Abstract
式(I)的HCV大环抑制剂钠盐的无定形形式以及制备该盐的方法。
Description
本申请为分案申请,原申请的申请日为2010年2月26日,申请号为201080009908.9(PCT/EP2010/001197),发明名称为“HCV大环抑制剂的无定形盐”。
发明领域
本发明涉及无定形形式的HCV大环抑制剂钠盐以及制备该无定形钠盐的方法。
发明背景
丙型肝炎病毒(HCV)感染通常被认为是世界范围内一个重大的医疗保健问题。HCV感染可发展为肝纤维化,后者可导致肝硬化,末期肝病和HCC(肝细胞癌),这使其成为肝移植的主要原因。现行HCV治疗护理标准涉及在24周或28周期间联合给予聚乙二醇化干扰素-α-2a或聚乙二醇化干扰素-α-2b与利巴韦林(ribavirin)。现行疗法的局限在于仅有部分患者治疗成功,而且该疗法面临显著的副作用,通常耐受性差且持续时间长。因此,需要克服这些缺点的HCV抑制剂。
HCV基因组的复制由许多酶介导,其中之一为HCV NS3丝氨酸蛋白酶。已经描述了抑制该酶的各种试剂。WO 05/073216公开了带有中心环戊烷部分的线状和大环NS3丝氨酸蛋白酶抑制剂。WO2007/014926公开了一系列大环NS3丝氨酸蛋白酶抑制剂,包括这些化合物的盐形式。在它们当中,具有下述化学结构的式I化合物是特别引人注意的。该化合物的化学全名为(1R,4R,6S,15R,17R)-cis-N-[17-[2-(4-异丙基噻唑-2-基)-7-甲氧基-8-甲基喹啉-4-基氧基]-13-甲基-2,14-二氧代-3,13-二氮杂三环[13.3.0.04,6]十八-7-烯-4-羰基](环丙基)磺酰胺或(1R,4R,6S,7Z,15R,17R)-N-[17-[2-(4-异丙基噻唑-2-基)-7-甲氧基-8-甲基喹啉-4-基氧基]-13-甲基-2,14-二氧代-3,13-二氮杂三环[13.3.0.04,6]十八-7-烯-4-羰基](环丙基)磺酰胺,也称为″TMC435″。TMC435可通过WO 2007/014926实施例5描述的合成步骤制备。本文所用术语“式I化合物”和″TMC435″是指同一化学实体。
TMC435不仅针对HCV表现显著活性,还具有吸引人的药代动力学概况。临床研究表明该化合物在患者体内有良好耐受性,并证实其有效抑制HCV的潜能。
TMC435的水溶性差,提高其溶解度以及其伴随的生物利用度是药物开发的理想目标。给予较高剂量的水溶性差的药物可克服生物利用度的问题,但是这导致产生更大且因此更不可行的剂型。紧密且易于制造是理想的剂型。
已知水溶性差的活性剂的生物利用度可通过将其转化成无定形形式而提高。通常,药剂结晶程度越高,其生物利用度就越低,反之亦然,降低结晶度对生物利用度有积极影响。无定形材料通常表现出令人感兴趣的性质如比结晶形式更好的溶解速率和溶解度,通常导致生物利用度提高。生成和稳定这种状态通常证明是困难的,因为许多物质的无定形形式是不稳定的,部分或全部迅速转化成更加稳定的结晶形式。该转化受到外界因素如温度、湿度、环境中痕量结晶材料等的影响。有时由于暂未清楚的原因,似乎长时间稳定的无定形甚至可部分或全部转化成结晶形式。
无定形和结晶形式不仅在生物利用度方面表现出差异,还在其加工性质方面表现出差异,如吸湿性、流动性、紧密性等。如果在固体剂型的临床开发和制造期间,药品的固体形式不稳定,则使用或研究的理想形式的确切量可因批次不同而异,这不仅造成治疗功效的不需要的差异性,还导致制造条件的不需要的差异性。因此,由于结晶形式在药物剂型制造和储存中的稳定性,进入开发的药物几乎总是被转化成其结晶形式。因此很少药物以无定形状态被利用。
