Ac-YVAD-cmk (Caspase-1 Inhibitor II) is a selective caspase-1 (IL-1beta converting enzyme, ICE)) inhibitor with neuroprotective and anti-inflammatory effects. Ac-YVAD-cmk effectively suppresses the expression of IL-1β and IL-18. Ac-YVAD-cmk inhibits pyroptosis in many diseases[1][2].

In Vitro	Ac-YVAD-cmk (40 μM or 80 μM) reduces the expression of IL-1β and IL-18 in activated microglia in vitro[2].
In Vivo	Ac-YVAD-cmk treatment (1 μg/rats; SD rat; injected into the left lateral ventricle) significantly decreases the protein levels of caspase-1 (p20), mature IL-1β/IL-18 compared with the ICH group[2]. Ac-YVAD-cmk (rats with ac-YVAD-cmk at a dose of 12.5 μmol/kg) significantly reduces mortality from 83 to 33% using Log Rank analysis[3].
