Abstract

A series of bisubstrate inhibitors for DNA N6 adenine methyltransferase (Dam) have been synthesized by linking an amine analogue of S-adenosylmethionine to an aryl moiety designed to probe the binding pocket of the DNA adenine base. An initial structure-activity relationship study has identified substituents that increase inhibitor potency to the ∼10 μM range and improve selectivity against the human cytosine methyltransferase Dnmt1.
