Biochem/physiol Actions
Ac-FLTD-CMK is a selective gasdermin D (GSDMD) clevage inhibitor (IC50 = 46.7 nM, 329 nM, 1.49 μM, respectively, against GSDMD clevage by human caspase-1, -5, -4 in cell-free enzymatic assays) that suppresses pyroptosis downstream of both canonical and noncanonical inflammasomes, as well as reduces IL-1β release following activation of the NLRP3 inflammasome in macrophages (10 μM 4h post 200 ng/mL LPS and 0.5h before ATP or nigericin). Ac-FLTD-CMK selectively blocks GSDMD clevage by inflammatory caspases without affecting apoptotic caspases (caspase-3 IC50 >100 μM) or apoptosis.

During invasion, Entamoeba histolytica (Eh) encounter macrophages and activate them to elicit tissue damaging pro-inflammatory responses. When Eh binds macrophages via the Gal-lectin, surface EhCP-A5 RGD sequence ligates α5β1 integrin to activate caspase-1 in a complex known as the NLRP3

Pyroptosis has been reported to contribute to the traumatic brain injury (TBI) process. Ac-FLTD-CMK is a newly synthesized pyroptosis inhibitor. However, whether Ac-FLTD-CMK inhibits pyroptosis and plays a neuroprotective role after TBI is unknown. The present study aimed to determine

The inflammasomes are signaling platforms that promote the activation of inflammatory caspases such as caspases-1, -4, -5, and -11. Recent studies identified gasdermin D (GSDMD) as an effector for pyroptosis downstream of the inflammasome signaling pathways. Cleavage of GSDMD by
