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.

Ac-FEID-CMK TFA is a selective zebrafish GSDMEb-derived peptide inhibitor that reduces mortality and renal injury in infectious shock. It inhibits pyroptosis in vivo, attenuates septic AKI (acute kidney injury), and inhibits the caspy2-mediated atypical inflammatory vesicle pathway.

Apilimod 2HCl (STA 5326 2HCl) is a PIKFYVE kinase inhibitor that promotes NLRP3 inflammatory vesicle activation, IL-1β secretion, and cellular pyroptosis, and is used in the study of amyotrophic lateral sclerosis.

Caspase-3 activator 1 (compound 4b), a Ru(III) metal complex, effectively inhibits gastric tumor growth and metastasis by mediating caspase-3 cleavage, enabling Caspase-3 to process gasdermin E (GSDME), resulting in GSDME-N terminus production and perforation of the gastric tumor cell membrane. Furthermore, compound 4b induces pyroptosis and subsequent immune responses and can be incorporated with decitabine (DCT) into the 4b-DCT-Lip lipid delivery system [1].

CIB-1476, a caspase-1 inhibitor, effectively reduces joint swelling in mouse models of arthritis and demonstrates lasting anti-inflammatory effects. This compound achieves its benefits by blocking IL-1β production, NF-κB activation, and GSDMD-mediated pyroptosis, all of which are triggered by the NLRP3 inflammasome.
