Description
技术领域
本发明涉及2,4-二苯胺基嘧啶类化合物、组合物及用途,属于医药技术领域。
背景技术
蛋白酪氨酸激酶(protein tyrosine kinase,PTKs)通过控制细胞的信号传导通路调节细胞的生长、分化、凋亡等一系列生理生化过程。受体型酪氨酸激酶是一类横跨细胞膜相对较大的激酶,其具有配体结合的胞外结构域、跨膜结构域和起激酶作用—在磷酸化特定酪氨酸残基并且由此影响细胞增殖的胞内结构域。在一般人类癌症中(如肺癌、乳腺癌、胃癌、卵巢癌、淋巴瘤)已发现所述激酶的异常表达。蛋白酪氨酸激酶已成为抗肿瘤药物研究开发的重要靶点之一。
BTK是非受体蛋白酪氨酸激酶Tec家族成员之一,主要表达在造血细胞(除T细胞外),在BCR信号通路中,随着BCR的激活,BTK依赖Syk、Lyn活化,活化后的BTK 可以进一步磷酸化PLCγ2,进而引起包括MAPK、NFκB等下游信号的活化。BTK在B 淋巴细胞的生成过程中起着不可替代的作用。BTK可以通过激活细胞周期正向调控因子和分化因子来控制B细胞的发育、分化,也能通过调节促凋亡和抗凋亡蛋白的表达来控制B细胞的存活和增殖。BTK的持续激活是慢性淋巴细胞白血病(CLL)发展的一个先决条件,BCR-BTK信号传递异常会促进弥漫性大B细胞淋巴瘤(DLBCL)中活化B细胞亚型的存活。BTK小分子抑制剂对于治疗血液恶性肿瘤和自身免疫失调疾病具有良好前景。Ibrutinib(依鲁替尼)是一种口服的布鲁顿酪氨酸激酶(BTK)抑制剂,由美国加州的Pharmacyclics公司开发(US 7514444,CN101610676A),已被美国FDA批准上市,用于治疗套细胞淋巴瘤(MCL)和CLL。其他多个化合物,如 CC-292(AVL-292)(US8563568,WO2014100748A1)是一个通过共价结合的,可以口服的高选择性BTK抑制剂,其IC50小于0.5nmol/L,展示了比其他被测激酶至少1400 倍的选择性,目前正进行PhaseI研究(Evans,E.K.,et al.J.Pharmacol Exp.Ther.2013, 346,219-228.);又如ONO-4059(Yasuhiro,T.,et al.Blood 2013,122,5151-5151.)是依鲁替尼类似物,高度选择性抑制BTK,IC50为23.9nmol/L,进入PhaseI研究。此外 CNX-774(Akinleye,A.,etal.J.Hematol Oncol.2013,6,59.)也是一种口服有效的高选择性BTK抑制剂,IC50小于1nmol/L,涉及的专利如:WO2010141406 A2、 US20140256759 A1、CN102083800 A。
JAK(Janus酪氨酸激酶),包括JAK1、JAK2、JAK3和TYK2四个成员。JAKs 在多种细胞因子的信号传导过程中发挥重要作用。JAK1、JAK2及TYK2广泛存在于各种组织和细胞中,而JAK3主要分布于淋巴细胞中,研究表明,JAK3不仅在B和 T淋巴细胞的成熟起着关键作用,其对于维持T细胞功能也是必不可少的。因此开发 JAK选择性抑制剂对于骨髓增生性肿瘤和白血病的治疗有很大的医疗价值和市场潜力。Tofacitinib(CP-690550)是辉瑞公司研发的一种口服JAK3通路抑制剂。Tofacitinib 以细胞内信号转导通路为靶点,作用于细胞因子网络的核心部分。其对JAK3的抑制强度是对JAK1及JAK2的5~100倍。Tofacitinib(US20040102627,US8309716, WO2008058528)是治疗类风湿性关节炎(rheumatoidarthritis)的首创药物(first-in-class drug),于2012年,被美国食品和药物管理局(FDA)批准上市。Cerdulatinib(PRT-062070) 是一种具有口服活性的多靶点酪氨酸激酶抑制剂,对JAK1/JAK2/JAK3/TYK2和Syk 的IC50分别为12nM/6nM/8nM/0.5nM和32nM。也能够抑制测试的其他19种激酶, IC50均低于200nM(Coffey,G.,J.Pharmacol Exp.Ther.2014,351,538-548.)。Fedratinib (SAR302503,TG101348)是一种选择性JAK2抑制剂(Geron,I.,etal.Cancer Cell 2008,13,321-330.),在无细胞试验中IC50为3nM,作用于JAK2比作用于JAK1和 JAK3选择性高35和334倍,已进入临床PhaseⅡ研究(WO 2012060847A1)。
另外与本发明密切相关的专利如:WO 2015039613A1、WO 2015182628A1、CN104311573 A。
鉴于治疗癌症的迫切需要,本领域有必要开发新的效果更加良好的药物。

测试结果如表2所示,表2显示所获得的化合物在抑制BTK和/或JAK3激酶和抗肿瘤细胞增殖中的活性效果。
表2
a:IC50:半数有效抑制浓度.b:Ramos,Raji,NAMALWA为典型B-淋巴细胞白血病细胞,BTK 激酶高度表达.
