Biological Activity:
SCH51344 is a novel potent, selective and cell permeable inhibitor of the nudix hydrolase family MTH1 protein with an IC50 of ~49 nM. It inhibits Ras-induced malignant transformation. It has no effect on Ras-induced ERK and JNK activation. SCH51344 inhibits Ras-induced membrane ruffling in REF-52 fibroblasts and blocks anchorage-independent growth of Ras-transformed tumor cell lines. It also induces DNA damage in SW480 colon cancer cells. Loss-of-function of MTH1 impaired growth of KRAS tumor cells, whereas MTH1 overexpression mitigated sensitivity towards SCH51344.


How to Use:


  • In vitro:  SCH51344 was used at 5-20 µM final concentration in various in vitro and cellular assays.
  • In vivo: n/a
