arrest in response to DNA damage. In the last decade, Chk1 inhibitors have emerged as a novel therapeutic strategy to potentiate the anti-tumour efficacy of cytotoxic chemotherapeutic agents. In the search for new Chk1 inhibitors, a congeneric series of 2-aryl-2 H-pyrazolo[4,3-c]quinolin-3-one (PQ) was evaluated by in-vitro and in-silico approaches for the first time. A total of 30 PQ structures were synthesised
丝氨酸-苏氨酸检查点激酶1(Chk1)在细胞周期停滞中起着至关重要的作用,以响应DNA损伤。在过去的十年中,Chk1抑制剂已成为增强细胞毒性化学治疗剂抗肿瘤功效的新型治疗策略。在寻找新的Chk1抑制剂时,首次通过体外和计算机模拟方法评估了同类的2-芳基-2 H-吡唑并[4,3-c]喹啉-3-酮(PQ)。 。使用常规或微波加热以良好至极好的产率合成了总共30个PQ结构,突出显示其中14个是新的化学实体。值得注意的是,在这项初步研究中,两种化合物4e2和4h2已显示Chk1激酶的基础活性适度但显着降低。从这些初步结果开始,
