JWH 210 is a potent cannabimimetic alkylindole that has been identified in extracts from herbal blends. Structurally and functionally similar alkylindoles are rapidly metabolized by the liver and secreted in the urine, with 5-carboxypentyl metabolites detected in the urine.
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 Ki 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 Ki) at CB1 than both its 4-methyl and 4-n-propyl homologues
JWH-122 (CB1 Ki 0.69 nM) and JWH-182 (CB1 Ki 0.65 nM) respectively, and than the 4-methoxy compound JWH-081 (CB1 Ki 1.2 nM).It was discovered by and named after John W. Huffman.
JWH-210 may be neurotoxic to animals when administered in high doses.
