Irreversibly inactivates both cox-1 and cox-2
WebCOX-1 and COX-2 are both targets of common nonspecific nonsteroidal anti-inflammatory drugs (nsNSAIDs), including ibuprofen and naproxen (Fig. 1). Aspirin is a nsNSAID that unlike other inhibitors covalently and irreversibly modifies COXs by acetylating Ser-530 and interfering with AA access to the COX active site (9–14). COX-2 “specific ...

WebMethods: To measure COX-2 activity, cells were transiently pre-treated with aspirin to irreversibly inhibit constitutive COX-1, treated with lipopolysaccharide (LPS) to induce COX-2 and then stimulated with AA. Results: In LPS treated monocytes pre-treated transiently with aspirin, neither the level of induced COX-2 nor the activity was affected.
