背景技术
真核染色质是由称为核小体的大分子复合物构成。核小体有147个碱基对的DNA包裹在一个蛋白质八聚体周围,这种蛋白质八聚体具有组蛋白H2A、H2B、H3和H4中的每一个的两个亚基。组蛋白经过转译后修饰,转译后修饰进而影响染色质结构和基因表达。组蛋白上发现的一种转译后修饰是赖氨酸和精氨酸残基的甲基化。组蛋白甲基化在真核生物的基因表达调控中起着关键作用。甲基化影响染色质结构,并与转录的激活和抑制有关(Zhang和Reinberg,《基因进化(Genes Dev)》,15:2343-2360,2001)。催化组蛋白与甲基附接和从其去除的酶与基因沉默、胚胎发育、细胞增殖和其它过程有关。
一类组蛋白甲基化酶的特征是存在包含约130个氨基酸的Zeste Trithorax(SET)结构域的变体增强子的抑制因子。Zeste同源物2的增强子(EZH2)是含有甲基化酶的人类SET结构域的实例。EZH2与EED(胚胎外胚层发育)和SUZ12(zeste 12同源物的抑制因子)结合以形成被称为Polycomb组抑制复合物2(PRC2)的复合物,所述复合物具有在赖氨酸27处三甲基化组蛋白H3的能力(Cao和Zhang,《分子细胞(Mol.Cell)15:57-67,2004)。PRC2复合物也可以包括RBAP46亚基和RBAP48亚基。另一个实例是相关的甲基化酶EZH1。
通过大量研究已经证实了EZH2的致癌活性。在细胞系实验中,过量表达EZH2会诱导细胞侵袭、在软琼脂中生长和运动,而敲低EZH2会抑制细胞增殖和细胞侵袭(Kleer等人,2003,《美国国家科学院院刊(Proc.Nat.Acad.Sci.USA)》100:11606-11611;Varambally等人,(2002),“polycomb组蛋白EZH2参与前列腺癌的进展(The polycomb group proteinEZH2 is involved in progression of prostate cancer),”《自然(Nature)》419,624-629)。已经表明,EZH2抑制几种肿瘤抑制因子的表达,包括E钙粘蛋白、DAB2IP和RUNX3以及其他。在异种移植模型中,EZH2敲除抑制肿瘤生长和转移。最近,已经表明在小鼠模型中下调EZH2阻断前列腺癌转移(Min等人,“癌基因肿瘤抑制因子级联通过协同激活Ras和核因子κB驱动转移性前列腺癌(An oncogene-tumor suppressor cascade drives metastaticprostate cancer by coordinately activating Ras and nuclear factor-kappaB)”NatMed.2010年3月;16(3):286-94)。EZH2过表达与某些癌症如乳腺癌的侵袭性有关(Kleer等人,《美国国家科学院院刊》100:11606-11611,2003)。最近的研究还表明,前列腺癌特异性致癌融合基因TMPRSS2-ERG通过直接激活EZH2诱导抑制性表观遗传程序(Yu等人,“前列腺癌进展中雄激素受体、Polycomb和TMPRSS2-ERG基因融合的整合网络(An IntegratedNetwork of Androgen Receptor,Polycomb,and TMPRSS2-ERG Gene Fusions inProstate Cancer Progression)”《癌症细胞(Cancer Cell)》.2010年5月,18;17(5):443-454)。

具体实施方式
定义
如本文所使用的,“结晶”是指化合物的固体形式,其中在原子的位置中存在长程原子顺序。固体的结晶性质可以例如通过检查X射线粉末衍射图来确认。
