BDPC

Not to be confused with bromperidol or bromadoline.

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 arylcyclohexylamine chemical structure. It was developed by Daniel Lednicer at Upjohn in the 1970s.^[1] Initial studies estimated that it was around 10,000 times the potency 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]
