  Tripeptide Aldehyde Inhibitors of Human Rhinovirus 3C Protease:  Design, Synthesis, Biological Evaluation, and Cocrystal Structure Solution of P₁ Glutamine Isosteric Replacements

  摘要：

  The investigation of tripeptide aldehydes as reversible covalent inhibitors of human rhinovirus (HRV) 3C protease (3CP) is reported. Molecular models based on the apo crystal structure of HRV-14 3CP and other trypsin-like serine proteases were constructed to approximate the binding of peptide substrates, generate transition state models of P-1-P-1' amide cleavage, and propose novel tripeptide aldehydes. Glutaminal derivatives have limitations since they exist predominantly in the cyclic hemiaminal form. Therefore, several isosteric replacements for the P-1 carboxamide side chain were designed and incorporated into the tripeptide aldehydes. These compounds were found to be potent inhibitors of purified HRV-14 3CP with K(i)s ranging from 0.005 to 0.64 mu M. Several have low micromolar antiviral activity when tested against HRV-14-infected H1-HeLa cells. The N-acetyl derivative 3 was also shown to be active against HRV serotypes 2, 16, and 89. High-resolution cocrystal structures of HRV-8 3CP, covalently bound to compounds 3, 15, and 16, were solved. These cocrystal structures were analyzed and compared with our original HRV-14 3CP-substrate and inhibitor models.

  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.
