After cardiac surgery, diabetic patients are especially at risk for low cardiac output syndrome, which can quadruple the risk for postoperative death. Attempts to prevent low cardiac output syndrome have focused on increasing myocardial tolerance to ischemia (preconditioning), which involves the myocardial mitochondrial ATP-regulated K-ATP channel. G-protein initiation, nitric oxide synthase, and protein kinase C. Unfortunately, the signal transduction pathways required for preconditioning are corrupted in diabetes. Effective antioxidant intervention during ischemia-reperfusion appears important for preserving myocardial function: thus, alleviating oxidant-mediated post-ischemic injury by increasing antioxidant defenses (cardioprotection) is an alternative to preconditioning. Our previous work suggests that propofol(2,6-diisopropylphenol), an intravenous anesthetic with antioxidant potential, may confer cardioprotection. In this paper, we describe the rationale and methodology of the Pro-TECT II Study, a Phase II randomized controlled trial designed to explore the relationships of biomarkers of oxidative or nitrosative stress in diabetes, to determine the effect of propofol cardioprotection to counteract these effects in patients undergoing elective primary coronary bypass graft surgery with cardiopulmonary bypass, and to provide feasibility and sample size data needed to conduct Phase III trials.

Both bis(maltolato)oxovanadium(IV) (BMOV), and the ethylmaltol analog, bis(ethylmaltolato)oxovanadium(IV) (BEOV), have the desired intermediate stability for pro-drug use, and have undergone extensive pie-clinical testing for safety and efficacy. Pharmacokinetic evaluation indicates a pattern of biodistribution consistent with fairly rapid dissociation and uptake, binding to serum transferrin for systemic circulation and transport to tissues, with preferential uptake in bone. These bis-ligand oxovanadium(IV) (VOL2) compounds have a clear advantage over inorganic vanadyl sulfate in terms of bioavailability and pharmaceutical efficacy. BEOV has now completed Phase I and has advanced to Phase II clinical trials. In the Phase I trial, a ran-e of doses horn 10 mg, to 90 mg BEOV, given orally to non-diabetic volunteers, resulted in no adverse effects, all biochemical parameters remained within normal limits. In the Phase IIa trial, BEOV (AKP-020). 20 mg, daily for 28 clays, per os, in seven type 2 diabetic Subjects, was associated with reductions in fasting blood and glucose and \%HbA1c; improved responses to oral glucose tolerance testing, versus, the observed worsening of diabetic symptoms in the two placebo controls.

In this review, emphasis will be on the most recent developments in the coordination chemistry of vanadium(III), (IV) and (V), as related to development of these compounds for pharmaceutical use. How best to measure bioactivity and the pharmaceutical relevance of accompanying increased oxidative stress will also be considered. (C) 2001 Elsevier Science B.V.
