Description

CDK9抑制剂的多晶型物及其制法和用途 技术领域
本发明属于医药技术领域,具体地,涉及一种CDK9抑制剂的多晶型物及其制法和用途。
背景技术
真核细胞的增殖分裂是一个精确而复杂的调控过程。增殖过程是通过细胞周期来完成的,细胞周期的有序进行是通过其严格的分子调控机制。目前已发现主要有三大类分子参与细胞周期调控:细胞周期蛋白依赖性激酶(cyclin-dependent kinases,CDK)、细胞周期蛋白(cyclins)、细胞周期蛋白依赖性激酶抑制剂(cyclin-dependent kinase inhibitors,CKI),其中CDK处于中心地位。CDK家族已发现13个成员(CDK1-CDK13),按其胞内功能不同分为两类:控制细胞周期的CDK和控制细胞转录的CDK。CDK9属于丝氨酸类激酶,它与对应细胞周期蛋白(cyclin)结合形成的复合物称为正性转录延长因子b(P-TEFb),该复合物能够磷酸化RNA聚合酶Ⅱ(RNApolymeraseⅡ)和一些负性转录延长因子(NELF和N-TEF)从而使转录从起始部位得以延伸,是转录得以延长的核心分子(Sims RJ 3rd等Genes Dev,2004,18:2437-68;Yamaguchi Y等Mol Cell Biol,2002,22:2918-27)。研究发现CDK9的表达水平或/和激酶活性的异常会引起细胞内多种蛋白表达或/和其mRNA水平异常。已经证实与肿瘤密切相关的就有抗凋亡蛋白(如Bcl-2)、细胞周期相关调节蛋白(如cyclin D1)、p53途径相关蛋白、NF-κB途径的某些蛋白和以及与肿瘤微环境有关的蛋白(如VEGF)等。可见CDK9是肿瘤发生发展过程中最关键分子之一。
因此,开发用于调节CDK9的药物对于预防和治疗与CDK9相关的疾病至关重要。

