General description

1,2-Bis(2-aminophenoxy)ethane-N,N,N′,N′-tetraacetic acid is a highly selective calcium chelating reagent. Effect of microinjected calcium-loaded 1,2-bis(2-aminophenoxy)ethane-N,N,N′,N′-tetraacetic acid (CaBAPTA) on cell-to-cell diffusion of carboxyfluorescein has been studied in staminal hairs of Setcreasea purpurea. It is reported to be a metabolite of 1,2-bis(2-aminophenoxy)ethane-N,N,N′,N′-tetraacetic acid tetra(acetoxymethyl ester) (BAPTA-AM) in rat urine.
pH 8.0 Highly selective calcium chelating reagent. Suitable for the spectrophotometric monitoring of Ca2+ levels

Application

1,2-Bis(2-aminophenoxy)ethane-N,N,N′,N′′-tetraacetic acid was used for the spectrophotometric monitoring of Ca2+ levels. It may be used as chelator of cytosolic Ca²+ to investigate the effect of methoxychlor on cytosolic free Ca²+ concentrations and apoptosis in HA59T human hepatoma cells.
Highly selective calcium chelating reagent. Suitable for the spectrophotometric monitoring of Ca2+ levels

The effect of microinjected calcium-loaded 1,2-bis(2-aminophenoxy) ethane-N,N,N',N'-tetraacetic acid (CaBAPTA) on cell-to-cell diffusion of carboxyfluorescein (CF) was examined in staminal hairs of S. purpurea Boom. The CaBAPTA was microinjected into the cytoplasm of the staminal hairs either with CF or prior

A role for increases in intracellular calcium (Ca2+) has been suggested in the pathophysiology of various forms of oxidant-mediated cell injury. In recent studies, we found that iron bound to the Pseudomonas aeruginosa siderophore, pyochelin, augments oxidant-mediated endothelial cell injury

This paper describes a new series of organometallic water-soluble chelators combining a redox moiety (ferrocene) and a selective Ca2+ chelator (BAPTA) separated by an ethynyl bridge. We report the synthesis and characterization of organometallic derivatives of the BAPTA chelator featuring
