    Abstract:
    Nitroarylmethyl quaternary (NMQ) ammonium salts of the basic DNA intercalator AMAC (N,N-dimethylaminoethyl-9-amino-5-methylacridine-4-carboxamide) are of interest as anticancer prodrugs. A sensitive HPLC assay has been developed for quantitation of AMAC and its NMQ prodrugs in cultured cells, plasma and tissue. Recovery of the prodrugs, without conversion to AMAC, was achieved using extraction in alkaline acetonitrile followed by immediate reneutralisation. Reversed-phase HPLC with fluorescence detection gave a detection limit of 3 fmol for AMAC, with linearity to 20 nmol (using diode array absorbance at high concentrations). This assay was used to measure cellular uptake, and hypoxic metabolism to AMAC, of three NMQ-AMAC prodrugs.
