Biochem/physiol Actions


(S)-Crizotinib has a distinctly different profile from its (R)-enantiomer, the clinically approved anticancer agent Xalkori. Instead of targeting ALK, MET and ROS1, (S)-Crizotinib is a highly selective inhibitor of human 7,8-Dihydro-8-oxoguaninetriphosphatase MTH1 (NUDT1) with an IC50 value of 330 nM, 16-fold higher affinity towards MTH1 compared to the clinically used (R)-isomer. 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. It is considered a new target for cancer therapy. In mouse xenograft studies using SW480 cells, (S)-crizotinib but not the (R)-enantiomer, was able to impair overall tumour progression as well as specifically reduce tumour volume by more than 50%.
