5-LO Inhibitors

Santa Cruz Biotechnology now offers a broad range of 5-LO Inhibitors. 5-lipoxygenase (5-LO) is expressed primarily in polymorphonuclear leukocytes, macrophages, and mast cells. 5-LO performs the first two catalytic reactions in the biosynthesis of leukotrienes. 5-LO Inhibitors offered by Santa Cruz inhibit 5-LO and, in some cases, other leukotriene and lipid metabolite biosynthesis related proteins. View detailed 5-LO Inhibitor specifications, including 5-LO Inhibitor CAS number, molecular weight, molecular formula and chemical structure, by clicking on the product name.
