The new compounds have been tested for their affinity and functionality regarding CB1 and CB2 cannabinoid and µ opioid receptors. In [35S]-GTPγS (guanosine 5’-O-[gamma-thio]triphosphate) binding assays from the post-mortem human frontal cortex, they proved to be CB1 cannabinoid antagonists and µ opioid antagonists. Interestingly, in vivo, the new compounds exhibited a significant dual antagonist action on the endocannabinoid and opioid systems. Keywords: fentanyl, rimonabant, cannabinoid, opioid, behavioral assays
