Abstract

Description
技术领域
本发明描述了对蛋白激酶具有抑制活性的新型炔类衍生物及其药物组合物,其用于预防或治疗与异常细胞生长相关的疾病。
背景技术
蛋白激酶是催化蛋白质的丝氨酸、苏氨酸和酪氨酸部分中用于羟基磷酸化的一组酶。它们在诱导细胞生长、分化和增殖的生长因子信号传导中起着非常重要的作用。人类蛋白激酶可以分为酪氨酸蛋白激酶和丝氨酸/苏氨酸蛋白激酶。酪氨酸蛋白激酶可以进一步分为受体激酶和细胞质/非受体激酶(Manning等人,Science,2002,298,1912)。受体酪氨酸激酶具有与生长因子相互作用的细胞表面区域,以及使酪氨酸部分进行里磷酸化的细胞质区域。这样,生长因子可以与生长因子受体位点结合,从而引发受体酪氨酸激酶的聚合和细胞质内酪氨酸部分的自磷酸化。随后,蛋白质亚家族的相继磷酸化作为信号传导过程继续进行,导致转录因子过表达并最终成为癌症。特定蛋白激酶的突变或过表达可能会影响正常细胞的信号传导,从而导致身体的稳态失衡。例如,连续信号传导可导致癌症、炎症、代谢综合征和中枢神经系统(CNS)疾病。
慢性粒细胞性白血病(CML)患者中存在bcr/abl融合基因,其由染色体22上的断裂点簇集群区(breakpoint cluster region,bcr)与染色体9上的c-abl原癌基因重构而成。所述含有bcr/abl基因的染色体被称为费城染色体(Nowell,J.Natl.Cancer Inst.,1960;25:85)。在bcr/abl融合基因中,bcr基因部分含有低聚区域,abl基因部分包含酪氨酸区域。有报道,bcr/abl基因的三个主要部分(p190、p210和p230kDa)由bcr基因的断裂点决定。格列卫(甲磺酸伊马替尼,STI-571)是由诺瓦提斯公司开发并于2002年公布的第一个靶向抗癌试剂。格列卫通过抑制abl酪氨酸激酶能够选择性地抑制bcr/abl。格列卫通常作为CML的标准治疗药物,但是对格列卫的获得性耐药性逐渐成为严重的问题。导致获得性耐药的机制有多种,包括bcr/abl基因扩增、bcr/abl基因减少,以及bcr/abl基因点突变。其中诱发获得性格列卫-耐药性的最重要的因素是abl激酶区域内的T315I-bcr/abl靶基因点突变。人们正在努力进行多种克服格列卫耐药性的工作。近期发布的药物例如尼罗替尼和达沙替尼有效地抑制由格列卫耐药引起的abl激酶区域的许多点突变。然而,尼罗替尼和达沙替尼无法抑制T315I-bcr/abl突变种。因此,人们在大量尝试开发一种抑制T315I-bcr/abl突变的药物。血管内皮生长因子(VEGF)调节内皮细胞的大量生物过程,如细胞存活、增殖、分化、血管生成和迁移。VEGF主要由血管内皮的、造血的基质细胞在对低氧响应时或受到生长因子(如TGF、PDGF或白介素)刺激时产的。VEGF结合至它们的高亲和性特异性受体VEGFR上(VEGFR-1、-2和-3)。每种VEGF亚型结合于这些受体的特定亚单位上,致使形成受体同质二聚体和异质二聚体,其激活分散的信号通路并执行其生物功能,如血管生成[Cébe-Suarez S, A,Ballmer-Hofer K.Cell Mol Life Sci.2006Mar;63(5):601-15]。血管生成为肿瘤提供营养、氧以及癌细胞扩散的通道。因此,血管生成对于癌细胞的增殖和扩散非常重要。血管生成在正常人体内通过血管生成刺激与抑制共同调节来平衡。然而,在失衡的癌细胞内,VEGFR被对血管内皮细胞具有巨大影响的生长因子(例如VEGF)激活[Ann Hoeben,Bart Landuyt,Martin S.Highley,Hans Wildiers,Allan T.Van Oosterom和Ernst A.De Bruijn.Pharmacological Reviews.2004卷56(4):549-580]。各种VEGF受体酪氨酸激酶抑制剂(合成的小分子)正在被开发,这些小分子抑制剂的大部分能被用于实体肿瘤,抑制仅在癌细胞中激活的血管生成,并且具有巨大的药物作用和相当低的副作用。

实施例36中所得化合物36的光学异构体的分离,及其绝对构型的确定
将实施例36中所得外消旋产物(5.0g)经手性柱(CHIRALCEL AS-H,0.46cm I.D.×25cm L)以SFC(超临界流体色谱)法分离(见图1)。分别在保留时间为16.817min的峰1(以下也称为HAP-71-P1,2.8257g,)和保留时间为21.378min的峰2(以下也称为HAP-71-P2,2.5913g, )收集产物。
