title: A note on the complex metabolism of danthron infused into the rat.
abstract: Danthron infused intravenously in rats shows a complex dose-dependent pattern of metabolism and excretion. The metabolites, particularly the more polar ones, are in general excreted predominantly in bile, to a lesser extent in urine. They can be separated as metabolite groups according to polarity and molecular size on a Sephadex LH 20 column. The present paper describes a further study within a bile-derived metabolite group, which proved to be particularly heterogeneous. It contained more than a dozen metabolites, which were conjugates of four different aglycons including the parent danthron. 1H NMR spectral data for danthron monosulfate and monoglucuronide are also presented.
