Arachidonic acid cascade enzyme

The term "Arachidonic acid cascade enzymes" refers collectively to the family of enzymes responsible for metabolizing arachidonic acid into bioactive lipid mediators known as eicosanoids. These include key enzyme classes such as phospholipases (notably phospholipase A₂), cyclooxygenases (COX‑1, COX‑2), lipoxygenases (5-lipoxygenase, among others), various synthases downstream from these pathways, and cytochrome P450 monooxygenases. The products generated by these enzymatic reactions—prostaglandins, thromboxanes, leukotrienes—play central roles in regulating inflammation, pain perception, immune responses, vascular tone, platelet function, fever generation, and other physiological processes. Because dysregulation or overactivation of this pathway contributes to numerous diseases—including inflammatory conditions like arthritis or asthma; pain syndromes; cardiovascular disease; certain cancers—the individual component enzymes are major therapeutic targets. Drugs that inhibit one or more steps in this cascade are widely used clinically but can have significant safety concerns depending on their selectivity profile. Note: For structured data purposes it is recommended to refer to specific canonical targets within this group rather than the collective term "Arachidonic acid cascade enzyme."
