Biochem/physiol Actions

TH287 is a potent inhibitor of human 7,8-Dihydro-8-oxoguaninetriphosphatase MTH1 (NUDT1) with an IC50 value of 0.8 nM. MTH1 hydrolyzes oxidized purine nucleoside triphosphates that might otherwise be incorporated into DNA/RNA and contribute to DNA damage. MTH1 removal of oxidized nucleotides that result from increased levels of reactive oxygen species (ROS) in fast-proliferating cancer cells helps protect cancer cells from proliferative stress and prevent cancer cell death. TH287 is considered a new target for cancer therapy. TH287 is highly selective towards MTH1, with no relevant inhibition of other members of the nudix protein family. TH287 has been shown to selectively kill a variety of cancer cell lines, but is rapidly metablized, so not as useful for in vivo studies.

Epstein-Barr virus (EBV) immortalizes human B-lymphocytes and is implicated in the pathogenesis of lymphoid and epithelial cell malignancies. The EBV nuclear antigen (EBNA)-1 induces the accumulation of reactive oxygen species (ROS), which enables B-cell immortalization but causes oxidative DNA damage

Molecular cancer therapeutics, 19(2), 432-446 (2019-11-21)
Investigations into the human 8-oxodGTPase, MutT Homolog 1 (MTH1), have risen sharply since the first-in-class MTH1 inhibitors were reported to be highly tumoricidal. However, MTH1 as a cancer therapeutic target is currently controversial because subsequently developed inhibitors did not exhibit
