Bioactivity Comments
When tested, the racemic mixture of (R) and (S) ARN2508 (compound 10r in [3]) gave IC50 values of 31nM for FAAH, 12nM for COX1 and 430nM for COX2 [3]. Note that the (S) enantiomer is the much more potent COX inhibitor, being ~14000 times more potent for COX1 and 1900 times more potent for COX2 than the (R) enantiomer.
