Definitions

  • the invention belongs to the technical field of medicine, and specifically relates to a polo-like kinase 4 (hereinafter referred to as "PLK4") inhibitor compound and its use.
  • PLK4 polo-like kinase 4
  • Polo-like kinases are a class of highly conserved serine/threonine protein kinases, each of which has a highly homologous serine/threonine kinase domain at its N-terminus and a polo box at its C-terminus.
  • polo-box domain PPD
  • PLK1 PLK2, PLK3 and PLK4
  • Mouse PLK4 is located on chromosome 13 and is divided into two subtypes, a and b.
  • Human PLK4 is located on chromosome 4q28 and has only one PLK4 protein.
  • the whole process is 970 amino acid with high homology to mouse PLK4-a.
  • the amino acid sequence of PLK4 is quite different from other PLKs.
  • the PBDs of other PLKs have two polo boxes arranged in tandem, while PLK4 has only one polo box.
  • PLK4 was found to be mainly expressed in actively dividing tissues and cells, and the mRNA of PLK4 protein was expressed at the highest level in testis, and also expressed in tumor cell lines such as Hela, SKOV-3, Saos-2, A-431, etc. .
  • tumor cell lines such as Hela, SKOV-3, Saos-2, A-431, etc.
  • the mRNA level of PLK4 protein was not expressed in cells in G0 phase, increased at the end of G1 phase, and continued to rise in S and M phases; after the end of mitosis, it gradually decreased in early G1 phase. Studies have shown that this precise regulation is necessary to maintain the integrity of the nucleus as cells grow and divide.
  • PLK4 is one of the main regulators of centriole replication. During replication, its activation can promote the recruitment of tubulin to centrioles, thereby promoting the gradual maturation of centrioles. Habedanck 1 first found that overexpression of wild-type PLK4 can lead to an increase in the number of centrioles in cells, while insufficient expression of PLk4 can also lead to a decrease in the number of centrioles and abnormal centrosome structure in cells. In tumor cells, abnormalities in centrosome structure and number frequently occur, and the abnormalities are accompanied by cell division defects and genomic instability. It has been found that PLK4 is abnormally expressed in some tumor tissues and cell lines, and is regulated by P53, and may be involved in the occurrence and development of tumors. Therefore, PLK4 is a potential target for tumor targeted therapy.
  • PLK4 kinase inhibitor drug there is no PLK4 kinase inhibitor drug on the market.
  • CFI-400945 developed by The University Health Network is a selective PLK4 kinase inhibitor with good antitumor activity 2 , which is still in clinical trials. Therefore, developing novel PLK4 kinase inhibitors, enriching clinical drug types, and improving drug accessibility have important medical value and social significance.
  • the technical problem to be solved by the present invention is to provide a compound with novel structure and PLK4 kinase inhibitory activity. Further, the present invention provides a compound with novel structure and better pharmacodynamic activity of PLK4 kinase inhibitory activity.
  • the technical problems that can be solved by the present invention also include that the compounds of the present invention can be used to treat cancer diseases mediated by PLK4.

