Diabetes mellitus (DM) affects about 9.3% of the population globally. Hyperhomocysteinemia (HHcy) has been implicated in the pathogenesis of DM, owing to its promotion of oxidative stress, β-cell dysfunction, and insulin resistance. HHcy can result from low status of one-carbon metabolism (OCM) nutrients (e.g., folate, choline, betaine, vitamin B6, B12), which work together to degrade homocysteine by methylation. The etiology of HHcy may also involve genetic variation encoding key enzymes in OCM. This review aimed to provide an overview of the existing literature assessing the link between OCM nutrients status, related genetic factors, and incident DM. We also discussed possible mechanisms underlying the role of OCM in DM development and provided recommendations for future research and practice. Even though the available evidence remains inconsistent, some studies support the potential beneficial effects of intakes or blood levels of OCM nutrients on DM development. Moreover, certain variants in OCM-related genes may influence metabolic handling of methyl-donors and presumably incidental DM. Future studies are warranted to establish the causal inference between OCM and DM and examine the interaction of OCM nutrients and genetic factors with DM development, which will inform the personalized recommendations for OCM nutrients intakes on DM prevention.

Due to the multifactorial and multisystemic nature of diabetes mellitus, it is often treated with a combination of therapeutic agents having different mode of action. Earlier, we have synthesized several organozinc complexes and evaluated their safety and antidiabetic properties in experimental type 2 diabetes mellitus (T2DM). More recently, we have synthesized a metformin-3-hydroxyflavone complex and studied its antidiabetic efficacy in experimental rats. In the present study, a new zinc-mixed ligand (metformin-3-hydroxyflavone) was synthesized, characterized by spectral studies and its antidiabetic properties was evaluated in HFD fed—low dose streptozotocin induced T2DM in rats. The hypoglycemic efficacy of the complex was evaluated through oral glucose tolerance test, homeostasis model assessment of insulin resistance, quantitative insulin sensitivity check index and by determining the status of important biochemical parameters. Oral administration of the complex at a concentration of 10 mg/kg body weight/rat/day for 30 days significantly improved the glucose homeostasis. The complex possesses significant antidiabetic properties relatively at a less concentration than metformin-3-hydroxyflavone complex in ameliorating hyperglycemia.