本发明的一个目标是提供式I化合物的固体形式,其具有稳定性以及一种或多种以下的有利性质:其生物利用度、药物代谢动力学性质例如释放率、曲线下面积等;以及其配制、储存和以有效发挥其抗病毒性给药的能力。
现已发现式I化合物的钠盐可转化成其无定形形式,该形式意想不到地稳定并且可有利地用作抗HCV治疗的活性成分。该形式可转化成紧密且易于制造的药物组合物和剂型。还发现该形式可方便地通过喷雾干燥制造步骤而制备。

发明详述
本发明涉及无定形形式的式I化合物的钠盐。本发明还涉及制备式I化合物钠盐的无定形形式的方法。
在一个实施方案中,本发明涉及如本文所述基本不含杂质的无定形形式的式I化合物钠盐。在一个具体的实施方案中,无定形形式的式I化合物钠盐包含不超过约5%的杂质,或不超过约2%的杂质,或不超过约1%的杂质,或不超过约0.5%杂质,或不超过约0.1%的杂质。杂质可为除式I化合物外的化合物,或可为式I化合物的任何其它固体形式,特别是结晶形式。纯度可通过标准的光谱技术测定,如用X射线衍射。
本发明还涉及制备无定形形式的式I化合物钠盐的方法,所述方法包括如下步骤:
a)在药学上可接受的非水溶剂和水性氢氧化钠中制备式I化合物的混合物;以及
b)在喷雾干燥装置中喷雾干燥步骤a)的混合物。
在一个实施方案中,步骤a)包括将氢氧化钠溶液与所述溶剂混合,随后加入式I化合物,优选以其游离形式,即非盐形式。在一个具体的实施方案中,将氢氧化钠水溶液加入到所述溶剂中,随后加入式I化合物。步骤a)的程序优选在搅拌下进行。还优选的是在步骤a)中使式I化合物形成溶液,随后将该溶液喷雾干燥。
步骤a)所得的混合物或溶液然后通过喷雾干燥器的喷嘴喷雾化,借此所得小滴的溶剂通常在高温下蒸发,例如通过引入热气。
在一个实施方案中,水性氢氧化钠是氢氧化钠在水性介质中(特别地为水中)的浓溶液,例如NaOH溶液的范围为约1N-约12.5N,或约5N-12.5约N,或约7.5N-约12.5N,例如为约10N。
可用于此过程的溶剂是那些可接受用于药物组合物的制备并且具有足够用于喷雾干燥的挥发性(沸点低于例如150℃,或低于例如100℃)且可充分溶解TMC435(TMC435的溶解度例如>10g/l,或例如>50g/l)的溶剂。适宜的溶剂包括卤代烃,例如氯仿优选为二氯甲烷;或醚例如二乙醚或四氢呋喃。
干燥气体可为任何气体。优选地,气体为空气或惰性气体例如氮气,富氮空气或氩气。喷雾干燥室进气孔干燥气体的温度可为约25℃-约300℃,或约60℃-约300℃,或约60℃-约150℃。
喷雾干燥在常规的喷雾干燥装置进行,该装置包括喷雾干燥室、用于将进料混合物以小滴形式引入喷雾干燥室的雾化工具、通过入口流入喷雾干燥室的热干燥气体源和热干燥气体出口。该喷雾干燥装置还包括用于收集产生的固体药物粉末的工具。雾化工具可为旋转雾化器、气动喷嘴、超声喷嘴或优选的高压喷嘴。
适宜的旋转雾化器包括具有由高压压缩空气源运作的空气涡轮传动装置(air turbine drive)的旋转雾化器,例如6巴压缩空气源,其提供动力给雾化轮用以雾化进料混合物。雾化轮可为叶轮。优选地,旋转雾化器位于喷雾干燥室的上部,如在室顶,从而使得产生的小滴干燥且落入到室的下部。通常,旋转雾化器产生的小滴大小范围为约20-约225μm,特别地为约40-约120μm,小滴大小取决于轮圆周速度。
