Pharmacology
JWH-046 belongs to the 1-alkyl-3-(1-naphthoyl)indoles, a series studied by John W. Huffman at Clemson University to improve CB2 ligands and to establish the structure-activity relationship at CB1 and CB2. It carries a propyl on the indole nitrogen, a methyl at position 2 and a naphthyl methylated at position 7. The published affinities are about 344 nM at rat CB1 and 16.0 nM at human CB2, according to De Freitas et al. (2009). No functional measurement specific to this compound, no pharmacokinetic data, and no human or toxicological data were found in the consulted sources. In France, it is controlled as a narcotic through a generic clause, not by its name.

History
- Source
- Fully synthetic molecule. No consulted source describes it in a plant or in any living organism: it is a synthetic compound published within research on cannabinoid receptors.
Origin (pharmaceutical research → illicit market)
No biosynthetic pathway: the molecule is produced by no living organism and comes solely from organic synthesis, by acylation of the indole at position 3.
Legal framework
- European Union
No harmonised control measure at European Union level was identified for this compound in the consulted sources: control falls under the national law of the member states. It is also absent from the INCB Green List 2026, which lists substances under the international conventions.
- France
Not named in the ANSM consolidated list of 16 February 2026, but subject to the narcotics regime through a generic clause. Annex IV of this list defines the indol-3-yl methanone family: an alkyl-type substituent on the indole nitrogen, and a naphthyl group, substituted or not, on the methanone carbon. JWH-046 meets these conditions: its nitrogen carries a propyl and its methanone carries a naphthyl methylated at position 7, which the definition allows. JWH-015, which differs only by this methyl, is cited by name in the same annex. Production, possession, transfer and use fall under the criminal regime for narcotics.
