Benoxaprofen BiologicalActivity
| Description | Benoxaprofen (LRCL 3794) is a potent and long-acting anti-inflammatory and antipyretic compound. Benoxaprofen is a relatively weak inhibitor of cyclooxygenase in in vitro systems, inhibits lipoxygenase in other systems, and inhibits monocyte migration in some animal models of inflammation[1][2]. |
