Chemical Formula: C₁₈H₃₄N₂O₁₄

Mode of Action
Alpha-Glucosidase Inhibition: Blocks enzymes responsible for breaking down complex carbohydrates into glucose.
Delayed Carbohydrate Absorption: Slows the rise in blood glucose levels postprandially.
Reduced Hyperglycemia: Helps in maintaining overall glycemic control.
Uses
Type 2 Diabetes Mellitus: Manages postprandial blood glucose levels.
Metabolic Syndrome: Assists in improving insulin sensitivity and glycemic control.
