SNC-80 is an opioid analgesic drug used in scientific research.[1] It was invented in 1994.[2]

SNC-80 was the first non-peptide drug developed that is a highly selective agonist for the δ-opioid receptor.[3][4]

It has been shown to produce useful analgesic,[5] antidepressant[6] and anxiolytic effects in animal studies,[7][8] but its usefulness is limited by producing convulsions at high doses,[9] and so SNC-80 is not used medically, although it is a useful drug in scientific research.