Description

PLK4抑制剂及其用途 技术领域
本发明属于医药技术领域,具体涉及polo样激酶4(以下简称“PLK4”)抑制剂化合物及其用途。
背景技术
Polo样激酶(polo-like kinases,PLKs)是一类高度保守的丝氨酸/苏氨酸蛋白激酶,其N端均有一个高度同源的丝氨酸/苏氨酸激酶结构域,其C端具有polo盒结构域(polo-box domain,PBD),该结构域可以调节PLKs激酶活性并与该蛋白的亚细胞动态定位有关。PLKs家族成员较多,其在人体内有4种亚型,分别是PLK1、PLK2、PLK3和PLK4,它们在细胞周期各个时相的调控中发挥至关重要的作用。
其中,PLK4于1994年被发现,其广泛存在于真核生物中,小鼠PLK4位于13号染色体,分为a、b两个亚型,人类PLK4位于染色体4q28,仅有一个PLK4蛋白,全程970个氨基酸,与小鼠PLK4-a具有高度同源性。PLK4的氨基酸序列与其它PLKs有较大差异,其它PLKs的PBD都有两个串联排列的polo盒,而PLK4只有一个polo盒。
研究发现,PLK4被发现主要在分裂活跃的组织和细胞中表达,PLK4蛋白的mRNA在睾丸中表达水平最高,在肿瘤细胞株如Hela、SKOV-3、Saos-2、A-431等中也有表达。在正常周期性循环的细胞中,PLK4蛋白的mRNA水平在G0期细胞中不表达、在G1期末期增加,并在S期和M期持续上升;有丝分裂结束后,在G1期早期逐渐下降。研究表明这种精确调控对于细胞生长和细胞分裂时维持细胞核的完整性是必要的。
PLK4是中心粒复制的主要调控因子之一,复制过程中,其激活后可促进微管蛋白向中心粒募集,从而促进中心粒逐渐成熟。Habedanck 1首先发现,过量表达野生型PLK4可导致细胞中心粒数目增加,而PLk4表达不足也可引起细胞内中心粒数目减少以及中心体结构异常。肿瘤细胞中,经常发生中心体结构和数目的异常,而异常伴随着细胞分裂缺陷和基因组不稳定。现已发现PLK4在部分肿瘤组织和细胞系中表达异常,并受到P53的调控,可能参与了肿瘤的发生、发展,因而PLK4是肿瘤靶向治疗的一个潜在靶点。
目前,尚无PLK4激酶抑制剂药物上市,其中The University Health Network研发的CFI-400945是一种选择性PLK4激酶抑制剂,表现出良好的抗肿瘤活性 2,其尚处于临床试验中。因此,开发新型PLK4激酶抑制剂、丰富临床药物种类、提高药品可及性具有重要的医学价值和社会意义。
发明内容
本发明要解决的技术问题是提供一种结构新颖的、具有PLK4激酶抑制活性的化合物,进一步地,本发明提供了一种结构新颖的、具有更优药效活性的PLK4激酶抑制活性的化合物。
本发明可解决的技术问题还包括,本发明化合物可用于治疗由PLK4所介导的癌症性疾病。

说明和定义
在本申请中,除非另有说明,否则本文中所使用的科学和技术名词具有本领域技术人员通常所理解的含义,然而为了更好的理解本发明,下面提供了部分术语的定义。当本申请提供的术语的定义与本领域技术人员所通常理解的含义不相符时,以本申请所提供的术语的定义和解释为准。
术语“药学上可接受的”指在合理的医学判断范围内适合与人类和动物的组织接触使用而无过度的毒性、刺激、过敏反应或其它的问题或并发症,与合理的收益/风险比相当的那些化合物、材料、组合物和/或剂型。
本发明所述的“药学上可接受的盐”指化合物中存在的酸性官能团(例如-COOH、-OH、-SO 3H等)与适当的无机或者有机阳离子(碱)形成的盐,包括与碱金属或碱土金属形成的盐、铵盐,以及与含氮有机碱形成的盐;以及化合物中存在的碱性官能团(例如-NH 2等)与适当的无机或者有机阴离子(酸)形成的盐,包括与无机酸或有机酸(例如羧酸等)形成的盐。这些盐可以在化合物合成、分离、纯化期间就被制备,或者单独使用经过纯化的化合物的游离形式与适合的酸或碱反应。
本发明的化合物能够以非溶剂化以及溶剂化形式存在,溶剂化包括水合物形式。一般而言,溶剂化形式等价于未溶剂化形式,也涵盖在本发明的范围内。
本发明所述的“酯”是指酸和醇失水形成的产物;当本发明化合物结构中存在-COOH基团时,其可与药学上可接受的醇类化合物脱水形成酯;当本发明化合物结构中存在-OH,其可与药学上可接受的有机酸或无机酸类化合物脱水形成酯。所述的酯化合物在有机体内可通过代谢或水解等方式产生本发明活性化合物,所述的酯在体外时,可以具有与游离体相似的生物活性,亦可以没有或具有弱的生物活性。
本发明的化合物存在几何异构体以及立体异构体,根据本发明所述的“异构体”的具体例子例如顺反异构体、对映异构体、非对映异构体、互变异构体、及其外消旋混合物和其他混合物,所有这些混合物都属于本发明的范围之内。
术语“对映异构体”是指互为镜像关系的立体异构体。
术语“互变异构体”是指官能团异构体的一种,其通过一个或多个双键位移而具有不同的连接点,例如,酮和它的烯醇形式是酮-烯醇互变异构体。
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。
术语“顺反异构体”是指分子中双键或者成环碳原子单键不能自由旋转而存在的产生的不同空间排列方式所形成的不同构型。
本发明化合物可通过对映体特异性合成或从对映异构体混合物拆分以制备个别对映异构体形式。常规拆分技术包括使用光学活性酸形成对映异构体对的每一异构体的碱形式的盐(接着分步结晶和游离碱再生)、使用光学活性胺形成对映异构体对的每一对映异构体的酸形式的盐(接着分步结晶和游离酸再生)、使用光学纯酸、胺或醇形成对映异构体对的每一对映异构体中的每一种的酯或酰胺(接着为色谱分离和手性助剂去除)或使用各种众所周知的色谱方法拆分起始物质或最终产物的对映异构体的混合物。

