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.

Low-dose hyper-radiosensitivity (HRS) is the phenomenon whereby cells exposed to radiation doses of less than approximately 0.5 Gy exhibit increased cell killing relative to that predicted from back-extrapolating high-dose survival data using a linear-quadratic model. While the exact mechanism remains

We introduce here a new class of BODIPY-based Ca2+ indicators which can be derivatized with biological ligands that permit the localization of the indicators in living cells. The underivatized BODIPY-based Ca2+ indicator (BOCA-1) shows a 250-fold increase in fluorescence intensity

HSC transplantation using genetically modified autologous cells is a promising therapeutic strategy for various genetic diseases, cancer, and HIV. However, for many of these conditions, the current efficiency of gene transfer to HSCs is not sufficient for clinical use. The
