Description

R228060 盐酸盐的晶型及其制备方法和用途 技术领域
本发明涉及药物晶体技术领域。具体而言,涉及R228060盐酸盐的晶型及其制备方法和用途,属于医药领域。
背景技术
白天睡眠过多(Excessive Daytime Sleepiness,EDS)或病理性嗜睡指与各种睡眠和清醒病症相关的白天睡眠过多。这些病症可以是基础睡眠病症或者对睡眠有副作用的一些其它医学病症所致。白天睡眠过多,又称为嗜睡症,是睡眠诊所中所见的主要患者疾病,其影响占普通人群的12%。EDS患者可能会表现为精神苦恼、工作或学习表现欠佳,增加了发生事故的风险,EDS的影响可使人衰弱,甚至威胁生命。
R228060,又名JZP-110,是一种选择性多巴胺和去甲肾上腺素再摄取抑制剂,最初由韩国SK生物制药公司研发,2014年爵士制药获得该化合物的所有权。R228060具有治疗嗜睡症和睡眠呼吸暂停综合症的潜力,在两项全球多中心3期研究中均达到了主要研究终点,取得了积极的效果,显着的改善了成人阻塞性睡眠呼吸暂停患者的过度嗜睡和嗜睡症患者过度睡眠问题。
R228060化学名称为O-氨基甲酰基-(D)-苯丙氨醇,其结构式如式(I)所示:

固体化学药物晶型不同,可造成其溶解度和稳定性不同,从而影响药物的吸收和生物利用度,并且会导致临床药效的差异。通过成盐方式提高候选化合物的溶解度已成为药物研发中的重要手段。与药物的游离形式相比,适宜的药物盐型能提高药物的溶解度,增加物理化学稳定性,而且药物成盐后还可改善其熔点、吸湿性、结晶类型等物理性质,对进一步开发药物剂型具有重要作用。专利文献WO1996007637A1中公开了R228060盐酸盐及其制备方法,并得到了一种熔点为172-174℃白色固体,文本中未给出该固体的其他特征数据。此外,本申请发明人未发现其他有关R228060盐酸盐的晶型专利或文献报道。因此, 本领域需要系统全面的开发R228060盐酸盐的晶型,以发现适合开发的晶型。本申请发明人经过了大量的实验研究,发现了R228060盐酸盐的晶型CS1和晶型CS2,晶型CS1和晶型CS2的熔点为183℃,熔点远高于现有技术公开的固体。为含R228060的药物制剂的制备提供了更好的选择,对于药物开发具有非常重要的意义。

