NMR-spectroscopy-based metabonomic approach to the analysis of Bay41-4109, a novel anti-HBV compound, induced hepatotoxicity in rats.

An integrated metabonomics study using high-resolution (1)H nuclear magnetic resonance (NMR) spectroscopy has been applied to investigate the biochemical composition of urine, serum, liver tissue aqueous extracts (acetonitrile/water) and liver tissue lipidic extracts (chloroform/methanol) obtained from control and Bay41-4109 treated rats (10, 50, 400mg.kg(-1).d(-1) for 5 days, i.
