AZD0156 ATM Inhibitor

Cat.No.S8375

AZD0156 is a potent and selective inhibitors of ATM kinase, with potential chemo-/radio-sensitizing and antineoplastic activities. AZD0156 prevents DNA damage checkpoint activation, disrupts DNA damage repair, induces tumor cell apoptosis, and leads to cell death of ATM-overexpressing tumor cells.

Mechanism of Action

Targets/IC50/Ki
ATM
In vitro
AZD0156 shows sub-nanomolar potency in cell based assays of ATM inhibition with selectivities of greater than 1000 fold over other members of the PIKK family of enzymes.
In vivo
AZD0156 is a permeable, highly soluble compound with excellent preclinical pharmacokinetic properties including oral bioavailability. This compound shows robust efficacy in mouse xenograft models after oral administration when combined with DSB inducing agents. It is currently undergoing early clinical assessment.
