Descripción

Application

O⁶-Benzylguanine has been used:

• as an inhibitor of methylguanine methyltransferase (MGMT) in glioblastoma stem cell
• as a O6-alkylguanine-alkyltransferase (AGT) enzyme inhibitor in embryonic stem cells prior to N-ethyl-N-nitrosourea(ENU) treatment
• as an inhibitor of AGT in growth inhibition assays of HL-60 human promyelocytic leukemia cells

Biochem/physiol Actions

O⁶-Benzylguanine (O6BG) inhibits methylguanine methyltransferase (MGMT) by blocking the active site through benzyl group transfer. The use of O6BG with bis-chloroethylnitrosourea (BCNU) or carmustine is effective in treating solid tumors including lymphomas, melanomas and sarcoma.

O(6)-benzylguanine is an antineoplastic agent that binds the DNA repair enzyme O(6)-alkylguanine DNA alkyltransferase (AGT), resulting in inhibition of AGT-mediated DNA repair. It is widely used in various DNA repair mechanism studies and potentiates the effects of other chemotherapeutic agents that damage DNA.
