4-HO-NALT

4-Hydroxy-N-allyltryptamine (4-HO-NALT) is a tryptamine derivative developed by modification of norpsilocin (4-HO-NMT). It produces a head-twitch response in mice consistent with psychedelic-like activity, as do the corresponding ethyl, propyl, isopropyl and benzyl derivatives (4-HO-NET, 4-HO-NPT, 4-HO-NiPT and 4-HO-NBnT), but the bulkier t-butyl and cyclohexyl derivatives are inactive.