除非另有说明,否则化合物1的结晶形式(结晶形式1、结晶形式2和结晶形式3)均为单晶形式。“单晶形式”是指所述化合物,即化合物1,以单晶或多个晶体的形式存在,其中每个晶体具有相同的晶体形式(例如,形式1、2或3)。特定晶体形式的重量百分比是由特定晶体形式的重量除以特定晶体的总重量,加上存在的其他晶体形式的重量加上存在的无定形形式的重量乘以100%确定的。
“形式1”、“结晶形式1”或“单晶形式1”可互换使用。“形式2”、“结晶形式2”或“单晶形式2”可互换使用。“形式3”、“结晶形式3”或“单晶形式3”可互换使用。
化学纯度是指所公开的形式不含具有不同化学结构的材料的程度。所公开的晶体形式中化合物的化学纯度是指化合物的重量除以化合物的重量加上具有不同化学结构的材料/杂质的总和乘以100%,即重量百分比。
术语“无定形”是指以非结晶状态或形式存在的固体。无定形固体是无序的分子排列,并且因此不具有可区分的晶格或晶胞并且因此不具有可定义的长程排序。固体的固态排序可以通过本领域已知的标准技术来确定,例如,通过X-射线粉末衍射(XRPD)或差示扫描量热法(DSC)来确定。
术语“无水的”和“无水化合物”可互换使用,并且表示所提及的结晶形式在晶格中基本上没有水,例如,如通过Karl Fisher分析测定的小于1重量%。
用于本文所描述的结晶形式的X射线粉末衍射图的2-θ值可以因仪器不同而略微变化并且还根据在样品制备时的变化以及由于如温度变化、样品放置和存在或不存在内部标准等因素造成的批次间变化而略微变化。因此,除非另有定义,否则本文陈述的XRPD图/分配不应被解释为绝对的并且可以变化±0.2°。这种可变性将解释上述因素而不妨碍对晶体形式的明确鉴定在本领域是众所周知的。除非另有说明,否则本文提供的2θ值是使用CuKα1辐射获得的。
例如用于本文的DSC峰的温度值可以因仪器不同而略微变化并且还根据在样品制备时的变化、批次间变化和环境因素而略微变化。因此,除非另有定义,否则本文所陈述的温度值不应被解释为绝对的并且可以变化±5°或±2°。
“基本上相同的XRPD图”或“与……基本上相似的X射线粉末衍射图”意指为出于比较的目的,存在至少90%的所示的峰。应进一步理解,出于比较的目的,允许在峰值强度中存在与所示的那些的一些可变性,如±0.2°。
样品中一种结晶形式相对于另一种结晶形式的量可以通过制备一系列具有已知重量比的两种结晶形式的混合物并获得每种结晶形式的XRPD光谱来评估。例如,样品中结晶形式1和结晶形式2的相对量可以通过分别选择图1和图3中描绘的结晶形式1和结晶形式2的一个或多个特征峰,并将它们在样品XRPD中的相对强度与其在混合物XRPD中的相对强度相关联来评估。
如本文所使用的,术语“受试者”和“患者”可以互换使用,并且意指需要治疗的哺乳动物,例如,伴侣动物(例如,狗、猫等)、农场动物(例如,牛、猪、马、绵羊、山羊等)和实验室动物(例如,大鼠、小鼠、豚鼠等)。通常,受试者是需要治疗的人。
术语“药学上可接受的载体”是指无毒的载体、佐剂或媒介物,其不会不利地影响与其一起配制的化合物的药理学活性,并且其对人类使用也是安全的。可以用于本公开的组合物的药学上可接受的载体、佐剂或赋形剂包括但不限于离子交换剂、氧化铝、硬脂酸铝、硬脂酸镁、卵磷脂、血清蛋白诸如人血清白蛋白、缓冲物质诸如磷酸盐、甘氨酸、山梨酸、山梨酸钾、饱和植物脂肪酸的偏甘油酯混合物、水、盐或电解质诸如如硫酸鱼精蛋白、磷酸氢二钠、磷酸二钙、磷酸氢钾、氯化钠、锌盐、胶体二氧化硅、三硅酸镁、聚乙烯吡咯烷酮、聚乙烯吡咯烷酮-乙酸乙烯酯、基于纤维素的物质(例如微晶纤维素、羟丙基甲基纤维素、羟丙基甲基纤维素乙酸酯琥珀酸酯、羟丙基甲基纤维素邻苯二甲酸酯)、淀粉、乳糖一水合物、甘露醇、十二烷基硫酸钠和交联羧甲基纤维素钠、聚乙二醇、羧甲基纤维素钠、聚丙烯酸酯、聚甲基丙烯酸酯、蜡、聚乙二醇-聚氧丙烯-嵌段聚合物、聚乙二醇和羊毛脂肪。
