Enhancement of platinum-induced cytotoxicity by O6-benzylguanine.


O(6)-Benzylguanine (O(6)-BG), a potent inactivator of the DNA repair protein O(6)-alkylguanine-DNA alkyltransferase (AGT), is presently in clinical trials combined with alkylating agents that modify the O(6) position of DNA guanine residues, i.e., 1,3-bis(2-chloroethyl)-1-nitrosourea and temozolomide. Previous work demonstrated that O(6)-BG also enhances… (More)
