Introduction to 4-Methylmethcathinone

4-Methylmethcathinone (also known as 4-MMC, M-CAT, drone, meow meow, and mephedrone) is a novel entactogen-stimulant substance of the cathinone class. Mephedrone belongs to a group known as the substituted cathinones, which are derivatives of the active ingredient in the khat plant (Catha edulis). It is thought to produce its effects by promoting the release of the neurotransmitters serotonin, dopamine, and norepinephrine in the brain.

Subjective Effects

Subjective effects include stimulation, anxiety suppression, disinhibition, enhanced empathy and sociability, relaxation, increased libido, and euphoria. It is reported to produce a mixture of classic stimulant and entactogenic effects reminiscent of cocaine and MDMA. Mephedrone comes in the form of tablets or powder, which users can swallow, snort, inject, or insert rectally. It is also sometimes sold as MDMA ("molly").

Chemistry

Mephedrone, or 4-methylmethcathinone, is a synthetic molecule of the cathinone family. Cathinones are structurally similar to amphetamines; they contain a phenethylamine core featuring a phenyl ring bound to an amino (NH2) group through an ethyl chain with an additional methyl substitution at Rα. Amphetamines and cathinones are alpha-methylated phenethylamines, with cathinones containing an additional carbonyl group at R1. Mephedrone contains additional methyl substitutions at RN, similarly to MDMA and methamphetamine, and R4 of its phenyl ring.

Pharmacology

Given its chemical structure, mephedrone is likely to act as a releasing agent and a reuptake inhibitor for monoamine neurotransmitters such as dopamine, serotonin, and noradrenaline.

Several articles published near the end of 2011 examined the effects of mephedrone in the brains of rats, as well as its reinforcing potential. Dopamine and serotonin were collected using microdialysis, and increases in these neurotransmitters were measured. Mephedrone administration caused about a 500% increase in dopamine and about a 950% increase in serotonin, reaching peak concentrations at 40 minutes and 20 minutes, respectively, and returning to baseline by 120 minutes after injection.

Analysis of the ratio for dopamine and serotonin indicated that mephedrone was preferentially a serotonin releaser, with a ratio of 1.22:1 (serotonin vs. dopamine). Additionally, half-lives for the decrease in dopamine and serotonin were calculated, showing decay rates of 24.5 minutes and 25.5 minutes.

These findings demonstrate that mephedrone induces a massive increase in both dopamine and serotonin, combined with rapid clearance. This increase in neurotransmitters provides an explanation for the euphoric and stimulating subjective effects associated with this substance.
