TH588 | MTH1/NUDT1 inhibitor

TH588 (1609960-31-7) is a first-in-class nudix hydrolase family inhibitor.1 MTH1/NUDT1 is a family member that “sanitizes” oxidized deoxynucleotide triphosphates (dNTP) preventing their incorporation into DNA and thus avoiding DNA damage and cell death.  TH588 inhibits MTH1/NUDT1 (IC50 = 5 nM) leading to cell death in several cancer cell lines while not affecting normal cells.  Active in vitro and in vivo.  Recent evidence has raised doubts about the cancer-killing ability of MTH1 inhibition.2,3 Conversely, TH588 has been also shown to decrease osteosarcoma cell viability, impair cell cycle, and increase apoptosis via an MTH1-dependent pathway.4
