Leukotrienes (LTs) are a group of inflammatory lipid mediators derived from arachidonic acid (AA) via the 5-lipoxygenase (5-LOX) pathway. A characteristic feature of LTs is that they are produced by leukocytes and share a conjugated triene structure. LTs consist of cysteinylleukotrienes (CysLTs) and leukotriene B4 (LTB4). CysLTs contain a cysteine ring, whereas LTB4 is a noncysteine containing dihydroxy-leukotriene. The subtypes of CysLTs include leukotriene C4 (LTC4), leukotriene D4 (LTD4), and leuko......
