(Z)-Butylidenephthalide, a natural product isolated and purified from the roots of Angelica sinensis, has antitumor effect, can effectively inhibit the tumor growth in the glioma.

D-Fagomine is an iminosugar originally isolated from seeds of buckwheat (Fagopyrum sculentum Moench), present in the human diet and now available as a pure crystalline product.

Kaempferol 7-O-rhamnoside is a natural product isolated and purified from the herbs of Maytenus hookeri.

Castanospermine inhibits all forms of α- and β-glucosidases, especially glucosidase l (required for glucoprotein processing by transfer of mannose and glucose from asparagine-linked lipids).

Methyl caffeate is an α-glucosidase inhibitor found in species of Solanum and Magnolia. It exhibits several biological activities, including suppressing growth of Pseudomonas, Klebsiella, and Mycobacterium, inhibiting replication of HIV, and decreasing blood glucose levels in models of diabetes.

ML266 is a glucocerebrosidase activator and a non-inhibitory chaperone of glucocerebrosidase.

Butyl isobutyl phthalate is isolated from the rhizoid of Laminaria japonica. Butyl isobutyl phthalate is a non-competitive α-glucosidase inhibitor with an IC50 value of 38 μM. Butyl isobutyl phthalate shows a hypoglycemic effect and has the potential for diabetes treatment.

Deoxynojirimycin HCl, a natural product isolated and purified from the root barks of Morus alba L., shows inhibitory activity against α-glucosidases, inhibitors of α-glucosidase are promising candidates for the development of antitype II diabetics and anti-AIDS drugs.

N-Nonyldeoxynojirimycin is a glucosidase inhibitor with IC50s of 0.42 and 8.4 μM for acid α-glucosidase and α-1,6-glucosidase respectively.

2'-Methoxykurarinone, a natural product isolated and purified from the roots of Sophora flavescens Ait.

Oroxin A is the major component of an ethanol-water Oroxylum indicum (L.) Kurz (Bignoniaceae) seed extract (OISE), activates peroxisome proliferator-activated receptor γ (PPARγ) by docking into the PPARγ protein ligand-binding domain. Oroxin A exhibits an inhibitory activity against α-glucosidase and an antioxidant capacity. Oroxin A exerts anti-breast cancer effects by inducing ER stress-mediated senescence.

N-Methylmoranoline is an inhibitor of α-glucosidase inhibitor.

Valiolamine, an aminocyclitol has been isolated from the fermentation broth of Streptomyces hygroscopicus subsp. Valiolamine has potent alpha-glucosidase inhibitory activity against porcine intestinal sucrase, maltase and isomaltase.
