Enofelast (BI-L-239) is a potent and selective 5-lipoxygenase inhibitor. It inhibited leukotriene B4 and C4 generation. In animal models, enofelast attenuates bronchoconstriction, leukocyte infiltration, inflammation and hyperresponsiveness that characterize asthma.

Sample Use Guides

In Vitro Use Guide

In vitro enofelast (BI-L-239) inhibited 5-lipoxygenase product generation from human lung mast cells, alveolar macrophages, and peripheral blood leukocytes with a concentration that would provide 50% inhibition values of 28 to 340 nmol/L.
