k+/h+ ionophore

Nigericin is a polyether antibiotic with potent antimicrobial, antimalarial, anticoronaviral and anticancer activities. It is capable of promoting cellular potassium efflux, inducing Caspase-1 GSDMD and Caspase-3-mediated cellular pyroptosis and apoptosis in triple-negative breast cancer, and inducing apoptosis in PEL (primary exudative lymphoma) cells through mitochondrial dysfunction and Wnt β-catenin signaling downregulation.

Nigericin sodium salt is an antibiotic, an NLRP3 activator, and a cationic ion carrier. Nigericin sodium triggers the activation of the NALP3 inflammasome, which inhibits Golgi function and suppresses the growth of Gram-positive bacteria.
