Product Description
Z-WEHD-FMK is a potent, cell-permeable and irreversible caspase-1/5 inhibitor. Z-WEHD-FMK also exhibits a robust inhibitory effect on cathepsin B activity ( IC 50 =6 μM). Z-WEHD-FMK can be used to investigate cells for evidence of apoptosis.
In Vitro
Z-WEHD-FMK (80 μM; 9 hours) elicits a near-complete blockage of C. trachomatis -induced cleavage of golgin-84 and increases GM130 expression in cells. Z-WEHD-FMK (30 min before being exposed to E. piscicida ) effectively inhibits 0909I E. piscicida induced ZF4 cells cytotoxicity and pyroptotic morphology. And in addition, it also inhibits the cytotoxicity induced by cytosolic LPS delivery. Z-WEHD-FMK (20 μM;18-24 hours following Cr 3+ ,Ni 2+ , and Co 2+ ) significantly induces a decrease of 76% to 86% in IL-1β release with 200 to 400 ppm Cr 3+ , it also induces a decrease of 35% to 45% with 48 ppm Ni 2+ or higher, Finally, this caspase-1 inhibitor induced a decrease with 6 ppm Co 2+ , down to a level below the detection threshold, and a decrease of 40% to 48% with 12 to 24 ppm Co 2+ in bone marrow-derived macrophages (BMDM). MCE has not independently confirmed the accuracy of these methods. They are for reference only. Western Blot AnalysisCell Line: C. trachomatis - or mock-infected HeLa cells Concentration: 80 μM Incubation Time: 9 hours Result: Increased golgin-84 and GM130 expression. Cell Viability AssayCell Line: Mycoplasma free-ZF4 cells Concentration: Incubation Time: 30 min before being exposed to E. piscicida Result: Inhibited ZF4 cells cytotoxicity and pyroptotic morphology.
