JWH-007 is an analgesic chemical from the naphthoylindole family, which acts as a cannabinoid agonist at both the CB1 and CB2 receptors. It was first reported in 1994 by a group including the noted cannabinoid chemist John W. Huffman.[1][2] It was the most active of the first group of N-alkyl naphoylindoles discovered by the team led by John W Huffman, several years after the family was initially described with the discovery of the N-morpholinylethyl compounds pravadoline (WIN 48,098), JWH-200 (WIN 55,225) and WIN 55,212-2 by the Sterling Winthrop group.[3] Several other N-alkyl substituents were found to be active by Huffman's team including the n-butyl, n-hexyl, 2-heptyl, and cyclohexylethyl groups, but it was subsequently determined that the 2-methyl group on the indole ring is not required for CB1 binding, and tends to increase affinity for CB2 instead.[4][5] Consequently, the 2-desmethyl derivative of JWH-007, JWH-018, has slightly higher binding affinity for CB1, with an optimum binding of 9.00 nM at CB1 and 2.94 nM at CB2, and JWH-007 displayed optimum binding of 9.50 nM at CB1 and 2.94 nM at CB2.[6]
