    Background
    
    IC50: 0.75 μM, 0.65 μg/ml, and 1.2 μg/ml for 5-LO, COX-1, and COX-2, respectively
    BW 755C is a dual inhibitor of 5-lipoxygenase (5-LO) and cyclooxygenase (COX) pathways.
    Constitutive cyclooxygenase (COX-1) is present in cells under physiological conditions, whereas COX-2 is induced by some cytokines, mitogens, and endotoxin in pathological conditions, such as inflammation. Since 5-lipoxygenase (5-LO) oxidizes arachidonic acid to 5-hydroperoxyeicosatetraenoic acid in the first step of the leukotriene pathway, 5-LO inhibitors should prevent leukotriene biosynthesis and thus prove useful in the treatment of allergic asthma.
    In vitro: Previous study found that BW 755C and other nonsteroidal antiinflammatory drugs including diclofenac, acetaminophen, and naproxen showed approximately equipotent inhibitory effects on COX-1 and COX-2 in intact cells. Whereas, BF 389 was the most potent and most selective inhibitor of COX-2 in intact cells [1].
    In vivo: An animal study was conducted to examine whether BW-755C delayed neuronal death in the hippocampal CA1 sector in Mongolian gerbils after 5 minutes of forebrain ischemia. Gerbils were injected with BW-755C. Seven days after ischemic insult, the animals were perfusion-fixed, and the neuronal density in the hippocampal CA, sector was estimated. Results showed that in ischemic gerbils with vehicle administration, the average neuronal density was 13 for BW-755C. In ischemic gerbils treated with 30 mg/kg BW-755C, the average neuronal densities was 14 [2].
    Clinical trial: So far, no clinical study has been conducted.
