AB-FUBINACA (AMB-FUBINACA) is a psychoactive substance that has EC50 values of 1.8 nM at CB1 and 3.2 nM at CB2, and Ki values of 0.9 nM at CB1 and 23.2 nM at CB2 that function as strong agonists at the cannabinoid receptors. Pfizer first developed it in 2009 as an analgesic drug, but the human application was never pursued. It was found in 2012 in Japan as a constituent in synthetic cannabis mixes, along with a similar chemical called ab fubinaca that had not been previously reported.
