J Org Chem 2024; 89:4760-4767. [PMID: 38544408 PMCID: PMC11002926 DOI: 10.1021/acs.joc.3c02991] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2023] [Revised: 03/07/2024] [Accepted: 03/15/2024] [Indexed: 04/06/2024]
Abstract
Although the construction of peptides with well-defined three-dimensional structures and predictable functions, including biological activity, using conformationally constrained β-amino acids has been shown to be a very successful strategy, their broad application is limited by access to the appropriate building blocks. In particular, trans- and cis-stereoisomers of 2-aminocyclopentanecarboxylic acid (ACPC) are of high interest. The scalable synthesis of all four stereoisomers of Fmoc derivatives of ACPC is presented with NMR-based analysis methods for their enantiomeric purity.

Abstract
The entry of the SARS-CoV-2 virus into a human host cell begins with the interaction between the viral spike protein (S protein) and human angiotensin-converting enzyme 2 (hACE2). Therefore, a possible strategy for the treatment of this infection is based on inhibiting the interaction of the two abovementioned proteins. Compounds that bind to the SARS-CoV-2 S protein at the interface with the alpha-1/alpha-2 helices of ACE2 PD Subdomain I are of particular interest. We present a stepwise optimisation of helical peptide foldamers containing trans-2-aminocylopentanecarboxylic acid residues as the folding-inducing unit. Four rounds of optimisation led to the discovery of an 18-amino-acid peptide with high affinity for the SARS-CoV-2 S protein (Kd = 650 nM) that inhibits this protein-protein interaction with IC50 = 1.3 µM. Circular dichroism and nuclear magnetic resonance studies indicated the helical conformation of this peptide in solution.

Abstract
Suppressors of cytokine signaling 1 (SOCS1) protein, a negative regulator of the Janus kinase (JAK)-signal transducer and activator of transcription (STAT) pathway, possesses a small kinase inhibitory region (KIR) involved in the inhibition of JAK kinases. Several studies showed that mimetics of KIR-SOCS1 can be potent therapeutics in several disorders (e.g., neurological, autoimmune or cardiovascular diseases). In this work, starting from a recently identified cyclic peptidomimetic of KIR-SOCS1, icPS5(Nal1), to optimize the peptide structure and improve its biological activity, we designed novel derivatives, containing crucial amino acids substitutions and/or modifications affecting the ring size. By combining microscale thermophoresis (MST), Circular Dichroism (CD), Nuclear Magnetic Resonance (NMR) and computational studies, we showed that the cycle size plays a key role in the interaction with JAK2 and the substitution of native residues with un-natural building blocks is a valid tool to maintain low-micromolar affinity toward JAK2, greatly increasing their serum stability. These findings contribute to increase the structural knowledge required for the recognition of SOCS1/JAK2 and to progress towards their conversion into more drug-like compounds.

Miniproteins in medicinal chemistry. Bioorg Med Chem Lett 2022; 71:128806.

Abstract
Miniproteins exhibit great potential as scaffolds for drug candidates because of their well-defined structure and good synthetic availability. Because of recently described methodologies for their de novo design, the field of miniproteins is emerging and can provide molecules that effectively bind to problematic targets, i.e., those that have been previously considered to be undruggable. This review describes methodologies for the development of miniprotein scaffolds and for the construction of biologically active miniproteins.

Abstract
The potential of miniproteins in the biological and chemical sciences is constantly increasing. Significant progress in the design methodologies has been achieved over the last 30 years. Early approaches based on propensities of individual amino acid residues to form individual secondary structures were subsequently improved by structural analyses using NMR spectroscopy and crystallography. Consequently, computational algorithms were developed, which are now highly successful in designing structures with accuracy often close to atomic range. Further perspectives include construction of miniproteins incorporating non-native secondary structures derived from sequences with units other than α-amino acids. Noteworthy, miniproteins with extended structures, which are now feasibly accessible, are excellent scaffolds for construction of functional molecules.

Abstract
The key issue in the research on foldamers remains the understanding of the relationship between the monomers structure and conformational properties at the oligomer level. In peptidomimetic foldamers, the main goal of which is to mimic the structure of proteins, a main challenge is still better understanding of the folding of peptides and the factors that influence their conformational stability. We probed the impact of the modification of the peptide periphery with trans- and cis-2-aminocyclopentanecarboxylic acid (ACPC) on the structure and stability of the model coiled-coil using circular dichroism (CD), analytical ultracentrifugation (AUC) and two-dimensional nuclear magnetic resonance spectroscopy (2D NMR). Although, trans-ACPC and cis-ACPC-containing mutants differ by only one peripheral stereogenic center, their conformational stability is strikingly different.

Abstract
A new miniprotein built from three helices, including one structure based on the ααβαααβ sequence pattern was developed. Its crystal structure revealed a compact conformation with a well-packed hydrophobic core of unprecedented structure. The miniprotein formed dimers that were stabilized by the interaction of their hydrophobic surfaces.

Abstract
MDM4 is a homologue of MDM2, serving cooperatively as the negative regulator of tumor suppressor p53. Under the shadow of MDM2 inhibitors, limited efforts had been put into the discovery of MDM4 modulators. Recent studies of the experimental drug ALRN-6924, a dual MDM4 and MDM2 inhibitor, suggest that concurrent inhibition of MDM4 and MDM2 might be beneficial over only MDM2 inhibition. In view of the present research progress, we summarized published inhibitors of MDM4/p53 interactions including both peptide-based compounds and small molecules. Cocrystal structures of ligand/MDM4 complexes have been examined, and their structural features were compiled and compared in order to show the molecular basis required for high MDM4 binding affinities. Representative examples of small-molecule MDM4 inhibitors were discussed, followed by clinical results of ALRN-6924, together, providing a consolidated reference for further development of MDM4 inhibitors, either dual or selective.

Abstract
The construction of β-amino acid-containing peptides that fold to tertiary structures in solution remains challenging. Two model miniproteins, namely, Trp-cage and FSD, were scanned using a constrained β-amino acid in order to evaluate its impact on the folding process. Relationships between forces stabilizing the miniprotein structure and conformational stability of analogues were found. The possibility of a significant increase of the conformational stability of the studied miniproteins by substitution with the β-amino acid at the terminus of a helix is shown. On the basis of these results, β-amino acid containing-peptide analogs with helical fragments substantially altered by the incorporation of several constrained β-amino acids were designed, synthesized and evaluated with respect to their structure and stability. The smallest known β-amino acid-containing peptide with a well-defined tertiary structure is described.
