Cyclooxygenase inflammation
WebDec 1, 2015 · Cyclooxygenase (COX) is the rate-limiting enzyme that is responsible for the first 2 steps in the synthesis of PGs. The COX enzyme exists in 2 isoforms, COX-1 and COX-2. These 2 isoforms have a comparable molecular mass of 71 and 73 kDa, respectively, but their expression and distribution within the renal tissue are different. WebCyclooxygenase COX is involved in the synthesis of prostanoids, such as prostaglandins, prostacyclin, and thromboxane. 58 COX converts arachidonic acid to prostaglandin H 2; this is the first step in prostanoid production and is the rate-limiting step in prostaglandin production. Three COX isoenzymes are currently known (COX-1, COX-2, and COX-3).

WebNSAIDs function by reducing the activity of the prostaglandin-producing enzymes cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2). The GI tract, platelets, and kidneys all function normally thanks in part to the prostaglandins that are produced by COX-1. Inflammation and pain are caused by prostaglandins, which are produced by COX-2.
