  • the present invention relates to the field of pharmaceutical chemistry, in particular to a dihydropteridone derivative containing a phenylheteroaryl group and its use in preparing a drug for treating and/or preventing cancer.
  • Cancer also known as malignant tumor, is a malignant disease caused by abnormal differentiation and proliferation of normal tissue cells. Cancer is the second leading cause of death in the world and has gradually become an increasingly serious public health problem. According to statistics, there were 18.1 million cancer cases and 9.6 million cancer deaths in 2018. The current form of cancer in my country is serious. According to statistics, of the 9.6 million cancer deaths in the world in 2018, 30% (2.9 million) of the deaths occurred in China.
  • the cancer incidence rate in China (201.7/100,000) is comparable to the global total incidence rate (197.9/100,000), but the cancer mortality rate in China is much higher (130.1/100,000 in China, 102.6/100,000 in the UK, and 91.0/100,000 in the United States). Cancer has become the leading cause of death among Chinese residents and has placed a heavy burden on a large number of families. Therefore, the research on anti-tumor drugs and their related target inhibitors has important clinical and social value.
  • PLKs Poly-like kinases
  • Ser/Thr protein kinases found in eukaryotes. They have a unique cell cycle regulation mechanism and play an important role in the proliferation and differentiation of tumor cells. Using PLKs as a target to find anti-tumor drugs with a new mechanism has become an important branch of targeted drug research.
  • PLK1 The structure of PLK1 in the human body includes two important domains, namely the N-terminal kinase domain, which contains 252 amino acids; and the C-terminal PDB domain, which contains 60 to 70 amino acids.
  • the crystal structure analysis of the two important domains of the protein, the C-terminal and the N-terminal, has been completed and reported in recent years.
  • the crystal structure of the N-terminal kinase domain of PLK1 is a classic protein kinase structure, that is, the N-terminal antiparallel ⁇ -fold protrusion and the C-terminal ⁇ -helical protrusion form a pocket for ATP binding in space, and the highly conserved hinge region connecting the two protrusions is the main site of the main chain and ligand binding reaction.
  • PLK1 kinase and inhibitors such as phenylalanine at the bottom of the ATP binding pocket, cysteine at the top (leucine in common kinases), the pocket in the hinge region, and the positively charged residues outside the adenine pocket. These specific sites provide a structural basis for the design of specific PLK1 inhibitors.
  • PLK1 in key cell cycle processes is obvious. Its most conserved function is to precisely control the microtubules in the centrosome, spindle, and kinetochore.
  • the expression of the PLK1 gene is regulated by the cell cycle and its expression level changes with the stage of the cell cycle. Usually in the early stage of mitosis, PLK1 accumulates in the center of the spindle, and gradually migrates from the spindle to the equatorial plate after the middle and late stages of mitosis. At the end of mitosis, PLK1 accumulates in the central region of the spindle and phosphorylates HsCYK4 to activate the RhoA enzyme.
  • RhoA enzyme completes a cell cycle by regulating the contraction of the contractile ring and then the cytoplasm divides. Therefore, PLK1 expression is low in the G1 and S phases, gradually increases in the G2 phase, and reaches a peak in the M phase. After cell division is completed, PLK1 expression will drop sharply and then enter the next cell cycle.
  • PLK1 also plays an important role in the maturation of the centrosome, the maturation of sister chromosomes, the regulation of the microtubule organizing center, and cell division.
  • PLK1 inhibitors in clinical research around the world, including dihydropteridinone compounds BI2536 (Phase II) and Volasertib (Phase III), tricyclic compounds NMS-P397 (Phase II), thiophene compounds GSK461364 (Phase I), pyrimidine diazepine ketone compounds TAK960 (Phase I) and other Rigosertib (Phase III).

