divalent

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.

Ionomycin calcium (SQ23377 calcium) is an effective and selective calcium ionophore, demonstrating high specificity for divalent cations (Ca>Mg>Sr=Ba).

Phytic acid sodium salt (Sodium phytate hydrate) is known to function as a [PO4]3- storage depot and a precursor for other inositol phosphates and pyrophosphates. It is a potent chelator of divalent and trivalent cations in vitro.

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.
