Although the removal of the 5,6‐O‐isopropylidene protecting group is typically rapid and quantitative under acidic conditions, an unexpected inhibition of this reaction is observed for the two C3‐epimers, 3‐O‐imidazole sulfonyl moiety. X‐ray data show a two‐faced imidazole ring orientation in the crystal, while solution state NOE data reveal a critical interaction type between the isopropylidene and the imidazole rings. Advanced conformational searches coupled with ab initio molecular modeling illuminate and explain the NMR and kinetic data, and lay the groundwork for the most plausible mechanism of this unprecedented inhibition. These results provide valuable insights into the cross‐coupling of carbohydrate O‐protecting groups and shed light on how specific ring orientations and steric effects can trigger the inhibition of an otherwise easily feasible reaction, such as an acid‐catalyzed hydrolysis.}, year = {2025}, eissn = {1521-3765}, orcid-numbers = {Szaniszló, Szebasztián/0000-0002-8929-0635; Farkas, Viktor/0000-0002-8815-2783; Sulyok-Eiler, Máté/0000-0002-3968-8776; Láng, András/0000-0002-1209-3350; Harmat, Veronika/0000-0002-1866-9904; Perczel, András/0000-0003-1252-6416} } @article{MTMT:36071903, title = {Rovibrational overtone and combination bands of the HCNH+ ion}, url = {https://m2.mtmt.hu/api/publication/36071903}, author = {Kassayová, Miroslava and Jiménez-Redondo, Miguel and Sarka, János and Dohnal, Petr and Glosík, Juraj and Caselli, Paola and Jusko, Pavol}, doi = {10.1016/j.saa.2025.126040}, journal-iso = {SPECTROCHIM ACTA A}, journal = {SPECTROCHIMICA ACTA PART A-MOLECULAR AND BIOMOLECULAR SPECTROSCOPY}, volume = {337}, unique-id = {36071903}, issn = {1386-1425}, year = {2025}, eissn = {1873-3557}, orcid-numbers = {Jiménez-Redondo, Miguel/0000-0001-9221-8426; Sarka, János/0000-0003-4269-0727; Dohnal, Petr/0000-0003-0341-0382} } @article{MTMT:34160976, title = {ANALYSIS OF THE IRON STATES IN IRON-CONTAINING PHARMACEUTICAL PRODUCTS USING MÖSSBAUER SPECTROSCOPY}, url = {https://m2.mtmt.hu/api/publication/34160976}, author = {Alenkina, Irina V. and Chukin, Andrey V. and Leitus, Gregory and Denisova, Olga V. and Gracheva, Maria and Felner, Israel and Kuzmann, Ernő and Homonnay, Zoltán and Oshtrakh, Michael I.}, doi = {10.1016/j.jpba.2023.115745}, journal-iso = {J PHARMACEUT BIOMED ANAL}, journal = {JOURNAL OF PHARMACEUTICAL AND BIOMEDICAL ANALYSIS}, volume = {237}, unique-id = {34160976}, issn = {0731-7085}, year = {2024}, eissn = {1873-264X}, orcid-numbers = {Gracheva, Maria/0000-0001-5245-8425; Kuzmann, Ernő/0000-0002-0183-6649; Homonnay, Zoltán/0000-0001-5299-5394; Oshtrakh, Michael I./0000-0002-2937-5194} } @article{MTMT:34890367, title = {QED corrections to the correlated relativistic energy: One-photon processes}, url = {https://m2.mtmt.hu/api/publication/34890367}, author = {Margócsy, Ádám and Mátyus, Edit}, doi = {10.1063/5.0193250}, journal-iso = {J CHEM PHYS}, journal = {JOURNAL OF CHEMICAL PHYSICS}, volume = {160}, unique-id = {34890367}, issn = {0021-9606}, abstract = {This work is a collection of initial calculations and formal considerations within the Salpeter–Sucher exact equal-time relativistic quantum electrodynamics framework. The calculations are carried out as preparation for the computation of pair, retardation, and radiative corrections to the relativistic energy of correlated two-spin-1/2-fermion systems. In this work, particular attention is paid to the retardation and the “one-loop” self-energy corrections, which are known to be among the largest corrections to the correlated relativistic energy. The theoretical development is supplemented with identifying formal connections to the non-relativistic quantum electrodynamics framework, which is based on a correlated but non-relativistic reference, as well as to the “1/Z approach,” which is built on a relativistic but independent-particle zeroth order. The two complementary directions currently provide the theoretical framework for light atomic–molecular precision spectroscopy and heavy-atom phenomena.

Earlier applications of drachmannized relativistic corrections for molecular systems were hindered due to the unknown analytic matrix elements of 1/rix1/rjy-type operators with fECGs. In the present work, one of the 1/r factors is approximated by a linear combination of Gaussians, which results in calculable integrals. The numerical approach is found to be precise and robust over a range of molecular systems and nuclear configurations, and thus, it opens the route toward an automated evaluation of high-precision relativistic corrections over potential energy surfaces of polyatomic systems. Furthermore, the newly developed integration approach makes it possible to construct the matrix representation of the square of the electronic Hamiltonian relevant for energy lower-bound as well as time-dependent computations of molecular systems with a flexible and high-precision fECG basis representation.}, year = {2024}, eissn = {1089-7690}, orcid-numbers = {Rácsai, Balázs/0009-0003-6780-9138; Ferenc, Dávid/0000-0002-5193-540X; Margócsy, Ádám/0000-0003-1815-0405; Mátyus, Edit/0000-0001-7298-1707} } @article{MTMT:35893349, title = {Affinity-based categorization of antimicrobial and cell-penetrating peptides in vesicle interactions}, url = {https://m2.mtmt.hu/api/publication/35893349}, author = {Tamas, Beke-Somfai and Tasvilla, Sonallya and Szigyártó, Imola Csilla and Tunde, Juhasz and Kinga, Ilyes and Priyanka, Singh and Delaram, Khamari and Edit, Buzas and Zoltan, Varga}, journal-iso = {J EXTRACELLULAR VESICL}, journal = {JOURNAL OF EXTRACELLULAR VESICLES}, volume = {13}, unique-id = {35893349}, year = {2024}, eissn = {2001-3078}, pages = {287-287} } @CONFERENCE{MTMT:32958399, title = {Leaf senescence initiation related alterations in the iron homeostasis of the chloroplasts.
