Abstract:
Various toxicological and metabolic interactions have been reported to exist between arsenic and selenium. In the present study, synthetic seleno-arsenic compounds, potentially suitable for probing metabolic interactions between these two elements, were prepared and tentatively characterized by using high-performance liquid chromatography (HPLC)-electrospray tandem mass spectrometry and HPLC-inductively coupled plasma mass spectrometry. In analogy to the recently identified thio-arsenic species, which can be prepared from their corresponding oxo-arsenic species via reaction with H(2)S, the seleno-arsenic compounds were also derived from oxo-arsenic compounds via reaction with H(2)Se. Figure H(2)Se bubbled into solutions containing oxo-arseno-sugars converts them into their seleno-arseno-sugar analogues.
