jwh-176 jwh-176 jwh-176 is an analgesic drug which acts as a cannabinoid receptor agonist. its binding affinity at the cb1 receptor is 26.0 nm, making it more potent than thc itself, however jwh-176 is particularly notable in that it is a hydrocarbon containing no heteroatoms. this demonstrates that reasonably high-affinity cannabinoid binding and agonist effects can be produced by compounds with no hydrogen bonding capacity at all, relying merely on van der waals and possibly hydrophobic interactions to bind to the receptor. it was discovered by, and named after, john w. huffman. jwh-176legal statuslegal status uk: class b us: schedule i identifiers iupac name 1-(methyl)naphthalene cas number619294-62-1 ychemspider29341653uniiva60gt97bbcomptox dashboard (epa)dtxsid70692895 chemical and physical dataformulac25h24molar mass324.467 g·mol−13d model (jsmol)interactive image smiles cccccc1=c\c(=c/c2cccc3ccccc32)c2ccccc21 inchi inchi=1s/c25h24/c1-2-3-4-11-21-18-22(25-16-8-7-15-24(21)25)17-20-13-9-12-19-10-5-6-14-23(19)20/h5-10,12-18h,2-4,11h2,1h3/b22-17+key:fpesbqvtvsbbse-oqkwzonesa-n (verify) stereochemistry jwh-176 is the (e)-stereoisomer of 1-(methyl)naphthalene, whereas jwh-171 is the mixture of the (e)- and (z)-isomers. jwh-171 legal status in the united states, cb1 receptor agonists of the 1-(1-naphthylmethylene)indene class such as jwh-176 and jwh-171 are schedule i controlled substances. as of 23 december 2009, any compound structurally derived from 1–(1–naphthylmethyl)indene by substitution at the 3–position of the indene ring by an alkyl group is a class b drug in the united kingdom.
