JWH 193

JWH-193 is a drug from the aminoalkylindole family which acts as a cannabinoid receptor agonist. It was invented by the pharmaceutical company Sanofi-Winthrop in the early 1990s. JWH-193 has a binding affinity at the CB₁ receptor of 6nM, binding around seven times more tightly than the parent compound JWH-200, though with closer to twice the potency of JWH-200 in activity tests. A structural isomer of JWH-193 with the methyl group on the indole ring instead of the naphthoyl ring, was also found to be of similarly increased potency over JWH-200.
