Acarviosin is a sugar composed of cyclohexitol linked to a 4-amino-4,6-dideoxy-D-glucopyranose. 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] The nitrogen atom binds to α-amylase more tightly than the natural substrate making it more potent than other inhibitors. Several other acarviosin-containing α-amylase inhibitors have been found in microbes including isovalertatins [2] and butytatins [3] from Streptomyces luteogriseus and longer oligosaccharides from Streptomyces coelicoflavus.[4]
