DOM-AI, also known as 4,7-dimethoxy-5-methyl-2-aminoindane, is a putative serotonergic psychedelic of the 2-aminoindane group related to DOM.^[1]^[2]^[3]^[4] It is a cyclized phenethylamine and the cyclized 2-aminoindane analogue of DOM.^[1]^[2]^[4]

The drug fully substituted for LSD in rodent drug discrimination tests, suggesting that it may have hallucinogenic effects in humans.^[4] However, DOM-AI was much less potent than DOM in these tests, with an ED₅₀Tooltip median effective dose of 2.18 mg/kg, which was approximately 1/15th that of DOM.^[4] Nonetheless, DOM-AI is still active in showing psychedelic-like effects in animals, in contrast to its analogues DOM-AT and DOM-CR.^[4]^[5]

DOM-AI was first described in the scientific literature by David E. Nichols and colleagues in 1974.^[1]^[6]

Other cyclized analogues of DOM and related psychedelics besides DOM-AI, DOM-AT, and DOM-CR include DMCPA, TFMBOX, jimscaline, TCB-2, LPH, and ZC-B.^[7]^[8]^[2]
