JWH-210

JWH-210 is an analgesic chemical from the naphthoylindole family, which acts as a potent cannabinoid agonist at both the CB₁ and CB₂ receptors, with K_i values of 0.46 nM at CB₁ and 0.69 nM at CB₂. It is one of the most potent 4-substituted naphthoyl derivatives in the naphthoylindole series, having a higher binding affinity (i.e. lower K_i) at CB₁ than both its 4-methyl and 4-n-propyl homologues JWH-122 (CB₁ K_i 0.69 nM) and JWH-182 (CB₁ K_i 0.65 nM) respectively, and than the 4-methoxy compound JWH-081 (CB₁ K_i 1.2 nM).[2] It was discovered by and named after John W. Huffman.

JWH-210 may be neurotoxic to animals when administered in high doses.[3]

Legal status

In the United States, all CB₁ receptor agonists of the 3-(1-naphthoyl)indole class such as JWH-210 are Schedule I Controlled Substances.[4]

JWH-210 and JWH-122 were banned in Sweden on 1 October 2010 as hazardous goods harmful to health, after being identified as ingredients in "herbal" synthetic cannabis products.[5][6] The substances JWH-210, JWH-122 and JWH-203 were classified as illegal drugs by the Swedish government as of 1 September 2011.[7]

As of October 2015 JWH-210 is a controlled substance in China.[8]
