Ac-YVAD-CMK (Synonyms: N-Ac-Tyr-Val-Ala-Asp-CMK) |
| Catalog No.GC42721 |
Ac-YVAD-CMK is a selective irreversible inhibitor of caspase-1 (Ki=0.8nM), which can prevent the proinflammatory cytokine IL-1β activation. Ac-YVAD-CMK can reduce the inflammatory response and induce a long-lasting neuroprotective effect.

Ac-YVAD-CMK is a selective irreversible inhibitor of caspase-1 (Ki=0.8nM), which can prevent the proinflammatory cytokine IL-1β activation. Ac-YVAD-CMK can reduce the inflammatory response and induce a long-lasting neuroprotective effect[1,2,3].
Ac-YVAD-CMK reduced the expression of IL-1β and IL-18 in activated microglia in vitro[3]. Ac-YVAD-CMK(40μM) decreased the rapid cell (PAMs, 3D4/21 cells and the endothelial cell line) death induced by ApxⅠ[4]. Ac-YVAD-CMK attenuated the inhibitory effects of berberine on the viability, migration and invasion of HepG2 cells[5].
AC-YVAD-CMK treatment significantly alleviated sepsis-induced acute kidney injury, with decreased histological injury in renal tissues, suppressed the accumulation of neutrophils and macrophages in renal tissues, and decreased sCR and BUN level[6]. Ac-YVAD-CMK protected the brain against ICH-induced injury, and the neuroprotective effect may result from anti-inflammation-induced blood–brain barrier protection[7]. Pretreatment of rats with Ac-YVAD-CMK (12.5mM/kg) significantly reduced endotoxin-induced mortality from 83% to 33% using Log Rank analysis[8].
