Additionally, their ring structure and constrained conformation reduce the entropic cost upon binding to receptors and other biological targets, leading to higher binding affinity and specificity. However, peptide macrocyclization is often synthetically challenging due to factors such as reduced entropy, oligomer formation, and C-terminal epimerization. The conventional approach for synthesizing cyclic peptides involves the direct coupling of amine and carboxyl termini in the solution phase, using protected side-chain peptides and coupling reagents. Despite this, improving the efficiency of head-to-tail cyclization remains a key challenge. In this study, the cyclization of a de novo octapeptide composed of alternating l- and d-amino acids is optimized, in which the impact of various factors on the cyclization process is examined, including coupling reagents, temperature, heating method, chaotropic agents, solvent, and concentration. This investigation has not only led to the identification of efficient cyclization conditions, but also provides a valuable framework for the cyclization of other challenging peptide sequences. The insights gained in this study contribute to the field of peptide chemistry, expanding the understanding of peptide cyclization reactions.","PeriodicalId":140,"journal":{"name":"ChemBioChem","volume":"26 14","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144214467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, with the advent of advanced gene mining methods, a growing number of halohydrin dehalogenases have been discovered and characterized, revealing a diverse array of new structures and catalytic functions. While halohydrin dehalogenases predominantly exhibit β-regioselectivity in the ring-opening of styrene oxides, a few α-regioselective halohydrin dehalogenases have also been identified. In this study, a new α-regioselective halohydrin dehalogenase, HHDHnsr, is purified and analyzed, and its application in the azide-mediated α-regioselective azidolysis of styrene oxide is explored. The findings highlight the potential of HHDHnsr as α-regioselective biocatalyst for the asymmetric synthesis of β-azidoalcohols, offering valuable insights for the future identification of α-regioselective HHDHs in enzyme mining.","PeriodicalId":140,"journal":{"name":"ChemBioChem","volume":"26 13","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144223812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In contrast, a series of studies show that a variety of d-amino acids also occur in mammals, and amino acid homochirality is not complete. Mammals de novo synthesize most amino acids with l-configuration, but serine and aspartate are converted from l- to d-configuration by endogenous enzymes. In addition to endogenous syntheses of d-amino acids, symbiotic bacteria in mammals chiral-convert amino acids, including alanine, glutamate, proline, and leucine in the intestine, creating a heterochiral inner environment. d-amino acids are distributed in distinctive patterns among organs and have physiological roles in the central nervous, endocrine, and immune systems. Mammals manage such diverse d-amino acids with catabolism and excretion into urine at individual levels. In contrast, at the cellular levels an enantioselection mechanism to regulate chiral homeostasis of amino acids has remained unclear. In protein synthesis, the ribosome has a sophisticated system to eliminate d-amino acids, whereas non-ribosomal synthesis also utilizes d-amino acids. Furthermore, amino acid residues in proteins/peptides can be isomerized post-translationally through enzymatic or spontaneous processes. This manuscript overviews how the chiral balance of free amino acids or residues in proteins is maintained in mammals at the individual and cellular levels.","PeriodicalId":140,"journal":{"name":"ChemBioChem","volume":"26 13","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cbic.202500273","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144214468","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While clinically essential for hypoglycemia rescue, its broader therapeutic applications face limitations due to challenging biophysical properties including poor solubility, strong aggregation tendency, and chemical instability, which currently require lyophilized formulations. Recent advances in peptide engineering and formulation science have enabled the development of next-generation glucagon analogs with enhanced stability and ready-to-use profiles. Moving beyond its classical role in glucose elevation, glucagon is now recognized as a multifunctional metabolic regulator influencing lipid metabolism, energy expenditure, and cardiorenal function. This expanded understanding has driven the development of innovative GCGR-targeting therapies including multi-receptor agonists such as glucagon-like peptide-1 receptor (GLP-1R)/GCGR co-agonists for metabolic disorders and advanced dual-hormone delivery systems. This review examines the evolving pharmacology of glucagon by analyzing: (1) structural optimization and formulation strategies to address physicochemical challenges, (2) innovative delivery technologies, and (3) emerging therapeutic applications in metabolic diseases. Through critical assessment of translational challenges, this work bridges molecular insights with clinical innovation in glucagon-based therapeutics.","PeriodicalId":140,"journal":{"name":"ChemBioChem","volume":" ","pages":"e202500270"},"PeriodicalIF":2.6,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144207257","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The expression and biological functions of CYP are affected by environmental factors, genetic variations, and physiological conditions, which can lead to adverse effects and reduce the therapeutic efficacy of drugs in humans. Therefore, there has been considerable interest in the development of probes that can detect the activity of CYPs in complex living systems. This review explores the recent advancements in our understanding of the structure and function of CYPs. It highlights the need to develop specific probes for various CYP subtypes using nonoptical, fluorescent, and bioluminescent substrates.

The in vitro selectivity of proteins for transition metal ions is largely governed by the Irving–Williams series, which states protein-metal complex stability follows the order Co(II) < Ni(II) < Cu(II) > Zn(II). A de novo protein has been designed that folds in the presence of certain transition metal ions into a monomeric α-helical bundle, with the least stable protein-metal complex being formed with Cu(II). Moreover, when increasing the metal concentration of Cu(II) or Zn(II), more metal ions are incorporated into the protein accompanied by a concurrent decrease in the amount of secondary structure. One reason may be that there is a balance between stability conferred by the coordination of the metal ion(s) and stability conferred by hydrophobic packing of the α-helical bundle. Metals may therefore adopt distorted coordination geometries, or binding of multiple ions may cause distortion of the protein backbone, leading to compromised folding of the protein scaffold, or variable thermal stabilities of the metalloprotein complexes. This protein scaffold therefore contributes to the deciphering of design rules for metal selectivity in proteins.","PeriodicalId":140,"journal":{"name":"ChemBioChem","volume":"26 14","pages":""},"PeriodicalIF":2.6,"publicationDate":"2025-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/cbic.202500322","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144172250","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular, modern advanced techniques with fluorescence microscopes have provided considerable methodological advancements in recent years. Here, a brief description of the basic physical principles of fluorescence detection and its experimental measurement setups are provided. For interacting biomolecules in solution, confocal fluorescence microscopy enables some very effective approaches to characterize binding in complex sample environments and with small sample consumption. In addition to standard techniques with bulk samples in classical spectrometers, applications with single-molecule Förster resonance energy transfer, two-color coincidence detection, and fluorescence correlation spectroscopy are presented. The strength of the more advanced techniques lies in their broad applicability, ranging from fluorescence-based genetically encoded biosensors for use in living cells to the high controllability in the measurement of binding curves even at very low molecule concentrations. The advantages and limitations of the individual techniques are compared and recent state-of-the-art applications are discussed.","PeriodicalId":140,"journal":{"name":"ChemBioChem","volume":" ","pages":"e2500283"},"PeriodicalIF":2.6,"publicationDate":"2025-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144149003","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