适宜的气动喷嘴(包括双流体喷嘴)包含位于喷雾干燥室的上部例如在室顶的气动喷嘴,并以所谓的“并流模式”运行。用压缩空气进行雾化使得气液比的范围为约0.5-1.0∶1至约5∶1,特别地为约1∶1至约3∶1。进料混合物和雾化气体分别通过雾化发生的喷嘴头。通过气动喷嘴产生小滴的大小取决于操作参数,范围可为例如约5-125μm,或约20-50μm。
可使用以所谓的“逆流模式”运行的双流体喷嘴。这些喷嘴与并流模式双流体喷嘴运行的方式相似,区别在于其位于干燥室的下部并且是向上喷雾化小滴。通常,当逆流双流体喷嘴生成的小滴干燥时,产生约15-约80μm大小范围的颗粒。
适宜的超声雾化喷嘴将低粘度液体转化为超微细喷雾。随着液体通过探头的中心泵出,该液体从振动端被机械雾碎成小滴。探头频率越低,这些小滴则越大,探头频率越高,小滴则越小。
用于本发明的优选雾化器类型是高压喷嘴,其中液体进料在压力下被泵至喷嘴。压力能转换成动能,,进料作为因不稳定而迅速分解成喷雾的高速薄膜从喷嘴孔喷出。用漩涡插件(swirl insert)或漩涡室使进料在喷嘴内旋转,致使从喷嘴孔以锥形喷洒方式射出。漩涡插件、漩涡室和孔径与压力变化一起控制进料速率和喷雾特性。高压喷嘴产生的小滴的大小取决于操作参数且范围可为约5-125mm,例如约20-约50mm。
适宜的雾化工具可根据所需小滴大小而选择,这取决于许多因素,例如进料混合物的粘度和温度、所需流速和泵送进料混合物的最大可接受压力,其影响小滴大小。选择雾化工具从而获得针对特定粘度进料混合物的所需平均小滴大小后,将混合物以特定的流速导入到喷雾干燥室。
可将喷雾干燥步骤后获得的粉末进一步干燥,例如在高温或低压或两者结合下。
本文所述方法提供了制备非常高产率和高纯度(两者都接近100%,例如产率为>95%,或>99%,百分比在纯度的情况下为w/w,即重量/重量)的TMC435无定形钠盐的合宜步骤。干燥后,少量水可存在于所得产物中,例如约5%-约1%,w/w。当接触湿气时,可吸收多达13%(特别地约13.1%)。即使吸收了水分,产物仍保持稳定。
在加入所需赋形剂之后,所得粉末可直接加工成固体剂型例如片剂或胶囊剂。

实施例
以下实施例意在说明本发明而非限制本发明。
实施例1:无定形形式TMC435钠盐的制备
将氢氧化钠10N溶液(通过在55.80g的净化水中溶解24.00g氢氧化钠来制备)加入5949.00g剧烈搅拌的二氯甲烷。在温和搅拌下,将TMC435(450.00g)加入该混合物,持续搅拌直至所得混合物可见澄清。在N2条件下将由此所得的混合物于标准的喷雾干燥器中喷雾干燥。收集喷雾干燥的产物并于真空烘箱中干燥。所得粉末即为TMC435无定形钠盐,含有971.53mg/g粉末量的有效成分TMC435的游离形式。
实施例2:TMC435口服胶囊的制备
将实施例1所得的喷雾干燥粉末(72.05g)、月桂基硫酸钠(1.19g)、无水胶体二氧化硅(1.19g)和乳糖一水合物(158.83g)过筛并在合适的容器中共混10分钟。将过筛的硬脂酸镁(1.19g)加入该混合物中并将所得混合物再共混5分钟。将所得组合物填充到硬明胶胶囊中。
表1表示在制备无定形TMC435钠盐口服胶囊中用于典型批量大小的700粒胶囊的批量配方
表2表示在制备无定形TMC435钠盐25mg口服胶囊中用于典型批量大小的600粒胶囊的批量配方
实施例3:按照实施例1制备的无定形钠盐的表征
●无定形
