技术领域
本发明涉及一系列DNA-PK激酶抑制剂,其用途和合成方法,具体涉及式(I)所示化合物、其异构体或其药学上可接受的盐在制备DNA-PK激酶抑制剂相关药物中的应用。
背景技术
DNA双链断裂(DSBs)作为一种严重的DNA损伤,会造成遗传物质的丢失、基因重组,从而导致癌症或细胞死亡。生物体为维持基因稳定性与细胞活性进化出了DNA损伤应答(DDR)机制进行损伤的检测、信号传导以及损伤修复。DNA双链断裂修复主要包括两种:同源末端链接(HR)修复和非同源末端链接(NHEJ)修复。DDR初期损伤因子如MRN等会检测识别损伤位点,募集膦酯酰肌醇激酶家族成员(ATM、ATR、DNA-PK),磷酸化H2AX促进γH2AX形成,募集相关信号蛋白(如53BP1、Chk1、Chk2、BRCA1、NBS1)等传导损伤信号,使细胞进入细胞周期阻滞状态并募集相关修复蛋白,使损伤DNA修复。
DNA-PK作为DNA损伤修复的重要成员,主要针对非同源末端双链的断裂。由六个核心因子组成:KU70、KU80、DNA-PKcs、CRCC4、连接酶IV和Artemis,DNA双链损伤修复时,KU分子通过一个预先形成的通道特异性地连接到双链损伤处,分别识别并结合DNA链末端,然后以ATP依赖的方式沿DNA链分别向两端滑动一段距离,形成KU-DNA复合物,吸引DNA-PKcs到损伤部位,与之结合并激活激酶活性,进而磷酸化参与修复及损伤信号传导的一系列蛋白,完成修复。
目前,通过放疗和化疗(拓扑异构酶II、博来霉素、阿霉素、依托泊苷)等方式来诱导DNA损伤来是控制肿瘤的生长主要手段之一。但研究表明,经过放化疗后的肿瘤组织中DNA-PK高表达,不断修复放化疗损伤的肿瘤细胞,成为放化疗耐药的主要原因之一。
本发明旨在发现一种DNA-PK小分子抑制剂,通过与放化疗药物联用,抑制DNA-PK活性,从而大大减少肿瘤DNA修复,诱导细胞进入凋亡程序。可以在很大程度上克服放化疗耐药问题,增强对小细胞肺癌、头颈癌、结直肠癌、胰腺癌等各种肿瘤的抑制作用。此类化合物具有良好的活性,并表现出了优异的效果和作用,具有广阔的前景。
专利WO2018178133公开了化合物M3814,属于DNA-PK激酶抑制剂,抗肿瘤小分子化合物,其结构式如下:

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地。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都有独立地选项。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。当所列举的取代基中没有指明其通过哪一个原子连接到被取代的基团上时,这种取代基可以通过其任何原子相键合,例如,吡啶基作为取代基可以通过吡啶环上任意一个碳原子连接到被取代的基团上。
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

