AM-906
AM-906 (part of the AM cannabinoid series) is an analgesic drug which is a cannabinoid agonist. It is conformationally restricted by virtue of the double bond on its side chain, leading an increased affinity for and selectivity between CB and CB receptors. It is a potent and selective agonist for the CB cannabinoid receptor, with a "K" of 0.8 nM at CB and 9.5 nM at CB, a selectivity of almost 12x. The corresponding "E" or trans isomer is AM-905.
