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.
Duvoglustat is an optically active form of 2-(hydroxymethyl)piperidine-3,4,5-triol having 2R,3R,4R,5S-configuration. It has a role as an EC 220.127.116.11 (alpha-glucosidase) inhibitor, an anti-HIV agent, an anti-obesity agent, a bacterial metabolite, a hypoglycemic agent, a hepatoprotective agent and a plant metabolite.
1-Deoxynojirimycin is a potent α-glucosidase inhibitor, suppresses postprandial blood glucose, thereby possibly preventing diabetes mellitus. 1-Deoxynojirimycin as a therapeutic agent by controlling the overgrowth and biofilm formation of S. mutans, it also can block human immunodeficiency virus envelope glycoprotein- mediated membrane fusion at the CXCR4 binding step.
