Product Data
Biological target:
Sivelestat is a competitive inhibitor of human neutrophil elastase, with an IC50 of 44 nM and a Ki of 200 nM.
In vitro activity:
The combination of sivelestat and trastuzumab might be a novel therapeutic strategy for HER2-positive breast cancer. Sivelestat effectively suppressed the tumor progression mechanism initiated by neutrophil elastase (NE) through tumor growth factor-α (TGF-α) in breast cancer cells, while the impact of trastuzumab was hindered by TGF-α. However, the combination of trastuzumab and sivelestat resulted in more potent suppression of cell proliferation, overcoming the impairment by TGF-α on HER2 down-regulation.

In vivo activity:
Sivelestat attenuated AngII-induced abdominal aortic aneurysm through the inhibition of neutrophil elastase. In the 1-week study in male apolipoprotein E-deficient mice, AngII increased plasma and tissue elastase activity and aortic width, which were reduced by sivelestat. Sivelestat also decreased the incidence of abdominal aortic aneurysms and mitigated elastin fragmentation induced by AngII. Inflammatory cell accumulation and MMP-2/9 enhancement by AngII were reduced by sivelestat. Reference: Am J Hypertens. 2023 Nov 20:hpad107. https://pubmed.ncbi.nlm.nih.gov/37982444/
