Methylone (3, 4-Methylenedioxy-N-methylcathinone), a β-keto analog of 3,4-methylenedioxy-N-methylamphetamine (MDMA) is a stimulant and psychoactive drug. Methylone is a popular drug of abuse that strongly increases the release of the three monoamines: dopamine, serotonin (5-HT) and norepinephrine. In addition, methylone inhibits plasma membrane catecholamine transporters but only weakly inhibit the vesicle transporter. In April 2013, methylone was listed in the Schedule 1 substance under the Controlled Substances Act.
