BAY-678_product_DataBase

Bioactivity

BAY-678 is an orally bioavailable, highly potent, selective and cell-permeable inhibitor of human neutrophil elastase (HNE), with an IC50 of 20 nM. BAY-678 is also nominated as a chemical probe to the public via the Structural Genomics Consortium (SGC).

Target

IC50: 20 nM (HNE).

Invitro

BAY-678 is an orally bioavailable, highly potent, selective and cell-permeable inhibitor of human neutrophil elastase (HNE), with an IC50 of 20 nM. The Ki value of BAY-678 for MNE is 700 nM. BAY-678 is the 4th generation inhibitor of HNE[1]. BAY-678 is also nominated as a chemical probe to the public via the Structural Genomics Consortium (SGC)[2]. BAY-678 has more than 2,000-fold selectivity in a panel of 21 serine proteases[3].

In Vivo

BAY-678 (17) reveals significant efficacy in preclinical models of ALI and lung emphysema, demonstrating their anti-inflammatory and anti-remodeling mode of action. Additionally, BAY-678 (17) has shown significant beneficial pulmonary hemodynamic and vascular effects in models of PAH in rats and mice[2].
