  • JWH 018-4(methylpiperazine)

JWH 018 (Item No. 10900) is a potent synthetic cannabinoid (CB) that avidly binds both the central CB1 receptor and the peripheral CB2 receptor (Kis = 9.0 and 2.9 nM, respectively).1 Structurally, JWH 018 is an aminoalkylindole with a naphthoyl group. Mepirapim is an analog of JWH 018 that has been identified in herbal blends in Japan.2 It differs from JWH 018 by having a 4-methylpiperazine group in place of the naphthyl group. The physiological and toxicological properties of this compound are unknown. This product is for forensic and research applications.
