COX 2 Inhibitor Interactions - Center for Selective C–H
... Acetylation of COX-2 Active Site by Aspirin Aspirin can act as a COX-2 inhibitor, yet it is not as selective as most COX-2 inhibitors. Thus, it will also react with COX-1 enzymes, causing undesired side effects. When aspirin interacts with the COX-2 active site, it permanently acetylates a residue ...
