Disease relevance of Glycine, N,N'-(1,2-ethanediylbis(oxy(5-fluoro-2,1-phenylene)))bis(N-(carboxymethyl)-

  • We used ion-selective electrodes, nuclear magnetic resonance spectroscopy, and the four-electrode method to perform four series of experiments in the isolated blood-perfused rabbit heart loaded with 5F-BAPTA during 30 to 35 minutes of no-flow ischemia [1].
  • We explored the role of intracellular free calcium in the pathophysiology and pathogenesis of ventricular fibrillation in perfused ferret hearts loaded with the Ca2+ indicator 5F-BAPTA [2].
  • To elucidate the mechanism of contractile dysfunction in postischemic ("stunned") myocardium, time-resolved measurements of intracellular free Ca2+ concentration ([Ca2+]i) were made using gated 19F nuclear magnetic resonance in seven perfused ferret hearts loaded with the fluorinated Ca2+ indicator 5F-BAPTA [3].
  • The effects of the heavy-metal ions Cd2+ and Zn2+ on the homoeostasis of intracellular free Ca2+ in E367 neuroblastoma cells were examined using 19F-NMR spectroscopy with the fluorinated chelator probe 1,2-bis-(2-amino-5-fluorophenoxy)ethane-N,N,N', N'-tetra-acetic acid (5F-BAPTA) [4].
  • In other NMR studies, where 5F-BAPTA was not used, metabolic toxicity was modulated by three glutamate receptor antagonists: dizocilpine, NBQX and kynurenic acid [5].
 

High impact information on Glycine, N,N'-(1,2-ethanediylbis(oxy(5-fluoro-2,1-phenylene)))bis(N-(carboxymethyl)-

  • 19F NMR in combination with 1,2-bis(2-amino-5-fluorophenoxy)ethane-N,N,N',N'-tetraacetic acid (5F-BAPTA) was used to simultaneously measure [Ca2+]i and intracellular free Pb2+ concentration ([Pb2+]i) in the rat osteoblastic bone cell line ROS 17/2 [6].
  • Developed pressure recovers to only 50% of control values during reflow, indicating that the presence of 5F-BAPTA in the cytosol does not protect against stunning, at least when the extracellular calcium concentration has been raised to 8 mM [7].
  • Although the nonlinear response of 5F-BAPTA to [Ca2+] leads to underestimation of the true time-averaged [Ca2+]i, the measured alterations of intracellular Ca2+ homeostasis during ischemia are large compared with the likely errors in quantification [7].
  • Several lines of evidence are presented to show that loading with the acetoxymethyl ester of 5F-BAPTA is not significantly complicated by accumulation of partially de-esterified metabolites, compartmentalization into mitochondria, or disproportionate uptake into endothelial cells [7].
  • In this study, 1,2-bis(2-amino-5-fluorophenoxy)ethane N,N,N',N'-tetraacetic acid (5F-BAPTA) was used to buffer Pb2+ and Ca2+ concentrations in the PKC reaction mixture [8].
 

Anatomical context of Glycine, N,N'-(1,2-ethanediylbis(oxy(5-fluoro-2,1-phenylene)))bis(N-(carboxymethyl)-

  • Using 19F-NMR spectroscopy of rat cortical synaptosomes loaded with the fluorinated chelator 1,2-bis(2-amino-5-fluorophenoxy)ethane-N,N,N',N'- tetraacetic acid (5F-BAPTA), we have determined unambiguously that MeHg increases the free intrasynaptosomal Zn2+ concentration ([Zn2+]i) [9].
  • The intracellular free calcium ion concentration ([Ca2+]i) of the neuroblastoma x glioma hybrid cell line, NG108-15, was measured using the 19F-nuclear magnetic resonance divalent cation indicator, 1,2-bis(2-amino-5-fluorophenoxy)ethane-N,N,N',N'-tetra-acetic acid (5F-BAPTA) [10].
 

Associations of Glycine, N,N'-(1,2-ethanediylbis(oxy(5-fluoro-2,1-phenylene)))bis(N-(carboxymethyl)- with other chemical compounds

 

Analytical, diagnostic and therapeutic context of Glycine, N,N'-(1,2-ethanediylbis(oxy(5-fluoro-2,1-phenylene)))bis(N-(carboxymethyl)-

  • We conclude that 5F-BAPTA provides useful measurements that reveal that time-averaged [Ca2+]i rises during ischemia and returns to control levels soon after reperfusion [7].
