  Design and synthesis of broad-Based mono- and bi- cyclic inhibitors of FIV and HIV proteases

  摘要：

  Based on the substrate transition state and our strategy to tackle the problem of drug resistance, a series of HIV/FIV protease (HIV/FIV PR) monocyclic inhibitors incorporating a 15- or 17-membered macrocycle with an equivalent P3 or P3' group and a unique unnatural amino acid, (2R, 3S)-3-amino-2-hydroxy-4-phenylbutyric acid, have been designed and synthesized. In addition, based on the structure of TL3 with small P3/P3' group, we have synthesized two conformationally restricted bicyclic inhibitors containing the macrocycle, which mimic the P1/P1'-P3/P3' tripeptide [Phe-Val-Ala] of TL3. We have found that the contribution of the macrocycle in our monocyclic inhibitors is important to the overall activity, but the ring size does not affect the activity to a significant extent. Several inhibitors that were developed in this work, exhibit low nanomolar inhibitory activity against the wild-type HIV/FIV PR and found to be highly effective against some drug-resistant as well as TL3-resistant mutants of HIV PRs. Compound 15, in particular, is the most effective cyclic inhibitor in hand to inhibit FIV replication in tissue culture at a concentration of 1.0 mug/mL (1.2 muM). (C) 2003 Elsevier Science Ltd.

  potency against the HIV protease in vitro. Within this series, 31 (VLE776) is the most effective inhibitor against FIV protease, and it contains Phe at P3, but no P3' residue. VLE776 also exhibited potent antiviral activities against the drug-resistant HIV mutants (G48V and V82F) and the TL3-resistant HIV mutants. Explanation of the inhibition activities was described. In addition, a new strategy was described

  There is provided a novel process for the preparation of a dipeptide represented by the formula: ##STR1## wherein Ar represents an aromatic group; R.sup.1 represents a hydrogen atom, an alkyl group or an aryl group; R.sup.2 represents a hydrogen atom, an alkyl group or an aromatic group; Y represents a hydroxy group, an amino group or an acylamino group, which comprises subjecting a .beta.-lactam compound represented by the formula: ##STR2## wherein Ar, R.sup.1 and R.sup.2 have the same meanings as defined above, and X represents a hydroxy group, an amino group or an acylamino group, an azido group or a benzyloxy group, to hydrogenolysis in the presence of a catalyst. The process can be practiced without any complicated procedure as seen in the conventional processes for the preparation of peptides.

  N-Ac-DELTA-Phe-AA form labile complexes with Mg(II) ions. Potentiometric titration data show that the carboxyl group of the dehydrodipeptide in them scarcely participates in complexation, unlike the complexes with Ca(II) ions, The hydrogenation of these complexes over Pd/C occurs asymmetrically, the diastereomeric excess being as high as 58%.
