Definitions
- the present invention relates to a class of tricyclic macrocyclic compounds and their applications, specifically to the compounds represented by formula (II) and their pharmaceutically acceptable salts.
- kinases are related to cell proliferation, metabolism, differentiation and apoptosis. Abnormal activation of multiple kinases can lead to the occurrence of cancer.
- Anaplastic lymphoma kinase is a receptor tyrosine kinase (Receptor Tyrosine Kinase, RTK), which belongs to the insulin receptor (insulin receptor) family. It is mainly expressed in the central and peripheral nervous systems and plays a role in the development and function of the nervous system.
- ALK was originally discovered in a type of anaplastic large-cell lymphoma (ALCL).
- ACL anaplastic large-cell lymphoma
- the N-terminus of the normally expressed protein nuclear phosphate NPM is fused with the ALK kinase domain to form the fusion protein NPM-ALK.
- Chromosomal translocation leads to continued cell activation and ultimately the formation of tumors.
- ALK fusion proteins have been identified. Among them, EML4-ALK fusion protein is found in 3-7% of NSCLC patients and is considered a powerful factor that drives tumors. Therefore, EML4-ALK has been established as an effective target for cancer treatment.
- ALK inhibitors have entered clinical trials and been approved for marketing. Among them, Crizotinib and Lorlatinib have been approved by the FDA for the treatment of patients with ALK-positive NSCLC.
- Crizotinib and Lorlatinib have been approved by the FDA for the treatment of patients with ALK-positive NSCLC.
- ALK inhibitors have been proven effective in initial clinical trials, patients after treatment will develop ALK acquired resistance and brain metastasis (metastatic brain cancer).
- ALK mutations EML4-ALK-L1196M, EML4-ALK-L1198F, EML4-ALK-G1202R, EML4-ALK-G1202R-L1198F and EML4-ALK-G1202R-L1196M, etc. are the main reasons for the current ALK resistance mechanism.

