Abstract:Prediabetes is defined as blood glucose levels above normal but below diabetes thresholds, and up to 70% of individuals with prediabetes will eventually develop diabetes if left untreated. Acarbose, the first FDA approved anti-prediabetes agent, has some disadvantages, such as reducing the risk of diabetes by only 36%, side effects and limited effects on complications. The aim of this study is to develop a new agent to treat prediabetes and to investigate the anti-prediabetes effects and mechanisms of acarbose and an Oroxylum indicum seed extract (OISE) in prediabetic mice. The combined drugs can reduce the dose of acarbose by 80% and reduce the risk of diabetes by 75%, which is one fold higher than acarbose monotherapy. The combined drugs showed synergistic anti-prediabetes effects and could be effective in preventing the complications of prediabetes. The combined drugs could improve glucose tolerance, improve lipid metabolism and reduce oxidative stress and tissue damage. For the mechanisms, the combined drugs can reduce synergistically postprandial hyperglycaemia by inhibiting a-glucosidase. Furthermore, baicalein in OISE was demonstrated to be a major component in reducing oxidative stress and chrysin was the primary compound that activated PPAR gamma. (C) 2016 Elsevier Masson SAS.
