Spectroelectrochemistry of Flavonolignans and their DNA-binding Copper Complexes
Sokolová, Romana ; Kubala, M. ; Vavříková, E. ; Ulrichová, J. ; Křen, Vladimír ; Vacek, J.
The oxidation of flavonolagnan silybin and its selected derivatives was studied on glassy carbon electrode in aqueous environment by means of cyclic voltammetry, in situ UV/VIS spectroelectrochemistry and absorption spectrometry. The oxidation mechanism of flavonolignans and their complexion with copper was investigated under anaerobic conditions. The acquired results were interpreted in context of protective (antioxidant) and DNA-binding (prooxidant) properties of flavonolignans and their transition metal complexes.
Multivalentní glykokonjugáty ve studiu interakce lektinových receptorů NK/NKT buněk
Vannucci, Luca ; Pospíšil, Miloslav ; Rossmann, Pavel ; Chernyavskiy, Oleksandr ; Kubínová, Lucie ; Křen, Vladimír ; Luptovcová, Martina ; Svoboda, Jan ; Kuldová, Markéta ; Bezouška, Karel ; Fišerová, Anna
The events following the administration of GN8 in vitro, in vivo and ex vivo, lead to increased expression of CD69. The CD69-dependent IFNg production is modulated by co-activation of NKG2D and Ly49 receptors. Glycodendrimers can assist the dissection of activation network of NK/NKT cell lectin-like receptors in rat and murine models
Multivalentní glykomika v imunoterapii experimentálních nádorů
Vannucci, Luca ; Pospíšil, Miloslav ; Krist, Pavel ; Křen, Vladimír ; Huliková, Katarína ; Luptovcová, Martina ; Svoboda, Jan ; Kuldová, Markéta ; Bezouška, Karel ; Rossmann, Pavel ; Difato, Francesco ; Mosca, F. ; Fišerová, Anna
Lectin-like receptors can modulate the cytotoxic, regulatory and dendritic cell responses by their interactions. GN8 multivalent glycoconjugates are able to internalize inside and activate NKR-P1 positive cells inducing production of IFN-gamma and expression of CD69. The final effect is a modulation of anticancer immunity with reduction of cancer growth
Nitrile hydratase-catalysed transformations of glycosyl cyanides
Mylerová, Veronika ; Šnajdrová, Radka ; Somsák, L. ; Křen, Vladimír ; Martínková, Ludmila
Rhodococcus equi strain A4 is a versatile biocatalyst for hydrolysis of nitriles and amides.
Protein chimistry and massspectromtry in strictural analysis of large proteins
Bezouška, Karel ; Man, Petr ; Pompach, Petr ; Novák, P. ; Havlíček, Vladimír ; Hilgenfeld, R. ; Plíhal, Ondřej ; Sklenář, Jan ; Pišvejcová, Andrea ; Křen, Vladimír
According to the textbook knowledge the use of automated Edman degradation and protein mass spectrometry for the determination of complete primary stricture is limited to small proteins with molecular size less than 10 kDa.
