Uses
Calcimycin (A-23187) hemimagnesium is an antibiotic and a unique divalent cation ionophore (like calcium and magnesium). Calcimycin hemimagnesium induces Ca2+-dependent cell death by increasing intracellular calcium concentration. Calcimycin hemimagnesium inhibits the growth of Gram-positive bacteria and some fungi. Calcimycin hemimagnesium also inhibits the activity of ATPase and uncouples oxidative phosphorylation (OXPHOS) of mammalian cells. Calcimycin hemimagnesium induces apoptosis[1][2][3][4].
