Takeuchi, Aoi;Itoh, Hiroaki;Inoue, Masayuki research published 《 ¹⁸O/¹⁶O-Encoding strategy for microscale stereochemical determination of peptidic natural products》, the research content is summarized as follows. The demand for more efficient methods of establishing the undetermined stereochemistries of peptidic natural products continues unabated. A new method for microscale stereochem. determination was devised by integrating solid-phase synthesis, split-and-mix randomization, ¹⁸O/¹⁶O-encoding of D/L-configurations, tandem mass spectrometry, and biol. evaluation. Here we applied gramicidin A as the mol. for a blind test. Gramicidin A and its 31 diastereomers were randomly prepared in microgram scale with ¹⁸O/¹⁶O-stereochem. encoding and subjected to MS/MS-structural determination and cytotoxicity assay. Only the parent gramicidin A was selected from among the 32 stereoisomers, validating the high reliability of the present strategy.

Myostatin is a key neg. regulator of skeletal muscle growth, and myostatin inhibitors are attractive tools for the treatment of muscular atrophy. Previously, we reported a series of 14-29 mer peptide myostatin inhibitors, including a potent derivative MIPE-1686, a 16-mer N-terminal-free L-peptide with three unnatural amino acids and a propensity to form β-sheets. However, the biol. stability in vivo of MIPE-1686 is a concern for its development as a drug. In the present study, to develop a more stable myostatin inhibitory D-peptide (MID), various retro-inverso versions of a 16-mer peptide were synthesized. Among these, an arginine-containing derivative, MID-35 shows a potent and equivalent in vitro myostatin inhibitory activity equivalent to that of MIPE-1686 and considerable stability against biodegradation The in vivo potency of MID-35 to increase tibialis anterior muscle mass in mice is significantly enhanced over that of MIPE-1686 and MID-35 can serve as a new entity for the prolonged inactivation of myostatin in skeletal muscle.

Soerensen, Kasper K.;Mishra, Narendra K.;Paprocki, Maciej P.;Mehrotra, Amit;Jensen, Knud J. research published 《 High-Performance Reversed-Phase Flash Chromatography Purification of Peptides and Chemically Modified Insulins》, the research content is summarized as follows. Preparative reversed-phase HPLC is the established method for the purification of peptides, but has significant limitations. We systematically investigated the use of high-performance reversed-phase flash chromatog. (HPFC) to rapidly purify laboratory-scale quantities of crude, synthetic peptides and chem. modified insulins. We demonstrated these methods for a diverse set of peptides, including short, medium, and long peptides. Depending on the purity profile of the peptide, HPFC can be used either as the sole purification method, or as a pre-purification method prior to final HPLC purification Furthermore, HPFC is suitable for the purification of peptides that are not fully in solution We provide guidelines for the HPFC of synthetic peptides and small proteins, including the choice of columns, eluents, and gradients. We believe that HPFC is a valuable alternative to HPLC purification of peptides and small proteins.

Sheng, Le;Jin, Yulong;Hou, Huiqing;Huang, Yanyan;Zhao, Rui research published 《 Hydrazone bond-oriented molecularly imprinted nanocomposites for the selective separation of protein via the well-defined recognition sites》, the research content is summarized as follows. The development of hydrazone bond-oriented epitope imprinting strategy is reported to synthesize the polymeric binders for the selective recognition of a protein-β₂-microglobulin through either its N- or C-terminal epitope. The dynamic reversibility of hydrazone bond facilitated not only the oriented assembly of the template peptide hydrazides onto the substrate but also the efficient removal of them from the imprinted cavities. The well-defined surface imprinted layer was successfully constructed through the precise control over the polymerization of silicate esters. Binding performance of the C-terminal peptide imprinted nanocomposite was significantly improved after tuning the non-covalent interactions using the sequence-matching aromatic co-monomers. The dissociation constant (K_d) between the optimized nanocomposite and epitope peptide was 0.5 μmol L^-1. The nanomaterial was utilized for the selective extraction and determination of β₂-microglobulin from human urine by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) and HPLC-UV with satisfied recoveries of 93.1-112.3% in a concentration range 1.0-50.0 μg·mL^-1.

Sakamoto, Kentarou;Michibata, Junya;Hirai, Yusuke;Ide, Akiko;Ikitoh, Asuka;Takatani-Nakase, Tomoka;Futaki, Shiroh research published 《 Potentiating the Membrane Interaction of an Attenuated Cationic Amphiphilic Lytic Peptide for Intracellular Protein Delivery by Anchoring with Pyrene Moiety》, the research content is summarized as follows. We previously reported an approach for intracellular protein delivery by attenuating membrane-lytic activity of cationic amphiphilic peptides on cell surfaces. HAad is one such peptides that cytosolically delivers proteins of interest, including antibodies, by stimulating their endosomal escape. Addnl., HAad elicits ruffling of cell membrane, accompanied by transient membrane permeabilization, allowing for the efficient cytosolic translocation of proteins. In this study, we prepared a conjugate of HAad with pyrenebutyric acid as a membrane-anchoring unit (pBu-HAad). pBu-HAad demonstrated protein delivery into cells with only 1/20 concentration of HAad. However, the conjugates with cholesteryl hemisuccinate and aliphatic fatty acids (C = 3, 6, and 10) did not yield such marked effects. The results of time-course and inhibitor studies suggest that the membrane anchoring of HAad by a pyrene moiety leads to enhanced peptide-membrane interaction and to loosen lipid packing, thus facilitating cytosolic translocation through membranes.

Ulcerative colitis and Crohn′s disease are forms of inflammatory bowel disease whose incidence and prevalence are increasing worldwide. These diseases lead to chronic inflammation of the gastrointestinal tract as a result of an abnormal response of the immune system. Recent studies positioned Cortistatin, which shows low stability in plasma, as a candidate for IBD treatment. Here, using NMR structural information, we design five Cortistatin analogs adopting selected native Cortistatin conformations in solution One of them, A5, preserves the anti-inflammatory and immunomodulatory activities of Cortistatin in vitro and in mouse models of the disease. Addnl., A5 displays an increased half-life in serum and a unique receptor binding profile, thereby overcoming the limitations of the native Cortistatin as a therapeutic agent. This study provides an efficient approach to the rational design of Cortistatin analogs and opens up new possibilities for the treatment of patients that fail to respond to other therapies.

Paprocki, Maciej P.;Rasmussen, Jakob E.;Soerensen, Kasper K.;Jensen, Knud J. research published 《 Safety-catch linkers for Fmoc solid-phase synthesis of peptide thioesters and hydrazides by amide-to-imide activation》, the research content is summarized as follows. The use of C-terminal peptide thioesters and hydrazides in synthetic protein chem. has inspired the search for optimal solid-phase peptide synthesis (SPPS) strategies for their assembly. However, peptide thioesters are not directly accessible by conventional Fmoc-SPPS (Fmoc = 9-fluorenylmethoxycarbonyl) owing to the nucleophilicity of the secondary amine required for Fmoc removal. Here, we report the mild and effective activation of the pGlu linker and a new safety-catch linker that was used for the convenient synthesis of peptide thioesters and hydrazides via efficient amide-to-imide activation followed by nucleophilic displacement.
