Head-twitch response (HTR) studies were conducted in C57BL/6J mice to assess 5-HT2A activation in vivo. All of the compounds acted as full or partial agonists at 5-HT2 subtypes, displaying similar potencies at 5-HT2A and 5-HT2B receptors, but some tryptamines with bulkier N-alkyl groups had lower potency at 5-HT2C receptors and higher 5-HT2B receptor efficacy. In addition, O-acetylation reduced the in vitro 5-HT2A potency of 4-hydroxy-N,N-dialkyltryptamines by about 10- to 20-fold but did not alter agonist efficacy. All of the compoun
