替格瑞洛的一水合物及其制备方法与在制药中的应用 技术领域
本发明涉及药物,具体涉及药物水合物及其制备方法,尤其涉及一种小分子 抗凝剂替格瑞洛的一水合物及其制备方法与在制药中的应用。 背景技术
(IS, 2S, 3R, 5S) -3- [7- [ (1R, 2S) -2- (3, 4 -二氟苯基)环丙胺基]- 5- (丙硫 基) - 3H-[1, 2, 3]三唑 [4, 5-d]并嘧啶 - 3-基] -5- (2-羟乙氧基)环戊基 - 1, 2-二醇 (替格瑞洛, ticagrelor), CAS号为 274693- 27-5, 下列结构式所示:
Figure imgf000002_0001
替格瑞洛
替格瑞洛是美国阿斯利康 (AstraZeneca)公司研发的一种新型的、 具有选择 性的小分子抗凝血药。 该药能可逆地作用于血管平滑肌细胞 (VSMC)上的嘌呤 2 受体亚型 P2Y12,替格瑞洛不是前药,因此不需要代谢激活,对二磷酸腺苷(ADP) 引起的血小板聚集有明显的抑制作用,且口服使用后起效迅速,能有效改善急性 冠心病患者的症状。 与噻吩并吡啶类药物(氯吡格雷、普拉格雷等)不同, 替格 瑞洛对 P2Y12 ADP受体是可逆拮抗剂, 所以对于那些需在先期进行抗凝治疗后再 行手术的病人尤为适用。
阿斯利康公司的专利 W00192262 (以下简称 262' 专利) 公开了替格瑞洛的 四个晶型 (晶型 I, 晶型 II, 晶型 III, 晶型 IV)和无定形状态及其制备方法, 此四种晶型和无定形均是 "无水"状态。尽管在该专利中提到了溶剂化物和水合 物, 但是该专利的公开文本中对于相应的溶剂化物和水合物没有任何表征数据, 且没有任何实施例能够表明阿斯利康公司的专利 W00192262确实制备和公开了 一种或几种溶剂化物以及水合物。
专利 262' 专利公开的晶型 I, 需要通过繁复的温度控制方法获得, 以添加 晶种的方式制备晶型 I,溶剂中大量使用到水,但是却并不能获得水合物。 262' 专利公开的晶型 II的制备, 需要用到 I类的有毒有害溶剂氯仿, 对于工业化和 环境保护均是不利的,是难以实现工业化的; 262' 专利公开的晶型 III的制备, 是通过制备 II和 III晶型的混晶, 并以混晶为晶种制备晶型 III, 这样的操作 在工业上很难控制其晶体纯度,并且在后续的制备中,涉及异丙醇和水 1 : 1的溶 剂体系, 并且同样不能获得水合物; 晶型 IV的制备, 要用到有毒有害, 沸点较 低的乙腈, 同样是不利于环保和工业化生产的。
另外, 阿特维斯(ACTIVAS)公司的专利 W02013079589公开另一种替格瑞洛 的无水晶型及其制备方法。但是其制备方法复杂, 操作手续繁杂, 条件苛刻, 难 以控制, 专利说明书实施例 1甚至在 -70°C下滴加抗溶剂, 并且三种以上有机溶 剂的混合使用,使得溶剂难以回收套用,大大增加了生产成本和环境保护的压力, 这些都难以工业化生产。
许多化合物可以以不同晶型或多晶型物的形式存在, 它们具有不同的物理、 化学和光谱特性。例如, 同一化合物的某些晶型可能比其它晶型更易溶于特定溶 剂、 流动性更好, 或者可能更易于被压縮, 例如, Knapman, K. Morden Drug Discoveries, 2000, 53 ; Dimartino P.等, J. Thermal Anal. , 1997. 48 : 447-458。 对于药物而言,某些固体形式相比于其它形式更易于被生物利用, 同时在某些制 备、 储存和生物条件下可能更加稳定。 由于替格瑞洛是属于生物药剂分类系统 (BCS) IV类, 本发明人发现, 由于替格瑞洛在水中基本不溶, 因此替格瑞洛很 难制备形成水合物。利用现有技术, 根本无法制备出替格瑞洛的水合物, 往往得 到的都是粘稠的油状物, 因此, 为了提高其在水中的溶解度、溶解速率或者长期 存放的稳定性,研究开发一种宜于制备成药物制剂,又易于实现工业化的水合物 是关注的问题。 发明内容
本发明所要解决的技术问题在于克服上述不足之处,研宄设计具有较好稳定 性或者溶解性,适于工业化生产的替格瑞洛的一水合物晶型及其制备方法与在 制药中的应用。
本发明人通过对于结晶条件的大量研宄和仔细探索,惊奇地发现在以水为溶 剂的体系或者醇-水溶剂的体系中加入适量的 DMSO或 DMF, 经过静置析晶, 以较 小的溶剂体系和高收率获得纯的一水合物晶型。将此一水合物晶型作为晶种,通 过一水合物晶种的添加, 在有机溶剂 (所述的有机溶剂为醇、 DMS0、 DMF)和水 的混合溶剂中, 无需长时间混悬、静置、特别低的析晶温度或特别复杂的析晶工 艺, 就能够以较快的速度(析晶时间 1-12小时), 较高的收率(收率大于 80%), 较易工业化的制备方法, 制备获得替格瑞洛一水合物晶型。
本发明提供一种替格瑞洛一水合物晶型。
本发明所述替格瑞洛一水合物晶型的热重谱图显示在 5(TC至 140°C,其失重 率为 3%, 说明结构中含 1份结晶水(见附图 1 ); 其差热谱图 (DSC)显示, 在 102±5°C 以及 136± 5°C有两个较大的吸热峰(见附图 2) 。

根据这些结晶学数据证明: 替格瑞洛一水合物晶型属正交晶系, F222空间 群。晶体结构研宄表明,其最小对称单元中含有一个替格瑞洛分子和一个水分子, 分子间氢键 04- Η4···04'和 Ν6-Η6〜01" [Symmetric code: (i)- x, y, 1-z; (ii)-x, 2-y, z]将四个替格瑞洛分子连成一个圈, 形成一个空腔(空腔大小约为 230A3), 四个水分子就填在这个空腔中,水分子和替格瑞洛分子中的羟基形成氢键,此分 子圈沿 c方向无限延伸。 另两个分子间氢键作用 02- 112"*0 和 01-Η1···Ν6"" [Symmetric code: (iii)x, 1.5- y, 1.5- z; (iiii)- x, 2-y, z]将上述四个分子 组成的分子圈连接在一起, 沿 b方向堆叠, 形成三维空间无限堆叠图。 因此替格 瑞洛一水合物晶型中所包含的这个水分子具有较高的稳定性,也表明其为含水合 物晶型。 表 2 替格瑞洛一水合物晶型的晶系、 空间群和晶胞参数
