Mepirapim (original) (raw)

MEPIRAPIM is an indole-based cannabinoid which differs from JWH-018 by having a 4-methylpiperazine group in place of the naphthyl group and has been used as an active ingredient in synthetic cannabis products. It was first identified in Japan in 2013, alongside FUBIMINA. MEPIRAPIM acts as a T-type calcium channel inhibitor and is only minimally active at the central CB1 receptor.
