BDPC (systematic name 4-(4-bromophenyl)-4-(dimethylamino)-1-(2-phenylethyl)cyclohexanol; also known as bromadol) is a potent fully synthetic opioid with a distinctive arylcyclohexylaminechemical structure. It was developed by Daniel Lednicer at Upjohn in the 1970s.[1] Initial studies estimated that it was around 10,000 times the strength of morphine in animal models.[2] However, later studies using more modern techniques assigned a value of 504 times the potency of morphine for the more active trans-isomer.[3] This drug was first seized along with three kilograms of acetylfentanyl in an April 25, 2013 police action in Montreal, Canada,[4] and has reportedly continued to be available on the designer drug market internationally.[5][6] Analogues where the para-bromine is replaced by chlorine or a methyl group retain similar activity, while the meta-hydroxyl derivative demonstrated robust antagonist activity.[7][8]
