  • the present invention relates to a DNA-PK inhibitor, in particular to a compound represented by formula (II) or a pharmaceutically acceptable salt thereof, and its application in the preparation of drugs related to DNA-PK inhibitors.
  • DNA breaks especially double-strand breaks (DSBs) are extremely serious damages that can cause loss of genetic material, gene recombination, and lead to cancer or cell death.
  • Eukaryotic cells have evolved a variety of mechanisms to deal with the serious threats caused by DNA double-strand breaks. This is the DNA damage response mechanism (DDR), which mainly includes DNA damage detection, signal transduction, and damage repair.
  • DDR DNA damage response mechanism
  • DNA double-strand break repair mainly includes homologous end joining (HR) repair and non-homologous end joining (NHEJ) repair. In higher eukaryotes, NHEJ repair, which is preferentially used during the early G1/S phase, is the main mechanism.
  • DDR initial damage factors such as MRN will detect and recognize the damage site, recruit phosphoinositide kinase family members (ATM, ATR, DNA-PK), phosphorylate H2AX to promote the formation of ⁇ H2AX, guide downstream signal transduction and recruit related proteins to complete the receptor. Repair of damaged DNA.
  • DNA-PK catalytic subunit which belongs to the PI3K-related kinase (PIKK) family, mainly targets non-homologous DNA double-strand breaks End join (NHEJ) repair is an important member of DNA damage repair.
  • NHEJ non-homologous DNA double-strand breaks End join
  • the Ku70/Ku80 heterodimer specifically connects to the double-stranded damage through a pre-formed channel, recognizes double-strand breaks and binds to the broken ends separately, and then follows the DNA in an ATP-dependent manner. The strands slid a certain distance to both ends to form a KU-DNA complex and recruit DNA-PKcs to bind to the double-strand break.

发明领域
本发明涉及DNA-PK抑制剂,具体涉及式(II)所示化合物或其药学上可接受的盐,及其在制备DNA-PK抑制剂相关药物中的应用。
背景技术
DNA断裂尤其是双链断裂(DSBs)是一种极为严重的损伤,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。真核细胞进化出了多种机制来应对DNA双链断裂造成的严重威胁,这便是DNA损伤应答机制(DDR),主要包括DNA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同源末端连接(HR)修复和非同源末端连接(NHEJ)修复。在高等真核生物中,主要以优先地在早期G1/S期期间使用的NHEJ修复为主要机制。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,引导下游信号传导并募集相关蛋白完成受损DNA的修复。
DNA依赖性蛋白激酶催化亚单位(DNA-PK catalytic subunit,DNA-PKcs),属于磷酸肌醇-3-激酶相关蛋白(PI3K-related kinase,PIKK)家族,主要针对DNA双链断裂的非同源末端连接(NHEJ)修复,是DNA损伤修复的重要成员。DNA双链损伤修复时,Ku70/Ku80异源二聚体通过一个预先形成的通道特异性地连接到双链损伤处,识别双链断裂并与断裂端分别结合,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复合物并招募DNA-PKcs到双链断裂处与之结合,随后Ku二聚体向内移动,激活DNA-PKcs并使其自身磷酸化,最后,磷酸化的DNA-PKcs引导损伤信号传导并招募DNA末端加工相关蛋白如PNKP、XRCC4、XLF、Pol X和DNA连接酶IV等参与完成双链断裂修复。
目前,肿瘤治疗中常用的DNA损伤性化疗药物(如博来霉素,拓扑异构酶II抑制剂如依托泊苷和多柔比星)和放疗发挥作用的主要机制就是造成DNA分子的致死性的双链断裂,进而诱导肿瘤细胞的死亡。研究表明,经过放化疗治疗的肿瘤组织中均发现DNA-PK的高表达,而DNA-PKcs活性的增加在一定程度上增强了受损DNA的修复,阻止了肿瘤细胞死亡,导致了对放化疗产生耐受。此外,放化疗治疗后肿瘤组织中存活的细胞往往是对治疗不敏感的高DNA-PKcs活性细胞,这也是疗效不好和预后差的原因。通过与放化疗药物联用,DNA-PK抑制剂可以抑制DNA-PKcs活性,从而大大减少肿瘤DNA修复,诱导细胞进入凋亡程序,达到更佳的治疗效果。
ATM在同源末端链接(HR)修复中起到重要作用,当肿瘤细胞因缺陷缺乏ATM时,DNA断裂修复会更加依赖于DNA-PKcs主导的NHEJ修复以使其存活。因此,DNA-PK抑制剂同样可以作为单一药物在具有其他DNA修复途径缺陷时的肿瘤中发挥治疗效果。
本发明的DNA-PK小分子抑制剂,不仅可以作为单一药物在具有其他DNA修复途径缺陷时的肿瘤中发挥治疗效果。也可以通过与放化疗药物联用,增强肿瘤组织对放化疗的敏感性,克服耐药问题,增强对多种实体瘤和血液瘤的抑制作用。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。

实验例4:人非小细胞肺癌NCI-H1703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:研究待测化合物对人小细胞肺癌NCI-H1703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18-22克。
实验方法与步骤:
4.1细胞培养
人非小细胞肺癌NCI-H1703细胞体外培养,RPMI1640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。当细胞饱和度为80%-90%,数量到达要求时,收取细胞,计数,接种。
4.2肿瘤细胞接种(肿瘤接种)
将0.2mL(5×10 6个)NCI-H1703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131mm 3时开始分组给药。
4.3受试物的配制:
化合物配制成10mg/mL的混悬溶液,溶媒为0.5%HPMC+1%Tween 80。
4.4肿瘤测量和实验指标
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。相对肿瘤增殖率T/C(%)=T RTV/C RTV×100%(T RTV:治疗组RTV平均值;C RTV:阴性对照组RTV平均值)。根据肿瘤测量的结果计算出相对肿瘤体积(RTV),计算公式为RTV=V t/V 0,其中V 0是分组给药时(即第0天)测量所得肿瘤体积,V t为某一次测量时的肿瘤体积,T RTV与C RTV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%。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
统计分析基于试验结束时RTV的数据运用SPSS软件进行分析。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,如果方差齐(F值无显著性差异),应用Tukey‘s法进行分析;如果方差不齐(F值有显著性差异),应用Games-Howell法进行检验。p<0.05认为有显著性差异。 4.6实验结果和结论
化合物2在100mg/kg剂量下(一天两次给药)的实验结果见表4。化合物1在90mg/kg剂量下(一天两次给药)的实验结果见表5。
注:a.平均值±SEM,n=6;b.肿瘤生长抑制由T/C和TGI(TGI(%)=[1-(T 21-T 0)/(V 21-V 0)]×100)计算;c.p值运用one-way ANOVA进行分析肿瘤体积相对值(RTV)所得;d.化合物2及其空白对照所用实验动物的供应商为北京维通利华实验动物技术有限公司(浙江分公司);e.化合物1及其空白对照所用所用实验动物的供应商为上海西普尔-必凯实验动物有限公司。
