Pharmaceutical compound
4-MeO-DET , also known as4-methoxy-N ,N -diethyltryptamine , is achemical compound of thetryptamine and4-methoxytryptamine families related topsilocin (4-HO-DMT).[ 1] It is the 4-methoxy derivative ofdiethyltryptamine (DET), theO -methyl ether 4-HO-DET (ethocin), and apositional isomer of5-MeO-DET .[ 1]
According toAlexander Shulgin in his 1997 bookTiHKAL (Tryptamines I Have Known and Loved ), 4-MeO-DET is completely inactive at doses of up to 30 mgorally orsmoked .[ 1] [ 2] Hence, its dose range is unknown but greater than 30 mg and itsduration is unknown.[ 1] Higher doses were not assessed.[ 1] [ 2]
Analogues of 4-MeO-DET includediethyltryptamine (DET),4-methoxytryptamine (4-MT or 4-MeO-T),4-HO-DET (ethocin),4-AcO-DET (ethacetin),5-MeO-DET ,4-MeO-DMT ,4-MeO-DiPT ,4-MeO-MiPT , and4-methyl-DMT , among others.[ 1] 4-MeO-MiPT is known to be active, producingerotic -enhancing effects but little in the way ofvisuals , whereas 4-MeO-DMT and 4-MeO-DiPT have been found to be active inpreclinical research but have not been tested in humans.[ 1] [ 3] [ 4] [ 5]
Aside from 4-MeO-DET's description inAlexander Shulgin 's 1997 bookTiHKAL (Tryptamines I Have Known and Loved ), 4-MeO-DET does not appear to have been otherwise described in the literature.[ 1]

"The 4-methyl ether of psilocin, 4-MeO-DMT, is especially appealing, in that it is a simple homologue of psilocin and it is quite stable. But the methyl group as an ether link lacks the lability of the phosphate or acetate esters, and it cannot be easily hydrolyzed off to form psilocin. The immediate homologue is 4-MeO-DET which is completely without action either orally or by smoking at dosages up to 30 mgs. The two remaining DMT isomers are with the methoxy at the 6-position (to give 6-MeO-DMT originally thought to be a minor alkaloid in B. caapi) and at the 7-position (to give 7-MeO-DMT which was observed as a minor impurity in the preparation of 7-MeO-MIPT)."^a b "PiHKAL info" (PDF) .^ Kozell LB, Eshleman AJ, Swanson TL, Bloom SH, Wolfrum KM, Schmachtenberg JL, et al.

The respective ED50 values (µmoles/kg., i.p.) for disrupting size-discrimination performance in monkeys and swimming ability in rodents are 18·9 and 2·9 (Uyeno, 1969) and 20·1 and 8·7 (Uyeno, 1971). Perhaps these results reflect the differing lipid solubilities of the compounds, because bufotenin, 5-MeO-DMT, psilocin, and compound 4.26 have respective chloroform-water partition coefficients of 0·06, 3·30, 5·52, and 2·28 (Gessner and others, 1968). Clearly, little advantage in physico-chemical characteristics is gained by methylation of the 4-hydroxy group of psilocin compared to the 5-hydroxy group of bufotenin. ^ Nichols DE, Glennon RA (1984)."Medicinal Chemistry and Structure-Activity Relationships of Hallucinogens" .
