Abstract

本发明涉及具有AXL抑制活性的取代吡嗪化合物或其药学上可接受的盐、其药物组合物及其用途,所述化合物可以用于治疗由AXL激酶功能亢进引起、与AXL激酶功能亢进相关和/或伴随AXL激酶功能亢进的病症。

Description

具有AXL抑制活性的取代吡嗪化合物 技术领域
本发明属于药物领域,具体地,涉及一种具有AXL抑制活性的取代吡嗪化合物、其药学上可接受的盐及其药物组合物。本发明还涉及使用该化合物和组合物治疗与AXL活性相关的疾病和疾病状态。
背景技术
AXL(也称为UFO、ARK和Tyro7或JTK11),是受体酪氨酸激酶(RTKs)中的TAM家族成员之一。AXL最初被鉴定为一种在慢性髓性白血病或慢性骨髓增生性疾病患者细胞中表达的转化基因。据报道,AXL过度表达与多种癌症有关,包括非小细胞肺癌(NSCLC)、乳腺癌、前列腺癌、胃癌、肾细胞癌和胶质母细胞瘤。AXL的激活为细胞增殖、存活、迁移、侵袭和血管生成提供了强有力的信号。此外,AXL已越来越多地被认为是对许多已批准的酪氨酸激酶抑制剂疗法产生耐药性的关键介质。因此,AXL可以作为癌症治疗的潜在靶点。
为了满足目前临床上对治疗癌症、免疫系统疾病和循环系统疾病的药物需要,达到更好的治疗效果,设计与研究开发AXL激酶抑制剂,寻找高效低毒的具有临床应用前景的化合物,对于医药领域具有重大的意义。

相关定义
除非特别指明,本说明书和所附权利要求中所用的下列术语具有所指明的含义:
如本文使用的和除非另作说明,术语“包含”,“包括”,“具有”,“含有”,包括其语法上的等同形式,通常应当理解为开放式且非限制性的,例如,不排除其他未列举的要素或步骤。
本发明“化合物”可以是不对称的,例如,具有一个或多个手性中心。除非另有说明,本发明的“化合物”可以是任意一种异构体或两种以上的异构体的混合物。本发明的“化合物”包括所述化合物的异构体(如立体异构体)、对映体、非对映体、外消旋物或两种以上异构体的混合物。
术语“异构体”是指具有相同分子式、但原子排列和构型不同的不同化合物。“对映体”是互为不可叠加镜像的一对立体异构体。一对对映体的1:1混合物是“外消旋”混合物。在适宜的情况下,该术语用于指外消旋混合物。“非对映异构体”是具有至少两个不对称原子、但是不互为镜像的立体异构体。绝对立体化学是根据Cahn-lngold-Prelog R-S系统来规定的。当一种化合物是纯对映体时,每个手性碳上的立体化学可以用R或S来说明。拆分的其绝对构型不明的化合物可以根据它们在钠D线波长下旋转平面偏振光的方向(右旋-或左旋-)或在手性色谱法分离时的保留时间而被指定为(+)或(-)。本文所述的一些化合物含有一个或多个不对称中心或轴,因此可以产生对映体、非对映体和可以在绝对立体化学上被定义为(R)-或(S)-或者用(+)或(-)符号表示的其它立体异构形式。本发明包括所有这类可能的异构体,包括外消旋混合物、旋光纯的形式和中间混合物。旋光活性的(R)-和(S)-异构体可以用手性合成子或手性试剂制备或者用常规技术进行拆分。如果化合物含有双键,则取代基可以是E或Z构型。如果化合物含有二取代的环烃基,则环烃基取代基可具有顺式-或反式-构型。即,本发明的化合物包括但不限于顺式和反式异构体、(-)-和(+)-对映体、(R)-和(S)-对映体,非对映异构体、(D)-异构体、(L)-异构体、及其外消旋混合物和其他混合物。本发明的含有不对称碳原子的化合物可以以光学活性纯的形式或两种以上的异构体的混合物的形式被分离得到。光学活性纯的形式可以从两种以上的异构体的混合物中进行拆分,或通过使用手性原料或手性试剂合成。
本发明“化合物”还包括互变异构体形式。互变异构体形式来源于一个单键与相邻的双键交换并一起伴随一个质子的迁移。术语“互变异构体”或“互变异构体形式”是指在室温下,不同官能团异构体处于动态平衡,并能很快的相互转化。
本领域技术人员可以以已知的方式将可根据本发明得到的异构体混合物分离成单个异构体;非对映异构体可以例如通过在多相溶剂混合物之间分配、重结晶和/或色谱分离例如硅胶色谱分离或通过例如使用反相柱的中压液相色谱法来分离,外消旋物可以例如通过与光学纯的成盐试剂形成盐并分离(例如利用分级结晶分离)可如此获得的非对映异构体混合物或者通过在旋光活性柱材料上进行色谱处理来分离。可以按照标准方法、例如使用色谱法、分配法、(重)结晶等对中间体和终产物进行后处理和/或纯化。在所有的反应阶段,形成的异构体混合物可以被分离成单个异构体,例如非对映异构体或对映体,或者被分离成任意所需的异构体混合物,例如外消旋物或非对映异构体混合物。
酌情为本发明的实施方案提供绝对立体化学和/或旋光度。本发明关注本文所提供的化合物的所有立体化学形式。在一些情况中,化合物含有两个或更多个手性中心。这些化合物的相对立体化学是通过NMR研究和/或X-射线衍射鉴定的。在一些情况中,未测定非对映体对的相对立体化学,因此当仅一种异构体被分离和/或可获得时,根据在所给出的HPLC条件下的保留时间来标示/区分对映体。相同样品通常具有同样的保留时间,但可能存在一定操作误差,当由本领域普通技术人员,采用相应方法得到的样品采用相同的仪器和检测方法进行检测时,保留时间误 差通常在±0.2min以内,优选在±0.1min以内;不同技术人员使用不同仪器可能偶然出现少数保留时间的误差超出该范围,如误差在±0.5min以内;或±0.3min以内;或±0.2min以内均应认为属于相同的物质,因此保留时间误差在±0.5min、±0.3min、±0.2min或±0.1min以内的都可被解释为本发明保护范围之内。
本发明中,用表示一个立体中心的绝对构型。
本发明的化合物可以通过本领域技术人员所熟知的常规方法来确认结构,如果本发明涉及化合物的绝对构型,则绝对构型可以通过本领域常规技术手段予以确证。例如单晶X射线衍射法(SARD)。