实验例6受试药物在MDA-MB-468移植瘤模型荷瘤鼠中的体内药效学研究
1实验动物
种属:小鼠
品系:CB17SCID小鼠
周龄及体重:体重19-24克
性别:雌性
数量:75只(包括分组剩余鼠)
供应商:北京维通利华实验动物技术有限公司
动物合格证号:20170011007031
2实验方法
人源乳腺癌MDA-MB-468细胞体外单层培养,培养条件为Leibovitz's L-15培养基中加10%胎牛血清,1%双抗(青霉素,链霉素),37℃无CO 2培养。一周两次用胰酶-EDTA进行常规消化处理传代。当细胞饱和度为80%-90%,数量到达要求时,收取细胞,计数,接种。将含有10×10 6个MDA-MB-468细胞的PBS同Matrigel按1:1的比例混合(终体积为200μL)皮下接种于每只小鼠的右前肢腋窝皮下,在细胞接种后第26天,入组动物肿瘤平均体积达到150mm 3时开始分组给药(PG-D0)。每天监测动物的健康状况及死亡情况,例行检查包括观察肿瘤生长和药物治疗对动物日常行为表现的影响如行为活动,摄食摄水量(仅目测),体重变化(每周三次或每天测量一次体重), 外观体征或其它不正常情况。基于各组动物数量记录了组内动物死亡数和副作用。
3肿瘤测量和实验指标
实验指标是考察肿瘤生长是否被抑制、延缓或治愈。每周两次用游标卡尺测量肿瘤直径。肿瘤体积的计算公式为:V=0.5a×b2,a和b分别表示肿瘤的长径和短径。化合物的抑瘤疗效用TGI(%)或相对肿瘤增殖率T/C(%)评价。TGI(%),反映肿瘤生长抑制率。TGI(%)的计算: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)/(溶剂对照组治疗结束时平均瘤体积-溶剂对照组开始治疗时平均瘤体积)]×100%。
相对肿瘤增殖率T/C(%):计算公式如下:T/C%=TRTV平均值/CRTV平均值×100%(TRTV平均值:治疗组RTV的平均值;CRTV平均值:阴性对照组RTV的平均值)。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是分组给药时(即d0)测量所得每只小鼠的肿瘤体积,Vt为某一次测量时每只小鼠的肿瘤体积。然后计算出每组的平均值。V0与Vt取同一只小鼠的肿瘤体积数据。
在实验结束后将检测肿瘤重量,并计算Tweight/Cweight百分比,Tweight和Cweight分别表示给药组和溶剂对照组的瘤重。
统计分析,包括每个组的每个时间点的肿瘤体积的平均值和标准误(SEM)两组间比较用T-test进行分析。p<0.05认为有显著性差异。
4实验结果
药效试验结果显示本发明化合物具有良好的肿瘤抑制效果。
