Ethocybin also known as 4-phosphoryloxy-N,N-diethyltryptamine (4-PO-DET) or as CEY-19, is a psychedelic drug of the tryptamine and 4-hydroxytryptamine families related to the psilocybin-containing mushroom alkaloid psilocybin. [1] It is assumed to act as a prodrug of 4-HO-DET (CZ-74) analogously to how psilocybin (4-PO-DMT) acts as a prodrug of psilocin (4-HO-DMT). [1] [6] The drug was first described in the literature by Albert Hofmann and colleagues at Sandoz by 1963. [7] [8]

Pharmacology

Ethocybin may be dephosphorylated in vivo to 4-HO-DET (ethocin), analogously to how psilocybin (4-PO-DMT) is metabolized to psilocin (4-HO-DMT). [9] This chemical reaction takes place under strongly acidic conditions or enzymatically by phosphatases in the body. 4-HO-DET acts as a partial agonist of the serotonin 5-HT2A receptor. [10] [11]

History

Albert Hofmann and colleagues working at Sandoz were the first to synthesize and describe ethocybin (CEY-19) along with 4-HO-DET (CZ-74), which shortly followed his discovery of psilocin and psilocybin. [7] [8] They first described the drug in a patent by 1963. [7] [8] Along with 4-HO-DET, ethocybin was one of the earliest structurally modified or synthetic psychedelic tryptamines to be developed. [2] [5]

Society and culture

United States

Ethocybin is not controlled in the United States, but possession or sale may be considered illegal under the Federal Analog Act.[ citation needed ]

Research

Ethocybin, under the code name CEY-19 and along with 4-HO-DET (CZ-74), has been studied in psychedelic-assisted psychotherapy. [4] [1] [8]

Both CZ-74 and its O-phosphoryl derivative CEY 19 (17) were studied in humans. Qualitatively, these compounds were very similar to psilocin and psilocybin, respectively, but had somewhat reduced durations of action (Leuner and Baer 1965).

Although the N-dealkylated homologs are as yet untested clinically, the N,N-diethyl homologs of psilocybin and of psilocin have been studied in man (Leunder and Baer, 1965). These compounds [CEY-19, (XXXIII); CZ-74, (XXXIV)] in dosages of from 5 to 20 mg appear to resemble psilocybin in the qualitative nature of their action but to be of shorter duration. Maximum effects are obtained in an hour, and 2 hours later the subject is for the most part recovered, thus providing a valuable time course for psychiatric therapy.

Some European therapists experimented with shorter-acting psilocybin derivatives such as CZ-74 (4-hydroxy-N,N-diethyltryptamine, also known as 4-HO-DET; Baer, 1967; Shulgin & Shulgin, 2014), which has a duration of 4—6 hours and is phenomenologically similar to LSD; CEY-19 (phosphoryloxy-N,N-diethyltryptamine, also known as 4-PO-DET or ethocybin), which has a duration of 2—4 hours and is also similar to LSD, and the mescaline derivative 2-CD (2,5-dimethoxy-4-methylphenethylamine; Schlichting, 1989). Therapists in the United States experimented with the short-acting dipropyltrytamine (DP T) in psycholytic therapy (Soskin, 1975; Soskin, Grof, & Richards, 1973), as well as in psychedelic therapy (Richards, Rhead, DiLeo, Yensen, & Kurland, 1977).

Sandoz began manufacturing and distributing pure synthetic psilocybin pills (under the name Indocybin) to curious physicians and researchers around the world and would do so until recalling the drug in 1965 due to a growing political backlash in the United States (Hofmann, 2005). Sandoz also produced two synthetic drugs derived from mushroom-extracted psilocybin, CZ-74 (4-hydroxy-N,N-diethyltryptamine) and CEY-19 (4-phosphoryloxy-N,N-diethyltryptamine), both of which are shorter (approximately 3 hours in duration) acting than psilocybin (Baer, 1967).
