DM-506 (Ibogaminalog) is a drug first invented in the 1960s,^[1] which acts as both a partial agonist at the 5-HT_2A receptor, and a negative allosteric modulator at the α7 and α9α10 nicotinic acetylcholine receptors. It can be regarded as a structurally simplified derivative of ibogaine and has been researched both for anti-addictive effects and for the treatment of neuropathic pain.^[2]^[3]^[4]^[5]^[6]
