Calcimycin (A-23187) is an antibiotic and a unique divalent cation ionophore (like calcium and magnesium). Calcimycin 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 (OXPHOS) of mammalian cells. Calcimycin induces apoptosis.

How to use

In Vitro:

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

In Vivo:

Calcimycin (A-23187) (2.5 or 7.5 nM; intrapleurally) induces protein leakage.
