Used in research to study inflammatory pathways and lipid signaling, methyl arachidonate serves as a stable analog of arachidonic acid. It helps scientists investigate the metabolism of polyunsaturated fatty acids and the production of eicosanoids, which are key mediators in inflammation, immunity, and cell communication. Due to its ability to modulate enzyme activity such as cyclooxygenase and lipoxygenase, it is applied in developing anti-inflammatory drugs and understanding cellular responses in diseases like arthritis, asthma, and cardiovascular disorders. It is also used in lipidomics for tracing metabolic fate and in cell culture studies to manipulate membrane lipid composition.
