Journal ArticleDOI
Synthetic derivatives of genistein, their properties and possible applications.
Aleksandra Rusin,Zdzisław Krawczyk,Grzegorz Grynkiewicz,Agnieszka Gogler,Jadwiga Zawisza-Puchałka,Wiesław Szeja +5 more
TL;DR: In this paper, the authors summarize current knowledge about the properties of synthetic genistein derivatives and discuss possible clinical application of selected novel compounds, relevant to the synthesis of its derivatives.
Journal ArticleDOI
Isoflavones, their Glycosides and Glycoconjugates. Synthesis and Biological Activity.
TL;DR: A new body of evidence has emerged, indicating that sugar moiety can play a much more significant role, when attached to a pharmacophore, then being a mere “solubilizer”.
Journal ArticleDOI
Dielectric studies on mobility of the glycosidic linkage in seven disaccharides.
Kamil Kaminski,Ewa Kamińska,Patryk Wlodarczyk,Sebastian Pawlus,D. Kimla,Anna Kasprzycka,Marian Paluch,J. Ziolo,Wiesław Szeja,K. L. Ngai +9 more
TL;DR: The activation energies and dielectric strengths for the beta-relaxation determined herein provide valuable information about the flexibility of the glycosidic bond and the mobility of this particular linkage in the disaccharides studied, essential for the control of the diffusivity of drugs or water entrapped in the sugar matrix.
Journal ArticleDOI
Identifying the origins of two secondary relaxations in polysaccharides.
Kamil Kaminski,Ewa Kamińska,K. L. Ngai,Marian Paluch,Patryk Wlodarczyk,Anna Kasprzycka,Wiesław Szeja +6 more
TL;DR: The slower secondary relaxation of the polysaccharides is identified as the Johari-Goldstein beta-relaxation, which is supposedly a universal and fundamental process in all glass-forming substances.
