Pharmacology
Pharmacodynamics
The drug shows affinity for serotonin receptors, including the serotonin 5-HT1A, 5-HT2A, and 5-HT2C receptors (Ki = 86nM, 659nM, and 801nM, respectively). These affinities were 35-fold, 7-fold, and 10-fold higher than those of mescaline, respectively.
History
2,6-Dichloromescaline was first described in the scientific literature by 1977. Pardanani JH, McLaughlin JL, Kondrat RW, Cooks RG Cactus alkaloids. XXXVI. Mescaline and related compounds from Trichocereus peruvianus Lloydia 40 6 585–590 1977 600028 Its serotonin receptor affinities were determined by David E. Nichols and colleagues, with subsequent disclosure by Daniel Trachsel and colleagues via personal communication in 2013. 2,6-Dichloromescaline has been encountered as a novel designer drug and is said to have been on the recreational market since at least the 1990s. Relatedly, the properties and effects of 2,6-dichloromescaline in humans were described in The Entheogen Review in 1997, claiming a dose of approximately 10mg orally to be robustly active.
