Calcimycin (A23187) is an antibiotic and a unique divalent cation ionophore (like calcium and magnesium). It induces Ca2+-dependent cell death by increasing intracellular calcium concentration. Calcimycin inhibits the growth of Gram-positive bacteria and some fungi. Calcimycin also inhibits the activity of ATPase and uncouples oxidative phosphorylation of mammalian cells. It induces apoptosis[1][2][3][4].
