We provide customized and high-quality BW-B 70C product for your project.

BW B70C is a potent and selective inhibitor of 5-lipoxygenase (5-LO). 5-LO is an enzyme that transforms essential fatty acids (EFAs) into leukotrienes and is activated by 5-lipoxygenase activating protein (FLAP). BW-B 70C had high potency and long duration in vivo and was considered as potential anti-asthma drug. It was reported that BW B70C blocks leukotriene C4 synthesis by alveolar macrophages, which decreases the migration for leukocyte to the airway lumen. BW B70C didn't affect vascular leucocyte margination and the blood levels of secreted phospholipase A2 and TNF-α.