术语“治疗(treatment/treat/treating)”是指逆转、减轻、减少发展的可能性或抑制如本文所述的疾病或病状或其一种或多种症状的进展。在一些实施例中,可以在发展到一种或多种症状后施用治疗,也就是说,治疗性治疗。在其它实施方案中,治疗可在不存在症状的情况下施用。例如,可以在症状发作之前(例如,根据症状历史和/或根据遗传或其它易感因素)向易感个体施用治疗,也就是说,预防性治疗。还可以在症状消退后继续治疗,例如以预防或延缓其复发。
术语“有效量”或“治疗有效量”包括本文所述的将引发受试者的生物学或医学应答的化合物的量,例如化合物1的剂量为0.001-100mg/kg体重/天。

1.仪器和方法细节
X射线粉末衍射(XRPD):
在Bruker AXS C2 GADDS、Bruker AXS D8 Advance或PANalytical Empyrean上采集了XRPD衍射图,如下面详细描述的。
Bruker AXS C2 GADDS
使用Cu Kα辐射(40kV,40mA)、自动XYZ载物台、用于自动样品定位的激光视频显微镜和二维区域探测器,使用Bruker AXS C2 GADDS衍射仪进行XRPD。X射线光学器件由单个多层反射镜和0.3mm的针孔准直器组成。光束发散度,即X射线束在样品上的有效尺寸,为约4mm。采用θ-θ连续扫描模式,其中样品-检测器距离为20cm,其给出1.5°–32.5°的有效2θ范围。通常,将样品暴露于X射线束持续120秒。用于数据收集和分析的软件分别是用于Win7/XP的GADDS和Diffrac Plus EVA。在环境条件下运作的样品是使用未经研磨按原样的粉末制备成平板试样。在载玻片或玻璃料上制备和分析样品。将样品轻轻压到载玻片上,以获得用于分析的平坦表面。在轻真空下过滤之前,通过向玻璃料中直接加入少量悬浮液,使用玻璃料过滤块从悬浮液中分离和分析固体。对于可变温度(VT)实验,将样品在环境条件下安装在Anton Paar DHS 900热台上。然后将样品以10℃/分钟加热至合适的温度,随后在数据收集开始前恒温保持1分钟。样品在环境条件下以使用按原样的散剂所得的平板试样形式运作。

2.一般结晶方法
用于结晶的筛选方法在下述方法中概述。
熟化/浆料熟化
在熟化室中:将用于熟化的悬浮液置于平台摇床培养箱(Heidolph Titramax/培养箱1000,图2)中,并且经受从环境温度到约50℃的一系列热冷循环。这是通过每4小时打开或关闭加热来实现的。始终保持摇晃。
在Polar Bear中:悬浮液在Polar Bear(剑桥反应器设计(Cambridge ReactorDesign))中在50℃下搅拌(500rpm)不同的时间长度。然后样品以0.1℃/分钟冷却至25℃,并且搅拌另外的四小时。此后,将样品以0.1℃/分钟加热回到50℃。然后重复所述循环。
冷却结晶
将溶液在Polar Bear中以0.1℃/分钟冷却至5℃,并在此温度下搅拌不同的时间长度。过滤所有的固体并在抽吸下干燥10分钟,并通过XRPD进行初步分析。将溶液进一步冷却至-20℃持续16小时,然后如前所述处理所有新固体。蒸发所有剩余的溶液(参见下文方法3)。
受控的蒸发
通过移除小瓶的盖子或通过将针头插入小瓶的隔膜帽,使放置在小瓶中的溶液在环境条件下蒸发。允许样品缓慢蒸发至干燥,或者直到在环境条件下出现固体。
通过添加反溶剂进行沉淀/结晶
