Searching for a novel family of inactivators of the human DNA repair protein O-6-methylguanine-DNA methyltransferase (MGMT) which is known to bind to the DNA minor groove, we have computationally modelled and synthesised two series of 2-amino-6-aryloxy-5-nitropyrimidines with morpholino or aminodiaryl substituents (potential minor groove binders) at the 4-position. Synthesis of these compounds was achieved by successive substitution of each of the two Cl atoms of 2-amino-4,6-dichloro-nitropyrimidine by the corresponding amino and aryloxy derivatives. Biochemical evaluation of these compounds as MGMT inactivators showed poor activities, but in general the 4-bromothenyloxy derivatives showed better inactivation than the benzyloxy versions. DNA binding assessment was not possible due to insolubility problems. (C) 2011 Elsevier Ltd. All rights reserved.
