Synthesis and Characterization of Sugar Derivatives as Functional Gelators
… 4,6-protecting groups on glucose and glucosamine derivatives is to discern the relative structure activity relationships of these systems, and as well to fabricate functional systems which respond to external stimulus. Stimuli responsive or trigger release gel systems formed by sugar based low …

Syntheses related to the preparation of substituted glycosyl derivates of pyrrolo (3,2-f) quinolines : spectroscopic studies of acetylated glycosylamine derivatives
… synthesis of 25 acetylated glycopyranosylamine derivatives (15 of which are newly reported here) from substituted sugar derivatives and amines is described. Eleven different methods were employed in these syntheses. Of the compounds prepared, 15 are substituted glycosylindoline derivatives. The …

Nucleophilic displacement reactions of some carbohydrates in dimethyl sulphoxide
Several 5-0-toluene-p-sulphonyl and 5-iodo derivatives of «-and 3-ribofuranoses and «-xylofuranose have been prepared in order to study their reactions with sodium hydrogen carbonate in dimethyl sulphoxide. Similar reactions are known to convert acylic primary sulphonates and iodides to aldehydes …

Reductive Alkylation of Proteins Towards Structural and Biological Applications
… body. In the last chapter, we present the use of sugar derivatives as a possible less toxic alternative for synthetic glycoproteins. The synthesis of a protein modifier is described and preliminary data of its application as a glycomimetic and cross-linking agent is presented.

Dynamic supramolecular hydrogels with adaptive biological functionality
… Aromatic peptide amphiphiles and aromatic sugar amphiphiles are particularly interesting building blocks in this context and were mainly utilised in this work. For the development of applications and novel uses for peptide nanostructures, robust routes for their surface functionalization, …
