Ac-FLTD-CMK is a specific inhibitor for inflammatory caspases . Ac-FLTD-CMK inhibits gasdermin D (GSDMD) cleavage by caspases-1, -4, -5, and -11 in vitro. Ac-FLTD-CMK is effective against caspases-1, caspases-4 and caspases-5 with IC50 of 46.7 nM, 1.49 μM and 329 nM, respectively.
A GSDMD-derived inhibitor, N-acetyl-Phe-Leu-Thr-Asp-chloromethylketone (Ac-FLTD-CMK), inhibits GSDMD cleavage in vitro and suppresses pyroptosis downstream of both canonical and noncanonical inflammasomes.
In vivo
Ac-FLTD-CMK inhibits pyroptosis and exerts neuroprotective effect in a mice model of traumatic brain injury.
