Cobalt–alkyne complexes are a new class of potent cytotoxic drugs. The lead compound [2-acetoxy-(2-propynyl)benzoate]hexacarbonyldicobalt (Co-ASS) showed high effects on several human cancer cell lines. In order to evaluate further the in-vitro properties and reactivity of this substance we performed stability and protein binding studies and investigated the interaction of this complex with 1,2-ethanedithiol,...
Gamma-glutamylcysteine synthetase (γ-GCS) catalyzes the first, rate-limiting step in the biosynthesis of glutathione (GSH). To evaluate the protective role of cellular GSH against arsenic-induced oxidative stress in Caenorhabditis elegans (C. elegans), we examined the effect of the C. elegans ortholog of GCS(h), gcs-1, in response to inorganic arsenic exposure. We have evaluated the responses of wild-type...
