  • Title: General inverse solid-phase synthesis method for C-terminally modified peptide mimetics.
    Author: Sasubilli R, Gutheil WG.
    Journal: J Comb Chem; 2004; 6(6):911-5. PubMed ID: 15530118.
    Abstract:
    Peptide mimetics are of considerable interest as bioactive agents and drugs. C-terminally modified peptide mimetics are of particular interest given the synthetic versatility of the carboxyl group and its derivatives. A general approach to C-terminally modified peptide mimetics, based on a urethane attachment strategy and amino acid t-butyl ester-based N-to-C peptide synthesis, is described. This approach is compatible with the reaction conditions generally employed for solution-phase peptide mimetic synthesis. To develop and demonstrate this approach, it was employed for the solid-phase synthesis of peptide trifluoromethyl ketones, peptide boronic acids, and peptide hydroxamic acids. The development of a versatile general approach to C-terminally modified peptides using readily available starting materials provides a basis for the combinatorial and parallel solid-phase synthesis of these peptide mimetic classes for bioactive agent screening and also provides a basis for the further development of solid-phase C-terminal functional group elaboration strategies.
