Chemical structure of CP 55,940

CP 55,940, also written as CP55940, CP55,940, CP-55940, CP-55,940, and CP 55940, is a cannabinoid which mimics the effects of naturally occurring THC (the psychoactive compound found in marijuana). CP 55,940 was created by Pfizer in 1974 and was never marketed because of its highly psychoactive nature. It is currently used by scientists to study cannabinoid effects in biology. Some effects that have been noted are a greatly decreased rates of lever pressing in exposed mice, and a greater reaction to opiates in exposed mice. CP-55940 is 40 times more potent than Δ9-THC, and fully antagonized by rimonabant (SR141716A) (Life Sci 1996;58:1239-47; last update 010106).
