The analogue with a 1-butyl substitution on the indazole ring rather than 1-benzyl has also been sold as a designer drug under the name ADB-BINACA, but is now more commonly referred to as ADB-BUTINACA to avoid confusion with the benzyl compound.[4][5][6][7][8] It is a similarly potent CB1 agonist, with a binding affinity of 0.29nM for CB1 and 0.91nM for CB2, and an EC50 of 6.36 nM for CB1.[9][10]
