ADB-FUBINACA is a designer drug identified in synthetic cannabis blends in Japan in 2013. The (S) enantiomer of ADB-FUBINACA is claimed in Pfizer patent WO 2009/106982 with a Ki value of 0.36nM at CB1. ADB-FUBINACA features a carboxamide group at the 3-indazole position like SDB-001 and STS-135. ADB-FUBINACA appears to be the product of rational drug design since it differs from AB-FUBINACA only by the replacement of the iso-propyl group with a tert-butyl group.
