JWH 200 is an aminoalkylindole that acts as a cannabinoid (CB) receptor ligand. It binds to the CB1 receptor with high-affinity (IC50 = 7.8-42 nM).1,2 The effects of JWH 200 in locomotor activity, tail-flick latency, hypothermia, and ring-immobility tests are comparable or superior to Δ9-THC or WIN-55,212.3 It potently inhibits the contraction of electrically-stimulated murine vas deferens (IC50 = 3.7-6.0 nM).4,5
