AZD1390

AZD1390 (AZD-1390) is a novel potent, selective, orally available and CNS penetrant ATM inhibitor with IC50 of 0.78 nM, displays >1,000-fold selectivity over closely related (PIKKs) and distant kinases; radiosensitises a panel of glioblastoma multiforme (GBM) cell lines and NCI-H2228 lung cells (IC50=3 nM) ; demonstrates potential in combination with radiation therapy for the treatment of brain tumors.Brain Cancer, Phase 1 Clinical (In Vivo) :Median survival of mice treated with AZD1390 and radiation are significantly longer than untreated control mice (p=0.001) . No overt signs of treatment toxicity are observed with small animal radiation research platform (SARRP) contrary to wholehead irradiated mice that seem to develop mucositis and difficulties drinking and eating at doses >10 Gy in combination with AZD1390.
