Ac-FLTD-CMK 是消皮素 D (GSDMD) 衍生的抑制剂，是炎症性 caspases 的特异性抑制剂。Ac-FLTD-CMK 对 caspases-1 (IC₅₀ 为 46.7 nM)，caspases-4 (IC₅₀ 为 1.49 μM)，caspases-5 (IC₅₀ 为 329 nM) 和 caspases-11 均有效，但对凋亡相关的 caspase-3 无效。

Ac-FLTD-CMK, a gasdermin D (GSDMD)-derived inhibitor, is a specific inflammatory caspases inhibitor. Ac-FLTD-CMK is effective against caspases-1 (IC 50 of 46.7 nM), caspases-4 (IC 50 of 1.49 μM), caspases-5 (IC 50 of 329 nM), and caspases-11 , but not the apoptotic caspases such as caspase-3.

Ac-FLTD-CMK, inhibits GSDMD cleavage by caspases-1, -4, -5, and -11 in vitro, suppresses pyroptosis downstream of both canonical and noncanonical inflammasomes, as well as reduces IL-1β release following activation of the NLRP3 inflammasome in macrophages. By contrast, Ac-FLTD-CMK does not target caspase-3 or apoptotic cell death. Crystal structure of caspase-1 in complex with Ac-FLTD-CMK reveals extensive enzyme-inhibitor interactions involving both hydrogen bonds and hydrophobic contacts. has not independently confirmed the accuracy of these methods. They are for reference only.
