Description: AZ32 is an orally bioavailable and blood-brain-barrier penetrating ATM inhibitor (AZ32) that radiosensitizes intracranial gliomas in mice. AZ32 was highly efficient in vivo as radiosensitizer in syngeneic and human, orthotopic mouse glioma model compared with AZ31. AZ32 is the first ATMi with oral bioavailability shown to radiosensitize glioma and improve survival in orthotopic mouse models.

Additional Information

Inhibition of ataxia-telangiectasia mutated (ATM) during radiotherapy of glioblastoma multiforme (GBM) may improve tumor control by short-circuiting the response to radiation-induced DNA damage. A major impediment for clinical implementation is that current inhibitors have limited CNS bioavailability, thus, the goal was to identify ATM inhibitors (ATMi) with improved CNS penetration.
