Mechanism of Action

Targets/IC₅₀/Ki	ATR (Cell-free assay) 1 nM
In vitro	In four Kras mutant cell lines: H23, H460, A549, and H358, Ceralasertib (AZD6738) inhibits ATR kinase activity and impairs cell viability. In ATM-deficient H23 cells, it strongly synergizes with NSC 119875 to induce rapid cell death. In p53 or ATM defective cells, this compound treatment results in replication fork stalls and accumulation of unrepaired DNA damage, resulting in cell death by mitotic catastrophe.
In vivo	In nude mice bearing H460 and H23 tumors, Ceralasertib (AZD6738) (50 mg/kg, p.o.) results in tumor growth inhibition (TGI), and its combination with NSC 119875 causes rapid regression of ATM-deficient H23 tumors. In nude mice bearing LoVo xenografts, a combination of this compound (50 mg/kg) + IR (2 Gy) avoids toxicity while still maintaining efficacy.
