Several new O6-benzylguanine analogs bearing increasingly bulky substituent groups on the benzene ring or at position 9 were tested for their ability to inactivate the human DNA repair protein, O6-alkylguanine-DNA alkyltransferase. Substitution on the benzene ring was well tolerated although activity varied considerably with structural changes in groups attached to position 9. For this site, activity was preserved with large or small lipophilic groups while introduction of non-carbohydrate polar groups generally reduced activity regardless of their size.
