The Uses of 6-O-Benzylguanine
An irreversible inhibitor of the mammalian DNA repair protein, O6-alkylguanine-DNA alkyltransferase. Assists in the protection against carcinogenic and therapeutic alkylating agents.
The Uses of 6-O-Benzylguanine
O6-Benzylguanine is an effective substrate and efficient inactivator of DNA alkyltransferase. O6-Benzylguanine is an inhibitor of MGMT. It is also used as an important raw material and intermediate used in organic Synthesis, pharmaceuticals, agrochemicals and dyestuff.
What are the applications of Application
O6-Benzylguanine is an effective substrate and efficient inactivator of DNA alkyltransferase
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.
