| Description | Ac-YVAD-CMK (Ac-Tyr-Val-Ala-Asp-CMK) is a selective and irreversible inhibitor of Caspase-1 and inhibits pyroptosis, IL-1β and IL-18. Ac-YVAD-CMK shows neuroprotective and anti-inflammatory capacity. |
| In vitro | Ac-YVAD-cmk (40 and 80 μM) reduces the expression of IL-1β and IL-18 in activated microglia[3]. |
| In vivo | In SD rats, Ac-YVAD-cmk treatment (1 μg; injection into the left lateral ventricle) significantly decreases the protein levels of caspase-1 and mature IL-1β/IL-18 compared with the ICH group[3]. Ac-YVAD-cmk (12.5 μmol/kg) significantly reduces mortality from 83 to 33% in rats[4]. |