根据下文描述的方法进行以上分离的产物的绝对构型确认。
步骤1.(S)-1-(1,1-二氟-2,3-二氢-6-硝基-1H-茚满-3-基)-4-甲基哌嗪的制备(以下称为HA-6-13-1)
在室温下,向10mL甲醇中的1-(1,1-二氟-2,3-二氢-6-硝基-1H-茚满-3-基)-4-甲基哌嗪(1g,4mmol)外消旋混合物中加入D-樟脑-10-磺酸(1.84g,8mmol),然后加入5mL异丙醇。将混合物回流并冷却至室温。将溶液在-20℃放置5天,过滤收集所得固体。将固体在甲醇:异丙醇=1:2的溶液中重结晶四次,得到220mg无色固体。将所述固体溶解于10mLCH2Cl2,并向其中加入5mL 1M的NaOH溶液,将混合物搅拌0.5h。分离出水层,并进一步用CH2Cl2(2×10mL)萃取。合并有机层,用卤水洗涤,以Na2SO4干燥,蒸发得到产物55mg(以下称为HA-6-13-1)。
如下表所示,化合物1-(1,1-二氟-2,3-二氢-6-硝基-1H-茚满-3-基)-4-甲基哌嗪理论上具有两种光学异构体,以下分别称为ZDF2a和ZDF2b。
通过对比化合物HA-6-13-1的实验ECD谱和光学异构体ZDF2a及ZDF2b相应的计算ECD谱,确定以上制备的化合物HA-6-13-1的绝对构型。进行MMFF94(默克分子力场94)构象检索,随后使用密度泛函理论以B3LYP/6-31G(d)(Becke 3-Lee-Yang-Parr交换-关联泛函)法再优化,得到11个最低能量的构象异构体。然后通过11个构象异构体ECD谱的玻尔兹曼权重生成对映异构体ZDF2a和ZDF2b的整体ECD谱。HA-6-13-1记录的ECD谱与ZDF2b的计算ECD曲线吻合,但与ZDF2a的相反(见图2)。因此,推断化合物HA-6-13-1具有S绝对构型。
步骤2.(S)-N-(1,1-二氟-2,3-二氢-3-(4-甲基哌嗪-1-基)-1H-茚满-6-基)-3-碘-4-甲基苯甲酰胺的制备
采用类似于实施例36步骤7中描述的方法,由3-碘-4-甲基苯甲酸和(S)-1-(1,1-二氟-2,3-二氢-6-氨基-1H-茚满-3-基)-4-甲基哌嗪(由HA-6-13-1制备)合成标题化合物。得到为浅黄色固体的产品。LCMS:m/z[M+H]+512.1088.
步骤3.(S)-N-(1,1-二氟-2,3-二氢-3-(4-甲基哌嗪-1-基)-1H-茚满-6-基)-3-(2-(咪唑并[1,2-b]哒嗪-3-基)乙炔基)-4-甲基苯甲酰胺(对应于化合物36-(S))的制备
采用类似于实施例1中描述的方法,由3-乙炔基咪唑并[1,2-b]哒嗪和(S)-N-(1,1-二氟-2,3-二氢-3-(4-甲基哌嗪-1-基)-1H-茚满-6-基)-3-碘-4-甲基-苯甲酰胺合成标题化合物。得到为浅黄色固体的产品。HRMS(ESI-TOF+):m/z[M+2H]+2C30H30F2N6O的计算值:264.1219;测定值:264.1216.
以上制备的化合物记录的ECD与以上分离的产物HAP-71-p1(峰1收集的)的曲线吻合,但与产物HAP-71-p2(峰2收集的)的相反(见图3)。因此,推断HAP-71-p1具有S绝对构型。
为了进一步确认产物HAP-71-p1(峰1收集的)与以上制备的(S)-N-(1,1-二氟-2,3-二氢-3-(4-甲基哌嗪-1-基)-1H-茚满-6-基)-3-(2-(咪唑并[1,2-b]哒嗪-3-基)乙炔基)-4-甲基苯甲酰胺(化合物36-(S))具有相同的绝对构型,使制备的化合物36-(S)通过手性柱(CHIRALCELAS-H,0.46cm I.D.×25cm L),手性柱分析结果与ECD谱一致(请见图4)。
因此,HAP-71-P2的绝对构型是R,如下式所示。

生物学试验
本发明化合物的活性可以使用以下试验评估。
细胞死亡试验评估
细胞死亡试验方法:
实验1:
以1.5×105个细胞/ml/孔的量将K562细胞接种在24孔板上,后用100nM剂量的AP-24534和测试化合物将细胞处理48小时。通过在4000rpm离心4min收集细胞,然后用150ulPBS重新悬浮细胞。活细胞通过台盼蓝方法用TC10计数。
结果:
表1 在100nM下杀灭K562细胞的化合物活性(%活细胞相对于对照)
*AP-24534的结构如下(J.Med.Chem.,2010,53,4701-4719),
实验2:
将K562细胞(2×105个细胞/ml)接种在24孔细胞培养板上并用DMSO或试剂处理。在DMSO或试剂存在下处理48h后,通过在500g离心5分钟收集细胞,然后将细胞重新悬浮在合适体积的PBS中。将10uL细胞悬浮液与10uL台盼蓝溶液混合,活细胞通过TC10(Bio-Rad,Richmond,CA)计数。
