Deciphering the Synthetic and Refolding Strategy of a Cysteine-Rich Domain in the Tumor Necrosis Factor Receptor (TNF-R) for Racemic Crystallography Analysis and d-Peptide Ligand Discovery. ACS BIO & MED CHEM AU 2024; 4:68-76. [PMID: 38404743 PMCID: PMC10885103 DOI: 10.1021/acsbiomedchemau.3c00060] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 09/13/2023] [Revised: 11/14/2023] [Accepted: 11/15/2023] [Indexed: 02/27/2024]
Abstract
Many cell-surface receptors are promising targets for chemical synthesis because of their critical roles in disease development. This synthetic approach enables investigations by racemic protein crystallography and ligand discovery by mirror-image methodologies. However, due to their complex nature, the chemical synthesis of a receptor can be a significant challenge. Here, we describe the chemical synthesis and folding of a central, cysteine-rich domain of the cell-surface receptor tumor necrosis factor 1 which is integral to binding of the cytokine TNF-α, namely, TNFR-1 CRD2. Racemic protein crystallography at 1.4 Å confirmed that the native binding conformation was preserved, and TNFR-1 CRD2 maintained its capacity to bind to TNF-α (KD ≈ 7 nM). Encouraged by this discovery, we carried out mirror-image phage display using the enantiomeric receptor mimic and identified a d-peptide ligand for TNFR-1 CRD2 (KD = 1 μM). This work demonstrated that cysteine-rich domains, including the central domains, can be chemically synthesized and used as mimics for investigations.

Abstract
Peptides act as biological mediators and play a key role of various physiological activities. Sulfur-containing peptides are widely used in natural products and drug molecules due to their unique biological activity and chemical reactivity of sulfur. Disulfides, thioethers, and thioamides are the most common motifs of sulfur-containing peptides, and they have been extensively studied and developed for synthetic methodology as well as pharmaceutical applications. This review focuses on the illustration of these three motifs in natural products and drugs, as well as the recent advancements in the synthesis of the corresponding core scaffolds.

Abstract
Cone snails produce venom that contains diverse groups of peptides (conopeptides/conotoxins) and display a wide mass range, high rate of posttranslational modifications, and many potential pharmacological targets. Here we employ a proteogenomic approach to maximize conopeptide identification from the injected venom of Conus purpurascens. mRNA sequences from C. purpurascens venom ducts were assembled into a search database and complemented with known sequences and de novo approaches. We used a top-down peptidomic approach and tandem mass spectrometry identification to compare injected venom samples of 27 specimens. This intraspecific analysis yielded 543 unique conopeptide identifications, which included 33 base conopeptides and their toxiforms, 21 of which are novel. The results reveal two distinct venom profiles with different synergistic interactions to effectively target neural pathways aimed to immobilize prey. These venom expression patterns will aid target prediction, a significant step toward developing conotoxins into valuable drugs or neural probes. We analyzed the injected venom of 27 specimens of Conus purpurascens. We found 543 unique conopeptide identifications. We identified 21 novel base conopeptides. We found two distinct venom profiles with different synergistic interactions.

Abstract
In this study, l-methionine selenoxide (MetSeO) was used as an oxidant for the construction of peptide disulfide bonds. Excellent yields for various disulfide-containing peptides were achieved via the MetSeO oxidation method in different solvents and on a resin. Most importantly, the construction of disulfide bonds can be performed in the trifluoroacetic acid cocktail used for the cleavage of peptides from the resin, which obviates the steps of peptide purification and lyophilization. This facilitates and simplifies the synthesis of disulfide-containing peptides. Kinetic and mechanistic studies of the reaction between MetSeO and dithiothreitol (DTT, a model compound of dicysteine-containing peptide) show that the reaction is first order in both [MetSeO] and [DTT], and a reaction mechanism is proposed that can help us gain insights into the reaction of the oxidative synthesis of disulfide bonds via MetSeO oxidation.

Abstract
Over the last few years, short peptides have become a powerful tool in basic and
applied research, with different uses like diagnostic, antimicrobial peptides, human health
promoters or bioactive peptides, therapeutic treatments, templates for peptidomimetic design,
and peptide-based vaccines. In this endeavor, different approaches and technologies
have been explored, such as bioinformatics, large-scale peptide synthesis, omics sciences,
structure-activity relationship studies, and a biophysical approach, among others, seeking to
obtain the shortest sequence with the best activity. The advantage of short peptides lies in
their stability, ease of production, safety, and low cost. There are many strategies for designing
short peptides with biomedical and industrial applications (targeting the structure, length,
charge, or polarity) or as a starting point for improving their properties (sequence data base,
de novo sequences, templates, or organic scaffolds). In peptide design, it is necessary to keep in mind factors
such as the application (peptidomimetic, immunogen, antimicrobial, bioactive, or protein-protein interaction
inhibitor), the expected target (membrane cell, nucleus, receptor proteins, or immune system), and particular
characteristics (shorter, conformationally constrained, cycled, charged, flexible, polymerized, or pseudopeptides).
This review summarizes the different synthetic approaches and strategies used to design new peptide analogs,
highlighting the achievements, constraints, and advantages of each.

Abstract
Bicyclic peptides are attractive scaffolds for the design of potent protein binders and new therapeutics. However, peptide bicycles constrained through disulfide bonds are rarely stable or tolerant to sequence manipulation owing to disulfide isomerization, especially for peptides lacking a regular secondary structure. Herein, we report the discovery and identification of a class of bicyclic peptide scaffolds with ordered but irregular secondary structures. These peptides have a conserved cysteine/proline framework for directing the oxidative folding into a fused bicyclic structure that consists of four irregular turns and a 310 helix (characterized by NMR spectroscopy). This work shows that bicyclic peptides can be stabilized into ordered structures by manipulating both the disulfide bonds and proline-stabilized turns. In turn, this could inspire the design and engineering of multicyclic peptides with new structures and benefit the development of novel protein binders and therapeutics.

Abstract
Existing disulfide-rich peptides, both naturally occurring and de novo designed, only represent a tiny amount of the possible sequence space because natural evolution and de novo design only keep sequences that are structurally approachable by correct disulfide pairings. To bypass this limitation for designing new peptide scaffolds beyond the natural sequence space, we dedicate to developing novel disulfide-rich peptides with predefined disulfide pairing patterns irrelevant to primary sequences. However, most of these designed peptides still suffer from disulfide rearrangements to at least one to three possible isomers. Here, we report a general and reliable strategy for the design and synthesis of a range of structurally diverse cross-link-dense peptide (CDP) scaffolds with two orthogonal disulfide bonds and a bisthioether bridge that are not subject to disulfide isomerizations. Altering the pattern of cysteine and penicillamine generates hundreds of different CDP scaffolds tolerant to extensive sequence manipulations. This work thus provides many useful scaffolds for the design of functional molecules such as protein binders with improved proteolytic stability (e.g., designed by epitope grafting).