实验目的:研究待测化合物对人小细胞肺癌NCI-H69细胞皮下异种移植肿瘤BALB/c裸小鼠模型的体内药效学
实验动物:雌性BALB/c裸小鼠,6-8周龄,体重15-22克;供应商:上海灵暢生物科技有限公司(灵暢,上海)
实验方法与步骤:
3.1细胞培养
人小细胞肺癌NCI-H69细胞(ATCC,货号:HTB-119和ECACC-95111733)体外悬浮培养,培养条件为RPMI-1640培养基中加10%胎牛血清,100U/mL青霉素和100μg/mL链霉素,37℃,5%CO 2孵箱培养。一周两次进行常规传代。当细胞饱和度为80%-90%,数量到达要求时,收取细胞,计数,接种。
3.2肿瘤细胞接种(肿瘤接种)
将0.2mL(10×10 6个)NCI-H69细胞(加基质胶,体积比为1:1)皮下接种于每只小鼠的右后背,肿瘤平均体积达到约110-120mm 3时开始分组给药。
3.3受试物的配制:
受试化合物配制成5mg/mL的澄清溶液,溶媒为10%DMSO+50%聚乙二醇400+40%水。
3.4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×b 2,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)】×对照组。
相对肿瘤增殖率T/C(%):计算公式如下:T/C%=TRTV/CRTV组开始治疗时平(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=V t/V 0,其中V 0是分组给药时(即d 0)测量所得平均肿瘤体积,V t为某一次测量时的平均肿瘤体积,TRTV与CRTV取同一天数据。
在实验结束后将检测肿瘤重量,并计算T/重量百分比,T重量和C重量分别表示给药组和溶媒对照组的瘤重。
3.5统计分析
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)。治疗组在试验结束时给药后第21天表现出最好的治疗效果,因此基于此数据进行统计学分析评估组间差异。两组间比较用T-test进行分析,三组或多组间比较用one-way ANOVA进行分析,如果F值有显著性差异,应用Games-Howell法进行检验。如果F值无显著性差异,应用Dunnet(2-sided)法进行分析。用SPSS 17.0进行所有数据分析。p<0.05认为有显著性差异。
3.6试验结论和讨论
1)与溶媒组相比,在人乳腺癌裸鼠移植瘤模型中,M3814(40mg/kg,口服,每日一次)+依托泊苷(10mg/kg,IP,3天给药,4天停药),实施例2(40mg/kg,口服,每日一次)+依托泊苷(10mg/kg,腹腔注射给药,3天给药,4天停药),实施例19(40mg/kg,口服,每日一次)+依托泊苷(10mg/kg,IP,3天给药,4天停药),和实施例19(80mg/kg,口服,每日一次)+依托泊苷(10mg/kg,IP,3天给药,4天停药)与溶剂对照组相比有显著性差异,TGI分别为74%、89%、64%和80%。各组体重变化分别为:M3814(40mg/kg,-16.00%),实施例2(40mg/kg,-16.66%),实施例19(40mg/kg,-5.88%),和实施例19(80mg/kg,0.13%)。实施例19具有显著的抑瘤效果和更高的安全性。

2)给药24天时,M3814(40mg/kg,口服,每日一次)+依托泊苷(10mg/kg,IP,3天给药,4天停药),实施例19(40mg/kg,口服,每日一次)+依托泊苷(10mg/kg,IP,3天给药,4天停药)和实施例19(40mg/kg,PO,BID)+依托泊苷(10mg/kg,IP,3天给药,4天停药)的T/C分别为43.1%、38.6%和28.4%,TGI分别为66.1%、70.5%和81.5%,均有明显的抑制肿瘤生长的作用,与溶剂对照组相比均为p<0.05。M3814(40mg/kg,QD),依托泊苷(10mg/kg),实施例19(40mg/kg,BID),实施例19(10mg/kg,BID)+依托泊苷(10mg/kg,IP,3天给药,4天停药),实施例19(20mg/kg,QD)+依托泊苷(10mg/kg,IP,3天给药,4天停药)的T/C分别为84.1%、75.6%、85.8%、61.2%和50.6%,TGI分别为19.8%、33.4%、16.8%、46.5%和56.8%,与溶剂对照相比p值分别为0.603、0.570、0.471、0.005和<0.001,具有一定的抑瘤作用。
根据瘤重与根据体积计算出的T/C值接近,并且趋势一致。上述结果提示在人小细胞肺癌NCI-H69裸鼠移植瘤模型中,M3814(40mg/kg,口服,每日一次)+依托泊苷(10mg/kg,IP,3天给药,4天停药)联用组具有显著抗肿瘤作用;此外,实施例19(40mg/kg,口服,每日一次)+依托泊苷(10mg/kg,IP,3天给药,4天停药)和实施例19(40mg/kg,PO,BID)+依托泊苷(10mg/kg,IP,3天给药,4天停药)联用组也具有显著抗肿瘤作用,并且后者的抗肿瘤作用具有量效依赖的趋势(高剂量组与低剂量组相比p<0.05)。实施例19(40mg/kg,PO,BID)+依托泊苷(10mg/kg,IP,一周前三天给药,后四天停药)与两个对应单药组相比p值均<0.05,有协同效应。

