JWH-200

JWH-200 (WIN 55,225) is an analgesic chemical from the aminoalkylindole family that acts as a cannabinoid receptor agonist. Its binding affinity, Ki at the CB1 receptor is 42 nM, around the same as that of THC, but its analgesic potency in vivo was higher than that of other analogues with stronger CB1 binding affinity in vitro, around 3 times that of THC but with less sedative effect, most likely reflecting favourable pharmacokinetic characteristics. It was discovered in 1991 by Sterling Drug as a potential analgesic following the earlier identification of related compounds such as pravadoline and WIN 55,212-2.
