5F-AMB (also known as 5F-MMB-PINACA and 5F-AMB-PINACA) is an indazole-based synthetic cannabinoid from the indazole-3-carboxamide family. Thus, it is used as an active ingredient in synthetic cannabis products. It was first identified in Japan in early 2014.
Although only very little pharmacological information about pinaca-mmb itself exists. However, its 4-cyanobutyl analogue (instead of 5-fluoropentyl) has been reported to be a potent agonist for the CB1 receptor.
