Product Description
Alkaloid. Inhibitor of α-glucosidase, amyloglucosidase and glucosidase I. Does not inhibit glucosidase II, and is reported to be the first glucosidase inhibitor which differentiates glucosidase I from glucosidase II. Does not inhibit α-galactosidase, β-galactosidase, β-glucosidase, α-mannosidase and β-mannosidase.

Product Description
Selective glycosidase inhibitor sharing such activity with other hydroxylated nitrogen containing bicyclic compounds like swainsonine (Prod. No.
ALX-350-077
), castanospermine (Prod. No.
ALX-270-160
), monocyclic deoxynojirimycin (Prod. No.
ALX-580-003
) or fagomine. Most abundant form is calystegine B2 occurring in almost all plants displaying calystegines. Inhibitory potency of calystegine B2 is comparable to other alkaloidal glycosidase inhibitors showing K
i
values below 1µM.
