L-759,656 is an analgesic drug that is a cannabinoidagonist. It is a highly selective agonist for the CB2receptor, with selectivity of 414x for CB2 over CB1,[1] although it is still not as selective as newer agents such as HU-308.
It produces some similar effects to other cannabinoid agonists such as analgesia, but with little or no sedative or psychoactive effects due to its weak CB1 activity, and a relatively strong antiinflammatory effect due to its strong activity at CB2.[2][3]
