一种五元并六元杂环化合物的晶型及其制备方法和应用
本申请要求申请日为2022/9/8的中国专利申请2022111004551的优先权。本申请引用上述中国专利申请的全文。
技术领域
本发明涉及一种五元并六元杂环化合物的晶型及其制备方法和应用。
背景技术
JAK-STAT信号通路是近年来发现的一条由细胞因子刺激的信号转导通路,参与细胞的增殖、分化、凋亡以及免疫调节许多重要的生物学过程,与其他信号通路相比,这条信号通路的传递过程相对简单,它主要由三个组分组成,即酪氨酸激酶相关受体、酪氨酸激酶JAK和转录因子STAT。
JAK抑制剂可选择性抑制JAK激酶,阻断JAK/STAT通路,Janus激酶是一种非受体型酪氨酸蛋白激酶,有4个家族成员,分别是JAK1、JAK2、TYK2和JAK3,前3者广泛存在于各种组织和细胞中,而JAK3仅存在于骨髓和淋巴***。临床上JAK抑制剂主要用于筛选血液***疾病、肿瘤、类风湿性关节炎及银屑病等治疗药物。
JAK-STAT通路广泛存在于机体内各种组织细胞内,尤其对淋巴细胞系的分化、增殖、抗感染具有重要作用,并参与多种炎症因子的相互作用和信号转导,该通路的异常活化与多种疾病密切相关,寻找与筛选JAK抑制剂有助于深入研究JA-STAT的调控机制,进而为防治相关疾病提供新的药物及手段。另外,肿瘤的发生、生长、侵袭和转移与JAK-STAT信号转导通路有关,正常信号转导中STATs的激活快速而短暂,STATs的持续性激活与细胞的恶性转化进程密切相关。
最新的研究表明:器官移植排斥、银屑病、组织和器官纤维化、支气管哮喘、缺血性心肌病、心力衰竭、心肌梗死、血液***疾病以及免疫***疾病都与JAK-STAT信号转导通路密切相关,这条信号通路不但对维持细胞的正常的生理功能具有重要意义,而且对疾病的发生和发展也有重要的调控作用。
WO2014/111037公开了一种五元并六元杂环化合物的JAK激酶抑制剂,具有式1如下结构:
众所周知,多晶型是药物生产中普遍存在的现象,不同晶型在热力学、动力学和物理性质等方面 有较大差异,可能对原料药及制剂的稳定性、制剂的生产工艺、溶出度及生物利用度等产生影响,进而可能影响药物的安全性、有效性和质量可控性,所以药物的多晶型研究一直是制药行业关注的焦点。所以研究开发出一种具有较好的流动性,溶解性,储存稳定性,很好的生物利用度等的优势晶型对于药品的生产、储存、运输等至关重要。

术语“治疗有效量”是指给予患者的、足以有效治疗疾病的量。治疗有效量将根据化合物种类、疾病种类、疾病的严重度、患者的年龄等变化,但可由本领域技术人员视情况调整。
术语“药用辅料”是指除活性药物成分以外,包含在药物制剂中的所有物质,一般分为赋形剂和附加剂两大类。具体可参见《中华人民共和国药典(2020年版)》、Handbook of Pharmaceutical Excipients(Paul J Sheskey,Bruno C Hancock,Gary P Moss,David J Goldfarb,2020,9th Edition)。

本发明的晶型可以通过一种或几种固体分析方法进行鉴定。如X-射线粉末衍射、单晶X-射线衍射、红外吸收光谱、差示扫描量热、热失重曲线等。本领域技术人员知道,X-射线粉末衍射的峰强度和/或峰情况可能会因为实验条件不同而不同。同时,由于仪器不同的精确度,测得的2θ值会有约±0.2°的误差,而峰的相对强度值比峰的位置更依赖于所测定样品的某些性质,如晶体的尺寸大小,纯度高低,因此测得的峰强度可能出现约±20%的偏差。尽管存在实验误差、仪器误差和取向优先等,本领域技术人员还是可以从本专利提供的X-射线粉末衍射数据获得足够的鉴别各个晶型的信息。在红外光谱测定中,由于各种型号的仪器性能不同、供试品制备时研磨程度的差异或吸水程度不同等差异,对光谱的形状及吸收峰的位置均会有一定程度的影响。而在DSC测量中,根据加热速率、晶体形状和纯度和其它测量参数,实际获得的吸热峰的初始温度、最高温度和熔化热数据均具有一定程度的可变性。
本发明中,“室温”指“10~30℃”。
在不违背本领域常识的基础上,上述各优选条件,可任意组合,即得本发明各较佳实例。
本发明所用试剂和原料均市售可得。
本发明的积极进步效果在于:本发明提供的式1所示化合物的晶型II和晶型III具有较好的物理化学稳定性,不易吸湿,对药物的优化和开发具有非常重要的价值。
