Design and Synthesis of Exocyclic Cyclitol Aziridines as Potential Mechanism‐Based Glycosidase Inactivators

چکیده

Cyclophellitol aziridines have found wide application as mechanism-based, covalent, and irreversible inhibitors of retaining glycosidases. These compounds, like their parent compound, cyclophellitol (a natural product β-glucosidase inactivator), make use the mechanism action glycosidases, which process substrate through formation a transient covalent intermediate. In contrast, inverting other main family glycosyl hydrolases, do not employ such intermediate, and, consequence, useful scaffolds for mechanism-based inhibitor design yet to be discovered. this work, we explore chemistries that allow construction cyclitol with aziridine electrophile attached in an exocyclic fashion, more distal from anomeric carbon – thus putatively closer glycosidase active site nucleophile. The developed allowed synthesis focused library differently N-substituted, α-and β-glucopyranose configured future evaluation or inactivators β-glucosidases alike.

Towards broad spectrum activity-based glycosidase probes: synthesis and evaluation of deoxygenated cyclophellitol aziridines.

Activity-based protein profiling has emerged as a powerful tool for visualizing glycosidases in complex biological samples. Several configurational cyclophellitol isomers have been shown to display high selectivity as probes for glycosidases processing substrates featuring the same configuration. Here, a set of deoxygenated cyclophellitols are presented which enable inter-class profiling of β-g...