实验例4:人头颈癌FaDu细胞皮下异种移植肿瘤BALB/c裸小鼠模型的体内药效学研究:
实验目的:本试验使用人头颈癌FaDu细胞皮下异种移植肿瘤裸小鼠模型评价受试化合物的抗肿瘤作用实验动物:雌性BALB/c裸小鼠,6-8周龄,体重17-23克;供应商:上海西普尔-必凯实验动物有限公司
实验方法与步骤:
4.1细胞培养
人头颈癌FaDu细胞(ATCC,马纳萨斯,弗吉尼亚州,货号:HTB-43),体外单层培养,培养条件为EMEM培养基中加10%胎牛血清,100U/mL青霉素和100μg/mL链霉素,37℃,5%CO 2孵箱培养。一周两次用胰酶-EDTA进行常规消化处理传代。
4.2肿瘤细胞接种(肿瘤接种)
每只小鼠于右后背位置皮下接种0.1mL(5×10 6)FaDu细胞,肿瘤平均体积达到约106mm 3时,采用随机分组,开始给药。
4.3受试物的配制:
受试化合物配制成5mg/mL的澄清溶液,溶媒为10%DMSO+50%聚乙二醇400+40%水;每三天配制一次。
4.4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×b 2,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)】×对照组。
相对肿瘤增殖率T/C(%):计算公式如下:T/C%=TRTV/CRTV组开始治疗时平(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=V t/V 0,其中V 0是分组给药时(即d 0)测量所得平均肿瘤体积,V t为某一次测量时的平均肿瘤体积,TRTV与CRTV取同一天数据。
在实验结束后将检测肿瘤重量,并计算T/重量百分比,T重量和C重量分别表示给药组和溶媒对照组的瘤重。
4.5统计分析
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)。治疗组在试验结束时给药后第21天表现出最好的治疗效果,因此基于此数据进行统计学分析评估组间差异。两组间比较用T-test进行分析,三组或多组间比较用one-way ANOVA进行分析,如果F值有显著性差异,应用Games-Howell法进行检验。如果F值无显著性差异,应用Dunnet(2-sided)法进行分析。用SPSS 17.0进行所有数据分析。p<0.05认为有显著性差异。
4.6试验结论和讨论
1)本实验评价了实施例19化合物在人头颈癌FaDu细胞异种移植瘤模型中的药效,以溶媒组为参照。给药21天时,放疗组(2Gy,放疗5天,停两天),M3814(50mg/kg,口服,每日一次)+放疗组(2Gy,放疗5天,停两天),实施例19(25mg/kg,口服,每日一次)+放疗组(2Gy,放疗5天,停两天)和实施例19(50mg/kg,口服,每日一次)+放疗组(2Gy,放疗5天,停两天)的T/C值分别为4.35%,0.24%,0.08%和0.08%,TGI分别为103.91%,108.46%,108.61%和108.64%,均有明显的抑制肿瘤生长的作用,与溶剂对照组相比均为均为p<0.001。M3814(50mg/kg,口服,每日一次)和实施例19(50mg/kg,口服,每日一次)的T/C值分别为99.60%和114.35%,TGI分别为-0.43%和-15.37%,与溶剂对照组相比p=1.000和0.990,无明显抑瘤作用。
上述结果提示在人头颈癌FaDu细胞裸鼠移植瘤模型中,放疗组(2Gy,放疗5天,停两天)和M3814(50mg/kg,口服,每日一次)+放疗组(2Gy,放疗5天,停两天)联用组均具有显著抗肿瘤作用;此外,实施例19(25mg/kg,口服,每日一次)+放疗组(2Gy,放疗5天,停两天)和实施例19(50mg/kg,口服,每日一次)+放疗组(2Gy,放疗5天,停两天)联用组均具有显著抗肿瘤作用。详见表9和表10。
2)在此模型中所有给药组动物的体重均未见明显下降,而进行辐照的4组动物的体重略有下降,但平均值均低于10%。未进行辐照的动物肿瘤在分组给药后第21天半数出现破溃和结痂,其中Group3(M3814,50mg/kg)一只动物动物在分组给药后第23天发现死亡;Group 4(实施例19,50mg/kg)的一只动物因肿瘤破溃达到安乐死标准,在开始给药后第22天执行安乐死。Group 1(Vehicle)、Group 3(M3814, 50mg/kg)和Group 4(实施例19,50mg/kg)因平均肿瘤体积接近2000mm3,三组所有剩余动物均于开始给药后24天执行安乐死。

表10各组不同时间点的瘤体积
Figure PCTCN2020098198-appb-000075
注:a.平均值±SEM,n=8。
讨论:在本次试验中,单独辐照组与联用组对肿瘤生长均有显著抑制作用,在治疗期间,联用组的平均肿瘤体积始终小于单独辐照组,且所有联用组的平均肿瘤体积均在分组后第31天降至零,而同日单独辐照组的平均肿瘤体积达到最小值24mm 3。停药后7周时间中观察到单独辐照组动物的肿瘤开始反弹,而联用组的肿瘤均完全消失且均未反弹,表明较低剂量的DNA-PK抑制剂即可以增强放疗的治疗效果,且联用具有长久的抑瘤效果。
