具体实施方式
本发明人经过长期而深入的研究,通过大量筛选、工艺优化获得了一种纯度更 高、成药性能更优的式I化合物的晶型。在此基础上,发明人完成了本发明。
如本文所用,术语“n个或n个以上选自下组的2θ值”指包括n以及大于n的任意正整数(例如n、n+1、….),其中上限Nup为该组中所有2θ峰值的个数。例如“1个或1个以上”不仅包括1、2、3、4、5、6、7、8、9、10、11、12、13、14、15、16、17、18、19、20、21、…上限Nup各个正整数,还包括“2个或2个以上”、“3个或3个以上”、“4个或4个以上”、“5个或5个以上”、“6个或6个以上”、“7个或7个以上”、“8个或8个以上”、“9个或9个以上”、“10个或10个以上”等范围。例如“3个或3个以上”不仅包括3、4、5、6、7、8、9、10、11、12、13、14、15、16、17、18、19、20、21、…上限Nup各个正整数,还包括“4个或4个以上”、“5个或5个以上”、“6个或6个以上”、“7个或7个以上”、“8个或8个以上”、“9个或9个以上”、“10个或10个以上”等范围。
与现有技术相比,本发明具有以下主要优点:
(1)相比WO2017173999 A1公开的化合物,本发明的晶型为最稳定的晶型;同时,本发明公布的结晶和纯化方法成本更低,更利于放大生产的操作过程;
(2)相比WO2017173999 A1,本发明通过优化工艺获得了一种纯度高、收率高、且杂质含量显著降低的晶型;
(3)相比WO2017173999 A1,其获得的无定形产品在放置过程中会有析晶的风险,固态稳定性较差。通过本发明获得的晶型,其固态稳定性更高,更利于长期储存。数据同时显示该晶型化学稳定性能很好,期间产生的杂质少,且具有统计学意义,使得原料药的储存期更长。
下面结合具体实施例,进一步阐述本发明。应理解,这些实施例仅用于说明本发明而不用于限制本发明的范围。下列实施例中未注明具体条件的实验方法,通常按照常规条件或按照制造厂商所建议的条件。除非另外说明,否则百分比和份数按重量计算。
除非另行定义,文中所使用的所有专业与科学用语与本领域熟练人员所熟悉的意 义相同。此外,任何与所记载内容相似或均等的方法及材料皆可应用于本发明方法中。文中所述的较佳实施方法与材料仅作示范之用。

结果
1)在固态性质方面,经重复,WO2017173999 A1实施例3中经手性拆分得到的化合物I白色固体为无定形(其XRPD结果请参见本发明图31)。
具体地,WO2017173999 A1实施例3中制得的化合物I白色固体为无定形,未能得到单一性状稳定的晶型,其固态稳定性较差。此类方法制备的原料药存在固态稳定性的不确定性,长期放置也存在进一步析晶的风险。对应样品的溶解度和生物利用度存在不确定性,成药性较差。
2)在化学纯度方面,WO2017173999 A1实施例3中报道的产品纯度仅为98.47%。与本发明实施例1中得到的产品纯度99.90%相比,纯度差距较大。鉴于WO2017173999 A1实施例3的合成中最后三个化学步骤的中间体3-(4-乙酰氨基-3-硝基苯乙基)-2-(3-(4-氟苯基)-1-(4-溴苯基)-1H-吡唑-4-基)噁唑烷-4-酮、3-(4-氨基-3-硝基苯乙基)-2-(1-(4-溴苯基)-3-(4-氟苯基)-1H-吡唑-4-基)噁唑烷-4-酮、2-(1-(4-溴苯基)-3-(4-氟苯基)-1H-吡唑-4-基)-3-(3,4-二氨基苯乙基)噁唑啉-4-酮在AMES实验中均显示为阳性,存在潜在风险。在原料药中这三种杂质的残留会严重影响原料药的质量。而本发明公开的晶型A及其制备和纯化有效避免了相关中间体的使用,同时纯度普遍在99.5%以上,更优的可以达到99.90%, 有效减少了各种有害杂质在原料药中的残留。

图20为晶型G的TGA/DSC图。
从图20可知:分解前几乎无失重,在220.3℃和222.0℃(峰值)处分别有吸热峰/放热峰,在246.1℃(起点)有一个尖锐的吸热峰。
结合图17,表明晶型G为无水晶型。
图22是晶型A/B/D/E/F/G的XRPD对比图。
从图22可知:化合物I共有六种晶型,包括晶型筛选实验中发现的四种(命名为晶型A/B/D/E)和后续晶型鉴定中发现的两种(命名为晶型F/G)。其中,无水晶型有三种(晶型A/F/G),水合物有一种(晶型E),溶剂合物有两种(晶型B/D)。
实施例3 晶型关系研究
无水晶型关系研究
晶型研究中共发现三种无水晶型,其中晶型F室温条件下不稳定,放置后转成水合物晶型E。为了研究其余无水晶型间(晶型A/G)的稳定性关系,在室温和60℃条件下选择ACN和EtOAc为溶剂设置了混悬竞争实验。具体操作为:称量4份过量晶型A到4个HPLC小瓶中,2份加入0.5mL ACN,另2份加入0.5mL EtOAc,分别放置在室温和60℃磁力搅拌~2小时,用预热的尼龙膜(孔径0.22μm)过滤得到饱和溶液;向饱和滤液中加入化合物I无水晶型A/G各~4mg,在室温或60℃磁力搅拌~2天,离心分离固体用于XRPD测试。
结果(表1-7)表明,室温和60℃条件下两种溶剂中所得固体均为晶型A,结合晶型G熔化后重结晶转为晶型A,说明晶型A比晶型G热力学更稳定,XRPD结果见图23。