本发明中,“晶体”或“多晶型”指的是被所示的X射线衍射图表征所证实的。本领域技术人员能够理解,这里所讨论的理化性质可以被表征,其中的实验误差取决于仪器的条件、样品的准备和样品的纯度。特别是,本领域技术人员公知,X射线衍射图通常会随着仪器的条件而有所改变。特别需要指出的是,X射线衍射图的相对强度也可能随着实验条件的变化而变化,所以峰强度的顺序不能作为唯一或决定性因素。事实上,XRPD图谱中衍射峰的相对强度与晶体的择优取向有关,本文所示的峰强度为说明性而非用于绝对比较。另外,峰角度的实验误差通常在5%或更少,这些角度的误差也应该被考虑进去,通常允许有±0.2°的误差。另外,由于样品高度等实验因素的影响,会造成峰角度的整体偏移,通常允许一定的偏移。因而,本领域技术人员可以理解的是,本发明中一个晶型的X射线衍射图不必和这里所指的例子中的X射线衍射图完全一致,本文所述“XRPD图相同”并非指绝对相同,相同峰位置可相差±0.2°且峰强度允许一定可变性。任何具有和这些图谱中的特征峰相同或相似的图的晶型均属于本发明的范畴之内。本领域技术人员能够将本发明所列的图谱和一个未知晶型的图谱相比较,以证实这两组图谱反映的是相同还是不同的晶型。
在一些实施方案中,本发明的晶型CS1和晶型CS2是纯的、单一的,基本没有混合任何其他晶型。本发明中,“基本没有”当用来指新晶型时指这个晶型含有少于20%(重量)的其他晶型,尤其指少于10%(重量)的其他晶型,更指少于5%(重量)的其他晶型,更指少于1%(重量)的其他晶型。
需要说明的是,本发明中提及的数值及数值范围不应被狭隘地理解为数值或数值范围本身,本领域技术人员应当理解其可以根据具体技术环境的不同,在不背离本发明精神和原则的基础上围绕具体数值有所浮动,本发明中,这种本领域技术人员可预见的浮动范围多以术语“约”来表示。
此外,本发明提供一种药物组合物,所述药物组合物包含治疗和/或预防有效量的本发明晶型CS1、晶型CS2,以及至少一种药学上可接受的载体、稀释剂或赋形剂。
进一步的,本发明提供R228060盐酸盐的晶型CS1、晶型CS2在制备治疗中枢神经系统疾病药物制剂中的用途。
进一步的,本发明提供R228060盐酸盐的晶型CS1、晶型CS2在制备治疗嗜睡症和睡眠呼吸暂停综合症药物制剂中的用途。
本发明晶型CS1和晶型CS2的有益效果:
1)本发明的晶型CS1和晶型CS2具有较好的稳定性,包含高温稳定性、长期稳定性和机械稳定性。晶型CS1和晶型CS2的熔点均在183℃附近,远高于现有专利中的固体(172-174℃)的熔点,具有更好的高温稳定性。晶型CS1和晶型CS2在25℃/60%RH或/ 和40℃/75%RH至少可稳定放置一个月,优选的至少可稳定放置六个月,优选的至少可稳定放置一年。晶型CS1和晶型CS2具有较好的稳定性,能够保证药品在制备、运输、贮藏及保存过程中不会发生转晶现象而影响到药品质量,对保证药物疗效和安全性,防止药物不良反应的发生具有重要意义。将晶型CS1和晶型CS2手动研磨30分钟,晶型和结晶度均未发生明显变化,说明本发明晶型CS1和晶型CS2具有突出的机械稳定性,制剂加工过程中常需要原料药的研磨粉碎,高的机械稳定性能够减小制剂加工过程中发生原料药晶型结晶度改变和转晶的风险。
2)本发明提供的晶型CS1和晶型CS2具有优异的溶解性和较高的溶出速率,在水中的溶解度大于10mg/mL,晶型制备成胶囊制剂后,在水中10min时的溶出量即可达60%以上。在制剂开发中,药物具有快速的溶出速率可加快药物服用后在体内快速溶解,可通过调整辅料,控制药物在特定部位快速发挥作用,提高药物的起效速率。
3)本发明提供的晶型CS1和晶型CS2几乎无引湿性,80%相对湿度下增重分别为0.12%和0.08%,且引湿性前后晶型未发生改变。几乎无引湿性的晶型在制剂过程中可不必控制环境湿度,对包装和贮存条件无特殊苛刻要求,节约成本,易于工业化生产和药品的长期贮存。由于对储存条件要求不苛刻,将大大降低物料储存以及质量控制成本,具有很强的经济价值,更适合药用。
4)本发明提供的晶型CS1和晶型CS2具有良好的制剂稳定性,晶型在制剂中至少可稳定放置两周。放置一段时间晶型和单杂含量均未发生明显变化,对保证制剂安全和疗效具有重要意义。

关于引湿性特征描述与引湿性增重的界定(中国药典2015年版通则9103药物引湿性试验指导原则,实验条件:25℃±1℃,80%相对湿度):
引湿性特征描述与引湿性增重的界定:
潮解:吸收足量水分形成液体。
极具引湿性:引湿增重不小于15%。
有引湿性:引湿增重小于15%但不小于2%。
略有引湿性:引湿增重小于2%但不小于0.2%。

硬脂酸镁 6
将获得的胶囊测试溶出情况,溶出度的测定按照中国药典2015年版0931溶出度与释 放度测定法,条件如下:
溶出介质:水
溶出方法:浆法
介质体积:500mL
转速:50rpm
介质温度:37℃
晶型CS1和晶型CS2的溶出速率结果表明晶型CS1和晶型CS2均具有较快的溶出速率,10min时的溶出量即可达60%以上。在制剂开发中,药物具有快速的溶出速率可加快药物服用后在体内快速溶解,可通过调整辅料,来控制药物在特定部位快速发挥作用,提高药物的起效速率。
上述实施例只为说明本发明的技术构思及特点,其目的在于让熟悉此项技术的人士能够了解本发明的内容并据以实施,并不能以此限制本发明的保护范围。凡根据本发明精神实质所作的等效变化或修饰,都应涵盖在本发明的保护范围之内。
