While both vanadate and vanadyl forms of vanadium are orally active, they are still not well absorbed. We have synthesized several organic vanadium compounds and one compound, bis(maltolato)oxovanadium(lv) or BMOV, has been extensively investigated. BMOV proved effective in lowering plasma glucose and lipids in STZ-diabetic: rats when administered in drinking water over a 25 week period. The maintenance dose (0.18 mmol/kg/day) was approximately 50\% of that required for vanadyl sulfate (VS). Secondary complications of diabetes were prevented by BMOV and no marked toxicity was noted. Oral gavage of STZ-diabetic rats with BMOV also reduced blood glucose levels. The ED(50) for BMOV was 0.5 mmol/kg, while for VS the estimated ED(50) was 0.9 mmol/kg. BMOV was also effective by the intraperitoneal route in STZ-diabetic rats. The ED(50) was 0.08 mmol/kg compared to 0.22 mmol/kg for VS. Some animals treated p.o. or i.p. remained euglycemic for up to 14 weeks. An i.v. infusion of BMOV of 0.05 mmol/kg over a 30 min period reduced plasma glucose levels by 50\% while VS was not effective.}, keywords = {ADIPOCYTES, BIS(MALTOLATO)OXOVANADIUM(IV), diabetes, DIABETIC, GLUCOSE, HYPERTENSION, IMPROVEMENT, INSULIN ACTION, insulin-mimetic, RATS, RECEPTOR TYROSINE KINASE, resistance, SPONTANEOUSLY HYPERTENSIVE RATS, VANADATE, VANADIUM}, isbn = {0300-8177}, url = {://A1995TM62000024}, author = {McNeill, J.
