C-8813 (thiobromadol) is a potent μ-opioid receptor agonist with a distinctive chemical structure which is not closely related to other established families of opioid drugs. The trans-isomer was found to be around 591 times more potent than morphine in animal studies.^[1] The same study assigned a potency of 504 times that of morphine to the related compound BDPC.

C-8813 is claimed to be similarly potent at the δ-opioid receptor, which antagonizes the mu depression of breathing, presumably making the drug safer.^[1]

C-8813 has never been used in humans.
