MK-886 inhibits the 5-lipoxygenase activating protein (FLAP), which is involved in the synthesis of leukotrienes. Leukotrienes are inflammatory mediators that can cause bronchoconstriction and increase mucus production in the lungs. By inhibiting FLAP, MK-886 reduces the production of leukotrienes, thereby potentially reducing inflammation and symptoms of asthma.
MK-886 functions by binding to FLAP, thereby preventing the conversion of arachidonic acid to leukotriene A4 (LTA4) by the enzyme [[5-lipoxygenase]]. This inhibition reduces the production of downstream leukotrienes, such as leukotriene B4 (LTB4) and the cysteinyl leukotrienes (LTC4, LTD4, and LTE4), which are potent mediators of inflammation and bronchoconstriction.


In addition to its effects on FLAP, MK-886 also inhibits the peroxisome proliferator-activated receptor alpha (PPARα). PPARα is a nuclear receptor that regulates the expression of genes involved in lipid metabolism and inflammation.

MK-886[edit]

Chemical structure of MK-886

MK-886 is a chemical compound that acts as a leukotriene biosynthesis inhibitor. It is primarily known for its role in inhibiting the enzyme 5-lipoxygenase-activating protein (FLAP), which is crucial in the biosynthesis of leukotrienes. Leukotrienes are inflammatory mediators that play a significant role in conditions such as asthma and allergic rhinitis.

Mechanism of Action[edit]

MK-886 functions by binding to FLAP, thereby preventing the conversion of arachidonic acid to leukotriene A4 (LTA4) by the enzyme 5-lipoxygenase. This inhibition reduces the production of downstream leukotrienes, such as leukotriene B4 (LTB4) and the cysteinyl leukotrienes (LTC4, LTD4, and LTE4), which are potent mediators of inflammation and bronchoconstriction.

Clinical Significance[edit]

The inhibition of leukotriene synthesis by MK-886 has potential therapeutic implications in the treatment of inflammatory diseases. By reducing leukotriene levels, MK-886 may help alleviate symptoms associated with asthma, allergic reactions, and other inflammatory conditions. However, its clinical use is limited, and it is primarily utilized in research settings to study the role of leukotrienes in disease.

Research Applications[edit]

MK-886 is widely used in pharmacological research to investigate the role of leukotrienes in various diseases. It serves as a tool compound to elucidate the pathways involved in leukotriene-mediated inflammation and to explore potential therapeutic targets for drug development.
