Non-aromatic A-ring replacement in the triaryl bis-sulfone CB2 receptor inhibitors
摘要:
The triaryl bis-sulfone 1 was modified by converting the aryl A-ring to a piperidine ring. The piperidine ring was further elaborated to a spirocyclopropyl piperidine moiety. The effect on CB2 binding potency, rat calcium channel affinity, and CYP 2C9 inhibition is described. (C) 2009 Elsevier Ltd. All rights reserved.

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.
