PG - 497-505 LID - 10.1097/FBP.0000000000000237 [doi] AB - 5,6-Methylenedioxy-2-aminoindane (MDAI) has become a common substitute for (+/-)-3,4-methylenedioxymethamphetamine (MDMA) in Ecstasy. MDAI is known to produce MDMA-like discriminative stimulus effects, but it is not known whether MDAI has psychostimulant or hallucinogen-like effects. MDAI was tested for locomotor stimulant effects in mice and subsequently for discriminative stimulus effects in rats trained to discriminate cocaine (10 mg/kg, intraperitoneally), methamphetamine (1 mg/kg, intraperitoneally), +/-MDMA (1.5 mg/kg, intraperitoneally), or (-)-2,5-dimethoxy-4-methylamphetamine hydrochloride (0.5 mg/kg, intraperitoneally) from saline. The ability of MDAI to produce conditioned place preference was also tested in mice. MDAI (3 to 30 mg/kg) depressed locomotor activity from 10 to 60 min. A rebound stimulant effect was observed at 1 to 3.5 h following 30 mg/kg. Lethality occurred in 8/8 mice following 100 mg/kg MDAI. Similarly, MDMA depressed locomotor activity immediately following the administration of 0.25 mg/kg and stimulant effects were observed 50-70 min following the administration of 0.5 and 1 mg/kg. MDAI fully substituted for the discriminative stimulus effects of MDMA (2.5 mg/kg), (-)-2,5-dimethoxy-4-methylamphetamine hydrochloride (5 mg/kg), and cocaine (7.5 mg/kg), but produced only 73% methamphetamine-appropriate responding at a dose that suppressed responding (7.5 mg/kg). MDAI produced tremors at 10 mg/kg in one methamphetamine-trained rat. MDAI produced conditioned place preference from 0.3 to 10 mg/kg. The effects of MDAI on locomotor activity and drug discrimination were similar to those produced by MDMA, having both psychostimulant-like and hallucinogen-like effects; thus, MDAI may have similar abuse potential as MDMA.
