To investigate the antidiabetic effects and mechanisms of quinoa on type 2 diabetes mellitus (T2DM) mice model. In this context, we induced the T2DM mice model with a high-fat diet (HFD) combined with streptozotocin (STZ), followed by treatment with a quinoa diet. To explore the impact of quinoa on the intestinal flora, we predicted and validated its potential mechanism of hypoglycemic effect through network pharmacology, molecular docking, western blot, and immunohistochemistry (IHC). We found that quinoa could significantly improve abnormal glucolipid metabolism in T2DM mice. Further analysis showed that quinoa contributed to the improvement of gut microbiota composition positively. Moreover, it could downregulate the expression of TAS1R3 and TRPM5 in the colon. A total of 72 active components were identified by network pharmacology. Among them, TAS1R3 and TRPM5 were successfully docked with the core components of quinoa. These findings confirm that quinoa may exert hypoglycemic effects through gut microbiota and the TAS1R3/TRPM5 taste signaling pathway.

Introduction: Type 2 diabetes mellitus (T2DM) often leads to elevated blood glucose levels and lipid metabolism disorder, which is generally accompanied by dysbiosis of gut microbiota and metabolic dysfunction.
Methods: In this study, a mouse model of T2DM was established by feeding a high-fat/sucrose diet combined with injecting a low dose of streptozotocin. The aim of this study was to analyze the regulatory effect of Suaeda salsa extract (SSE) on T2DM and its effect on the intestinal flora of mice.

Background: Fibroblast Growth Factor 21 (FGF21) is a naturally occurring peptide hormone involved in the regulation of glycolipid metabolism, and it shows promise as a potential treatment for type 2 diabetes mellitus (T2DM). However, the short half-life and poor pharmacokinetics of native FGF21 limit its efficacy in reducing hyperglycemia in vivo. Therefore, maintaining stable and sustained blood concentrations of FGF21 is crucial for its role as an effective regulator of glycolipid metabolism in vivo.

The intracellular viscosity plays a pivotal role as a physicochemical factor and an important indicator of organelles performance. Abnormal changes in subcellular viscosity are often associated with cellular malfunction and various diseases. Nonalcoholic steatohepatitis (NASH) is the most common liver disease related with type 2 diabetes mellitus (T2DM), and both are linked to aberrant mitochondrial viscosity.

Ethnopharmacological Relevance: Type 2 diabetes mellitus (T2DM) is a metabolic disease that can lead to complications affecting multiple organs, including the liver. Gegen Qinlian Decoction (GQD) has demonstrated considerable efficacy in the management of T2DM and its complications in accordance with the tenets of modern Chinese medicine. However, the molecular mechanism by which GQD alleviates diabetic liver injury is unclear.

Corosolic acid (CA), a natural triterpenoid, exhibits various biological activities and is often called as plant-derived insulin due to its significant hypoglycemic effects, making it especially beneficial for individuals with diabetes or high blood glucose levels. However, CA has notable in vitro toxicity, low water solubility, and poor pharmacokinetic properties. To address these limitations, a series of CA derivatives were synthesized, resulting in the identification of derivative H26, which demonstrates a significantly enhanced hypoglycemic effect, reduced toxicity, and improved pharmacokinetic characteristics compared to CA.
