(A) Comparison of docking poses and detailed interactions of CB2 selective partial agonist GW-405,833 on active CB2 (magenta) and inactive CB1 (gray, PDB: 5TGZ). It is reported that GW-405,833 acts as CB2 agonist (Ki=3.92 ± 1.58 nM) and CB1 antagonist (Ki=4772 ± 1676 nM).
(B) Comparison of residual energy contribution on GW-405,833 between active CB2 (magenta bars) and inactive CB1 conformations (gray bars).
