Effect of Glucose-lowering of Heteropolytungstogermanate β-K_6H[GeW_9V_3O_(40)]·9H_2O

IntroductionThe main abnormality in insulin- dependentdiabetes mellitus is heperglycemia due to thedeficiency of insulin. At present severe diabetescan be controlled only by dialy injections of insulin,so the development of some compounds that servethe function of insulin or as insulin mimetics onoral administration would be very helpful.The finding in 1 985 that vanadate ( + 5oxidation state of vanadium) shows an in vivoinsulin- like effect stimulated the research oninsulin- mimetic vanadium[…
