| Bioactivity | Nigericin sodium salt is an antibiotic from Streptomyces hygroscopicus that works by acting as an H+, K+, and Pb2+ ionophore, a NLRP3 activator[1]. |
| Invitro | Nigericin (0.1 µM) decreases inhibits proliferation and clonogenicity of H460 lung cancer cells in a dose dependent manner. Nigericin inhibits migration and invasion of H460 lung cancer cells[1]. Nigericin (0.1-10 nM) has apparently a dual effect on cell volume, that is a shrinking effect at lower Nigericin concentrations and a swelling effect at higher concentrations. Nigericin (0.1-1 nM) significantly decreases cytosolic pH (pHi), and slightly increases the pHi at 5 and 10 nM[2]. Nigericin exhibits higher toxicity on S18 cells than S26 cells, with IC50 of 2.03±0.55 μM and 4.77±2.35 μM, respectively. Nigericin can selectively kill cancer stem cells in NPC in vitro. Nigericin dramatically reduces the migration ability of S18 and HONE-1 cells[3]. Nigericin exhibits gteat toxicity for the HT29 and SW116 cell line with IC50 of 12.92±0.25 μmol and 15.86±0.18 μmol. Nigericin also shows a decreased ability to form colonies under anchorage-independent conditions in a standard soft agar assay[4]. |
