SNC-80

SNC-80 is an opioid analgesic drug that selectively activates μ–δ opioid receptor heteromers[1] and is used in scientific research.[2] It was discovered in 1994.[3]

SNC-80 was the first non-peptide drug developed that was regarded as a highly selective agonist for the δ-opioid receptor.[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.
