Peptidomimetics: Fmoc solid-phase pseudopeptide synthesis

Methods in Molecular Biology

Abstract

Peptidomimetic modifications or cyclization of linear peptides are frequently used as attractive methods to provide more conformationally constrained and thus more stable and bioactive peptides. Among numerous peptidomimetic approaches described recently in the literature, particularly attractive are pseudopeptides or peptide bond surrogates in which peptide bonds have been replaced with other chemical groups. In these peptidomimetics the amide bond surrogates possess three-dimensional structures similar to those of natural peptides, yet with significant differences in polarity, hydrogen bonding capability, and acid-base character. The introduction of such modifications to the peptide sequence is expected to completely prevent protease cleavage of amide bond and significantly improve peptides' metabolic stability. In this chapter we consider Fmoc solid-phase synthesis of peptide analogs containing the amide surrogate that tend to be isosteric with the natural amide. This includes synthesis of peptidosulfonamides, phosphonopeptides, oligoureas, depsides, depsipeptides, and peptoids.

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.