Description

含苯联杂芳基的二氢喋啶酮衍生物及其用途 技术领域
本发明涉及药物化学领域,具体的说是一种含苯联杂芳基的二氢喋啶酮衍生物及其在制备治疗和/或预防癌症的药物中的用途。
背景技术
癌症又称恶性肿瘤,是正常组织细胞异常分化增生而导致的恶性疾病。癌症是全球第二大死亡原因,并且逐渐成为日益严重的公共卫生问题。据统计,2018年全球癌症病例为1810万,癌症死亡病例960万。我国目前癌症患病形式严重。据统计,在2018年全球960万例癌症死亡病例中,有30%(290万)的死亡病例发生在中国。中国的癌症发病率(201.7/100,000)与全球总发病率(197.9/100,000)相当,但中国的癌症死亡率要高得多(中国为130.1/100,000,英国为102.6/100,000,美国为91.0/100,000)。癌症已然成为中国居民死亡的主要原因,并为大量家庭造成沉重的负担。因此,抗肿瘤药物及其相关靶点抑制剂的研究具有重要的临床和社会价值。
PLKs(Polo-like kinases,Polo样激酶)是一类存在于真核生物中的Ser/Thr蛋白激酶,其具有独特的细胞周期调控机制,在肿瘤细胞增殖分化中起重要作用。以PLKs为靶标,寻找全新机制的抗肿瘤药物,已是靶向药物研究中的一个重要分支。
目前,在所有PLKs家族成员中,科研人员对于PLK1的研究是最为透彻的,人体内PLK1结构包括两个重要的结构域,即N端的激酶结构域,包含252个氨基酸;C端的PDB结构域,包含60~70个氨基酸。该蛋白C端、N端两个重要结构域的晶体结构解析已在近年来相继完成并报道。PLK1的N端激酶结构域晶体结构为经典的蛋白激酶结构,即由N端反向平行的β-折叠突起和C端的α-螺旋突起空间上形成供ATP结合的口袋,而连接两端突起的高度保守的铰链区域是主链与配体结合反应的主要部位。与其他传统的激酶结构相比,一些特定的位点还存在于PLK1激酶与抑制剂的结合区域:如ATP结合口袋底部的苯丙氨酸、顶部的半胱氨酸(在常见激酶中为亮氨酸)、铰链区域的口袋、以及腺嘌呤口袋外侧带正电荷的残基,这些特定的位点为设计特异的PLK1抑制剂提供了结构基础。
PLK在关键细胞周期过程中的重要性显而易见,其最保守的功能是对中心体、纺锤体和动粒体内的微管进行精确的周期控制。PLK1基因的表达受细胞周期调控并且其表达水平随细胞周期的阶段变化而变化。通常在有丝分裂早期,PLK1聚集在纺锤体的中心,在有丝分裂进行至中后期后逐渐从纺锤体向赤道板迁移。在有丝分裂末期,PLK1聚集在纺锤体的中央区,磷酸化HsCYK4,使其激活RhoA酶。RhoA酶通过调控收缩环收缩,进而细胞质分裂,完成一个细胞周期。因此,在G1期和S期PLK1表达较低,在G2期逐渐升高,在M期达到峰值。细胞分裂完成后,PLK1表达将急剧下降,然后进入下一个细胞周期循环。PLK1除了调节有丝分裂进程之外,其对中心体的成熟、姐妹染色体的成熟、微管组织中心的调节以及细胞分裂也发挥着重要作用。
目前,随着药物化学、肿瘤学以及药理学的不断发展,全球针对PLK1靶向药物的研究已取得一定成效。目前全球有多个PLK1抑制剂进入临床研究,其中主要包括二氢蝶啶酮类化合物BI2536(Phase II)与Volasertib(Phase III)、三环类化合物NMS-P397(Phase II)、噻吩类化合物GSK461364(Phase I)、嘧啶并二氮杂卓酮类化合物TAK960(Phase I)以及其他类Rigosertib(Phase III)等。但PLK亚型间高同源性及给药方式造成的问题使得至今还没有任何PLK1小分子抑制剂获批上市,临床迫切需要寻找更多的新型、高效PLK1抑制 剂,为肿瘤等疾病的治疗提供新的选择。

将50μL初始浓度为20nM的化合物的DMSO溶液转移到384孔稀释板中,用DMSO以5倍的浓度梯度稀释化合物。使用SYSTEM(购置于LABCYTE)将0.025μL稀释的化合物溶液转移到384测试板中,平行两次。将2.5μL酶溶液(PLK1激酶购置于Carna)加入384孔测试板中,1000rpm离心1min后,在25℃下孵育10min。将2.5μL底 物(ATP和底物)工作溶液加入384孔测试板中,在25℃下孵育60min,加入4μL ADP-Glo溶液,在25℃下孵育40min后,加入8μL检测工作溶液,在25℃下继续孵育40min后,使用BMG酶标仪读取数据,按照公式Percent inhibition(%inh)for compound well=100*(ave High control-cpd well)/(ave High control-ave Low control)计算抑制率后,使用XLfit 5.5.0从非线性回归方程拟合化合物的IC50

由上述表中记载通式化合物均具有良好的PLK1的抑制活性,大部分化合物相当或优于阳性对照药BI 6727(Volasertib,购买于MCE)。

CCK-8法检测化合物的抗增殖活性(MDA-MB-231和MV4-11细胞系)
将处于对数生长期的细胞以8~15×104个/mL接种至96孔板中,细胞液体积为100μL/孔。向每孔加入100μL不同浓度的药液,每个浓度设置三个复孔,于标准条件下孵育48h。孵育结束后取出96孔板,每孔加入20μL的CCK-8溶液(2-(2-甲氧基-4-硝基苯基)-3-(4-硝基苯基)-5-(2,4-二磺酸苯)-2H-四唑单钠盐,商购于MCE),继续孵育4h后取出,置于微量振荡仪上振荡5min。在酶标仪上于450nm测得各孔的吸光度(OD)。
按公式计算细胞体外增殖的抑制率(Inhibition Rate,IR):
IR%=(ODcontrol-ODsample)/(ODcontrol-ODblank)×100%
式中,ODcontrol:未加药孔的OD值;ODsample:加药孔的OD值;ODblank:在CCK-8法中为只加培养基孔的OD值,在MTT法中为只加DMSO孔的OD值。
最后,用SPSS软件输入数据并绘制抑制率-浓度曲线计算IC50
