The design of covalent inhibitors in glycoscience research is important for the development of chemical biology probes. Here we report the synthesis of a new carbocyclic mechanism-based covalent inhibitor of an α-glucosidase. The enzyme efficiently catalyzes its alkylation via either an allylic cation or a cationic transition state.

Glycoside hydrolase family 20 (GH20) β-N-acetyl-d-hexosaminidase (Hex) catalyzes the cleavage of glycosidic linkages in glycans, glycolipids and glycoproteins, and is involved in glycoprotein modification, metabolism of glycoconjugate and the degradation of chitin in fungal cell walls and arthropod exoskeletons. GH84 O-β-N-acetyl-d-glucosaminidase (OGA)

Publisher Summary This chapter discusses the results of the studies that permit some generalizations on the catalytic mechanism of glycoside hydrolases from widely differing sources and with different sugar and aglycon specificities and that have become available over the past 15 years.

The treatment of benzyl 2,3-O-isopropylidene-β-L-xylopyranoside with N-hydroxyphthalimide under Mitsunobu conditions, followed by protecting-group interchange, gave benzyl 4-O-[(tert-butoxycarbonyl)amino]-2,3- O-isopropylidene-α-D-arabinoside. Mild acid hydrolysis and catalytic hydrogenolysis afforded 4-O-[(tert-butoxycarbonyl)amino]-D-arabinose that,

There are few reports on soluble epoxide hydrolase (sEH) structure-activity relationship studies using natural product-based scaffolds. In this study, we discovered that C-30 urea derivatives of glycyrrhetinic acid such as 33, rather than C-20/C-3 urea derivatives, possess in vitro sEH inhibitory capabilities.

Discovery of a Novel Microbial Glycoside Hydrolase Directing Formation of New α‐Amylase Inhibitors
Chemistry – A European JournalABSTRACT Glycoside hydrolases (GHs) comprise a large and diverse family of enzymes that catalyze the hydrolysis of glycosidic bonds in a wide range of glycan substrates, including polysaccharides, oligosaccharides, and glycoconjugates.

The hypoglycemic effect of a glycoside hydrolase inhibitor (BAY g 5421) was tested in 10 non-insulin dependent, overweight diabetics by means of continuous in vivo glucograms. There was a highly significant reduction of serum glucose with a dosage of 3 x 100 mg glycoside hydrolase inhibitor, after dosage division to 6 x 50 mg there was an additional ...
