GW-842,166X is a drug which acts as a potent and selective cannabinoid CB2 receptor agonist, with a novel chemical structure based on a pyrimidine core. It has potent analgesic, anti-inflammatory and anti-hyperalgesic actions in animal models, but without cannabis-like behavioural effects due to its extremely low affinity for the CB1 receptor.[1][2] GSK brought this compound for into 4 clinical trials, two of them related to pain management[3][4] and the other two related to bio-distributions.[5][6] The trials were either withdrawn or completed without posting result.
