BAY-678 racemate

Description: BAY-678 racemate is a racemate of BAY-678 which is a novel, potent, orally bioavailable, selective and cell-permeable inhibitor of human neutrophil elastase (HNE) with an IC50 of 20 nM. Human neutrophil elastase (HNE) is a key protease for matrix degradation. High HNE activity is observed in inflammatory diseases. Accordingly, HNE is a potential target for the treatment of pulmonary diseases such as chronic obstructive pulmonary disease (COPD), acute lung injury (ALI), acute respiratory distress syndrome (ARDS), bronchiectasis (BE), and pulmonary hypertension (PH). HNE inhibitors should reestablish the protease-anti-protease balance. BAY-678 is also nominated as a chemical probe to the public via the Structural Genomics Consortium (SGC). BAY-678 has a favorable pharmacokinetic profile. The cell based activity of BAY-678 on HNE is not relevant and has not been measured. Efficacy was demonstrated in acute in vivo models, for example, protease-induced acute lung injury (ALI) in mice, where exogenous HNE in the mouse lung was inhibited with Ki = 15 nM after oral administration.
