GW842166 is a pyrimidine cannabinoid 2 (CB2) receptor agonist that was being developed by GlaxoSmithKline for the treatment of inflammatory pain. 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. GW842166 shows similar potency and efficacy for rat and human recombinant CB2 receptors with EC50 of 91 nM and 63nM, respectively. GW842166 is in Phase 2 trial.
