Abstract

O 6-Benzylguanine is an irreversible inactivator of O 6-alkylguanine-DNA alkyltransferase currently in clinical trials to overcome alkyltransferase-mediated resistance to certain cancer chemotherapeutic alkylating agents. In order to produce more soluble alkyltransferase inhibitors, we have synthesized three aminomethyl-substituted O 6-benzylguanines and the three methyl analogs and found that the substitution of aminomethyl at the meta-position ...
