CP 47,497 is a bicyclic CB analog with potent analgesic activity. It is comparable or more potent than Δ9-tetrahydrocannabinol in analgesic, motor depressant, anticonvulsant, and hypothermic effects in mice, rats, and dogs. The dextrorotatory enantiomer, (+)-CP 47,497 avidly binds the CB1 receptor (Ki = 4.15 nM).
