β-glucosidase 2

Australine is a pyrrolizidine alkaloid originally isolated fromC. australethat has enzyme inhibitory activities.1,2,3It is an inhibitor of glucoamylase (IC50= 5.8 μM) that also inhibits glucosidase I, sucrase, maltase, andA. nigerα-glucosidase (IC50s = 20, 28, 35, and 28 μM, respectively).2,3Australine is selective for these enzymes over glucosidase II, α- and β-mannosidase, and α- and β-galactosidase up to 500 μM, β-glucosidase, with only 5% inhibition at 66 μM, as well as isomaltase and trehalase (IC50= 97 and 160 μM, respectively). Australine (500 μg/ml) inhibits glycoprotein processing of viral glycoproteins in influenza virus-infected MDCK cells and induces the accumulation of glycoproteins.2 1.Molyneux, R.J., Benson, M., Wong, R.Y., et al.Australine, a novel pyrrolizidine alkaloid glucosidase inhibitor from Castanospermum australJ.

Prunetin 5-O-β-D-glucopyranoside, an isoflavone obtained from Potentilla astracanica extracts, is a potent uncompetitive inhibitor of α-glucosidase (IC 50 = 56.05 μg/mL). It serves as a valuable tool for type-2 diabetes research.

2-Nitrophenyl a-D-glucopyranoside is a substrate of β-glucosidase [1].

Endoglycoceramidase II (EGCase II), an endo-β-glucosidase, catalyzes the hydrolysis of the β-glycosidic linkage between oligosaccharides and ceramides in glycosphingolipids, releasing the complete glycan from ceramide [1] [2].

2'-Hydroxygenistein is a naturally occurring flavonoid with a wide range of antioxidant, anti-inflammatory, anticancer, and anti-endometrial hyperplasia potentials.2'-Hydroxygenistein is a inhibitor of a variety of enzymes, including indole-3-acetic acid oxidase, α-glucosidase, β-glucuronidase, and lysozyme.

beta-Amyrone (β-Amyron) has antifungal activity against Chikungunya virus replication with an EC50 of 86 uM. beta-Amyrone has anti-inflammatory activity through inhibiting the expression of COX-2. beta-Amyrone exhibits anti-α-glucosidase inhibitory activity and moderate AChE activity. β-Amyrone can be used in the research of disease like inflammation, infection, and obesity.
