生物活性:
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.

体内研究:
Calcimycin (A-23187) hemimagnesium (2.5 or 7.5 nM; intrapleurally) induces protein leakage.Animal Model:Mice (ICR, 25-30 g)
Dosage:2.5 or 7.5 nM
Administration:Intrapleurally
Result:Two hours after 2.5 nM, or three hours after 7.5 nM, challenge the protein levels in the pleural cavity were equivalent to about a half of their corresponding peak values.

体外研究:
Calcimycin (A-23187) hemimagnesium mediates mycobacterial killing by inducing intracellular calcium-regulated autophagy in a P2RX7 dependent manner.
