We report further expansion of the structure activity relationship (SAR) on the triaryl bis sulfone class of compounds (I), which are potent CB2 receptor ligands with excellent selectivity over the CB1 receptor. This study was extended to B ring changes, followed by simultaneous optimization of the A-, B-, and C-rings. Compound 42 has excellent CB2 potency, selectivity and rat exposure.
