Here we extended the study to 33 new seleno-glycoconjugates with the aim to improve potency and selectivity. Three selenoglycosides and three glycosyl selenenylsulfides displayed IC50 against bloodstream Trypanosoma brucei in the sub-μM range (IC50 0.35–0.77 μM) and four of them showed an improved selectivity (selectivity index >38-folds vs. murine and human macrohages). For the glycosyl selenylsulfides, the anti-trypanosomal activity was not significantly influenced by the nature of the moiety attached to the sulfur atom. Except for a quinoline-, and to a minor extent a nitro-derivative, the most selective hits induced a rapid (within 60 min) and marked perturbation of the LMWTredox homeostasis.

It was also pointed out that the TA dispersion conditions and its analytical utilization for proteomics can be easily accomplished in a commercial CE-MS instrument. In the proposed Taylor–Aris dispersion-assisted mass spectrometry (TADA-MS) analysis 0.5 μL sample is injected into a 65 cm long 50 μm i.d. capillary and pumped with 1 bar toward the MS. The procedure is efficient for the direct injection analysis of components having low diffusion coefficients (proteins) that are present in complex matrices of small organic and inorganic compounds. © 2024 The Authors.

These peptides, like other compounds with antimicrobial activity, often have significant superoxide dismutase (SOD) activity. One direction of our research is the characterization of peptides modeling the CuZnSOD enzyme and the determination of their biological activity, and these results may contribute to the development of novel antimicrobial peptides. In the framework of this research, we have synthesized 10, 15, and 16-membered model peptides containing the amino acid sequence corresponding to the Cu(II) and Zn(II) binding sites of the CuZnSOD enzyme, namely the Zn(II)-binding HVGD sequence (80–83. fragments), the Cu(II)-binding sequence HVH (fragments 46–48), and the histidine (His63), which links the two metal ions as an imidazolate bridge: Ac-FHVHEGPHFN-NH2 (L1(10)), Ac-FHVHAGPHFNGGHVG-NH2 (L2(15)), and Ac-FHVHEGPHFNGGHVGD-NH2 (L3(16)). pH-potentiometric, UV-Vis-, and CD-spectroscopy studies of the Cu(II), Zn(II), and Cu(II)-Zn(II) mixed complexes of these peptides were performed, and the SOD activity of the complexes was determined. The binding sites preferred by Cu(II) and Zn(II) were identified by means of CD-spectroscopy. From the results obtained for these systems, it can be concluded that in equimolar solution, the –(NGG)HVGD- sequence of the peptides is the preferred binding site for copper(II) ion. However, in the presence of both metal ions, according to the native enzyme, the -HVGD- sequence offers the main binding site for Zn(II), while the majority of Cu(II) binds to the -FHVH- sequence. Based on the SOD activity assays, complexes of the 15- and 16-membered peptide have a significant SOD activity. Although this activity is smaller than that of the native CuZnSOD enzyme, the complexes showed better performance in the degradation of superoxide anion than other SOD mimics. Thus, the incorporation of specific amino acid sequences mimicking the CuZnSOD enzyme increases the efficiency of model systems in the catalytic decomposition of superoxide anion.}, keywords = {Multihistidine peptides; Zn(II)-complexes; Cu(II)-complex}, year = {2024}, eissn = {1420-3049}, orcid-numbers = {Székely, Enikő/0009-0008-7447-4723; Lihi, Norbert/0000-0003-2986-2395; Várnagy, Katalin/0000-0003-0846-4689} } @article{MTMT:34538335, title = {Nanoscale structural characteristics and in vitro bioactivity of borosilicate – polyvinyl alcohol (PVA) hybrid aerogels for bone regeneration}, url = {https://m2.mtmt.hu/api/publication/34538335}, author = {Balogh, Zoltán and Len, Adél and Baksa, Viktória and Krajnc, Andraž and Herman, Petra and Szemán-Nagy, Gábor and Czigány, Zsolt and Fábián, István and Kalmár, József and Dudás, Zoltán Imre}, doi = {10.1021/acsanm.3c05668}, journal-iso = {ACS APPL NANO MATER}, journal = {ACS APPLIED NANO MATERIALS}, volume = {7}, unique-id = {34538335}, keywords = {Bone regeneration}, year = {2024}, eissn = {2574-0970}, pages = {4092-4102}, orcid-numbers = {Szemán-Nagy, Gábor/0000-0003-1906-0188; Czigány, Zsolt/0000-0001-6410-8801; Kalmár, József/0000-0002-2422-6106} }
