Definitions
- the present invention relates to compounds selectively inhibiting the activity of DNA-PK protein, also relates to the preparation method of these compounds and their salts, and relates to the method of using these compounds and salts to treat DNA-PK mediated diseases (including cancer).
- DNA-dependent protein kinase is a serine, threonine protein kinase that is activated upon binding to DNA.
- DNA-PK is a trimer formed by the polymerization of a heterodimer composed of a catalytic subunit DNA-PKcs (size 470kD) and two regulatory subunits Ku70 and Ku80 after contact with broken DNA.
- DNA-PKcs is one of the members of the phosphatidylinositol-3 kinase family, which is involved in a variety of biochemical reactions: repair of DNA double strand breaks (DSBs), signal transduction of programmed death, gene surveillance, telomere Structure maintenance, etc.
- DNA double strand break (DNA double strand break, DSB) is the most lethal, and the repair of DSB is mainly through DNA nonhomologous end joining dominated by DNA-dependent protein kinase DNA-PK. , NHEJ) (Cell Res., 2008, 18(1): 114-124).
- DNA-PK also functions in other ways:
- V(D)J chain rearrangement of immunoglobulin and T cell receptor such as deletion of DNA-PKcs or Ku protein, mammalian cells will appear severe combined immunodeficiency (severe combined immunodeficiency, SCID);
- DNA-PKcs is a serine/threonine kinase, a member of the PI-3-K (Phospha tidy lino sito l-3-kinase) kinase family (this family also includes ATM, ATR, etc.), after DNA damage Functional aspects such as cell signal transduction and cell cycle also play a certain role (Int.J.Radiat.Oncol.Biol.Phys.,2005,61(3):915-921).
- DNA-PK inhibitors have the potential to sensitize these therapies. DNA-PK inhibitors can also be effective monotherapy, especially for endogenous DNA damage in tumor cells where other DNA repair pathways are absent.

本发明涉及选择性抑制DNA-PK蛋白活性的化合物,还涉及这些化合物及其盐的制备方法,并且涉及使用此类化合物和盐治疗DNA-PK介导的疾病(包括癌症)的方法。
DNA依赖性的蛋白激酶(DNA-PK)是一种丝氨酸、苏氨酸蛋白激酶,其与DNA结合时被激活。DNA-PK是由一个催化亚基DNA-PKcs(大小470kD)和2个调节亚基Ku70、Ku80组成的异源二聚体在接触断裂DNA后聚合而成的三聚体。其中DNA-PKcs是磷脂酰肌醇-3激酶家族成员之一,参与多种生化反应过程:DNA断裂双链(double strand breaks,DSBs)的修复、程序性死亡的信号传导、基因监视、端粒结构的维持等(FASEB J.,2005,19(7):704-715)。放射线和相当多的抗癌药物均可直接或间接作用于DNA或DNA代谢过程,从而导致DNA的损伤,引发受损DNA修复等一系列细胞反应,而修复的结果就是提高细胞的存活,这也是肿瘤细胞对放化疗抵抗的机制之一。只要抑制这些DNA损伤的修复,就可以提高细胞对放化疗的敏感性(Int.J.Hyperthermia,2008,24(1):17-29)。在DNA损伤中,DNA双链断裂(DNA double strand break,DSB)是最致命的,而DSB的修复主要是通过DNA依赖性蛋白激酶DNA-PK主导的DNA非同源性末端连接(nonhomologous end joining,NHEJ)进行(Cell Res.,2008,18(1):114-124)。DNA-PK除了在DSB的修复中起主要作用以外,还在其他方面发挥功能:
1)免疫球蛋白和T细胞受体的V(D)J链重排,如缺失DNA-PKcs或Ku蛋白,哺乳动物细胞会出现严重的联合免疫缺陷(severe combined immunodeficiency,SCID);
2)维护端粒结构稳定,缺乏Ku或DNA-PKcs可以导致基因组不稳定、细胞生长迟滞和早衰;
3)DNA-PKcs是一个丝氨酸/苏氨酸激酶,为PI-3-K(Phospha tidy lino sito l-3-kinase)激酶家族成员(该家族还包括ATM、ATR等),在DNA受损后的细胞信号转导和细胞周期等功能方面也起一定作用(Int.J.Radiat.Oncol.Biol. Phys.,2005,61(3):915-921)。
一系列因素可以诱导DNA双链断裂,包括化疗、放疗和PARP抑制剂如olaparib。DNA-PK抑制剂有可能助敏这些疗法。DNA-PK抑制剂也能作为有效的单药疗法,特别是肿瘤细胞中其他DNA修复通路缺失的内源性DNA损伤。目前全球已有多个DNA-PK选择性抑制剂进入临床阶段,其中两个药物已进入临床二期,但目前为止尚未有相关药物上市,相关药物的需求尚未得到满足。本发明提供的DNA-PK选择性抑制剂的活性高、耐药性强、临床副作用小,可有效增强肿瘤治疗中放化疗的敏感性,具有较好的经济价值和应用前景。