本发明涉及一类含三并环的大环类化合物及其应用,具体涉及式(II)所示化合物及其药学上可接受的盐。
激酶(kinase)与细胞的增值、代谢、分化和凋亡相关,多种激酶的异常激活会导致癌症的发生。
间变性淋巴瘤激酶(Anaplastic lymphoma kinase,ALK)是一种受体酪氨酸激酶(Receptor Tyrosine Kinase,RTK),隶属于胰岛素受体(insulin receptor)家族。主要表达于中枢和周边神经系统中,在神经系统的发育和功能中发挥作用。
ALK最初是在一类渐变性大细胞淋巴瘤(anaplastic large-cell lymphoma,ALCL)中发现的。正常表达的蛋白核磷酸NPM的N端与ALK激酶结构域发生融合形成融合蛋白NPM-ALK,染色体易位导致细胞持续活化,最终形成肿瘤。目前,多种ALK融合蛋白已经被鉴定。其中,EML4-ALK融合蛋白在3-7%的NSCLC病人中发现,被认为是驱动肿瘤的强效因子,因此EML4-ALK被确立为可有效治疗癌症的靶点。
目前已经有多种ALK抑制剂进入临床试验并被批准上市。其中,Crizotinib(克唑替尼)和Lorlatinib(劳拉替尼)已被FDA批准用于治疗ALK阳性的NSCLC患者。遗憾的是,虽然ALK抑制剂在最初的临床中被证实有效,但经治疗后的患者会出现ALK获得性耐药和脑转移(metastatic brain cancer)。ALK的突变(EML4-ALK-L1196M,EML4-ALK-L1198F,EML4-ALK-G1202R,EML4-ALK-G1202R-L1198F和EML4-ALK-G1202R-L1196M等)是现阶段ALK耐药机制的主要原因。
因此,对于NSCLC患者的治疗,迫切需要可以克服现有ALK抑制剂获得性耐药的新一代抑制剂。

定义和说明
除非另有说明,本文所用的下列术语和短语旨在具有下列含义。一个特定的术语或短语在没有特别定义的情况下不应该被认为是不确定的或不清楚的,而应该按照普通的含义去理解。当本文中出现商品名时,意在指代其对应的商品或其活性成分。
这里所采用的术语“药学上可接受的”,是针对那些化合物、材料、组合物和/或剂型而言,它们在可靠的医学判断的范围之内,适用于与人类和动物的组织接触使用,而没有过多的毒性、刺激性、过敏性反应或其它问题或并发症,与合理的利益/风险比相称。
术语“药学上可接受的盐”是指本发明化合物的盐,由本发明发现的具有特定取代基的化合物与相对无毒的酸或碱制备。当本发明的化合物中含有相对酸性的功能团时,可以通过在纯的溶液或合适的惰性溶剂中用足够量的碱与这类化合物接触的方式获得碱加成盐。当本发明的化合物中含有相对碱性的官能团时,可以通过在纯的溶液或合适的惰性溶剂中用足够量的酸与这类化合物接触的方式获得酸加成盐。本发明的某些特定的化合物含有碱性和酸性的官能团,从而可以被转换成任一碱或酸加成盐。
本发明的药学上可接受的盐可由含有酸根或碱基的母体化合物通过常规化学方法合成。一般情况下,这样的盐的制备方法是:在水或有机溶剂或两者的混合物中,经由游离酸或碱形式的这些化合物与化学计量的适当的碱或酸反应来制备。
本发明的化合物可以存在特定的几何或立体异构体形式。本发明设想所有的这类化合物,包括顺式和反式异构体、(-)-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,例如对映异构体或非对映体富集的混合物,所有这些混合物都属于本发明的范围之内。烷基等取代基中可存在另外的不对称碳原子。所有这些异构体以及它们的混合物,均包括在本发明的范围之内。
除非另有说明,用楔形实线键和楔形虚线键表示一个立体中心的绝对构型,用直形实线键和直形虚线键表示立体中心的相对构型,用波浪线表示楔形实线键或楔形虚线键或两种异构体的混合物,或用波浪线表示直形实线键或直形虚线键或两种异构体的混合物。
除非另有说明,当化合物中存在双键结构,如碳碳双键、碳氮双键和氮氮双键,且双键上的各个原子均连接有两个不同的取代基时(包含氮原子的双键中,氮原子上的一对孤对电子视为其连接的一个取代基),如果该化合物中双键上的原子与其取代基之间用表示,则表示该化合物的(Z)型异构体、(E)型异构体或两种异构体的混合物。
