Nigericin is an antibiotic derived from Streptomyces hygroscopicus that act as a K + /H + ionophore , promoting K + /H + exchange across mitochondrial membranes. Nigericin is a NLRP3 activator. Nigericin shows promising anti-cancer activities through decreasing intracellular pH (pHi), and inactivation of Wnt / β-catenin signals. Nigericin induces pyroptosis through caspase 1 /GSDMD in TNBC.