将溶液在50℃下用反溶剂逐滴处理,直到其变得浑浊。然后将样品以0.1℃/分钟冷却至5℃,并保持恒温。在需要时,向悬浮液中加入额外的反溶剂。过滤固体并在抽吸下干燥10分钟,并且残留物最初由XRPD分析。
3.筛选方法
在室温下,将具有不同纯度的无定形形式的化合物1样品,一种纯度95.2%(30mg)并且另一种纯度97.6%(20mg)的样品,各自悬浮或溶解在10-30体积的给定溶剂中。在室温下平衡5分钟后,将所有样品(溶液和悬浮液)加热至50℃持续10分钟,并且所得的样品如下处理:悬浮液在60℃至5℃下熟化72小时(在每个温度下4小时)。将溶液以0.1℃/分钟从50℃冷却至5℃,并在5℃下保持72小时。如果未获得固体,则允许溶液在室温下蒸发。通过XRPD分析了所有回收的固体,随后通过适当的技术进行分析。对于筛选程序和分析结果,参见表1-3。
基于XRPD分析,使用纯度为95.2%的无定形形式的化合物1的多结晶形式物筛选产生三种结晶形式,在此被表示为形式1、形式2和形式3(表1和2)。形式1是最丰富的形式,其从多种溶剂体系中获得。从溶剂2-丁醇中仅观察到一次形式3。使用纯度为97.6%的无定形形式的化合物1的多结晶形式物筛选产生了形式1和形式2,但没有产生形式3(表3)。形式1比形式2更丰富。形式1-3的特征如下所示。

选择形式1和2用于进一步分析,因为形式3的XRPD显示出差的结晶相。对于形式1,从丙酮获得的样品具有最高的纯度(97.4%),并且仅包含痕量溶剂。如下所述,相应地对形式1进行放大实验。对于形式2,从MEK获得的样品具有更高的纯度(97.2%),并且仅包含少量残留的MEK。如下所述,相应地对形式1进行放大实验。
结晶形式1和形式2的放大
丙酮中的形式1和MEK中的形式2的放大实验均根据以下程序进行。按照U.S.62/659,408(1g)中的方法制备的化合物1的无定形形式被称入两个20ml闪烁小瓶中,并在50℃下在搅拌下溶解在20体积(20ml)的丙酮或20体积(20ml)的MEK中。然后将溶液以0.1℃/分钟冷却至5℃,并在此温度下保持20小时。两个样品均形成白色悬浮液,将悬浮液过滤并在真空下在布氏漏斗中干燥。在使用多种技术(总结在表4和5以及图1-4中)表征两种模式之前,将固体风干一小时。还根据回收的固体计算了产率。
对于形式1的放大,固体样品通过XRPD被确认为结晶形式1(表4和图1)。通过HPLC测定纯度为96.6%。通过1H NMR,样品与无定形形式的化合物1参考材料匹配,其中在样品中残留有少量残余丙酮(0.04当量)。热分析显示1.0%w/w(其相当于0.32当量的水)的重量损失,这与KF数据一致。DSC分析显示,在179.5℃(开始)时出现急剧吸热(图2)。GVS分析发现,材料具有轻微的吸湿性,在0到90%RH之间吸收1.7%w/w的水。GVS分析后,样品仍为形式1,或在升高的RH条件下储存5天。通过PLM和SEM的形式1的形态为小结晶颗粒的聚集体。这些聚集体的大小和形状可以变化(在20μm与650μm之间),并且结晶颗粒小且不规则(高达20μm)。总体上,确定形式1为无水的。对于形式1的属性汇总,还参见表5。
对于形式2的放大,固体样品通过XRPD证实为结晶形式2(图3)。然而,进一步的表征表明,形式2是比形式1更不稳定的结晶形式。例如,与保留其原始结晶形式的形式1不同,XRPD分析显示,形式2在GVS分析后变成无定形,或者在升高的RH条件下储存5天。不同于表现出急剧吸热的形式1(图2),形式2在DSC分析中表现出两个吸热事件(图4)。在TGA分析中,形式2也显示出比形式1更高的总重量损失。在多结晶形式物筛选期间和在竞争性浆料实验中,形式1比形式2更频繁被观察到,进一步确证了形式1比形式2更稳定。
