Extended Data Fig. 3 ∣. CQ31 releases CQ04 in cells and causes pyroptosis.
(a) The indicated MV4;11 cells were treated with CQ04 or CQ31 for 24 h before assessing cell viability by CTG. Data are means ± SEM of 3 biological replicates. (b) The indicated MV4;11 cells were treated with CQ31 (16 μM) or VbP (16 μM), incubated for 4 h, and stained with PI. PI uptake was recorded for 12 h. Data are means ± SEM of 10 replicates. a and b are representative of three or more independent experiments. (c) HEK 293T cells were treated with vehicle control (DMSO) or CQ31(10 μM) for 24 h before intracellular metabolites were extracted. Methyl ester and free acid of CQ31 were measured by LC-MS and confirmed against pure standards.
