AZD-1940, also known as ART27.13 or NEO-1940, is a drug developed by AstraZeneca, that is a peripherally selective cannabinoid agonist which binds with high affinity to both the CB₁ and CB₂ receptors.^[1] It was developed for the treatment of neuropathic pain, but while it showed good peripheral selectivity in animal studies,^[2] in human clinical trials it failed to show sufficient analgesic efficacy and produced unexpectedly strong side effects associated with central cannabinoid activity, and so was discontinued from further development.^[3]^[4]