●在192.5℃表现出玻璃化转变
●包含溶剂(水)
-DSC在81.1℃(78J/g)显示吸热信号
-TGA显示重量损失3.7%(25-245℃)
●吸湿性的
红外光谱术(IR)
微衰减全反射(微ATR)
用适宜的微ATR辅助设备分析样品
TMC435钠盐的红外光谱含有溶剂(水),反映TMC435钠盐分子结构的振动模式。
红外光谱见图1
粉末XRD
在带有发生器PW3040的Philips X’PertPRO MPD衍射仪PW3050/60上进行X-射线粉末衍射(XRPD)分析。该仪器配备CuLFF X-射线管PW3373/10。将所述化合物涂到零本底的样品架上。
仪器参数
测量条件
无定形TMC435钠盐的X射线粉末衍射图显示只存在晕,表明该化合物以无定形产物存在。
XRD图见图2
差示扫描量热法(DSC)
将约3mg的化合物转移到标准的铝TA-Instrument样品盘(samplepan)。该样品盘用盖盖上,在配备RCS冷却单元的TA-InstrumentsQ1000MTDSC上记录DSC曲线。
参数
由于溶剂蒸发,TMC435钠盐的DSC曲线在81.1℃(77J/g)时显示出吸热信号。
在±199.4℃下观察第二事件,其很可能与玻璃化转变(Tg)、松弛能和/或溶剂蒸发有关。
DSC曲线参见图3
调制差示扫描量热法(MDSC)
将约3mg的无定形TMC435钠盐转移到标准的铝TA-Instrument样品盘。该样品盘用盖盖上,在配备RCS冷却单元的TA-Instruments Q1000MTDSC上记录DSC曲线。
参数
进行MDSC实验以确定样品的玻璃态转化(Tg)(比热转变)。一般而言,MDSC实验可从热容(逆向热流信号)变化分离出溶剂的蒸发和松弛能,其为动力过程(非逆向热流信号)。(总)热流可与标准的DSC信号相比。如果非密封样品盘用于无定形TMC435钠盐,则MDSC曲线显示,在±46.9℃下存在的溶剂蒸发与在±192.5℃下的玻璃态转化清楚地分离。
MDSC叠加见图4.
热重量分析法(TGA)
将无定形TMC435转移到铝TA-Instrument样品盘。在TA-Instruments Q500热解重量分析器上记录TG曲线。
参数
对于无定形TMC435钠盐,由于存在于样品中的溶剂(水)的蒸发,在从室温直到245℃的温度区域内,记录到重量损失±3.7%。高于250℃下的重量损失是由于产物的分解。
TGA曲线见图5
吸附-脱附(DVS)
将无定形TMC435(19mg)转移到SMS(Surface MeasurementSystems Ltd.)动态湿气吸附模型DVS-1,在25℃大气湿度下记录重量变化。
参数
干燥: 干氮气下60min
平衡: ≤0.01%/min(最少15min,最多60min)
数据间隔: 0.05%或2.0min
在如下相对湿度(RH(%))水平进行测定:
第一组:5,10,20,30,40,50,60,70,80,90,95,90,80,70,60,50,40,30,20,10,5
第二组:5,10,20,30,40,50,60,70,80,90,95,90,80,70,60,50,40,30,20,10,5,0
在起始干燥步骤期间,记录到化合物I钠盐重量损失为2.03%。所得干燥产物是吸湿性的且在高相对湿度下吸附多达13.1%的水。在脱附循环期间,产物仍保留1.61%的水分。
用IR和XRD研究在DVS后所得的产物,其仍为无定形。
ADS/DES曲线见图6。
