BAY-678

Uses

BAY 678, is a human neutrophil elastase (HNE) inhibitor with >2,000-fold selectivity for HNE over a panel of 21 other serine proteases.

Biological Activity

bay-678 is an orally active, potent and selective inhibitor of human neutrophil elastase (hne) [1][2].human neutrophil elastase (hne) is a member of the chymotrypsin-like family of serine proteases and is stored in the neutrophil cytoplasm. hne is a key protease for matrix degradation and high hne activity is occured in inflammatory diseases. so hne is a potential target for the treatment of pulmonary diseases such as acute lung injury (ali), acute respiratory distress syndrome (ards), chronic obstructive pulmonary disease (copd), bronchiectasis (be), and pulmonary hypertension (ph) [1].bay-678 is an orally active, potent and selective inhibitor of human neutrophil elastase (hne). bay-678 inhibited hne reversibly with ic50 value of 20 nm and ki value of 15 nm. bay-678 showed no inhibition against 21 related serine proteases, up to a concentration of 30 μm [1].in rats, bay-678 showed medium clearance with t1/2 of 1.3h [1].
