title: Inhibition of isolated rat liver RNApolymerases I and II by aminoacridines.
abstract: 9-Aminoacridine and 2 derivatives which contain hydroxyalkylic or aminoalkylic side chains in the 9-position totally inhibit the transcription of calf thymus DNA by rat liver RNA polymerases I and II. This inhibitory action does not always appear to be completely related to the ability of aminoacridines to intercalate into the DNA template.
