Description
本申请是申请号为201680060384.3、申请日为2016年10月5日、发明名称为“ACP-196的晶型及其制备方法和药物组合物”的发明专利申请的分案申请。
技术领域
本申请涉及药物化学结晶技术领域。具体而言,本申请涉及ACP-196的晶型、其制备方法、药物组合物和用途。
背景技术
ACP-196是第二代布鲁顿氏酪氨酸激酶(BTK)抑制剂,可用于治疗或预防布鲁顿酪氨酸激酶介导的病症如慢性淋巴细胞白血病(CLL)。该药物通过持久地结合BTK而发挥作用。BTK是一连串蛋白链的一部分,该蛋白链将生长信号从CLL细胞表面传播到细胞核内的基因,使得癌症细胞得以生存和生长。通过阻断BTK,ACP-196可以使该生长信号的传递停止因而CLL细胞死亡。
ACP-196化学名称为4-[8-氨基-3-[(2S)-(1-(1-氧-2-丁炔-1-基)-2-吡咯烷基]咪唑并[1,5-a]吡嗪-1-基]-N-2-吡啶苯甲酰胺,英文名为Acalabrutinib,CAS号1420477-60-6,其化学结构式如下(II)所示:
专利文献CN103889987A报道了ACP-196的制备方法,并公开了ACP-196的液相色谱质谱联用(LCMS)数据。本发明人研究发现,按照CN103889987A中实施例6的制备方法得到的ACP-196为黄色无定型物,其具有晶型不稳定、易吸湿、流动性差的缺点。专利文献CN103889987A中还提及无定型和多种晶型等物理形式都在其保护范围之内,但该专利并没有提供任何这些物理形式的特征性数据,因此不能作为充分的公开内容。
鉴于现有技术尚存不足,本领域仍需要开发具有更多改进性能的结晶态的ACP-196,以满足药物制剂对于活性物质的形态、稳定性等物化性质的严格要求。
发明内容
针对现有技术的不足,本发明的目的是提供ACP-196的晶型以及它们的制备方法、包含所述晶型的药物组合物和用途。所述晶型为稳定的结晶态固体,应具有一种或多种改进的特性,特别在结晶度、吸湿性、形貌、制剂可加工性、晶型稳定性等方面。此外,本发明还涉及所述晶型的制备方法、包含所述晶型的药物组合物及其用途。
