Calcimycin (A-23187) hemicalcium hemimagnesium is an antibiotic and a unique divalent cation ionophore (like calcium and magnesium). Calcimycin hemicalcium hemimagnesium induces Ca2+-dependent cell death by increasing intracellular calcium concentration. Calcimycin hemicalcium hemimagnesium inhibits the growth of Gram-positive bacteria and some fungi. Calcimycin hemicalcium hemimagnesium also inhibits the activity of ATPase and uncouples oxidative phosphorylation (OXPHOS) of mammalian cells. Calcimycin hemicalcium hemimagnesium induces apoptosis and autophagy.

    Customer Validation
     Cells were treated with different concentrations of Calcimycin (A23187: 2 µmol/L, 4 µmol/L, 8 µmol/L, 10 µmol/L; 24 h), and the effect of A23187 on STAT1 expression was assessed by Western blotting.

    Customer Validation
     Cells were treated with A23187 (4 µmol/L; 24 h) to examine the effect of A21187 on the binding ability of TRIM21 and STAT1 by Co‐IP and western blotting, and the result showed that A23187 reversed the dissociation of TRIM21 and STAT1 in the context of TGM2 and increased ubiquitination of STAT1.

    Customer Validation
     The effect of A23187 (4 µmol/L; 0-96 h) and ZM39923 (20 nmol/L) on GC cell proliferation was evaluated by CCK8 assay. The result showed that ZM39923 promoted cell proliferation while A23187 had an inhibitory role in GC cell proliferation.
