    Beatrice, also known as 4-methyl-2,5-dimethoxy-N-methylamphetamine or as N-methyl-DOM, MDOM, or MDO-D, is a lesser-known psychoactive drug of the phenethylamine, amphetamine, and DOx families.[1][2] It is a substituted methamphetamine and a homolog of 2,5-dimethoxy-4-methylamphetamine (DOM).[1][2] Beatrice was first synthesized by Alexander Shulgin.[1][2]

    Use and effects

    In Shulgin's book PiHKAL, the minimum dosage is listed as 30 mg, and the duration is listed as 6 to 10 hours.[1][2] Beatrice produces a vague feeling of openness and receptiveness, and causes a stimulative effect.[1] It also causes diarrhea.[1]

    Pharmacology

    Beatrice shows affinity for serotonin receptors.[3][4] Its affinities (Ki) were 415 nM for the 5-HT2 receptor and 3,870 nM for the 5-HT1 receptor.[3][4] The affinity of Beatrice for the serotonin 5-HT2 receptor was about 4-fold lower than that of DOM.[3][4] Functional activities were not reported.[3][4]

    Analogues

    Analogues of Beatrice include N-methyl-DOI (N-Me-DOI), N-methyl-DOB, and IDNNA (N,N-dimethyl-DOI).[1][2][5] N-Methyl-DOI is a potent agonist of the serotonin 5-HT2A receptor similarly to DOI, but with several-fold reduced potency and slightly reduced efficacy.[5]

    Society and culture

    In the United States, Beatrice is a Schedule I isomer of DOET.
