Inorganic concepts relevant to metal binding, activity, and toxicity in a biological system

摘要

Selected physical and inorganic concepts and factors which might be important in assessing and/or understanding the fate and disposition of metal compounds in a biological environment are reviewed. The stereochemistry (geometry), thermodynamic stability, redox properties, and intrinsic reactivity/lability are properties of metal compounds which can have a major influence on metal-target binding and on the eliciting of activity/toxicity. Concepts and factors are illustrated with appropriate examples where possible. Efforts to correlate the toxicity of metal compounds with a suitable indicator of toxicity should be expanded to include other parameters or combinations of parameters.
