Miglitol is an oral alpha-glucosidase inhibitor used in the treatment of type 2 diabetes. It works by reversibly inhibiting alpha-glucosidase enzymes in the small intestine, which delays the digestion of complex carbohydrates and subsequently reduces postprandial glucose levels. Approved for clinical use since 1998, miglitol has demonstrated efficacy in improving glycemic control, reducing HbA1c levels, and decreasing both fasting and postprandial plasma glucose concentrations in long-term clinical trials. Additionally, recent studies have suggested that miglitol may have potential as an anti-

Miglustat, sold under the brand name Zavesca among others, is a medication used to treat type I Gaucher disease and Pompe disease.

Swainsonine is an indolizidine alkaloid. It is a potent inhibitor of Golgi alpha-mannosidase II, an immunomodulator, and a potential chemotherapy drug. As a toxin in locoweed (likely its primary toxin) it also is a significant cause of economic losses in livestock industries, particularly in North America. It was first isolated from Swainsona canescens.

Castanospermine is an indolizidine alkaloid first isolated from the seeds of Castanospermum australe. It is a potent inhibitor of some glucosidase enzymes and has antiviral activity in vitro and in mouse models.

Migalastat, sold under the brand name Galafold, is a medication used for the treatment of Fabry disease, a rare genetic disorder. Migalastat is an alpha-galactosidase A (alpha-Gal A) pharmacological chaperone. It was developed by Amicus Therapeutics.

1-Deoxynojirimycin (DNJ or 1-DNJ), also called duvoglustat or moranolin, is an alpha-glucosidase inhibitor, most commonly found in mulberry leaves. Although it can be obtained in small quantities by brewing an herbal tea from mulberry leaves, interest in commercial production has led to research on developing mulberry tea higher in DNJ, and on alternate routes of production, such as via Bacillus species.
