5-HO-DET, or5-hydroxy-DET, also known as5-hydroxy-N,N-diethyltryptamine, is aserotonin receptor modulator of thetryptamine and5-hydroxytryptamine families related to thepsychedelic drugbufotenin (5-HO-DMT).[1][2][3] It is thederivative of bufotenin in which theN,N-dimethylgroups have been replaced withN,N-diethyl groups.[1][2] The drug is also theN,N-diethyl derivative ofserotonin (5-hydroxytryptamine) and the 5-hydroxy derivative ofdiethyltryptamine (DET).[1][2]

Pharmacology

[edit]

Pharmacodynamics

[edit]

5-HO-DET shows relatively lowpotency in terms of psychedelic-like behavioral effects in theconditioned avoidance response test in rodents.[1][2] It has been suggested that this might be due to 5-HO-DET having poorlipophilicity andblood–brain barrierpermeability analogously to bufotenin.[1][2] However, 5-HO-DET has significantly greaterlipophilicity than bufotenin owing to its ethyl instead of methyl groups (predictedlog P = 1.9 and 1.2, respectively).[4][5] 5-HO-DET has been assessed and found to show highaffinity for the serotonin5-HT1E and5-HT1F receptors.[3]

History
