a-23187 hemicalcium

Calcimycin (A-23187) hemicalcium salt 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 (A-23187) hemimagnesium, an antibiotic and divalent cation ionophore (such as calcium and magnesium), serves various biological roles. It triggers Ca2+-dependent cell death by elevating intracellular calcium levels and suppresses the growth of Gram-positive bacteria and certain fungi. Additionally, this compound hinders ATPase activity and uncouples oxidative phosphorylation (OXPHOS) in mammalian cells, ultimately leading to apoptosis [1] [2] [3] [4].

Calcimycin (A-23187) is an ionophorous, polyether carboxylic antibiotic from Streptomyces chartreusensis. It binds and transports calcium and other divalent cations across membranes, uncouples oxidative phosphorylation, and inhibits ATPase of rat liver mitochondria. The substance is primarily used as a biochemical tool to study the role of divalent cations in various biological systems.