结果:
表2 一些代表性化合物IC50值
化合物 | IC<sub>50</sub>(nM) |
3 | 3 |
12 | 4 |
13 | 11 |
23 | 16 |
30 | 3.6 |
36 | 0.87 |
37 | 3.4 |
如上述实验2所示,将IC50值大于0nM而小于20nM的本发明化合物定为“A”级。将IC50值大于等于20nM而小于1000nM的本发明化合物定为“B”级。
实验3:
方法:
本研究评估纯光学异构体体外对人白血病细胞活性的影响。使用帕纳替尼作为阳性对照。本研究中使用两种BCR-ABL-阳性人白血病细胞系K562和KU812。此外,本研究还使用了表达天然的BCR-ABL或T315I-BCR-ABL的Ba/F3细胞转染子,其活性取决于异位表达BCR-ABL。使用表达BCR-ABLT315I的Ba/F3细胞测试待测试化合物对导致伊马替尼(格列卫)抗药性的点突变BCR-ABLT315I的有效性。采用U937和JURKAT(两种BCR-ABL-阴性人白血病细胞系)测试待测试化合物的选择性。
将细胞接种于24孔板,在相应浓度下用药物处理。用96-孔板酶标仪使用基于MTT(3-(4,5-二甲基噻唑-2-基)-2,5-二苯基溴化四唑)的比色检测测量细胞活性。使用两组独立实验的平均值计算IC50值。
结论:BCR-ABL抑制剂对BCR-ABL-阳性和-阴性人白血病细胞系和一组Ba/F3细胞转染子细胞活性的影响(IC50为平均值±S.E.M,nM)。
结果显示,无论是外消旋化合物还是具有绝对构型R或者S的纯异构体,均对白血病细胞或者表达天然BCR-ABL的BaF3细胞显示活性。特别是,化合物36-(S)和38-(S)与参比化合物帕纳替尼相比,对白血病细胞或者表达天然BCR-ABL的BaF3细胞的活性相似。而对于表达BCR-ABLT315I的BaF3细胞,化合物36-(S)和38-(S)比参比化合物帕纳替尼表现更好,意味着这两种化合物在治疗对伊马替尼(第一代酪氨酸激酶抑制剂)抗药的患者时可能更有效。此外,化合物36-(S)和38-(S)在BCR-ABL-阴性人白血病细胞系U937和JURKAT上功效要差。这意味着,化合物36-(S)和38-(S)在临床使用时可能对BCR-ABL具有更好的选择性和更小的副作用。
表3 BCR-ABL抑制剂对BCR-ABL-阳性和-阴性人白血病细胞系和Ba/F3细胞转染子细胞活性的影响(IC50为平均值±S.E.M,nM)
实验4:
方法
将含有BCR-ABL的T315I突变异构体的鼠科祖B细胞系Ba/F3皮下注射至NODSCID小鼠(NOD.CB17-Prkdcscid/J)。给小鼠口服测试化合物14天。使用帕纳替尼作为阳性药物,剂量为10或20mg/kg/天;化合物36-(S)剂量为10或20mg/kg/天;化合物38-(S)剂量为5mg/kg/天。每周测量三次小鼠两个维度的肿瘤体积和体重(体积=L×W2×0.5)。
结果:
药物的TGI(肿瘤生长抑制)为:帕纳替尼20mg/kg/天,94%;帕纳替尼10mg/kg/天,75%;化合物36-(S)20mg/kg/天,108%;化合物36-(S)10mg/kg/天,105%;化合物38-(S)5mg/kg/天,81%。TGI大于100%表示用药物治疗14天后的肿瘤小于它们的原始尺寸。小鼠重量在以上述剂量治疗期间未明显改变。结果也示出于图8的A和B中。
从动物实验的结果,我们可以得出:剂量为10mg/kg/天的化合物36-(S)比剂量为20mg/kg/天的帕纳替尼活性更佳。剂量为5mg/kg/天的化合物38-(S)比剂量为10mg/kg/天的帕纳替尼活性更佳。总的来说,在BaF3/BCR-ABLT315I小鼠异种移植模型中,化合物36-(S)和38-(S)比帕纳替尼的活性更好。
以上的结果表明,本发明的化合物,优选由式VIII表示的外消旋化合物或者光学异构体,及更优选由式VIII表示的具有S绝对构型的化合物,对抑制蛋白激酶(例如Bcr-Abl、c-Kit、c-Src、FGFR1、FLT3、LYN、PDGFR,特别是Bcr-Able(T315I))、抑制或治疗癌症(例如慢性粒细胞白血病(CML)、急性淋巴性白血病(ALL)、非小细胞肺癌(NSCLC)、胃肠基质肿瘤(GIST)、急性髓性白血病(AML),特别是慢性髓性白血病(CML))和抑制和/或治疗炎症(例如哮喘、类风湿关节炎)具有良好的功效。
