Pharmaceutical compound
N -Hydroxy-DOM , also known as 4-methyl-2,5-dimethoxy-N -hydroxyamphetamine or as DOM-OH , is a possible psychedelic drug of the phenethylamine , amphetamine , and DOx families related to DOM .[ 1] [ 2] [ 3] It is the N -hydroxy derivative of DOM.[ 1] [ 2] [ 3] The drug was not included nor mentioned by Alexander Shulgin in his 1991 book PiHKAL (Phenethylamines I Have Known and Loved ) and its properties and effects in humans are unknown.[ 4] [ 3] N -Hydroxy-DOM was reported to produce DOM-like behavioral and physiological effects in rats, including pupil dilation and hypolocomotion among others, but was 6-fold less potent than DOM in this species.[ 1] [ 5] It also appears to be a metabolite of DOM formed by the liver in rabbits.[ 2] Other N -hydroxy derivatives of phenethylamines such as the HOT-x series like HOT-2 (N -hydroxyl-2C-T-2) as well as MDOH (N -hydroxy-MDA) may act as prodrugs of their N -unsubstituted analogues .[ 4] The chemical synthesis of N -hydroxy-DOM has been described.[ 5] N -Hydroxy-DOM was first described in the scientific literature by Ronald Coutts and Jerry Malicky by 1973.[ 5] [ 6]

Bibcode :1981JPhmS..70..839N . doi :10.1002/jps.2600700802 . PMID 7031221 . One other active substitution on nitrogen is the N-hydroxy group. N-Hydroxylation of III gives a compound possessing clinical activity (66). Coutts and Malicky (72) evaluated several congeners of II. One, the N-hydroxy derivative (XXI), elicited behavioral effects in rats but at about six times the dosage required for II.
