LSALT peptide
LSALT peptide is a selective DPEP-1 inhibitor with selectivity over DPEP2/3. LSALT peptide inhibits neutrophil and monocyte/macrophage recruitment, inflammation, and tissue injury. LSALT peptide reduces kidney damage, improves survival in murine sepsis and endotoxemia models. LSALT peptide can be used for the research of COVID-19, sepsis, acute respiratory distress syndrome, and acute kidney injury.

Description
In Vitro
LSALT peptide binds specifically to human DPEP1, with no detectable binding to the closely related DPEP2 or DPEP3 proteins expressed on COS1 cells[2].
LSALT peptide (4 h) inhibits human neutrophil binding to pro-inflammatory stimulus-activated primary human lung endothelial cells[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
In Vivo
LSALT peptide (i.v.; single dose (5 minutes post-LPS) or two doses (5 minutes and 18 hours post-LPS)) significantly improves survival in a lethal murine endotoxemia model, and reduces LPS-induced acute lung injury[2].
LSALT peptide significantly reduces mortality and organ damage in a murine polymicrobial sepsis model[2].
