General description

Inhibition of 8-oxoguanine DNA glycosylase-1 (OGG1) can be used in monotherapy or in combination therapy to treat some types of cancer.

Biochem/physiol Actions

OGG1 Inhibitor O8 is a potent inhibitor of 8-Oxoguanine DNA Glycosylase-1 (OGG1), part of the DNA base excision repair (BER) pathway that is becoming a drug target for cancer therapy. OGG1 Inhibitor O8 has an IC50 value of 220 nM and >100-fold selectivity for OGG1 relative to several other DNA repair glycosylases. O8 acts through the inhibition of Schiff base formation during OGG1 catalysis. It does not prevent DNA binding of OGG1 to a 7,8-dihydro-8-oxoguanine (8-oxo-Gua)-containing substrate.

The DNA base excision repair (BER) pathway, which utilizes DNA glycosylases to initiate repair of specific DNA lesions, is the major pathway for the repair of DNA damage induced by oxidation, alkylation, and deamination. Early results from clinical trials suggest

Background: Oncogenic transformation is associated with elevated oxidative stress that promotes tumor progression but also renders cancer cells vulnerable to further oxidative insult. Agents that stimulate ROS generation or suppress antioxidant systems can drive oxidative pressure to toxic levels selectively

The primary cause of morbidity and mortality from infection with respiratory syncytial virus (RSV) is the excessive innate immune response(s) (IIR) in which reactive oxygen species (ROS) play key role(s). However, the mechanisms for these processes are not fully understood.

PARP1 and PARP2 play critical roles in regulating DNA repair and PARP inhibitors have been approved for the treatment of BRCA1/2-mutated ovarian and breast cancers. It has long been known that PARP inhibition sensitizes cancer cells to DNA-damaging cytotoxic agents

8-Oxoguanine DNA glycosylase1 (OGG1)-initiated base excision repair (BER) is the primary pathway to remove the pre-mutagenic 8-oxo-7,8-dihydroguanine (8-oxoG) from DNA. Recent studies documented 8-oxoG serves as an epigenetic-like mark and OGG1 modulates gene expression in oxidatively stressed cells. For this
