MedKoo CAT#: 326758

CAS#: 53185-12-9

Description: Fagomine, also known as D-Fagomine, is an inhibitor of various Glycosidases, including rat intestinal surcase and bovine α-Fucosidase with IC50 of 90μM and 140 μM, respectively. D-Fagomine attenuates metabolic alterations induced by a high-energy-dense diet in rats. D-fagomine is present in common buckwheat-based foodstuffs in amounts ranging from 1 to 25 mg/kg or mg/L, it is stable during boiling, baking, frying and fermentation, and it is biosynthesised upon sprouting.

Price and Availability




Fagomine is not in stock, but may be available through custom synthesis. For cost-effective reason, minimum 1 gram order is requested. The product will be characterized by NMR, HPLC and MS analysis. Purity (HPLC) is usually >98%. CoA, QC data, MSDS will be provided when product is successfully made. The estimated lead time is 2-3 months. Please send email to sales@medkoo.com to inquire quote.
