The photocatalytic formation-recombinationcycle of thiyl radicals was coupled with the molecular recognitionsteps in the replication cycles.

We selected tyrosine-rich (Y4C) and tryptophan-rich (W4C) peptides for use as electron-transfer agents. The peak for oxidation was based on the oxidations of the phenolic hydroxy groups in Y4C and on the indole rings in W4C. Asialofetuin (ASF) with galactose residues was the protein probe, and a galactose recognition protein, soybean agglutinin (SBA), was the target protein. A protein probe composed of an amino acid and carbohydrate residue was expected to be biocompatible. When voltammetric measurements were performed using a glassy carbon electrode, the oxidation peaks of H6Y4C and ASF-H6Y4C appeared at the same potential. The peak current of ASF-H6Y4C was 4-fold that of H6Y4C because of the stronger adsorption of ASF-H6Y4C onto the electrode. The electrode response of ASF-H6Y4C with SBA was half that of ASF-H6Y4C alone. By contrast, the peak current of ASF-Y4CH6 was higher than that of ASF-H6Y4C, which was the result of a greater degree of contact between the Y4C moieties and an electrode. On the other hand, the voltammetric behaviors of ASF with W4C and a His-tag were similar to those with Y4C and a His-tag. The sensitivity of SBA using ASF-Y4CH6 was at the 10(-13) M level. To confirm the function of the sensing system, measurements were performed in human serum with SBA and ASF-Y4CH6. When SBA was added, the serum had a concentration that ranged between 5.0x10(-13) and 4.0x10(-12) M, and the amount of SBA that could be recovered ranged from 97 to 101%. Consequently, this system could be applied to the detection of SBA in serum.}, keywords = {tryptophan; tyrosine; Electron-transfer peptid; Asialofetuin; Soybean agglutinin}, year = {2020}, eissn = {1521-4109} } @article{MTMT:31422293, title = {Micro-flow synthesis of beta-amino acid derivatives via a rapid dual activation approach}, url = {https://m2.mtmt.hu/api/publication/31422293}, author = {Sugisawa, Naoto and Nakamura, Hiroyuki and Fuse, Shinichiro}, doi = {10.1039/d0cc01403f}, journal-iso = {CHEM COMMUN}, journal = {CHEMICAL COMMUNICATIONS}, volume = {56}, unique-id = {31422293}, issn = {1359-7345}, abstract = {Rapid dual activation (<= 3.3 s) of both beta-amino acid N-carboxy anhydride and alkyl chloroformate for the synthesis of a beta-amino acid-derived scaffold was demonstrated.

Nevertheless, they often suffer from a weak stability in polar solvents because they exhibit a mixed hydrogen-bond network resulting in a small macrodipole. In this work, stable and functionalizable 12/10-helices were developed by alternating a highly constrained beta(2, 3, 3)-trisubstituted bicyclic amino acid (S)-1-aminobicyclo[2.2.2]octane-2-carboxylic acid ((S)-ABOC) and an acyclic substituted beta-homologated proteinogenic amino acid (l-beta(3)-hAA). Based on NMR spectroscopic analysis, it was shown that such mixed beta-peptides display well-defined right-handed 12/10-helices in polar, apolar, and chaotropic solvents; that are, CD3OH, CDCl3, and [D-6]DMSO, respectively. The stability of the hydrogen bonds forming the C-10 and C-12 pseudocycles as well as the benefit provided by the use of the constrained bicyclic ABOC versus typical acyclic beta-amino acids sequences when designing 12/10-helix were investigated using NH/ND NMR exchange experiments and DFT calculations in various solvents. These studies showed that the beta(3)-hAA/(S)-ABOC helix displayed a more stable hydrogen-bond network through specific stabilization of the C-10 pseudocycles involving the bridgehead NH of the ABOC bicyclic scaffold.}, keywords = {helical structures; PROTEIN MODELS; BETA-PEPTIDE; foldamer; bicyclic beta-amino acids; helical stabilization}, year = {2018}, eissn = {1521-3765}, pages = {18795-18800} } @article{MTMT:27106548, title = {An NMR Method To Pinpoint Supramolecular Ligand Binding to Basic Residues on Proteins}, url = {https://m2.mtmt.hu/api/publication/27106548}, author = {Hogeweg, Anna and Sowislok, Andrea and Schrader, Thomas and Beuck, Christine}, doi = {10.1002/anie.201707950}, journal-iso = {ANGEW CHEM INT EDIT}, journal = {ANGEWANDTE CHEMIE-INTERNATIONAL EDITION}, volume = {56}, unique-id = {27106548}, issn = {1433-7851}, year = {2017}, eissn = {1521-3773}, pages = {14758-14762} } @article{MTMT:26876392, title = {Dynamic Covalent Chemistry of Aldehyde Enamines: Bi-III- and Sc-III-Catalysis of Amine-Enamine Exchange}, url = {https://m2.mtmt.hu/api/publication/26876392}, author = {Zhang, Yang and Xie, Sheng and Yan, Mingdi and Ramstroem, Olof}, doi = {10.1002/chem.201702363}, journal-iso = {CHEM-EUR J}, journal = {CHEMISTRY-A EUROPEAN JOURNAL}, volume = {23}, unique-id = {26876392}, issn = {0947-6539}, year = {2017}, eissn = {1521-3765}, pages = {11908-11912} }
