Description:

WARNING: This product is for research use only, not for human or veterinary use.

PSB-KD477 is an Agonist of the Cannabinoid-Activated Orphan G-Protein-Coupled Receptor GPR18. PSB-KD477 displayed significantly higher potency and efficacy than THC, determined in a GPR18-dependent β-arrestin recruitment assay, and were found to be selective versus the CB-sensitive receptors CB1, CB2, and GPR55. Structure-activity relationships were steep, and indole substitution was crucial for biological activity. These first selective agonists, which are structurally distinct from the lipidic agonist(s), will allow target validation studies and may eventually contribute to the deorphanization of GPR18.

More Info
GPR18 is a rhodopsin-like orphan G-protein-coupled receptor (GPCR) that is activated by the natural cannabinoid (CB) Δ9-tetrahydrocannabinol (THC). It is highly expressed in immune cells and represents a promising new drug target.
