SNC-80
SNC-80 is an opioid analgesic compound that selectively activates μ–δ opioid receptor heteromers and is used primarily in scientific research. Discovered in 1994, SNC-80 was a pioneering non-peptide compound regarded as a highly selective agonist for the δ-opioid receptor.
SNC-80 was the first non-peptide compound developed that was regarded as a highly selective agonist for the Delta [opioid receptor|δ-opioid] receptor.
It has been shown to produce useful analgesic, antidepressant and anxiolytic effects in animal studies, but its usefulness is limited by producing convulsions at high doses, and so SNC-80 is not used medically, although it is a useful compound in scientific research.
