Herein, we show that artificial beta-peptides have the tendency toward homochiral diastereoselective chain elongation. Chain-length-dependent stereochemical discrimination was investigated in the synthesis of foldamers with various side chains and secondary structures. It was found that there is a strong tendency toward the synthesis of homochiral oligomers. The size of the side chain drastically influenced the selectivity of the stereodiscriminative chain-elongation reaction. It is noteworthy that water as the co-solvent increases the selectivity. Such behavior is a novel fundamental biomimetic property of foldamers with a potential of future industrial application.}, keywords = {AMINO-ACIDS; ORIGIN; DESIGN; SECONDARY STRUCTURE; FOLDAMERS; CONFIGURATION; Chemistry; CHIRALITY; diastereoselectivity; asymmetric autocatalysis; CORRELATION-ENERGY; BETA-PEPTIDE; foldamer; CHIRAL MOLECULE; homochiralty}, year = {2017}, eissn = {2191-1363}, pages = {492-496}, orcid-numbers = {Mándity, István/0000-0003-2865-6143; Paragi, Gábor/0000-0001-5408-1748; Fülöp, Ferenc/0000-0003-1066-5287} } @article{MTMT:3257484, title = {Influence of pH and aurate/amino acid ratios on the tuneable optical features of gold nanoparticles and nanoclusters}, url = {https://m2.mtmt.hu/api/publication/3257484}, author = {Csapó, Edit and Ungor, Ditta Anita and Kele, Zoltán and Baranyai, Péter and Deák, Andrea Beáta and Juhász, Ádám and Janovák, László and Dékány, Imre}, doi = {10.1016/j.colsurfa.2017.02.047}, journal-iso = {COLLOID SURFACE A}, journal = {COLLOIDS AND SURFACES A : PHYSICOCHEMICAL AND ENGINEERING ASPECTS}, volume = {532}, unique-id = {3257484}, issn = {0927-7757}, abstract = {Blue-and green-emitting gold nanostructures have been synthesized by spontaneous interactions ofthe tetrachloroaurate anions (AuCl4-) withL-histidine (His) and L-tryptophan (Trp) at 37 degrees C in aqueousmedium. The dominant role of AuCl4-/amino acid molar ratios as well as the pH in the formation ofgold nanoparticles (Au NPs) or nanoclusters (Au NCs) was confirmed by numerous spectroscopic techniques. We demonstrate that without additional reducing agents the His and Trp show different reductionbehaviour with AuCl4-which supports the fact that the unique optical features originate from diversestructures. Because of the pH-dependent complexation and reduction capability of the studied aminoacids the dominant presence of polynuclear fluorescent gold(I) complexes (quantum yield (QY%) similar to 4%) with a well-ordered structure is presumable for His-directed Au system confirmed by mass spectrometry, X-ray diffraction and infrared experiments. The existence of d = 8 nm-sized Au NPs or subnanometer-sized(d < 2 nm) Au NCs (Au3-Au5) that have tuneable blue or green photoluminescence (lambda(emission)= 470-500 nm) was identified in the samples containing Trp depending on the applied AuCl4-/Trp ratios.

The dominant role of AMP:AuCl4− molar ratios in the formation of diverse nanosized Au products was proved. The size, the structure and the unique structure-dependent optical properties of the NPs and NCs were determined based on the results of numerous spectroscopic (UV–vis, fluorescence, infrared, x-ray photoelectron), high resolution electron microscopy (HRTEM) and dynamic light scattering (DLS) techniques. Stabile AMP-Au NPs with diameter of ca. 11 nm and ultra-small AMP-Au NCs having blue fluorescence (λem = 480 nm) were identified. In addition, the AMP-Au NCs have been utilized to develop a selective sensor for the detection of Fe3+ ions in aqueous medium based on fluorescence quenching. Several essential metal ions and anions have been tested but our results clearly supported that dominant quenching was observed only for Fe3+ ions. Based on the determined limit of detection (LOD = 2.0 μM) our system is capable of detecting Fe3+ ions in drinking water. The Stern-Volmer constants (KSV) and various thermodynamic parameters (ΔG, ΔH°, ΔS°, ΔCp) of the quenching process have also been determined by the Stern-Volmer fitting of the fluorescence data in order to better understand the quenching mechanism.}, keywords = {Biosensor; GOLD NANOPARTICLES; fluorescence quenching; Adenosine Monophosphate; gold nanoclusters; Iron ion}, year = {2017}, eissn = {1873-4367}, pages = {135-141}, orcid-numbers = {Ungor, Ditta Anita/0000-0002-7659-0428; Csapó, Edit/0000-0002-6980-9524; Juhász, Ádám/0000-0003-0033-7968; Dékány, Imre/0000-0001-5472-5355} } @article{MTMT:3193426, title = {Loop-F of the alpha-subunit determines the pharmacologic profile of novel competitive inhibitors of GABA(A) receptors}, url = {https://m2.mtmt.hu/api/publication/3193426}, author = {Mihalik, Balázs and Pálvölgyi, Adrienn and Bogár, Ferenc and Megyeri, Katalin and Ling, István and Barkóczy, József and Bartha, Ferenc and Martinek, Tamás and Gacsályi, István and Antoni, Ferenc András}, doi = {10.1016/j.ejphar.2017.01.033}, journal-iso = {EUR J PHARMACOL}, journal = {EUROPEAN JOURNAL OF PHARMACOLOGY}, volume = {798}, unique-id = {3193426}, issn = {0014-2999}, keywords = {GABA; molecular modelling; Nootropic Agents; GABAA antagonists; Extrasynaptic receptors; Loop-F}, year = {2017}, eissn = {1879-0712}, pages = {129-136}, orcid-numbers = {Mihalik, Balázs/0000-0002-4302-7567; Bogár, Ferenc/0000-0002-0611-1452; Martinek, Tamás/0000-0003-3168-8066} } @article{MTMT:3181824, title = {Modelling and Characterization of the Sorption of Kynurenic Acid on Protein Surfaces}, url = {https://m2.mtmt.hu/api/publication/3181824}, author = {Juhász, Ádám and Csapó, Edit and Vécsei, László and Dékány, Imre}, doi = {10.3311/PPch.10185}, journal-iso = {PERIOD POLYTECH CHEM ENG}, journal = {PERIODICA POLYTECHNICA-CHEMICAL ENGINEERING}, volume = {61}, unique-id = {3181824}, issn = {0324-5853}, keywords = {PROTEINS; KINETICS; ENTROPY; ENTHALPY; RATE CONSTANTS; concentration dependence; Serum Albumin; surface plasmon resonance; kynurenic acid; EQUILIBRIUM CONSTANTS; binding kinetics; specific heat; Body fluids; binding energy; Gibbs free energy; free energy; Bins; Surface plasmon resonance spectroscopy; Heat capacity; Plasmons; Physiological condition; Thermodynamic aspects; Pseudo-first order kinetic model; Nonlinear Parameter Estimation; Van’t Hoff relation; Serum albumins}, year = {2017}, eissn = {1587-3765}, pages = {3-9}, orcid-numbers = {Juhász, Ádám/0000-0003-0033-7968; Csapó, Edit/0000-0002-6980-9524; Vécsei, László/0000-0001-8037-3672; Dékány, Imre/0000-0001-5472-5355} }
