  • Title: The identification of 3-methylcholanthrene-9,10-dihydrodiol as an intermediate in the binding of 3-methylcholanthrene to DNA in cells in culture.
    Author: King HW, Osborne MR, Brookes P.
    Journal: Chem Biol Interact; 1978 Mar; 20(3):367-71. PubMed ID: 657396.
    Abstract:
    Two metabolites of 3-methylcholanthrene (3MC), previously shown to be precursors of the DNA-bound form of 3MC observed in embryo cells in culture, were prepared from 3MC by microsomal metabolism and isolated by high pressure liquid chromatography (HPLC). From HPLC analysis of the metabolites of 3MC, from mass spectrometric analysis and from comparison with the fluorescence spectra of all 5 possible dihydrodiols of the alkylated benzanthracenes, it was deduced that one of the precursor metabolites was a 9,10-dihydrodiol of 3MC while the other was a 1 or 2-hydroxy derivative thereof.
