BAY-678 is an orally bioavailable, highly potent, selective, and cell-permeable inhibitor of human neutrophil elastase (HNE), with an IC₅₀ of 20 nM. It has been nominated as a chemical probe to the public via the Structural Genomics Consortium (SGC). It demonstrates significant efficacy in preclinical models of ALI and lung emphysema, showing anti-inflammatory and anti-remodeling actions. Additionally, it has shown beneficial pulmonary hemodynamic and vascular effects in models of PAH in rats and mice.
