alpha-d-glucosidase

α-Glucosidase (α-D-Glucosidase) is a carbohydrate hydrolyzing enzyme that catalyzes the release of α-glucose from the non-reducing end of the substrate, playing a vital role in glucose absorption by the small intestine. Inhibiting α-Glucosidase effectively manages non-insulin-dependent diabetes mellitus (NIDDM).

Torachrysone-8-O-b-D-glucoside exhibits alpha-glucosidase inhibitory activities and may be utilized for managing type 2 diabetes.

Isorhamnetin-3-O-glucoside (Isorhamnetin-3-O-beta-D-Glucoside) inhibits the activity of alpha-glucosidase from rat intestine; it exhibits a potent rat lens aldose reductase (RLAR) inhibition in vitro, its IC(50) being 1.4 microM and has inhibitory effects of sorbitol accumulation, suggests that it is a leading compound for further study as a new drug for the prevention and/or treatment of diabetes and its complications.

alpha-Spinasterol glucoside (α-Spinasterol-3-O-β-D-glucoside) is a natural sterol glucoside exhibiting weak inhibitory activity against alpha-glucosidase (IC₅₀ = 75.9 µM).
