Ultrahigh-Resolution Homo- and Heterodecoupled 1H and TOCSY NMR Experiments.
Timári I, Bagi P, Keglevich G, E Kövér K. Timári I, et al. ACS Omega. 2022 Nov 15;7(47):43283-43289. doi: 10.1021/acsomega.2c06102. eCollection 2022 Nov 29. ACS Omega. 2022. PMID: 36467931 Free PMC article.
The original homonuclear decoupled (pure shift) experiments provide ultrahigh-resolution (1)H spectra of compounds containing NMR-active heteronuclei of low natural isotopic abundance (e.g., (13)C or (15)N). In contrast, molecules containing highly abundant heteronuclei (l …

Conformational Analysis of Heparin-Analogue Pentasaccharides by Nuclear Magnetic Resonance Spectroscopy and Molecular Dynamics Simulations.
Balogh G, Gyöngyösi T, Timári I, Herczeg M, Borbás A, Sadiq SK, Fehér K, Kövér KE. Balogh G, et al. J Chem Inf Model. 2021 Jun 28;61(6):2926-2936. doi: 10.1021/acs.jcim.1c00200. Epub 2021 May 24. J Chem Inf Model. 2021. PMID: 34029080
We found that the conformation of the G ring is dominated by the (2)S(O) skewed boat next to the (1)C(4) chair in all three derivatives. ...Both G and E ring flips are also accompanied by changes along the interglycosidic linkages, which take place highly synchronou …

Photochemical and Structural Studies on Cyclic Peptide Models.
Nagy TM, Knapp K, Illyés E, Timári I, Schlosser G, Csík G, Borics A, Majer Z, Kövér KE. Nagy TM, et al. Molecules. 2018 Aug 30;23(9):2196. doi: 10.3390/molecules23092196. Molecules. 2018. PMID: 30200264 Free PMC article.
Liquid cromatography-mass spectrometry (LC-MS) measurements indicated the presence of multiple photooxidation products (e.g., dimers, multimers and other oxidated products), suggesting that besides the photolysis of disulfide bonds secondary photolytic processes take place …

The Effect of Mesenchymal Stem Cell-Derived Microvesicles on Erythroid Differentiation of Umbilical Cord Blood-Derived CD34+ Cells.
Pashoutan Sarvar D, Karimi MH, Movassaghpour A, Akbarzadehlaleh P, Aqmasheh S, Timari H, Shamsasenjan K. Pashoutan Sarvar D, et al. Adv Pharm Bull. 2018 Jun;8(2):291-296. doi: 10.15171/apb.2018.034. Epub 2018 Jun 19. Adv Pharm Bull. 2018. PMID: 30023331 Free PMC article.
Methods: In this descriptive study, CD34(+) cells were cultured with mixture of SCF (10 ng/ml) and rhEPO (5 U/ml) cytokines in complete IMDM medium as positive control group. Then, in MV1- and MV2-groups, microvesicles at 10 and 20 g/ml concentration were added. After 72 h …
