It is highly selective for the cannabinoid-2 receptor (CB2 receptor) subtype, with a selectivity more than 5,000 times greater for the CB2 receptor than the CB1 receptor. The synthesis and characterization of<unk>  took place in the laboratory of Raphael Mechoulam at the Hebrew University of Jerusalem (the<unk>  in<unk>  in the late 1990s. The pinene dimethoxy-DMH-CBD derivative<unk>  was identified as a potent peripheral CB2-selective agonist in in vitro and animal studies in 1990 and 1999.
