O6-Benzylguanine

O6-Benzylguanine (O6-BG) is a synthetic derivative of guanine. It is an antineoplastic agent. It exerts its effect by acting as a suicide inhibitor of the enzyme O6-alkylguanine-DNA alkyltransferase which leads to interruption of DNA repair. O6-BG was used clinically in combination with the alkylating agent temozolomide for glioblastoma, however the combination was found to be overly toxic without adding significant benefit.

O6-BG is also used as a biochemical tool in the study of DNA repair mechanisms.
