Abstract
本发明涉及一种酪氨酸激酶抑制剂的二马来酸盐的I型结晶及制备方法。具体地,本发明涉及(R,E)-N-(4-(3-氯-4-(吡啶-2-基甲氧基)苯基氨基)-3-氰基-7-乙氧基喹啉-6-基)-3-(1-甲基吡咯烷基-2-基)丙烯酰胺二马来酸盐(简称SHR1258二马来酸盐)I型结晶及其制备方法和用途。所述制备方法包括将任意晶型或无定型的SHR1258二马来酸盐固体在单一的有机溶剂或者他们的混合有机溶剂中结晶得到SHR1258二马来酸盐I型结晶。本发明所得到SHR1258二马来酸盐I型结晶具备良好的晶型稳定性和化学稳定性,并且所用结晶溶剂低毒低残留,可更好地用于临床治疗。
Description
技术领域
本发明涉及一种酪氨酸激酶抑制剂的二马来酸盐的结晶形态,特别是(R,E)-N-(4-(3-氯-4-(吡啶-2-基甲氧基)苯基氨基)-3-氰基-7-乙氧基喹啉-6-基)-3-(1-甲基吡咯烷基-2-基)丙烯酰胺二马来酸盐的I型结晶及其制备方法和用途。
背景技术
近年来我国的肿瘤死亡率呈明显上升趋势,癌症严重威胁着人们的生命和生活质量,因此寻找高效、低毒的抗肿瘤药物是当今生命科学中极富挑战性且意义重大的课题。受体酪氨酸激酶是一类参与信号转导的跨膜蛋白,研究表明,超过50%的原癌基因和癌基因产物都具有酪氨酸激酶活性,它们的异常表达将导致肿瘤发生。酪氨酸激酶抑制剂从2001年开始上市,已成为异军突起的一类新型抗癌药。
表皮生长因子受体(EGFR)是受体酪氨酸激酶家族的一员,表皮生长因子受体通路在肿瘤发生、发展过程中起非常重要的作用,目前已成为肿瘤治疗领域最主要的研究和开发靶点之一。现已经上市的此类药物有埃罗替尼(erlotinib)、吉非替尼(gefitinib)和拉帕替尼(lapatinb,Tykerb,GW572016),目前尚处于临床阶段的有来那替尼(neratinib)。WO2011029265公开了化合物(R,E)-N-(4-(3-氯-4-(吡啶-2-基甲氧基)苯基氨基)-3-氰基-7-乙氧基喹啉-6-基)-3-(1-甲基吡咯烷基-2-基)丙烯酰胺(为表述方便,以下简称SHR1258)的制备方法,该药物分子具有明显的药代、药效优势。尽管WO2011029265中公开了化合物SHR1258的化学结构和制备方法,但未对其成盐的情况进行研究。在中国专利申请201110062359.8中描述了该化合物的二马来酸盐,(以下简称SHR1258二马来酸盐)结构如下:
但是却没有进一步研究SHR1258二马来酸盐的晶型以及制备方法。本领域技术人员知道,药用的活性成分的晶型结构往往影响到该药物的化学稳定性,结晶条件及储存条件的不同有可能导致化合物的晶型结构的变化,有时还会伴随着产生其他形态的晶型。一般来说,无定型的药物产品没有规则的晶型结构,往往具有其它缺陷,比如产物稳定性较差,析晶较细,过滤较难,易结块,流动性差等。因此,改善上述产物的各方面性质是很有必要的,我们需要深入研究找到晶型纯度较高并且具备良好化学稳定的新晶型。
发明内容
本发明的目的是提供一种SHR1258二马来酸盐的稳定晶型以及制备该晶型的方法。
我们考察了SHR1258二马来酸盐在不同结晶条件下得到的一系列结晶产物,对所得结晶产物进行了X-衍射及DSC检测,发现SHR1258二马来酸盐在常规的结晶条件下,可以得到一种稳定性良好的晶型,我们称其为I型结晶。本申请中的I型结晶的DSC图谱显示在130℃附近有熔融吸热峰,X-射线粉末衍射图谱如图1所示,使用Cu-Ka辐射,以2θ角度和晶面间距(d值)表示的X-射线粉末衍射图谱,其中在6.28(14.06),6.74(13.10),10.60(8.34),11.58(7.64),13.50(6.55),14.90(5.94),15.80(5.60),18.26(4.85),20.66(4.30),21.14(4.20),22.96(3.87),24.34(3.65),25.54(3.49)和26.12(3.41)有特征峰。
本发明制备I型结晶的方法中,可作为原料使用的SHR1258二马来酸盐的存在形态没有特别限定,可以使用任意晶型或无定型固体,本发明的SHR1258二马来酸盐I型结晶的制备方法为:
在用某些低级有机溶剂,优选含碳原子数小、同时能够挥发并可用作结晶溶剂的醇类、酮类、酯类等极性有机溶剂,或它们的混合溶液;更优选为异丙醇、丙酮、乙醇、乙酸乙酯、四氢呋喃或它们的混合物作为SHR1258二马来酸盐结晶的重结晶溶剂。析晶时可以用单一溶剂,也可以用选自以上有机溶剂的混合溶剂。
具体的,本发明提供的制备SHR1258二马来酸盐I型结晶的方法包括以下步骤:
(1)将SHR1258与马来酸,或者将SHR1258二马来酸盐固体溶解于适量的有机溶剂中,冷却析晶;
(2)过滤、洗涤、干燥。
在本发明优选的实施方案中,步骤(1)中,有机溶剂选自碳原子数小于等于3的醇类、丙酮、乙酸乙酯、四氢呋喃中的一种或几种。进一步优选有机溶剂选自乙醇、异丙醇、四氢呋喃中的一种或几种。
进一步地,最优选的单一溶剂为异丙醇。
在本发明的一个实施方案中,优选的混合有机溶剂为乙醇/四氢呋喃的混合溶剂,二者比例没有特别限制,在本发明优选的实施方案中,二者体积比为1:1。
重结晶的方法没有特别限定,可以用通常的重结晶操作方法进行。例如,可以用原料SHR1258二马来酸盐在有机溶剂加热溶解后慢慢冷却静置析晶,也可采取搅拌析晶,结晶完成后,经过滤干燥,即可得到所需要的结晶。需特别说明的是,SHR1258二马来酸盐形成稳定的晶型需要具备充分的转化过程,析晶时溶液的过度饱和往往导致析晶过程过快,容易得到无定型固体或晶型纯度较差的结晶,适当的增大溶剂体积或放慢析晶速度,则有助于得到晶型纯度较高的稳定晶型。所滤取的结晶体通常在减压下,在30~100℃左右,优选40~60℃的加热条件下进行真空干燥,就能达到去除重结晶溶剂的效果。
通过差示扫描热分析(DSC)、X-衍射图谱测定,对得到的SHR1258二马来酸盐结晶体进行了晶型研究,同时对所得结晶的溶剂残留进行了检测。
按照本发明的方法制备的SHR1258二马来酸盐结晶不含有或仅含有较低含量的残留溶剂,符合国家药典规定的有关医药产品残留溶剂的限量要求,因而本发明的结晶可以较好地作为医药活性成分使用。
经研究表明,本发明制备的SHR1258二马来酸盐I型结晶在高温、高湿的条件下稳定性显著好于无定型样品且在研磨、压力和受热等条件下,晶型稳定性良好,能够满足生产运输储存的药用要求,生产工艺稳定可重复可控,能够适应于工业化生产。
