Thiolinduced reduction of antimony(V) into antimony(III ...

Gluthathione (GSH) has been previously shown to promote the reduction of pentavalent antimony (Sb(V)) into the more toxic trivalent antimony (Sb(III)) in the antimonial drug, meglumine antimonate. However, this reaction occurred at acidic pH (pH 5) but not at the pH of the cytosol (pH ) in which GSH is encountered. The aim of the present study was to further .
