Definitions

  • This application relates to a class of tetracyclic compounds as Cdc7 inhibitors, and specifically discloses the compound represented by formula (I), its isomers or pharmaceutically acceptable salts thereof.
  • Cdc7 is a serine/threonine kinase, which was first discovered in Saccharomyces cerevisiae in 1974. Since then, scientists have also discovered homologous proteins in other eukaryotes. Different species of Cdc7 have certain differences in structure, but their functions are very similar. On the one hand, they phosphorylate the microchromosome maintenance protein (MCM protein), an important element of the DNA replication initiator, to activate MCM promotion. The formation of the replication initiation complex, on the other hand, can also be used as an important regulatory factor for the S phase checkpoint of the cell cycle to control the smooth progress of the cell cycle.
  • MCM protein microchromosome maintenance protein
  • huCdc7 The homologous protein of Cdc7 in human cells, huCdc7, was discovered by scientists after the 1990s. huCdc7 is expressed in almost all tissue cells in humans, but it has been found that huCdc7 is abnormally highly expressed in a variety of human tumor cells. This abnormally high expression is related to abnormal tumor proliferation, metastasis, and resistance to chemotherapy drugs. Both show high correlation, so huCdc7 has become an important marker and target for current tumor research.
  • huCdc7 The expression level of huCdc7 in the normal cell cycle is unchanged, and is regulated by some factors and accessory proteins in the cell cycle, so it is in a state of dynamic equilibrium. In tumor cells, due to cell cycle disorders, huCdc7 is in a state of abnormal expression and over-activation. Research by Hess et al. showed that because huCdc7 is over-expressed in a variety of tumor cells, over-expression of huCdc7 can promote the over-activation of MCM2, an important tumor cell marker, and thus promote the abnormal proliferation of tumor cells.
  • huCdc7 also showed high expression in all metastatic tumor cells, which also suggested that the abnormally high expression of huCdc7 may be closely related to tumor cell metastasis.
  • Nambiar et al. recently found that huCdc7 accessory protein ASK is also highly expressed in multiple skin melanoma cell lines, which further enhances the activity of huCdc7 in tumor cells.
  • the abnormally high expression and activation of huCdc7 also play a key role in tumor cell chemotherapeutic drug resistance.
  • Tenca et al. treated tumor cells with the chemotherapeutic drugs Hu and etoposide and found that huCdc7 was highly expressed and highly active. The study pointed out that huCdc7 It is through phosphorylation of multiple amino acid sites of MCM2 and MCM4 to inhibit their activities and reduce the damage of tumor cells.

技术领域
本申请涉及一类作为Cdc7抑制剂的四并环类化合物,具体公开了式(I)所示化合物、其异构体或其药学上可接受的盐。
背景技术
Cdc7是丝氨酸/苏氨酸激酶,其最早于1974年在酿酒酵母中发现,此后科学家们在其他真核生物里也发现了与其同源的蛋白质。不同物种的Cdc7在结构上都存在着一定差异,但它们之间的功能却极其相似,一方面是通过磷酸化DNA复制起始物一个重要元件微染色体维持蛋白(MCM蛋白),从而激活MCM促进复制起始复合物的形成,另一方面也可作为细胞周期S期检验点的重要调控因子来控制细胞周期的顺利进行。
人类细胞里Cdc7的同源蛋白——huCdc7是20世纪90年代后科学家们才发现的。huCdc7在人类几乎所有的组织细胞中均有表达,但人们发现,在人类多种肿瘤细胞里huCdc7均出现异常高表达,这种异常高表达与肿瘤的异常增殖、转移以及抗化疗药物性之间都显示出很高的相关性,因此huCdc7也就成为了目前肿瘤研究的重要标记和靶点。
huCdc7在正常细胞周期中表达水平是不变的,并且受到细胞周期中一些因子和辅助蛋白调控,因此处于一种动态平衡状态。在肿瘤细胞里由于细胞周期发生紊乱,huCdc7是处于异常表达和过度激活状态。Hess等研究表明,由于huCdc7在多种肿瘤细胞里过表达,过表达的huCdc7可促进肿瘤细胞的重要标记MCM2的过度活化,因而促进了肿瘤细胞的异常增殖。同时,他们还发现huCdc7在所有转移肿瘤细胞里也都显示出高表达,这也提示huCdc7的异常高表达与肿瘤细胞的转移可能有密切的联系。Nambiar等最近发现在多个皮肤黑色素瘤细胞系里huCdc7辅助蛋白ASK也是呈高表达状态,这也进一步增强huCdc7在肿瘤细胞里的活性。此外,huCdc7的异常高表达和激活对肿瘤细胞化疗药物抗性也起到很关键的作用,Tenca等用化疗药物Hu和etoposide处理肿瘤细胞后发现huCdc7大量表达并具有很高的活性,研究指出huCdc7是通过磷酸化MCM2和MCM4的多个氨基酸位点来抑制二者活性从而减少肿瘤细胞受到的损伤。
TAK-931是一种Cdc7抑制剂,目前已经处在临床二期因此研制新一代代谢稳定的Cdc7抑制剂,在临床上有需求。

