本发明涉及可用于制备诸如2-{乙基[3-({4-[(5-{2-[(3-氟苯基)氨基]-2-氧代乙基}-1H-吡唑-3-基)氨基]喹唑啉-7-基}氧基)丙基]氨基}乙基二氢磷酸酯(AZD1152)的药物化合物的新方法以及在所述方法中使用的中间体。
Description
本发明涉及可用于制备诸如2-{乙基[3-({4-[(5-{2-[(3-氟苯基)氨基]-2-氧代乙基}-1H-吡唑-3-基)氨基]喹唑啉-7-基}氧基)丙基]氨基}乙基二氢磷酸酯(本文称作AZD1152)的药物化合物的新方法,该化合物是极光激酶(aurora kinase)抑制剂,可用于治疗过度增殖疾病诸如癌。特别地,本发明涉及制备某些极光激酶抑制剂的磷酸酯前药形式的方法。本发明还涉及用于所述方法中的新型的中间体。
癌(和其它的过度增殖疾病)的特征在于当细胞增殖的正常调控丧失时发生的无控细胞增殖。这一丧失似乎通常是由对通过细胞周期控制细胞进程的细胞路径的基因损伤导致。
在真核生物中,认为蛋白质磷酸化的有序级联控制细胞周期。已经识别了在该级联中起决定性作用的若干个蛋白质激酶家族。这些激酶中有许多激酶在人肿瘤中的活性与正常组织中相比有所增加。这可通过蛋白质的表达水平增加(例如由于基因扩增所致)或通过在共同激活剂或者抑制蛋白质的表达的改变而发生。
这些细胞周期调节剂中第一个被识别的并被广泛地研究的是细胞周期蛋白依赖激酶(或CDK)。最近,已经识别出结构不同于CDK家族的蛋白质激酶并且发现其在细胞周期调节中起关键作用。这些激酶还似乎在肿瘤生成中很重要并且包括果蝇极光蛋白质(Drosophila aurora)和酿酒酵母(S.cerevisiae)Ipll蛋白质的人同系物。这些基因极光-A、极光-B和极光-C(还分别称作极光2、极光1和极光3)的这三种人的同系物编码细胞周期调节的丝氨酸-苏氨酸蛋白质激酶(在Adams等,2001,Trends inCell Biology.11(2):49-54中总结)。这些通过G2和有丝分裂表现表达和激酶活性的峰值。一些观测显示了人极光蛋白质涉及癌。极光-A基因定位于染色体20q13-在包括乳房肿瘤和结肠肿瘤的两种人肿瘤中通常被扩增的结构域。极光-A可能是该扩增子的主要靶基因,因为极光-A的DNA被扩增并且mRNA在原发性人结直癌中以大于50%被过度表达。在这些肿瘤中,极光-A蛋白水平显示大大高于相邻的正常组织。另外,使用人极光-A转染啮齿动物的成纤维细胞导致转变,赋予在软琼脂中生长的能力并在裸鼠中形成肿瘤。(Bischoff等,1998,The EMBO Journal.
17(11):3052-3065)。其它工作(Zhou等,1998,Nature Genetics.20(2):189-93)已表明极光-A的人工过度表达导致中心体数目增加并且以非整倍增加,这是在癌的发展过程中的已知事件。
还表明,当与正常细胞相比,在肿瘤细胞中,极光-B(Adams等,2001,Chromsoma.110(2):65-74)和极光-C(Kimura等,1999,Journal ofBiological Chemistry,274(11):7334-40)的表达增加。极光-B在癌细胞中的过度表达和极光-B的水平增加已经显示与结直肠癌的晚期有关(Katayama等,(1999)J.Natl.Cancer Inst.91:1160)。此外,一份报道显示,极光-B的过度表达通过在丝氨酸10处增加的组蛋白H3磷酸化作用而诱导非整倍性,并且过度表达极光-B的细胞形成更具攻击性的发展为转移性病灶的肿瘤(Ota,T.等,2002,Cancer Res.62:5168-5177)。极光-B是染色体过客蛋白,其与至少三种其它的过客蛋白Survivin、INCENP和Borealin存在于稳定的络合物中(Carmena M.等,2003,Nat.Rev.Mol.Cell Biol.4:842-854)。Survivin在癌中也被上调并且包含BIR(细胞程序死亡蛋白质(IAP)Repeat的杆状病毒抑制剂)结构域并因此可在保护肿瘤细胞免于细胞程序死亡和/或有丝分裂突变中发挥作用。
关于极光-C,其表达被认为只限于睾丸,但是已经在多种癌系中发现其被过度表达。(Katayama H等,2003,Cancer and Metastasis Reviews22:451-464)。
重要地是,还已证明了通过用反义寡核苷酸处理人肿瘤细胞系而消除极光-A的表达和作用(WO 97/22702和WO 99/37788)导致细胞周期停滞并且在这些肿瘤细胞系中发挥抗增殖作用。另外,极光-A和极光-B的小分子抑制剂已被证明在人肿瘤细胞中具有抗增殖作用(Keen等,2001,Poster #2455,American Association of Cancer Research annualmeeting),诸如通过siRNA治疗而选择性仅消除极光-B的表达(Ditchfield等,2003,journal of Cell Biology,161(2):267-280)。这显示了抑制极光-A和/或极光-B的作用将具有抗增殖作用,该作用可用于治疗人肿瘤和其它的过度增殖疾病。极光激酶被抑制作为这些疾病的治疗手段相对于以细胞周期上游的信号路径(例如通过生长因子受体酪氨酸激酶诸如表皮生长因子受体(EGFR)或其它受体被激活的那些路径)为靶标具有显著的优点。因为细胞周期是所有这些不同的信号事件的最终下游,针对细胞周期的疗法诸如抑制极光激酶被预测在所有的增殖性肿瘤细胞中都具有活性,而针对特异性信号分子(例如EGFR)的方法被预测仅仅在表达这些受体的肿瘤细胞亚类中具有活性。还据信在这些信号路径之间存在显著的“cross talk”,意味着一种组分被抑制可被其它所补偿。
在国际专利申请WO03/55491和WO2004/058781中描述了极光激酶的抑制剂,并且特别在WO2004/058781中公开了具有以下结构式(IA)的化合物,其在本文中被称作AZD1152:
AZD1152是前体药物,其(在人血浆中)迅速地和完全地转化为具有以下结构式(IVA)的活性部分,该活性部分在本文中被称作AZD1152HQPA:
AZD1152HQPA是极光激酶的ATP-竞争性和可逆性抑制剂,具有对抗极光A、B-INCENP和C-INCENP的强活性(Ki值分别是1369±419.2nM,0.359±0.386nM和17.03±12.2nM)。已经发现AZD1152在人结肠
直肠(SW620、HCT116、Colo205)和肺(A549、Calu-6)肿瘤异种移植清单中以统计显著性抑制肿瘤生长。
WO2004/058781公开了用于制备与AZD1152具有类似类型的化合物的一般工艺路线。WO2004/058781还公开了用于制备AZD1152的工艺路线。该工艺路线的概要如方案1所示。
本发明涉及用于制备AZD1152和相似化合物的改进方法。特别地,本发明涉及用于从AZD1152HQPA制备AZD1152的改进方法。该方法由于其与AZD1152特别相关,因此其概要如方案2所示。该方法不同于先前公开方法之处在于其包括了式(IIA)的新型中间体:
