Description

1-氯-4-(β-D-吡喃葡萄糖-1-基)-2-[4-((S)-四氢呋喃-3-基氧基)-苄基]-苯的晶型、其制备方法及其用于制备药物的用途
本发明涉及1-氯-4-(β-D-吡喃葡萄糖-1-基)-2-[4-((S)-四氢呋喃-3-基氧基)-苄基]-苯的晶型、其制备方法,及其用于制备药物的用途。
发明背景
化合物1-氯-4-(β-D-吡喃葡萄糖-1-基)-2-[4-((S)-四氢呋喃-3-基氧基)-苄基]-苯(下文中指“化合物A”)描述在国际专利申请书WO 2005/092877中并具有如式A的化学结构:
Figure A20068001159100041
该文中描述的化合物对于钠-依赖性葡萄糖协同转运蛋白SGLT,具体地为SGLT2,具有有价值的抑制作用。化合物A的制造方法如该文中描述并不会产生晶型。
具体的药用活性是药物活性物质被批准上市必需满足的基本先决条件。然而,有多种其他的要求也是药物活性物质必须遵循的条件。这些要求以各种与其本身活性物质的性质有关的参数为基础。在没有限制下,这些参数的实例为活性剂在各种环境条件下的稳定性、在药物组合物制造期间的稳定性,以及活性剂在最终药物组合物的稳定性。用于制备药物组合物的药物活性物质应尽可能纯且必须保证在各种环境情况下具有长期保存的稳定性。避免使用含有除了含有确实活性物质外还含有例如其分解产物的药物组合物是最基本的。在这些情形下,药物中的活性物质含量可能少于标示的含量。
该药物在制剂中均匀分布为关键因素,特别是当药物必须以低剂量给予时。为了保证均匀分布,活性物质的颗粒大小利用例如磨碎而减少至适合大小。由于要尽可能避免药物活性物质因为磨碎(或微粉化)而造成分解的副作用,尽管在加工期间需要强烈的条件,活性物质在整个磨碎过程应为高度稳定是最基本的。唯有当活性物质在磨碎过程中足够稳定,才可能产生均匀的药物组合物,才能以可重复的方式含有标示量的活性物质。
在制备期望药物组合物的磨碎过程可能产生的另一个问题为由该过程引起的能量输入以及在晶体表面的压力。这在一些情下可能引起多晶型改变、无定性化或晶格改变。由于药物组合物的药物品质要求活性物质应该总是具有相同的晶型,因此由同样的观点看来,结晶活性物质的稳定性和性质应该满足严格的要求。
药物活性物质的稳定性在决定药物组合物中具体药物的保存期限也很重要;保存期限是指该药物可不会有任何危险给药的时间长短。因此上述药物组合物中的药物在各种储存条件下具有高稳定性对病人和制造商两者来说皆为额外的好处。
水分的吸收降低药物活性物质的含量,主要是因为水分的吸收会造成重量的增加。易于吸收水分的药物组合物在储存期间必须利用例如其他适用的干燥剂或利用将药物储存在防潮的环境中而加以保护以防潮湿。因此优选地,药物活性物质应只具有轻微吸湿性。
此外,明确晶型的可获性使得药物物质可利用重结晶的方式纯化。
除了上述所示的要求,一般应该牢记的是,对于固态药物组合物来说,能够改善其物理和化学稳定性的任何改变,对于较不稳定形式的相同药物能提供显著的优势。
因此本发明的目标在于提供化合物A的稳定晶型,其满足上述对于药物活性物质所提出的重要要求。

令人惊讶地,已经发现其中存在有化合物A的晶型,其可执行本文前述的重要需求。因此本发明涉及化合物A的晶型。
该晶型可通过其特征性X-射线粉末衍射(XRPD)谱图的方法而加以鉴定。
该晶型可通过由X-射线粉末衍射图表征,其含有在18.84、20.36和25.21度2θ(±0.05度2θ)的峰,其中所述X-射线粉末衍射图使用CuKα1辐射。
具体地,该X-射线粉末衍射图包含在14.69、18.84、19.16、19.50、20.36和25.21度2θ(±0.05度2θ)的峰,其中所述X-射线粉末衍射图可利用CuKα1辐射获得。
更具体地,该晶型通过X-射线粉末衍射图表征,使用CuKα1辐射,其包含如表1中所包含的度2θ(±0.05度2θ)的波峰。
表1:晶型的X-射线粉末衍射图(仅列出在2θ中低于30度的峰):

甚至更具体地,该晶型通过X-射线粉末衍射图而定出特征,CuKα1辐射,其在2θ(±0.05度2θ)包含如图1所示的峰。
此外,化合物A的晶型可通过由约149℃±3℃的熔点(通过DSC测定;以起始温度评估;加热速率10K/分钟)表征。得到的DSC曲线显示在图2中。
在本发明范围内,利用STOE-STADI P-衍射仪,以装置有位置敏感检测器(OED)和Cu-阳极作为X-射线源(CuKα1辐射,λ=1.54056,40kV,40mA)的传输模式,记录X-射线粉末衍射图。在表1中,上述“2θ[°]”值代表单位为度的衍射角度且“d[]”值代表在晶格平面之间的单位为的具体距离。图1显示强度单位为cps(每秒钟的次数)。
为了允许实验误差,上述2θ应考虑必须准确至±0.05度2θ。也就是说,当评估给定的化合物A的结晶样品是否为本发明的晶型时,经实验观察到样品的2θ值,如落在特征值的±0.05度2θ中,应认为与上述的特征值相同。
熔点可通过由差式扫描热量仪(Differential Scanning Calorimetry;DSC)利用DSC 821(Mettler Toledo)测定。
