摘要

Peptidyl a-keto amides have been synthesized and tested as inhibitors of the cysteine protease calpain. A stereospecific synthesis was devised in which Cbz-dipeptidyl-a-hydroxy amides were oxidized with TEMPOhypochlorite to the corresponding a-keto amides. This oxidation was accomplished in good yields and without epimerization of the chiral center adjacent to the ketone. The potent inhibition of porcine calpain I by the L, L diastereomers, ...
