Evangelia D. Chrysina,Éva Bokor,K.-M. Alexacou,Maria Despoina Charavgi,George N. Oikonomakos,Spyros E. Zographos,Demetres D. Leonidas,Nikos G. Oikonomakos,László Somsák +8 more
TL;DR: In this paper, the same azide and substituted acetylenes gave 1-(β-d -glucopyranosyl)-4-substituted-1,2,3-triazoles in Cu(I)-catalyzed azide-alkyne cycloadditions.
Journal ArticleDOI
Synthesis of variously coupled conjugates of D-glucose, 1,3,4-oxadiazole, and 1,2,3-triazole for inhibition of glycogen phosphorylase
Sándor Kun,Gergő Zoltán Nagy,Marietta Tóth,Laura Czecze,Albert Nguyen Van Nhien,Tibor Docsa,Pál Gergely,Maria Despoina Charavgi,Paraskevi V. Skourti,Evangelia D. Chrysina,Tamás Patonay,László Somsák +11 more
TL;DR: 5-Phenyltetrazole was transformed into 5-ethynyl- as well as 5-chloromethyl-2-(O-perbenzoylated-β-D-glucopyranosyl)-1,3,4-oxadiazoles by acylation with propiolic acid-DCC or chloroacetyl chloride by the Zemplén protocol.
Journal ArticleDOI
The structure of a novel glucuronoyl esterase from Myceliophthora thermophila gives new insights into its role as a potential biocatalyst.
Maria Despoina Charavgi,Maria Dimarogona,Evangelos Topakas,Paul Christakopoulos,Evangelia D. Chrysina +4 more
TL;DR: These are the first crystal structures of a thermophilic GE both in an unliganded form and bound to a substrate analogue, thus unravelling the organization of the catalytic triad residues and their neighbours lining the active site.
Journal ArticleDOI
The binding of β-D-glucopyranosyl-thiosemicarbazone derivatives to glycogen phosphorylase: A new class of inhibitors
Kyra-Melinda Alexacou,Alia-Cristina Tenchiu,Evangelia D. Chrysina,Maria Despoina Charavgi,Ioannis D. Kostas,Spyros E. Zographos,Nikos G. Oikonomakos,Demetres D. Leonidas +7 more
TL;DR: A group of 15 aromatic aldehyde 4-(β-d-glucopyranosyl)thiosemicarbazones have been synthesized and evaluated as inhibitors of rabbit muscle glycogen phosphorylase b by kinetic studies, revealing that the inhibitors are accommodated at the catalytic site with the glucopyranusyl moiety at approximately the same position as α- d-glue and stabilize the T conformation of the 280s loop.
Journal ArticleDOI
Glucuronoyl Esterase Screening and Characterization Assays Utilizing Commercially Available Benzyl Glucuronic Acid Ester
TL;DR: The three-level experimental procedure not merely facilitates routine, fast and simple biochemical characterizations but it can also give rise to the discovery of different GEs through an extensive screening of heterologous Genomic and Metagenomic expression libraries.
