متن کاملREDUCTION OF Np ( V 1 ) AND Pu ( V 1 ) BY ORGANIC CHELATING AGENTS
Abstract The reduction of N p O P and P u O p by oxalate, citrate, and ethylenediaminetetraacetic acid OST1 (EDTA) was investigated in low ionic strength media and brines. This was done to help establish the stability of the An(VI) oxidation state in the presence of organic complexants. The stability of the An(VI> oxidation state depended on the pH and relative strength of the various oxidation...
متن کاملActivation of human creatine kinase isoenzymes by pH and various sulfhydryl and chelating agents.
We report the effect of serum pH and of the presence or absence of mercaptoethanol, N-acetyl-L-cysteine, monothioglycerol, ethylenediaminetetraacetate, and ethylene glycol-bis(beta-aminoethyl ether)-N,N,N',N'-tetraacetate on the activation of the human creatine kinase isoenzymes. At the serum pH giving maximal enzyme stability and minimal assay lag phase (Nealon et al., Clin. Chem. 26: 1165-116...
متن کاملDesign of therapeutic chelating agents.
The successful design of orally active non-toxic selective metal chelators is a much sought-after goal. In order to identify an ideal chelator for clinical use, a range of specifications must be considered, such as metal selectivity and affinity, kinetic stability of the complex, bioavailability and toxicity. In this overview the comparative properties of ligands capable of endowing complexes w...
