of regioisomers. Lipoic acid and N,N′-dibenzoylcystine dimethyl ester were oxidized readily under similar conditions. Although isolated yields of the product thiolsulfinates were generally modest, these experiments demonstrate that the method nevertheless has preparative value because of its mild conditions. The results also confirm the possibility that cyclic seleninate esters could catalyze the further

thiol-selective cross-linkers, for example, modify all accessible thiols, but only form cross-links between a subset. The resulting terminal "dead-end" modifications of lone thiols are toxic, confound cross-linking-based studies of macromolecular structure, and are an undesired, and currently unavoidable, byproduct in polymer synthesis. Using the thiol pair of Cu/Zn-superoxide dismutase (SOD1), we demonstrated

Dipeptide-derived alpha-keto-amide compounds with potent calpain inhibitory activity have been identified. These reversible covalent inhibitors have IC50 values down to 25 nM and exhibit greatly improved activity in muscle cells compared to the reference compound MDL28170. Several novel calpain inhibitors have shown positive effects on histological parameters in an animal model of Duchenne muscular dystrophy demonstrating their potential as a treatment option for this fatal disease.
