5-Iodo-2-aminoindane (5-IAI) is a drug which acts as a releasing agent of serotonin, norepinephrine, and dopamine.[1] It was developed in the 1990s by a team led by David E. Nichols at Purdue University.[2] 5-IAI fully substitutes for MDMA in rodents and is a putative entactogen in humans.[2] Unlike related aminoindane derivatives like MDAI and MMAI, 5-IAI causes some serotonergic neurotoxicity in rats, but is substantially less toxic than its corresponding amphetamine homologue pIA, with the damage observed barely reaching statistical significance.[1]
