25N-NBPh
Chemical compound
25N-NBPh (NBPh-2C-N) 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-NBPh is a biased agonist, producing robust activation of 5-HT2A coupled signalling pathways mediated by beta arrestin 2, but with only slight activation of pathways mediated via Gq. In animal studies it produces a modest head-twitch response when administered by itself, but blocks the effects of the fully active psychedelic DOI. [1][2][3]
