Description

恩曲替尼晶型及其制备方法 技术领域
本发明是涉及药物化学领域,尤其涉及恩曲替尼的晶型及其制备方法。
背景技术
恩曲替尼,英文名Entrectinib,其化学名为:N-(5-(3,5-二氟苄基)-1H-吲唑-3-基)-4-(4-甲基哌嗪-1-基)-2-((四氢-2H-吡喃-4-基)氨基)苯甲酰胺,商品名为:Rozlytrek,分子式为:C 31H 34F 2N 6O 2,分子量为:560.64,CAS号为:1108743-60-7,化学结构式为:
Figure PCTCN2021070965-appb-000001
该药是由罗氏开发的一种治疗NTRK融合阳性的晚期或复发性实体瘤的疾病,于2019.6.19在日本申请上市。
专利WO2013174876公开了恩曲替尼的晶型1、晶型2和晶型3及其制备方法。其中,晶型1和晶型2是无水物,晶型3为乙酸乙酯和正己烷的溶剂化物,晶型2晶型稳定性较好,晶型1晶型稳定性差容易转为晶型2。
专利WO2017202674公开了恩曲替尼的无水物晶型4,其在40℃以上晶型热力学稳定性更好。
显然,现有的恩曲替尼晶型1存在晶型稳定性差的问题,晶型2和晶型4存在溶解性较差的问题。而且,根据FDA资料显示,恩曲替尼是低溶解度药物。
综上所述,本领域迫切需要开发一种既具有良好溶解性又有良好晶型稳定性的新晶型,以满足制剂药用的需要。
