O-4310 (1-isopropyl-6-fluoro-psilocin) is a tryptamine derivative developed by Organix Inc which acts as a serotonin receptor agonist. It is claimed to have an EC₅₀ of 5 nM at the 5-HT_2A receptor with 89% efficacy relative to serotonin, and 100-fold selectivity over the 5-HT_2C receptor, while being apparently inactive at the 5-HT_2B antitarget.^[1]^[2]
