The drug is closely related to 2-aminotetralin (2-AT; 2-amino-1,2,3,4-tetrahydronaphthalene), which also substitutes for amphetamine, and is about twice as potent as 2-AT in substituting for amphetamine.[1][2] Other homologous and rigid analogues of amphetamine besides 2-ADN and 2-AT include 2-aminoindane (2-AI), 1-naphthylaminopropane (1-NAP), 2-naphthylaminopropane (2-NAP), 1-phenylpiperazine (1-PP), 6-ABTooltip 6-amino-6,7,8,9-tetrahydro-5H-benzocycloheptene, and 7-ABTooltip 7-amino-6,7,8,9-tetrahydro-5H-benzocycloheptene.[3][2]
