  Structure-Based Design, Synthesis, and Biological Evaluation of Irreversible Human Rhinovirus 3C Protease Inhibitors. 2. Peptide Structure−Activity Studies

  摘要：

  The structure-based design, chemical synthesis, and biological evaluation of various peptide-derived human rhinovirus (HRV) 3C protease (3CP) inhibitors are described. These compounds are comprised of an ethyl propenoate Michael acceptor moiety and a tripeptidyl binding determinant. The systematic modification of each amino acid residue present in the binding determinant as well as the N-terminal functionality is described. Such modifications are shown to provide irreversible HRV-14 3CP inhibitors with anti-3CP activities (k(obs)/[I]) ranging from 60 to 280 000 M-1 s(-1) and antiviral EC50's which approach 0.15 mu M. An optimized inhibitor which incorporates several improvements identified by the structure-activity studies is also described. This molecule displays very rapid irreversible inhibition of HRV-14 3CP (k(obs)/[I] = 800 000 M-1 s(-1)) and potent antiviral activity against HRV-14 in cell culture (EC50 = 0.056 mu M). A 1.9 Angstrom crystal structure of an S-alkylthiocarbamate-containing inhibitor complexed with HRV-8 3CP is also detailed.
