The exceptional antitumor and mutagenic activities displa>-ed by a quinacrine derivative of a monofunctiolial nitrogen mustard, 2-methoxy-6-chloro-9-[~-(ethyl-2-chloroethyl) aminopropylamino] acridine, led to the synthesis of 50 additional mono-and difunctional analogs of acridine, quinoline, and quinazoline.
