratramine (NSC17821; NSC23880) is a signal transduction inhibitor that acts on tumors. Veratramine induces autophagic apoptosis of tumor cells, arrests the cell cycle at the G0/G1 phase, and inhibits epithelial-mesenchymal transition (EMT)-related proteins to reduce tumor migration. Veratramine has anti-tumor proliferation, apoptosis induction, anti-inflammatory and neuroprotective activities. |
