(±)-Vesamicol is an acetylcholine (ACh) uptake inhibitor (IC50 = 40 nM) and neuromuscular blocking agent.1,2 It binds to the vesamicol receptor (Ki = 2 nM), as well as sigma non-opioid intracellular receptor 1 (σ1-receptor) and sigma intracellular receptor 2 (σ2-receptor; Kis = 26 and 34 nM, respectively).3 (±)-Vesamicol (150 µg/kg) inhibits electrically induced maximal twitches of tibialis anterior muscles in anesthetized cats.2 It induces transient flaccid paralysis in conscious mice when administered intravenously or orally (ED50s = 2.7 and 35.5 mg/kg, respectively). Intracerebroventricular administration of (±)-vesamicol (80 or 100 µg/animal) decreases rapid eye movement (REM) sleep frequency and duration in rats.4
