“…Inhibiting α-glucosidase can not only delay the hydrolysis of carbohydrates into saccharides which were absorbed into blood, thereby controlling postprandial blood glucose, but also protect the islet β cell function and alleviate T2DM and associated complications ( Luis Ros, Francini and Schinella, 2015 ; Sun and Miao, 2020 ). Acarbose, an α-glucosidase inhibitor, has been used as the first-line medicine for the treatment of T2DM, especially for patients who consumed a high-carbohydrate diet, however, the side effects on gastrointestinal digestion restricted its long-term use ( Suttithumsatid et al, 2022 ). Thus, searching for safer inhibitors suitable for long-term use is urgent.…”