关键水活度研究
无水晶型关系研究表明化合物I无水晶型A室温下最稳定,因此选择晶型A与水合物晶型E进行关键水活度研究。具体为,室温条件下配制目标水活度(a w为0/0.2/0.4/0.6/0.8/1.0)的Acetone/H 2O混合溶剂待用,Acetone/H 2O体积比对应的体系水活度见表1-8;分别称~20mg晶型A样品到对应溶剂中,室温搅拌~2小时后得到悬浊液,用尼龙膜(孔径0.22μm)过滤;称取~4mg水合物晶型E和化合物I无水晶型A到HPLC小瓶中,对应加入上述滤液,室温搅拌3~13天收集XRPD数据。
实验结果(表1-8和图24/图25)显示,水活度(a w)为0~0.8时,所得固体为化合物I无水晶型A;水活度为1.0时,所得固体为水合物晶型E。由此说明室温下水活度为0~0.8时,化合物I无水晶型A更稳定,水活度为1.0时,水合物晶型E更稳定,化合物I无水晶型A和水合物晶型E的关键水活度为0.8~1.0。

实施例4 成药性能研究
吸湿性
采用DVS在25℃下对化合物I无水晶型A进行吸湿性评估。评估前,化合物I无水晶型A在0%RH条件下平衡,以脱去吸附在表面的水或溶剂。
由图26可知,化合物I无水晶型A在80%RH时增重为0.14%,表明样品几乎不吸湿,测试后样品的晶型不变(图27),表明具有良好的晶型稳定性。
固态稳定性
为评估优选晶型(化合物I无水晶型A)的固态稳定性,称取~20mg样品在HPLC小瓶中,敞口置于1)25℃/60%RH,2)40℃/75%RH,3)60℃三种条件下。对起始样品、储存一周和两周的样品进行纯度测试(HPLC)和晶型检测(XRPD)。
结果显示,晶型A在所选条件下放置一周和两周后晶型均不变(图28和图29),纯度无明显变化(表1-9),表明晶型A具有良好的固态稳定性。
表1-9 晶型A的两周稳定性数据汇总
Figure PCTCN2022107465-appb-000033
结果显示:
1)化合物I无水晶型A几乎不吸湿,且DVS测试前后晶型不变,证明具有良好的晶型稳定性;
2)晶型A在25℃/60%RH、40℃/75%RH和60℃敞口放置两周后,晶型和纯度均无明显变化,表现出良好的固态稳定性。
溶解性
室温下,测试化合物I晶型A(D220-PS-01-A)在以下21种溶剂中的粗略溶解度。具体为,在HPLC小瓶中称量~2mg起始物料,逐次(50/50/200/700μL)加入下表中的溶剂,直至固体完全溶解或总体积达到1.0mL。所得数据汇总于表1-10。

Figure PCTCN2022107465-appb-000035
化合物I晶型A在水中的溶解度较低,易溶于DMSO、DMF、THF和乙酸。所以针对晶型A的提纯重结晶工艺,选择在醋酸中进行。化合物I晶型A在丙酮中的溶解度中等,所以选择在丙酮中打浆进一步提纯,以去除结构类似的杂质以及相关中间体。
结论
通过对化合物I进行的一系列晶型筛选实验,共发现六种晶型,包括三种无水晶型(晶型A/F/G)、一种水合物晶型E和两种溶剂合物(晶型B/D)。无水晶型间的关系通过熟化/加热和混悬竞争进行研究,结果表明化合物I无水晶型A在室温(~18℃)/60℃最为稳定。化合物I无水晶型A和水合物晶型E的稳定性关系在不同水活度下进行研究,结果表明,室温下水活度0~0.8时,化合物I无水晶型A更稳定;水活度1.0时,水合物晶型E更稳定,表明化合物I无水晶型A和水合物晶型E的关键水活度为0.8~1.0。化合物I无水晶型A的吸湿性评估表明,晶型A几乎不吸湿,DVS测试前后晶型不变;同时化合物I无水晶型A的固态稳定性评估表明,在25℃/60%RH、40℃/75%RH和60℃下敞口放置两周后晶型和纯度均无明显变化,表现出较好的固态稳定性。
晶型F和G未从溶液法中获得,晶型F在室温(18~20℃,45%~75%RH)放置3天转为水合物晶型E,表明室温下不稳定;晶型G熔融后重结晶可转成晶型A。对晶型A和G进行混悬竞争,结果表明,在室温和60℃下ACN和EtOAc中晶型G均能转成晶型A,表明晶型A相比晶型G热力学更稳定。
各晶型间的相互转化关系可参考图30,条件说明见表1-11。
