The present invention provides 8-substituted O6 -benzylguanines of the formula STR1 wherein R1, R2, and R3 are as defined in the specification, and 4(6)-substituted 2-amino-5-nitro-6(4)-benzyloxypyrimidine, and 4(6)-substituted 2-amino-5-nitroso-6(4)-benzyloxypyrimidine derivatives which have been found to be effective AGT inactivators, as well as pharmaceutical compositions comprising such derivatives along with a pharmaceutically acceptable carrier. The present invention further provides a method of enhancing the chemotherapeutic treatment of tumor cells in a mammal with an antineoplastic alkylating agent which causes cytotoxic lesions at the O6 -position of guanine, by administering to a mammal an effective amount of one of the aforesaid derivatives, 2,4-diamino-6-benzyloxy-s-triazine, 5-substituted 2,4-diamino-6-benzyloxypyrimidines, or 8-aza-O6 -benzylguanine, and administering to the mammal an effective amount of an antineoplastic alkylating agent which causes cytotoxic lesions at the O6 -position of guanine.