由表2的生物活性结果表明,本发明中的分子对BTK和/或JAK3激酶有较强的抑制效果,大部分化合物达到纳摩尔水平的活性级别,其中化合物I-1、I-3、I-5、I-9、 I-10、和I-12对BTK和JAK3激酶均有非常好的抑制作用,IC50值小于1nmol,与依鲁替尼和Spebrutinib相当;另外,将近一半的化合物对BTK和JAK3激酶的有效抑制浓度IC50值小于10nmol。抗细胞增殖活性结果揭示,大部分化合物对淋巴细胞白血病细胞(Ramos,Raji和NAMALWA)有非常有效的抑制作用,其中化合物I-12 对Raji细胞的有效抑制浓度达到了0.784μmol,还有化合物I-15、I-16、I-17和I-26 也显示出了预料不到的优于依鲁替尼和Spebrutinib的活性。另外,化合物I-1、I-3、 I-4、I-5、I-6、I-8、I-12、I-13、I-14、I-15、I-16、I-17、I-18、I-20、I-25和I-27显示出对NAMALWA细胞的抑制作用明显优于依鲁替尼的活性,化合物I-3、I-11、I-13、 I-14、I-15、I-16、I-17、I-18、I-24和I-26显示出对Ramos细胞的抑制作用明显优于 Spebrutinib的活性。
同时,本实验发现化合物I-12的Raji细胞活性与时间和浓度有着很大的关系,如图1所示,随着浓度的增大,细胞存活率减小,尤其72h后的Raji细胞在药物浓度达5μmol/L时,几乎不能存活,明显高于48h,由此可证明本药物属于浓度和时间依赖性药物。

细胞凋亡检测:收集各组细胞,分别加入70%的乙醇,置于4℃中过夜固定,然后加入5μL AV和5μL PI,流式细胞仪上样检测;
检测结果如图2所示,图2是化合物I-12促进B淋巴瘤细胞Raji细胞凋亡的结果。
由图2的结果表明,本发明的化合物I-12在10μmol/L的时候对促进B淋巴瘤细胞凋亡的效果明显优于依鲁替尼和Spebrutinib,而且在5μmol/L的时候,相较于依鲁替尼和Spebrutinib,化合物I-12促进B淋巴瘤细胞凋亡的效果也非常明显,因此在促进B淋巴瘤细胞凋亡方面本发明的化合物明显优于依鲁替尼和Spebrutinib。
4、活性药物毒性试验
外周血单个核细胞(Peripheral blood mononuclear cell,PBMC)包含淋巴细胞、单核细胞(monocyte)、树突状细胞和其它少量细胞(造血干细胞等)。对其进行毒性试验可以证明本发明的药物是否对正常免疫细胞具有杀伤力。目前国内外分离PBMC 的常用方法是葡聚糖-泛影葡胺密度梯度离心法,实验步骤如下:
(1)采血并稀释:静脉取血2mL,加入含ACD抗凝溶液的试管中,混匀,使血液抗凝。用PBS溶液将抗凝血稀释1倍。
(2)加样:吸取2mL淋巴细胞分层液(天津TBD)置于刻度离心管中,然后将离心管倾斜45°角,用毛细滴管将稀释的全血沿管壁缓慢加至分离液上面,应注意保持两者界面清晰。
(3)离心:在18℃~20℃下,用水平离心机以2000r/min离心20min。离心后从管底至液面分四层,依次为红细胞和粒细胞层、分层液层、单个核细胞层、血浆层。
(4)回收:用毛细吸管轻轻插到混浊带,沿管壁轻轻吸出此层细胞,移入另一支离心管中。即要吸取所有单个核细胞,又要避免吸取过多的分层液或血浆,以免混入其他细胞成分。
(5)洗涤:用PBS液洗涤细胞3次。第一次2000r/min,10min;第2~3次1500 r/min,10min,可去掉大部分混杂的血小板。
(6)将沉淀细胞悬于培养基中备用。
(7)计数铺板:调整细胞悬液浓度,以每孔2.5×105个细胞,每孔体积500μL 接种到24孔板,每组设2个复孔。
(8)细胞培养:细胞接种后,对照组用10%FBS RPMI-1640培养,实验组分别用50μL不同浓度梯度的依鲁替尼(5-20μmol/L)、活性药物(5-20μmol/L)干预, 37℃,5%CO2培养箱中继续培养(按实验要求分别培养不同时间)。
