  Novel tetrahydropyran-based peptidomimetics from a bioisosteric transformation of a tripeptide. Evidence of their activity at melanocortin receptors

  摘要：

  We have prepared novel peptidomimetics based on a 2,4,6-trisubstituted tetrahydropyran. This scaffold was constructed in an isosteric transformation using conceptual constraints imposed on a tripeptide moiety involving O-i'-C-1(+1)gamma and O-i'-Ni+2 formal cyclization modes. A series of regioselective transformations commencing with a substituted dihydropyran-4-one readily provided the required analogues. Specific tetrahydropyrane analogues modeled on PheArgTrp as a truncated version of the melanocortin receptor message sequence, showed activity at the melanocortin receptors MC4R and MC1R. Thus, the 2,4,6-trisubstituted tetrahydropyran scaffold has provided a potentially useful peptidomimetic lead, and conceptual cyclization of peptide moieties can offer a valuable design strategy in peptidomimetic research.
