JWH 302

JWH-302 or (1-pentyl-3-(3-methoxyphenylacetyl)indole) is an analgesic chemical from the phenylacetylindole family, which acts as a cannabinoid agonist with moderate affinity at both the CB₁ and CB₂ receptors. It is a positional isomer of the more common drug JWH-250, though it is slightly less potent with a K_i of 17 nM at CB₁, compared to 11 nM for JWH-250. Because of their identical molecular weight and similar fragmentation patterns, JWH-302 and JWH-250 can be very difficult to distinguish by GC-MS testing.