具体实施方式
本发明的式(I)化合物
本发明所述的式(I)化合物如下式所示,
Figure PCTCN2020094527-appb-000002
该化合物名称为4-(((4-(5-氯-2-(((1R,4r)-4-(((R)-1-甲氧基丙基-2-基)氨基)环己基)氨基)吡啶-4-基)噻唑-2-基)氨基)甲基)四氢-2H-吡喃-4-甲腈,其名称也可以为4-[[[4-[5-氯-2-[[反式-4-[[(1R)-2-甲氧基-1-甲基乙基]氨基]环己基]氨基]-4-吡啶基]-2-噻唑基]氨基]甲基]-四氢-2H-吡喃-4-氰基。该化合物的具体制备方法可参照CN108727363A中实施例1的制备方法,其可以用于抑制细胞周期蛋白依赖性激酶(cyclin-dependentkinases,CDK)、细胞周期蛋白(cyclins)的活性,尤其是CDK9的活性。
本发明中,“式(I)化合物”与“式(I)化合物游离碱”可互换使用。
本发明的多晶型物
固体不是以无定形的形式就是以结晶的形式存在。在结晶形式的情况下,分子定位于三维晶格格位内。当化合物从溶液或浆液中结晶出来时,它可以不同的空间点阵排列结晶(这种性质被称作“多晶型现象”),形成具有不同的结晶形式的晶体,这各种结晶形式被 称作“多晶型物”。给定物质的不同多晶型物可在一个或多个物理属性方面(如溶解度和溶解速率、真比重、晶形、堆积方式、流动性和/或固态稳定性)彼此不同。
所述的“结晶”可以通过操作溶液,使得感兴趣化合物的溶解度极限被超过,从而完成生产规模的结晶。这可以通过多种方法来完成,例如,在相对高的温度下溶解化合物,然后通过冷却溶液至饱和极限以下,或者通过沸腾、常压蒸发、真空干燥或其它的一些方法来减小液体体积,或者通过加入抗溶剂或化合物在其中具有低的溶解度的溶剂或这样的溶剂的混合物来降低感兴趣化合物的溶解度。另一种可选方法是调节pH值以降低溶解度。有关结晶方面的详细描述请参见Crystallization,第三版,J W Mullens,Butterworth-Heineman Ltd.,1993,ISBN 0750611294。
所述的“结晶”可通过将式(I)化合物和相应的酸或相应酸的溶液在合适的溶剂中混合形成浑浊液,或者将式(I)化合物与合适的溶剂混合形成浑浊液后搅拌得到晶体的一种方法。合适的溶剂可以为水或有机溶剂。
所述的“结晶”可通过将式(I)化合物的溶液或含式(I)化合物和相应酸的溶液置于一定温度下缓慢挥发掉溶剂来得到晶体。
本发明所述的“加入抗溶剂”或“加入反溶剂”是指向式(I)化合物的一种溶液中加入另一种合适溶剂后析出得到晶体的一种方法。
假如期望盐的形成与结晶同时发生,如果盐在反应介质中比原料溶解度小,那么加入适当的酸或碱可导致所需盐的直接结晶。同样,在最终想要的形式比反应物溶解度小的介质中,合成反应的完成可使最终产物直接结晶。
结晶的优化可包括用所需形式的晶体作为晶种接种于结晶介质中。另外,许多结晶方法使用上述策略的组合。一个实施例是在高温下将感兴趣的化合物溶解在溶剂中,随后通过受控方式加入适当体积的抗溶剂,以使体系正好在饱和水平之下。此时,可加入所需形式的晶种(并保持晶种的完整性),将体系冷却以完成结晶。
如本文所用,“本发明的晶体”、“本发明的晶型”、“本发明的多晶型物”等可互换使用。
如本文所用,术语“本发明的多晶型物”包括式(I)化合物或其药学上可接受盐(如马来酸盐、富马酸盐)的多晶型物,还包括相同盐的不同多晶型物。
优选地,本发明的多晶型物包括(但并不限于):式(I)化合物马来酸盐的晶型I、晶型1、晶型2、晶型3或晶型4;式(I)化合物富马酸盐的晶型A。
在本发明中,某些晶型可以相互转化,因此本发明还提供了部分晶型相互转化的方法。
多晶型物的鉴定和性质
本发明在制备式(I)化合物的多晶型物后,采用如下多种方式和仪器对其性质进行了研究,例如,X射线粉末衍射(XRD)、差示量热扫描分析(DSC)、TGA、IR等等。
X射线粉末衍射:测定晶型的X射线粉末衍射的方法在本领域中是已知的。例如使X射线粉末衍射仪,以2°每分钟的扫描速度,采用铜辐射靶获取图谱。
本发明的式(I)化合物的盐的多晶型物,具有特定的晶型形态,在X-射线粉末衍射(XRPD)图中具有特定的特征峰。
示差扫描量热分析:又称“差示量热扫描分析”(DSC),是在加热过程中,测量被测物质与参比物之间的能量差与温度之间关系的一种技术。DSC图谱上的峰位置、形状和峰数目与物质的性质有关,故可以定性地用来鉴定物质。本领域常用该方法来检测物质的相变温度、玻璃化转变温度、反应热等多种参数。

结果显示:式(I)化合物富马酸盐晶型A和式(I)化合物马来酸盐晶型1在高温下经过21天,含量基本无变化,XRPD图谱特征峰基本无变化,晶型十分稳定。
而将式(I)化合物游离碱无定形物同样地进行上述稳定性的研究。结果发现:式(I)化合物游离碱无定型物稳定性差,在第7天和第14天时,无定型物性状发生明显变化,由黄色固体变成类似硬胶状物,杂质种类增多,杂质含量增大。

