Arylsulfonyl histamine derivatives as powerful and selective ?-glucosidase inhibitors.


ABSTRACT: A series of simple N-arylbenzenesulfonyl histamine derivatives were prepared and screened against ?-glucosidase. Inhibition was in the micromolar range for several N ?,N ?-di-arylsulfonyl compounds, with N ?,N ?-di-4-trifluorobenzenesulfonyl histamine (IId) being the best inhibitor. Compound IId is a reversible and competitive ?-glucosidase inhibitor, and presented good selectivity with respect to other target enzymes, including ?-glucosidase and ?-amylase, and interesting predicted physicochemical properties. Docking studies have been run to postulate ligand-enzyme interactions to account for the experimental results. In vivo, compound IId produced a similar hypoglycemic effect to acarbose with half of its dose.