生物活性实验
DNA-PK化合物生物活性试验方法
1.化合物对DNA-PK的体外酶学活性测定
本专利中化合物对DNA-PK的酶学活性抑制IC50值测定采用时间分辨荧光共振能量转移(TR-FRET)的方法进行。将化合物从1mM开始用100%DMSO进行10倍的梯度稀释(共7个浓度),每个浓度取2μL的化合物加入到48μL的反应缓冲液(50mM HEPES pH7.5,10mM MgCl2,1mM DTT,0.01%Brij-35和1mMEGTA pH8.0)中进行稀释混匀。取2.5μL稀释好的化合物加入到384孔板(OptiPlate-384,购买于PerkinElmer)中,然后加入5μL DNA-PK(Full-length,终浓度为5nM),离心混匀,再加入2.5μL的ATP(终浓度2μM)和Fluorescein-p53 Substrate混合液(终浓度2μM,购买于Thermo)启动反应,总反应体积为10μL。将384孔板放于孵育箱中23℃反应2小时,然后加入10μL的
Tb-anti phospho-p53[pSer15]Antibody(终浓度2nM,购买于Thermo)和EDTA混合液(终浓度10mM)终止反应。在孵育箱中再次孵育1小时后,在Envision(购 买于PerkinElmer)上读取荧光值(340nm激发,检测520nm与490nm的发射光,二者比值为酶的活性信号)。每个化合物分别在7个浓度下测定DNA-PK的酶学活性信号,数据使用GraphPad Prism软件计算得到该化合物的IC50值。部分实施例酶学活性见表1。

本发明是在人乳腺癌细胞MDA-MB-468中建立的DNA-PK抑制剂与化疗药物Doxorubicin联用条件下建立的对细胞增殖抑制的检测方法。具体方法如下:人乳腺癌细胞MDA-MB-468细胞使用RPMI-1640培养基(购买于Biological Industries,BI),加10%的胎牛血清(FBS,购买于Hyclone)和1%青霉素/链霉素双抗(P/S,购买于Life Techonology)进行培养,培养条件为(37℃,5%CO2)。进行化合物检测的前一天,将MDA-MB-468细胞以1000个细胞/190μL/孔的浓度铺于96孔板(#3917,购买于Corning)中。24小时后加入Doxorubicin至终浓度10nM(DMSO终浓度0.1%),将待测化合物从10mM开始用100%DMSO进行3倍的梯度稀释(共10个浓度),然后每个浓度取2μL的化合物加入到48μL的RPMI-1640培养基中进行稀释,稀释后的不同浓度的待测化合物各取5μL加入到铺好的细胞悬液中。将化合物与细胞在细胞培养箱中共孵育120h(5天)后,吸尽培养基后加入25μL的Cell-Titer Glo(G7570,购买于Promega)试剂再次孵育5-10分钟。之后在CLARIO starPlus(购于BMG)酶标仪上读取荧光值,数据使用GraphPad Prism软件计算得到该化合物对细胞增殖的抑制的IC50值。

4.化合物对人非小细胞肺癌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
实验动物:雌性BALB/c-nude小鼠,6~8周龄,体重18-22克。
实验方法与步骤:
1)细胞培养
人非小细胞肺癌NCI-H1703细胞体外培养,RPM11640培养基中加10%胎牛血清,100U/mL青霉素和100μg/mL链霉素,37℃5%CO2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。
2)肿瘤接种
将0.1mL(5×106个)NCI-H1703细胞(加30%基质胶)皮下接种于每只小鼠的背部左右两侧,肿瘤平均体积达到约150mm
3时开始分组给药。
3)受试物的配制:
实施例1和实施例3均配制成3mg/mL的混悬溶液,溶媒为0.5%HPMC+0.1%Tween80。
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: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=Vt/Vo,其中V
0是分组给药时(即第0天)测量所得肿瘤体积,Vt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 积一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%。
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18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。p<0.05认为有显著性差异。
6)实验结果和结论
实施例1在30mg/kg剂量下(一天两次给药)的实验结果见表4。实施例31在30mg/kg剂量下(一天两次给药)的实验结果见表5。
表4.实施例1的体内药效学数据
表5.实施例31的体内药效学数据
注:
a.平均值±SEM,n=5;
b.肿瘤生长抑制由T/C和TGI(TGI(%)=[1-(T
18-T
0)/(V
18-V
0)]×100)计算;
c.p值运用t-test进行分析肿瘤体积相对值(RTV)所得;
结论:在本实验中,与对照组相比,本发明实施例中的化合物具有显著的抑瘤作用,且荷瘤鼠对化合物均显示出良好的耐受性。
