CQ80
CQ80 is a PEPD/XPNPEP1 inhibitor and selective CARD8 inflammasome activator. CQ80 has IC50 values of 0.91 μM for PEPD, 43 μM for XPNPEP1. CQ80 promotes the accumulation of Xaa-Pro peptides by inhibiting PEPD and XPNPEP1, releases the fragment of CARD8 for inflammasome formation, and induces pyroptosis via GSDMD cleavage. CQ80 can be used for research on inflammasome, CARD8-expressing cancer cells, HIV-1-infected cell clearance, acute myeloid leukemia (AML).

CQ80 (0.15 nM-100 μM; 24 h) induces CASP1-dependent pyroptosis in MV4-11 cells with an IC50 of 0.27 μM, and shows potent cytotoxicity against OCI-AML2 cells[1].
CQ80 (6.25 μM; 6 h) promotes Propidium Iodide (PI) (HY-D0815) uptake in MV4-11 and OCI-AML2 cells, indicating lytic cell death[1].
CQ80 (20 μM; 24 h) induces lactate dehydrogenase (LDH) release and gasdermin D (GSDMD) cleavage in MV4-11, OCI-AML2, THP-1 cells and human resting T cells[1].
CQ80 (20 μM; 24 h) shows no activity in N/TERT-1 keratinocytes, mouse bone marrow-derived macrophages (BMDMs) and RAW264.7 cells, failing to activate NLRP1 inflammasome[1].
CQ80 (20 μM; 24 h) does not induce additional pyroptosis in DPP8/9 knockout THP-1 cells, and PEPD/XPNPEP1 double knockout THP-1 cells are completely resistant to CQ80[1].
CQ80 (20 μM; 6 h) disrupts the CARD8-DPP9 ternary complex in HEK293T cells stably expressing CASP1 and GSDMD[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