除非另有说明,术语“富含一种异构体”、“异构体富集”、“富含一种对映体”或者“对映体富集”指其中一种异构体或对映体的含量小于100%,并且,该异构体或对映体的含量大于等于60%,或者大于等于70%,或者大于等于80%,或者大于等于90%,或者大于等于95%,或者大于等于96%,或者大于等于97%,或者大于等于98%,或者大于等于99%,或者大于等于99.5%,或者大于等于99.6%,或者大于等于99.7%,或者大于等于99.8%,或者大于等于99.9%。
除非另有说明,术语“异构体过量”或“对映体过量”指两种异构体或两种对映体相对百分数之间的差值。例如,其中一种异构体或对映体的含量为90%,另一种异构体或对映体的含量为10%,则异构体或对映体过量(ee值)为80%。
可以通过的手性合成或手性试剂或者其他常规技术制备光学活性的(R)-和(S)-异构体以及D和L异构体。如果想得到本发明某化合物的一种对映体,可以通过不对称合成或者具有手性助剂的衍生作用来制备,其中将所得非对映体混合物分离,并且辅助基团裂开以提供纯的所需对映异构体。或者,当分子中含有碱性官能团(如氨基)或酸性官能团(如羧基)时,与适当的光学活性的酸或碱形成非对映异构体的盐,然后通过本领域所公知的常规方法进行非对映异构体拆分,然后回收得到纯的对映体。此外,对映异构体和非对映异构体的分离通常是通过使用色谱法完成的,所述色谱法采用手性固定相,并任选地与化学衍生法相结合(例如由胺生成氨基甲酸盐)。
本发明的化合物可以在一个或多个构成该化合物的原子上包含非天然比例的原子同位素。例如,可用放射性同位素标记化合物,比如氚(3H),碘-125(125I)或C-14(14C)。又例如,可用重氢取代氢形成氘代药物,氘与碳构成的键比普通氢与碳构成的键更坚固,相比于未氘化药物,氘代药物有降低毒副作用、增加药物稳定性、增强疗效、延长药物生物半衰期等优势。本发明的化合物的所有同位素组成的变换,无论放射性与否,都包括在本发明的范围之内。
术语“任选”或“任选地”指的是随后描述的事件或状况可能但不是必需出现的,并且该描述包括其中所述事件或状况发生的情况以及所述事件或状况不发生的情况。
术语“被取代的”是指特定原子上的任意一个或多个氢原子被取代基取代,取代基可以包括重氢和氢的变体,只要特定原子的价态是正常的并且取代后的化合物是稳定的。当取代基为氧(即=O)时,意味着两个氢原子被取代。当取代基为=CH2时,意味着两个氢原子被取代。
术语“任选被取代的”是指可以被取代,也可以不被取代,除非另有规定,取代基的种类和数目在化学上可以实现的基础上可以是任意的。
当任何变量(例如R)在化合物的组成或结构中出现一次以上时,其在每一种情况下的定义都是独立的。因此,例如,如果一个基团被0-2个R所取代,则所述基团可以任选地至多被两个R所取代,并且每种情况下的R都有独立的选项。此外,取代基和/或其变体的组合只有在这样的组合会产生稳定的化合物的情况下才是被允许的。
当一个连接基团的数量为0时,比如-(CRR)0-,表示该连接基团为单键。
当一个取代基数量为0时,表示该取代基是不存在的,比如-A-(R)0表示该结构实际上是-A。
当一个取代基为空缺时,表示该取代基是不存在的,比如A-X中X为空缺时表示该结构实际上是A。
当其中一个变量选自单键时,表示其连接的两个基团直接相连,比如A-L-Z中L代表单键时表示该结构实际上是A-Z。
当所列举的连接基团没有指明其连接方向,其连接方向是任意的,例如,中连接基团L为-M-W-,此时-M-W-既可以按与从左往右的读取顺序相同的方向连接环A和环B构成也可以按照与从左往右的读取顺序相反的方向连接环A和环B构成所述连接基团、取代基和/或其变体的组合只有在这样的组合会产生稳定的化合物的情况下才是被允许的。
除非另有规定,当某一基团具有一个或多个可连接位点时,该基团的任意一个或多个位点可以通过化学键与其他基团相连。当该化学键的连接方式是不定位的,且可连接位点存在H原子时,则连接化学键时,该位点的H原子的个数会随所连接化学键的个数而对应减少变成相应价数的基团。所述位点与其他基团连接的化学键可以用直形实线键直形虚线键或波浪线表示。例如-OCH3中的直形实线键表示通过该基团中的氧原子与其他基团相连;中的直形虚线键表示通过该基团中的氮原子的两端与其他基团相连;中的波浪线表示通过该苯基基团中的1和2位碳原子与其他基团相连;表示该哌啶基上的任意可连接位点可以通过1个化学键与其他基团相连,至少包括
这4种连接方式,即使-N-上画出了H原子,但是仍包括这种连接方式的基团,只是在连接1个化学键时,该位点的H会对应减少1个变成相应的一价哌啶基。
除非另有规定,环上原子的数目通常被定义为环的元数,例如,“5-7元环”是指环绕排列5-7个原子的“环”。
除非另有规定,术语“卤代素”或“卤素”本身或作为另一取代基的一部分表示氟、氯、溴或碘原子。
