SCH 900776 is a potent and selective inhibitor of cell cycle checkpoint kinase 1 (Chk1), Chk2 and Cdk3 with IC50 value of 3 nM, 1.5µM and 0.16 µM, respectively.
Chk is s serine/threonine kinase that senses signal of DNA damage and stalls DNA replication, and also plays an essential role in the maintenance of replication fork viability during exposure to DNA antimetabolites.
In vitro, SCH 900776 blocked accumulation of the Chk1 pS296 autophosphorylation in a dose-dependent manner. Treatment of proliferating WS1 cells with SCH 900776 was found to be associated with rapid, dose-dependent accumulation of Chk1 pS345, indicating that cycling populations of normal cells induce Chk1 pS345 in response to the inhibition of SCH 900776 as part of a futile cycle 1.
In BALB/c mice, administration of SCH 900776 at a dosage of 8mg/kg after gemcitabine treatment can sufficiently induce enhanced tumor pharmacodynamic and regression responses as compared to gemcitabine or SCH 900776 alone 1.
