O6-Benzylguanine is an efficient irreversible inactivator of the DNA repair protein O6-alkylguanine-DNA alkyltransferase (AGT, also known as methylguanine DNA methyltransferase, or MGMT). AGT directly removes alkyl groups located on the O6-position of guanine from DNA, thereby restoring DNA integrity. O6-Benzylguanine is an antineoplastic agent that can be used to investigate the role of AGT in carcinogenesis and mutagenesis (Pegg 2011; Dolan et al.).
