Bioactivity	AZD-7762 hydrochloride is a potent ATP-competitive checkpoint kinase (Chk) inhibitor in with an IC50 of 5 nM for Chk1.
Invitro	AZD-7762 hydrochloride 在体外是一种同样有效的 Chk1 和 Chk2 抑制剂。AZD-7762 hydrochloride 有效抑制 Chk1 和 Chk2，消除 DNA 损伤诱导的 S 和 G2 检查点，增强 NSC 613327 和 SKF 104864A 的功效，并调节下游检查点通路蛋白。AZD-7762 hydrochloride 有效抑制 cdc25C 肽的 Chk1 磷酸化，通过闪烁亲近测定法测量，IC50 为 5 nM。AZD-7762 hydrochloride 的 Ki 确定为 3.6 nM。动力学表征表明 AZD-7762 hydrochloride 结合在 Chk1 的 ATP 结合位点，并被认为以可逆方式直接竞争 ATP 结合。AZD-7762 hydrochloride 显示可消除喜树碱诱导的 G2 阻滞，平均 EC50 为 10 nM (n=12)，最大消除范围为 100 nM[1]。
In Vivo	在大鼠 H460-DNp53 异种移植研究中，AZD-7762 hydrochloride（10 mg/kg 和 20 mg/kg）以剂量依赖性方式增强 NSC 613327 的抗肿瘤活性。即随着剂量增加，抑制率 (%T/C) 分别降低至 48% 和 32%。在与 CPT-11 联合的小鼠异种移植研究中，AZD-7762 hydrochloride 与 CPT-11 联合处理，可显著增加 CPT-11 活性，%T/C 分别显着增加至 -66% 和 -67%[1]。AZD7762 hydrochloride 与 CX-5461 联合使用，在体外和体内诱导 Tp53-null (Tp53-/-) Eμ-Myc 淋巴瘤细胞死亡[2]。
