Nigericin sodium salt is an antibiotic derived from Streptomyces hygroscopicus that act as a K+/H+ ionophore, promoting K+/H+ exchange across mitochondrial membranes. Nigericin sodium salt is a NLRP3 activator. Nigericin sodium salt shows promising anti-cancer activities through decreasing intracellular pH (pHi), and inactivation of Wnt/beta-catenin signals. Nigericin sodium salt induces pyroptosis through caspase 1/GSDMD in TNBC[1][2][3][4][5][6][7].
