JWH-098

JWH-098 is a synthetic cannabinoid receptor agonist from the naphthoylindole family. It is the indole 2-methyl derivative of a closely related compound JWH-081, but has markedly different affinity for the CB₁ and CB₂ receptors. While JWH-081 is around tenfold selective for CB₁ over CB₂, in JWH-098 this is reversed, and it is around four times weaker than JWH-081 at CB₁ while being six times more potent at CB₂, giving it a slight selectivity for CB₂ overall. This makes JWH-098 a good example of how methylation of the indole 2-position in the naphthoylindole series tends to increase CB₂ affinity, but often at the expense of CB₁ binding.^[2]

Legal status

In the United States, all CB₁ receptor agonists of the 3-(1-naphthoyl)indole class such as JWH-098 are Schedule I Controlled Substances.^[3]

JWH-098 is illegal in Russia,^[4] Sweden,^[5] and the UK,^[6] although it is unclear whether it has any history of human use.
