Acarbose is an oligosaccharide, whereas miglitol resembles a monosaccharide. Miglitol is fairly well absorbed by the body, as opposed to acarbose. Moreover, acarbose inhibits pancreatic alpha-amylase in addition to alpha-glucosidase, and is degraded by gut bacterial maltogenic alpha-amylase and cyclomaltodextrinase. [4] [5]
Acarbose degradation is the unique feature of glycoside hydrolases in gut microbiota, acarbose degrading glucosidase, which hydrolyze acarbose into an acarviosine-glucose and glucose. [17] Human enzymes do transform acarbose: the pancreatic alpha-amylase is able to perform a rearrangement reaction , moving the glucose unit in the "tail" maltose ...
Miglitol is an oral alpha-glucosidase inhibitor used in the treatment of type 2 diabetes. It works by reversibly inhibiting alpha-glucosidase enzymes in the small intestine, which delays the digestion of complex carbohydrates and subsequently reduces postprandial glucose levels. [ 1 ]
Hence, α-glucosidase inhibitors (like acarbose) are used as anti-diabetic drugs in combination with other anti-diabetic drugs. Luteolin has been found to be a strong inhibitor of α-glucosidase. The compound can inhibit the enzyme up to 36% with a concentration of 0.5 mg/ml. [ 21 ] As of 2016, this substance is being tested in rats, mice and ...
miglitol; acarbose; voglibose; These medications are rarely used in the United States because of the severity of their side-effects (flatulence and bloating). They are more commonly prescribed in Europe. They do have the potential to cause weight loss by lowering the amount of sugar metabolized.
Acarbose is a pseudotetrasaccharide mimicking maltotetraose (a substructure of starch). One of the glucose units has been replaced by valienamine - a carbasugar, linked to the next carbohydrate by an amine bridge. Another of the glucose units appears as a 6-deoxy variant. Acarbose is an enzyme inhibitor that is used as a drug against type 2 ...
Alpha glucosidase inhibitors delay glucose absorption at the intestine level and thereby prevent sudden surge of glucose after a meal. [2] There are three major drugs which belong to this class, acarbose, miglitol and voglibose, [2] of which voglibose is the newest.
Acarviosin is part of the potent α-amylase inhibitor acarbose and its derivatives. Acarviosin is a product of the degradation of acarbose by gut microbiota, the glycoside hydrolase from gut bacteria Lactobacillus plantarum is able to hydrolyze acarbose to maltose and acarviosin. [1]