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”是指本申请化合物的盐,由本申请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。当本申请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。药学上可接受的碱加成盐包括钠、钾、钙、铵、有机胺或镁盐或类似的盐。当本申请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。药学上可接受的酸加成盐的实例包括无机酸盐,所述无机酸包括例如盐酸、氢溴酸、硝酸、碳酸,碳酸氢根,磷酸、磷酸一氢根、磷酸二氢根、硫酸、硫酸氢根、氢碘酸、亚磷酸等;以及有机酸盐,所述有机酸包括如乙酸、丙酸、异丁酸、马来酸、丙二酸、苯甲酸、琥珀酸、辛二酸、反丁烯二酸、乳酸、扁桃酸、邻苯二甲酸、苯磺酸、对甲苯磺酸、柠檬酸、酒石酸和甲磺酸等类似的酸;还包括氨基酸(如精氨酸等)的盐,以及如葡糖醛酸等有机酸的盐本申请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。
本申请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。
本申请的药学上可接受的盐可以利用本身已知的方法或其类似的方法,将其转变为游离态;例如将药学上可接受的酸加成盐或碱加成盐与化学剂量的适当的碱或酸反应制备。
本申请的化合物可以存在特定的几何或立体异构体形式。本申请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申请的范围之内。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,均包括在本申请的范围之内。
本申请带“*”碳原子可为手性碳原子,意指根据该碳原子在化合物结构中的连接情况,其为手性碳原子或者非手性碳原子。
除非另有说明,术语“对映异构体”或者“旋光异构体”是指互为镜像关系的立体异构体。
除非另有说明,术语“顺反异构体”或者“几何异构体”系由因双键或者成环碳原子单键不能自由旋转而引起。
除非另有说明,术语“非对映异构体”是指分子具有两个或多个手性中心,并且分子间为非镜像的关系的立体异构体。

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%。
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。如果想得到本申请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)。本申请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。本申请的化合物的所有同位素组成的变换,无论放射性与否,都包括在本申请的范围之内。
当本文所述化合物含有烯属双键或其它几何不对称中心,除非另有规定,它们包括E、Z几何异构体。同样地,所有的互变异构形式均包含在本申请范围之内,例如

三者为互变异构形式。
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,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。氧取代不会发生在芳香基上。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。

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

化合物的抑瘤疗效用TGI(%)或相对肿瘤增殖率T/C(%)评价。相对肿瘤增殖率T/C(%)=TRTV/CRTV×100%(TRTV:治疗组RTV;CRTV:阴性对照组RTV)。根据肿瘤测量的结果计算出相对肿瘤体积(relative tumor volume,RTV),计算公式为RTV=Vt/V0,其中V0是分组时(即D0)测量所得平均肿瘤体积,Vt为某一次测量时的平均肿瘤体积,TRTV与CRTV取同一天数据。
TGI(%),反映肿瘤生长抑制率。TGI(%)=[(1-(某处理组给药结束时平均瘤体积-该处理组开始给药时平均瘤体积))/(溶媒对照组治疗结束时平均瘤体积-溶媒对照组开始治疗时平均瘤体积)]×100%。
