MDMB-FUBINACA (also known as MDMB(N)-Bz-F and FUB-MDMB) is an indazole-based synthetic cannabinoid that is a potent agonist for the cannabinoid receptors, with Ki values of 1.14 nM at CB1 and 0.1228 nM at CB2 and EC50 values of 0.2668 nM at CB1 and 0.1411 nM at CB2,[1] and has been sold online as a designer drug.[2][3] Its benzyl analogue (instead of 4-fluorobenzyl) has been reported to be a potent agonist for the CB1 receptor (Ki = 0.14 nM, EC50 = 2.42 nM).[4][5] The structure of MDMB-FUBINACA contains the amino acid, 3-methylvaline[6] or tert-leucine methyl ester.
