‘Click’ assembly of glycoclusters and discovery of a trehalose analogue that retards Aβ40 aggregation and inhibits Aβ40-induced neurotoxicity
چکیده انگلیسی

Osmolytes have been proposed as treatments for neurodegenerative proteinopathies including Alzheimer’s disease. However, for osmolytes to reach the clinic their efficacy must be improved. In this work, copper(I)-catalyzed azide–alkyne cycloaddition chemistry was used to synthesize glycoclusters bearing six copies of trehalose, lactose, galactose or glucose, with the aim of improving the potency of these osmolytes via multivalency. A trehalose glycocluster was found to be superior to monomeric trehalose in its ability to retard the formation of amyloid-beta peptide 40 (Aβ40) fibrils and protect neurons from Aβ40-induced cell death.
