a series of novel amino acids and peptides containing an aziridine ring is described. Their preparation is based on the Gabriel-Cromwell reaction of amino acids or peptides with different 2-bromo acrylates and acrylamides. These products are constituted by a turned scaffold (the aziridine) where two parallel peptidic strands can be grown to produce a β-sheet mimetic.
The coronavirus main protease, M-pro, is considered a major target for drugs suitable to combat coronavirus infections including the severe acute respiratory syndrome (SARS). In this study, comprehensive HPLC- and FRET-substrate-based screenings of various electrophilic compounds were performed to identify potential M-pro inhibitors. The data revealec that the coronaviral main protease is inhibited by aziridine- and oxirane-2-carboxylates. Among the trans-configured aziridine-2.3-dicarboxylates the Gly-Gly-containing peptide 2c was found to be the most potent inhibitor. (c) 2005 Elsevier Ltd. All rights reserved.