(9)染色:培养24h后加入20μL 1μg/μl AO(吖啶橙),20μL 1μg/μl PI(碘化丙啶)染色5min,倒置荧光显微镜下观察并拍照。
(10)测试结果如图3所示,图3是化合物I-12对PBMC细胞毒性数据。
由图3的结果表明,本发明的化合物I-12对PBMC细胞毒性在20μmol/L的时候与依鲁替尼相当,但在10μmol/L的时候,化合物I-12对PBMC细胞毒性明显小于依鲁替尼,因此在细胞毒性方面本发明的化合物明显优于依鲁替尼。

(1)细胞裂解液配制,细胞裂解液:PMSF=100:1备用;
(2)细胞扩大培养,铺皿给药48小时后,于4℃下裂解、12000rpm/min离心得蛋白溶液;
(3)BCA(碧云天)法测定蛋白质浓度,加入BCA后,37℃水域孵育30分钟后,在490nm波长下,用微孔板读板仪(Thermo,USA)测定吸光度,计算蛋白浓度;
(4)用无菌PBS将蛋白溶液稀释到同一浓度,再加入等体积的加样缓冲液(loading buffer),沸水中煮5-10分钟变性,-20℃储存备用;
(5)SDS-PAGE电泳分离蛋白样品,浓缩胶恒压80V,分离胶恒压120V;
(6)切出目的条带300mA恒流转膜;
(7)以5%脱脂奶粉+TTBS封闭2小时;
(8)一抗4℃杂交过夜,TTBS洗膜10分钟,洗膜三次;
(9)二抗杂交2小时,TTBS洗膜10分钟,洗膜三次;
(10)加入显影液后用蛋白凝胶成像系统显影(Bio-rad,ChemiDoc XRS+,Amercia);
(11)Image Lab 4.0分析图像,结果如图4所示,图4为化合物I-12的Western blot分析结果。
由图4的结果表明,本发明的化合物I-12能够显著抑制BTK及JAK3下游STAT3 信号通路中相关蛋白的表达,随着给药浓度的依次增大,p-BTK、p-STAT3表达水平依次下调,呈现出剂量依赖性;进一步表明了化合物I-12对BTK和JAK3有高度的选择性。该化合物具有较强的抑制B淋巴瘤细胞增殖能力,显示出比依鲁替尼和 Spebrutinib更加优良的抗BTK活性,且能够选择性地作用于JAK3激酶。
6、裸鼠移植瘤模型对体内药效学研究
裸鼠移植模型实验在SPF级条件下进行,选用5-6周雌性BALB/c小鼠(体重约为20-25g,购自北京华阜康生物科技股份有限公司),药物浓度设定60mg/kg和30 mg/kg,以依鲁替尼为参照药进行对比试验,并设定空白组,每个剂量浓度设置5只老鼠,细胞株选用Ramos细胞。细胞大规模培养后,以5×106至2×107细胞个数接种于裸鼠腋下,每只鼠100μL细胞悬液,待平均肿瘤体积长大至300-400mm3时,开始用灌胃给药(药物溶媒25%的PEG400溶液),每天给药一次,每2天测定老鼠肿瘤体积和体重,观察记录老鼠状态,连续给药12天后,将老鼠麻醉处死,剥出瘤块,进行形态学观察及称量重量。
结果如图5所示,图5是化合物I-12的体内药效学试验结果。
由图5的结果表明,本发明的化合物I-12在裸鼠移植瘤模型研究中,随着给药天数的增加,对伯基特淋巴瘤生长的抑制效果较明显,给药剂量为60mg/kg时的抑制效果较30mg/kg时更加明显,说明该化合物能够很好地抑制伯基特淋巴瘤;而且小鼠的体重无明显下降,基本保持在一定的水平,说明该化合物的毒副作用比较小,不会对机体产生损伤。结合PBMC细胞毒性方面的研究表明本发明的化合物明显优于依鲁替尼。
作为一类结构新颖的分子,由上述生物活性结果表明,本发明中的化合物体内外作用效果显著,能够很好地抑制淋巴瘤,且毒副作用较依鲁替尼和Spebrutinib小,预示此类分子具有开发成新型高效BTK和/或JAK3抑制剂的潜力,对治疗相关的肿瘤疾病尤其是伯基特氏淋巴瘤、弥漫性大B细胞淋巴瘤、滤泡性淋巴瘤或慢性淋巴细胞白血病有较大的应用价值。
以上所述仅是本发明的优先实施方式,应当指出,对于本技术领域的普通技术人员来说,在不脱离本发明技术原理的前提下,还可以做出若干改进和润饰,这些改进和润饰也应视为本发明的保护范围。
