5-Methoxy-7,N,N-trimethyltryptamine

DMT and 5-MeO-DMT, but compounds with larger 7-position substituents such as 7-ethyl-DMT and 7-bromo-DMT did not produce psychedelic-appropriate responding despite high 5-HT₂ receptor binding affinity, suggesting these may be antagonists or weak partial agonists for the 5-HT₂ receptors.^[4] The related compound 7-MeO-MiPT (cf. 5-MeO-MiPT) was also found to be inactive, suggesting that the 7-position has poor tolerance for bulky groups at this position, at least if agonist activity is desired.^[5]
