25N-N1-Nap
25N-N1-Nap is a phenethylamine derivative from the 25-NB class, which acts as a potent agonist at the 5-HT2A receptor with weaker activity at 5-HT2B and 5-HT2C. 25N-N1-Nap is a biased agonist, producing robust activation of 5-HT2A coupled signaling pathways mediated by beta arrestin 2, but with little or no activation of pathways mediated via Gq. In animal studies it produces antipsychotic-like effects but without producing the head-twitch response associated with psychedelic activity.
