The metabolic stability of peptides containing a mixed sequence of alpha-aminoxy acids and alpha-amino acids is significantly improved compared to peptides composed of only natural alpha-amino acids. The introduction of an alpha-aminoxy acid into peptide chain dramatically improves the stability of the amide bonds immediately before and after it. These peptides containing alpha-aminoxy acids represent excellent structural scaffold for the design of metabolically stable and biologically active peptides.

    ABSTRACT: α-Aminoxy peptide AxyP1 has been reported to form synthetic chloride channel in living cells, thus it may have therapeutic potential for the treatment of diseases associated with chloride channel dysfunction. However, this study revealed significant gastrointestinal (GI) instability and extensive hepatic metabolism of AxyP1. To improve its GI and metabolic stability, structural modifications were conducted by replacing the isobutyl side chains of AxyP1 with methyl group (AxyP2), hydroxymethyl group (AxyP3), 4-aminobutyl group (AxyP4) and 3-carboxyl propyl group (AxyP5). Compared with AxyP1 (41 and 47 % degradation), GI stability of the modified peptides was significantly improved by 8-fold (AxyP2), 9-fold (AxyP3) and 12-fold (AxyP5) with no degradation for AxyP4 in simulated gastric fluid within 1 h, and by 12-fold (AxyP2) and 9-fold (AxyP3) with no degradation for AxyP4 and AxyP5 in simulated intestinal fluid within 3 h, respectively. The hepatic metabolic stability of the four modified peptides within 30 min in rat liver S9 preparation was also improved significantly with no metabolism of AxyP5 and threefold (AxyP2 and AxyP4) and eightfold (AxyP3) less metabolism compared with AxyP1 (39 % metabolism). Unlike hydrolysis as the major metabolism of peptides of natural α-amino acids, oxidation mediated by the cytochrome P450 enzymes, especially CYP3A subfamily, to form the corresponding mono-hydroxyl metabolites was the predominant hepatic metabolism of the five α-aminoxy peptides tested. The present findings demonstrate that structural modification can significantly improve the GI and metabolic stability of α-aminoxy peptides and thus increase their potential for therapeutic use in the treatment of chloride channel related diseases.

    ABSTRACT: Over the past few decades, scientific research has been focused on developing peptide/protein-based therapies to treat various diseases. With the several advantages over small molecules, including high specificity, high penetration, ease of manufacturing, peptides have emerged as promising therapeutic molecules against many diseases. However, one of the bottlenecks in peptide/protein-based therapy is their toxicity. Therefore, in the present study, we developed in silico models for predicting toxicity of peptides and proteins.

    ABSTRACT: Peptidomimetics represent an important field in chemistry, pharmacology and material science as they circumvent the limitations of traditional peptides used in therapy. Self-structural organizations such as turns, helices, sheets and loops can be accessed by chemical modifications of amino acids or peptides. In-depth structural and conformational analysis and structure-activity relationships (SAR) offer a way to establish peptidomimetic libraries. Herein, we review recent developments in peptidomimetics that are formed via heteroatom replacement within the native amino acid backbone. Each sub-section describes structural features, utility and preparative methods.
