英文摘要：

Objoctive To design and synthesize oxovanadium carboxylate coordination compounds, and to their hypoglycemic effects in alloxan - diabetic mice. Methods The chemical structure of the complexes was determined by elemental analysis, IR, UV, MS and H - NMR spectra. The effects of the compounds on the blood glucose concentrations and preliminary toxicity were investigated in alloxan - induced diabetic mice. Resuits Three oxovanadium carboxylate coordination compounds have been synthesized successfully. After 3 weeks administration, diglycollato oxovanadium （VO- DA） significantly reduced the fasting and post -prandial blood glucose level in alloxan -diabetic mice. All the compounds have some adverse effects of gastrointestinal tract. Conclusion VO- DA certainly has anti -diabetic effect in alloxan- induced diabetic mice.