实施例12吸湿性试验
实验方法:通过动态水分吸附仪来检测,称取10mg固体样品放置到天平上,程序控制样品室内湿度,在同一温度不同湿度的条件下放置7天,测定受试样品随相对湿度的质量变化。检测程序:湿度变化为0%-95%-0%;测试温度25℃。
实验结果如图15(实施例2制备的式(I)化合物马来酸盐的晶型1)和图16(实施例9制备的式(I)化合物富马酸盐晶型A)所示。结果显示:两种盐型吸湿性相当,在环境湿度RH=60%下,吸湿增重约1%,吸湿性弱,明显优于游离态。
而将式(I)化合物游离碱无定形物同样地进行上述吸湿性的研究。结果发现:式(I)化合物游离碱无定型物稳定性差,在环境湿度RH高于60%,表现出较强的吸湿性,且吸湿后的样品性状明显改变(有团聚现象)。送DVS检测,其结果如图20所示。可见,式(I)化合物游离碱无定形物具有较强的吸湿性,会随着环境湿度的增大,持续吸湿。在相对湿度95%时,吸湿增重可达9.5%,且吸湿后的样品不易脱附。

配置1000×化合物储存板(或称为1000×储存药板),将100mM的化合物储存液用 DMSO进行稀释,起始浓度10mM,9个浓度梯度(储液浓度分别为10mM、3mM、1mM、0.3mM、0.1mM、0.03mM、0.01mM、0.001mM和0.0001mM)。化合物储存板用封板胶带密封,放入-20℃冰箱保存备用。
选择急性髓系白血病细胞MV-4-11(购自ATCC),按照5000/孔的密度接种到96孔板中(每孔体积为140μL),放入37℃,5%CO 2培养箱中培养过夜。
取出1000×储存药板,室温避光融化,然后配制15×中间药板(78.8μL培养基加1.2μL含药DMSO储存液),充分混匀。转移10μL含药培养基(15×)到96孔细胞板中(终浓度为10μM、3μM、1μM、0.3μM、0.1μM、0.03μM、0.01μM、0.001μM和0.0001μM,DMSO终浓度为0.01%),轻拍混匀,然后放入37℃,5%CO 2培养箱中,继续培养24小时。
然后用CellTiter-Glo方法检测各个药物浓度条件下的细胞活力,并计算相应条件下的细胞增殖抑制率。
在MV-4-11细胞上,式(I)化合物马来酸盐晶型1在0.0001μM到0.01μM浓度范围内,细胞生长无明显变化,在0.03μM到10μM浓度范围内,对细胞生长有显著的抑制作用;式(I)化合物马来酸盐晶型1对MV-4-11细胞的绝对半数抑制浓度(ABsIC 50)为0.032μM。
对比例1
同样采用实施例1或实施例9描述的方法,用柠檬酸、L-酒石酸、硫酸或磷酸替换马来酸或富马酸,来与式(I)化合物成盐。结果发现,用柠檬酸、酒石酸、硫酸或磷酸与式(I)化合物成盐后根本无法获得晶体形态的固体。
对比例2
同样采用实施例1或实施例9描述的方法,用盐酸替换马来酸或富马酸,来与式(I)化合物成盐。结果发现,虽然盐酸与式(I)化合物成盐后可以获得晶体形态的固体,但是,式(I)化合物盐酸盐的吸湿性非常强,无法进行后续应用。
对比例3
经过挥发、冷却、溶析等方法对式(I)化合物游离碱无定形物进行结晶,结果都无法得到良好的晶体形态。
挥发:将利用表11所示溶剂完全溶解式(I)化合物游离碱后的溶液置于25℃真空烘箱中在真空(0.1MPa)挥发7天。结果发现所得物质均为油胶状物。再往这些油胶状物中加入相应等量的同种溶剂重新溶解,放置室温(T=20±2℃)下自然挥发。结果发现均未得到良好的固态样品。
