• Cyclohexyloxycarbonyl based orthogonal solid phase peptide synthesis in Boc chemistry

  Application of N-cyclohexyloxycarbonyl (Choc) protection in Boc chemistry on solid phase provides a new possibility for the preparation of protected peptide fragments. A Choc/OcHex protection scheme allows also the assembly of cyclic lactam peptides linked to the resin through the C-terminus. Choc protection is stable under the 1M TMSOTf-thioanisole/TFA cleavage condition at 0 degrees C, but it is removable by anhydrous HF. We have utilized cyclohexyloxycarbonyl as an orthogonal protecting group for the synthesis of a i) bicyclic epitope peptide of glycoprotein D of HSV 1 on BHA resin and ii) fully protected hexapeptide involved in protein transport on Merrifield resin.

  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.

  The oral absorption profile of a family of azole-based ET(A)-selective antagonists has been improved through a rational series of structural modifications which were suggested by analysis of the physicochemical parameter Delta log P. Comparison of urea 2 with a series of well-absorbed compounds using Delta log P analysis suggested that 2 has an excess capacity for forming hydrogen bonds with solvent. A series of urea modifications were explored as a means of reducing H-bonding capacity while maintaining affinity for the ET(A)-receptor. The correlation between Delta log P values and absorption in an intraduodenal (id) bioavailability model was good; this strategy uncovered replacements for each of the urea NH groups which simultaneously improve both potency and drug absorption. A combination of these optimized modifications produces carbamate 16h, a highly-selective ET(A) antagonist with a potency/bioavailability profile consistent with an oral route of administration.
