The N,N-dimethyl homologue of DOI was called IDNNA (2,5-dimethoxy-N,N-dimethyl-4-iodoamphetamine) and, although not active at levels where DOI would be, it led to an extensive series of some 15 mono- and di-N-alkylated amines related to DOI. They were prepared for studies of 131I labelled compounds for rat pharmacology (and eventual 122I PET scanning agents for human studies) but none of them had been clinically explored.
