Description

O6-Benzylguanine, a guanine analog, is the DNA repair enzyme O6-alkylguanine-DNA alkyltransferase (MGMT/AGT) inhibitor. O6-Benzylguanine acts as an AGT substrate, which transfers its benzyl group to the AGT cysteine residue, thereby irreversibly inactivating AGT and preventing DNA repair. O6-Benzylguanine induces tumor cell apoptosis. Antineoplastic activity.

How to use

In Vitro:

The L3.6pl cells are relatively sensitive to O6-Benzylguanine (24-72 hours) in a dose- and time-dependent manner. The IC50 is 50 μg (at 48 hours). O6-Benzylguanine (50 μg; 48 hours) modulates p53 downstream target protein expression, induces apoptosis, and decreases cell proliferation. O6-Benzylguanine (50 μg; 48 hours) significantly decreases the MGMT transcriptional activity in L3.6pl.

In Vivo:

O6-Benzylguanine (100 μg; i.p.; daily for 35 days) inhibits pancreatic cancer cell growth and increases pancreatic cell sensitivity to Gemcitabine (100 mg/kg). O6-Benzylguanine inhibits pancreatic cancer cell proliferation and induces tumor cell apoptosis in vivo.
