nogalamycin and Carbon-Tetrachloride-Poisoning

Menogaril (TUT-7) is a novel antitumor antibiotic belonging to anthracyclines. The pharmacokinetic parameters derived from plasma concentration-time profiles after repeated (for 14 days) or single oral administration of TUT-7 to rats were found to be not significantly different by either administration schedule. The rats with artificial liver dysfunction were obtained by subcutaneous application of carbon tetrachloride (CCl4, 1 ml/kg) for 3 days. After oral administration of TUT-7 to the rats with CCl4-induced liver toxicity (3 daily administrations of 1mg/kg, S.C.), the maximum plasma concentrations (Cmax) and AUC of both the unchanged drug and its metabolite N-Demethyl menogaril, were increased. Also over all elimination was slower in animals with liver dysfunction.
