General description

A cell-permeable potent and selective inhibitor of COX-2 from human monocytes (IC50 = 650 nM) and in whole blood (IC50 = 4.3 µM). Displays only very weak activity against COX-1 from human platelets (IC50 >10 µM) and in whole blood (IC50 >100 µM).
A cell-permeable potent, selective inhibitor of cyclooxygenase-2 (COX-2) (IC50 = 650 nM, human monocytes COX-2). Shown to specifically inhibit COX-2 in human whole blood (IC50 = 4.3 µM). Displays only weak inhibitory activity against COX-1 from human platelets (19% inhibition at 10 µM) and in whole blood (25% inhibition at 100 µM).

Cyclooxygenase-2 (COX-2) is a biomolecule known to be overexpressed in inflammation. Therefore, it has been considered a diagnostically useful marker in numerous studies. In this study, we attempted to assess the correlation between COX-2 expression and the severity of intervertebral
