Description

一种吡唑并杂芳基类衍生物的可药用盐的结晶形式
本申请要求申请日为2022/11/21的中国专利申请2022114519333的优先权。本申请引用上述中国专利申请的全文。
技术领域
本公开涉及一种吡唑并杂芳基类衍生物的可药用盐的结晶形式，具体地涉及式(I)所示化合物的可药用盐的结晶形式。
背景技术
无论是正常细胞还是肿瘤细胞中，每天都会出现成千上万次DNA的损伤。这使得DNA损伤修复在维持基因组的稳定性和细胞存活方面起到至关重要的作用。相比较于正常细胞，肿瘤细胞承受了更大的复制压力，携带更多的内源性DNA损伤，并且经常出现一个或多个DNA损伤修复通路的缺失。这使得肿瘤细胞的存活更加依赖于DNA损伤修复的顺利进行。
同源重组修复是DNA双链断裂的主要修复方式，以未受损的姐妹染色单体的同源序列作为其修复的模板复制受损处的DNA序列，精确修复DNA。这种修复方式主要发生在细胞的G2期和S期。ATR是同源重组修复通路中的关键酶，属于PIKK家族。当ATR/ATRIP复合物与覆盖了复制蛋白A(RPA)的受损DNA结合后，ATR被激活并通过磷酸化下游蛋白Chk1和SMARCAL等，调节细胞周期各个检查点，引起细胞周期阻滞；保证受损DNA的稳定性；提高dNTP浓度，促使DNA损伤得以修复。细胞周期S期中出现的DNA损伤修复主要由ATR通路完成，说明ATR对于保证细胞增殖非常重要。对于临床肿瘤样品的分析结果表明在多种肿瘤组织中，例如胃癌、肝癌、结直肠癌、卵巢癌、胰腺癌等，均观察到ATR表达水平升高。并且在卵巢癌、胰腺癌病人中，高水平的ATR往往伴随着较低的存活率。由此可见ATR是一 个重要的肿瘤治疗的靶标。
WO2021098811A公开了一系列新的ATR抑制剂，其中式(I)所示化合物具有良好的ATR抑制活性，其结构如下所示：
药用的活性成分及其中间体的晶型结构往往影响到他们的化学稳定性，结晶条件及储存条件的不同有可能导致化合物的晶型结构的变化，有时还会伴随着产生其他形态的晶型。一般来说，无定型的产品没有规则的晶型结构，往往具有其它缺陷，比如产物稳定性较差，析晶较细，过滤较难，易结块，流动性差等。因此，改善上述产物的各方面性质是很有必要的，我们需要深入研究找到晶型纯度较高并且具备良好化学稳定的新晶型。
