IC-26 (WIN 1161-3) is an analogue of the opioid analgesic methadone, where the carbonyl group has been replaced by the bioisosteric sulfone group.

Human and animal studies suggest that IC-26 is around the same potency as methadone,[1][2] although other studies have found its activity to be inconsistent between different patients, with consistent opioid activity only being seen at a dose several times that of methadone. IC-26 was assessed for its abuse potantial, but despite being found to have similar potential to methadone for development of dependence[3] it was never placed under international control as an illegal drug.
