Cannabinoid Receptor

Cannabinoid receptors are currently classified into three groups: central (CB1), peripheral (CB2) and GPR55, all of which are G-protein-coupled. CB1 receptors are primarily located at central and peripheral nerve terminals. CB2 receptors are predominantly expressed in non-neuronal tissues, particularly immune cells, where they modulate cytokine release and cell migration. Recent reports have suggested that CB2 receptors may also be expressed in the CNS. GPR55 receptors are non-CB1/CB2 receptors that exhibit affinity for endogenous, plant and synthetic cannabinoids. Endogenous ligands for cannabinoid receptors have been discovered, including anandamide and 2-arachidonylglycerol.

  • HY-172808
    BNS808
    Antagonist
    BNS808 is an orally active and selective cannabinoid-1 receptor (CB1R) antagonist (IC50 = 0.8 nM) with notable CB2R selectivity and minimal brain penetration. BNS808 is studied in research on obesity and its associated metabolic complications, such as metabolic dysfunctional-associated steatotic liver disease (MASLD). BNS808 has reduced free drug availability for CNS entry, enhancing safety and minimizing drug-drug interactions through high plasma binding.
