DMCM

DMCM (methyl 6,7-dimethoxy-4-ethyl-β-carboline-3-carboxylate) is a drug from the β-carboline family. It acts as a negative allosteric modulator of GABAA receptors, meaning that it causes the opposite effects to the benzodiazepine class of drugs. As such, DMCM has anxiogenic and convulsant properties,[1] and is used in scientific research to induce anxiety so that new anxiolytic medications can be tested,[2] and to produce convulsions so that anticonvulsant medications can be tested.[3][4][5] It has also been shown to produce analgesic effects in animals, thought to be because it produces panic which reduces the perception of pain.[6]
