AZD-6738 (AZD6738, Ceralasertib) 是一种有效的选择性 ATR 抑制剂，IC50 为 1 nM；对 ATM、DNA-PK 和 mTOR 无显着活性；抑制细胞中 ATR 激酶依赖性 CHK1 磷酸化 (IC50=74 nM)；增强顺铂在异种移植模型中的治疗效果；口服活性和生物利用度。

AZD-6738 (AZD6738, Ceralasertib) is a potent and selective inhibitor of ATR with IC50 of 1 nM; shows no significant activity for ATM, DNA-PK and mTOR; inhibits ATR kinase-dependent CHK1 phosphorylation in cells (IC50=74 nM); enhances the therapeutic efficacy of cisplatin in xenograft models; orally active and bioavailable.Gastric Cancer Phase 2 Clinical(In Vitro):Ceralasertib (AZD6738) is a potent inhibitor of ATR kinase activity with an IC50 of 0.001 μM against the isolated enzyme and 0.074 μM against ATR kinase-dependent CHK1 phosphorylation in cells. Ceralasertib (AZD6738) induces cell death and senescence in non-small cell lung cancer (NSCLC) cell lines. Ceralasertib (AZD6738) impairs viability of four Kras mutant cell lines: H23, H460, A549, and H358. , with the lowest GI50 and greatest maximal inhibition in H460 and H23 cells (1.05 μM, 88.0% and 2.38 μM, 86.2%, respectively). Ceralasertib (AZD6738) potentiates the cytotoxicity of CDDP and NSC 613327 in NSCLC cell lines with intact ATM kinase signaling, and potently synergizes with CDDP in ATM-deficient NSCLC cells. Ceralasertib (AZD6738) inhibits human breast cancer cell lines with IC50 values less than 1 μM using MTT assay. Ceralasertib (AZD6738) induces cell cycle arrest and apoptosis. It downregulates DNA damage response molecules and cell proliferative signaling molecules.(In Vivo):Daily administration of Ceralasertib (AZD6738) and ATR kinase inhibition for 14 consecutive days is tolerated in mice and enhances the therapeutic efficacy of CDDP in xenograft models. Remarkably, the combination of CDDP and Ceralasertib (AZD6738) resolves ATM-deficient lung cancer xenografts.
