In this study, a new series of quinoxalinone derivatives (5a-5p, 6a-6n) was designed and its hypoglycemic activity was evaluated. The results showed that compounds 5i and 6b exhibited stronger hypoglycemic effects than the lead compounds and were comparable to the positive control Pioglitazone. 5i and 6b may exert hypoglycemic effects by alleviating cellular OS and modulating the interactions among GLUT4, SGLT2, and GLUT1 proteins. The alleviating cellular OS of compound 6b was better than that of 5i, and 6b was found to bind better than 5i for most of the screening targets. In summary, compound 6b is a potential lead compound with hypoglycaemic activity.3.

Wheat bran-soluble dietary fibre (WB-SDF) is known for its hypoglycaemic properties and its potential to control postprandial blood glucose levels in individuals with hyperglycaemia. However, the digestive process may alter its glucose-lowering potential. This study investigated the effects of in vitro simulated digestion on the hypoglycaemic efficacy of WB-SDF.

The genus Chrysanthemum has been widely used as both folk medicine and food in East Asia for thousands of years, serving as a significant source of nutritional and pharmacological value. According to the theory of traditional Chinese medicine, it clears heat and toxic materials and regulates liver function. Accumulating evidence has demonstrated that polysaccharides from the genus Chrysanthemum, especially Chrysanthemum morifolium, Chrysanthemum indicum, and Coreopsis tinctoria, are vital representative macromolecules with diverse biological activities, including antioxidant, immunomodulatory, anti-inflammatory, hypoglycemic, antitumor, and antiviral properties as well as the ability to regulate the gut microbiota.

One way to treat diabetes mellitus type II is by using α-glucosidase inhibitor, that will slow down the postprandial glucose intake. Metabolomics analysis of Artabotrys sumatranus leaf extract was used in this research to predict the active compounds as α-glucosidase inhibitors from this extract. Both multivariate statistical analysis and machine learning approaches were used to improve the confidence of the predictions.

Background: Biological sex influences Alzheimer's disease (AD) development, particularly concerning brain insulin resistance (bIR) and early energy metabolism defects. Biliverdin reductase-A (BVR-A) plays a crucial role in insulin signaling, and its downregulation leads to bIR. However, the sex-related differences in AD neuropathology and underlying mechanisms remain unclear.

Background: Brain insulin resistance (bIR) heavily impacts on the core pathological processes of aging and Alzheimer disease (AD) since insulin regulates brain metabolism and cognitive functions. A close link among bIR, oxidative stress (OS) and mitochondrial defects exists, that contributes to brain dysfunctions observed in AD. Intriguingly, several studies suggest that intranasal insulin treatment (INI) enhances cognitive performance and reduced AD neuropathology both in humans and murine models of AD.
