-cyclosulfamidate mannose-configured cyclitol allows isoform-dependent inhibition of GH47 α-d-mannosidases through a bump-hole strategy.

Class I inverting exo-acting α-1,2-mannosidases (CAZY family GH47) display an unusual catalytic itinerary featuring ring-flipped mannosides, → → . Conformationally locked compounds, such as kifunensine, display nanomolar inhibition but large multigene GH47 mannosidase families render specific "isoform-dependent" inhibition impossible. Here we develop a bump-and-hole strategy in which a new mannose-configured 1,6--cyclic sulfamidate inhibits α-d-mannosidases by virtue of its conformation.

Past, present, and future developments in enantioselective analysis using capillary electromigration techniques.

Enantioseparation of chiral products has become increasingly important in a large diversity of academic and industrial applications. The separation of chiral compounds is inherently challenging and thus requires a suitable analytical technique that can achieve high resolution and sensitivity. In this context, CE has shown remarkable results so far.

Structure-Activity Relationship Studies of α-Ketoamides as Inhibitors of the Phospholipase A and Acyltransferase Enzyme Family.

The phospholipase A and acyltransferase (PLAAT) family of cysteine hydrolases consists of five members, which are involved in the Ca-independent production of -acylphosphatidylethanolamines (NAPEs). NAPEs are lipid precursors for bioactive -acylethanolamines (NAEs) that are involved in various physiological processes such as food intake, pain, inflammation, stress, and anxiety. Recently, we identified α-ketoamides as the first pan-active PLAAT inhibitor scaffold that reduced arachidonic acid levels in PLAAT3-overexpressing U2OS cells and in HepG2 cells.
