Description
背景技术
发明领域
本发明涉及用于预防或治疗癌症的苯甲酰胺衍生物、其制备方法和包含其作为活性成分的药物组合物。
相关技术的描述
癌症的发生与各种环境因素有关,这些环境因素包括化学品、辐射和病毒,以及癌基因、肿瘤抑制基因及与凋亡和DNA修复有关的基因的变化。最近对癌症分子机制的了解使得靶向抗癌疗法成为可能,这是一种新的治疗方法。
靶向药物通常用于靶向癌细胞特征性地必须显示其有效性的分子。分子靶点是与癌细胞信号转导途径、血管生成、基质、细胞周期调节剂和凋亡相关的基因。目前,包括酪氨酸激酶抑制剂和“血管生成抑制剂”在内的“信号转导途径抑制剂”在癌症治疗中用作重要的靶向药物。
已知蛋白酪氨酸激酶在许多恶性肿瘤中起着重要作用。具体而言,表皮生长因子受体(EGFR)——erbB家族的受体酪氨酸激酶,在许多上皮细胞肿瘤中异常激活,所述上皮细胞肿瘤包括非小细胞肺癌(NSCLC)、乳腺癌、神经胶质瘤、头颈部鳞状细胞癌、结肠癌、直肠癌、头颈部癌、胃癌和前列腺癌,并且已知EGFR酪氨酸激酶的激活会造成细胞持续增殖、周围组织侵袭、远处转移、血管形成,并增加细胞存活率。
特别地,EGFR是ErbB酪氨酸激酶受体家族(EGFR,HER-2,ErbB-3,ErbB-4)之一,并且是具有细胞内结构域(包括细胞外配体结合结构域和酪氨酸激酶结构域)的跨膜酪氨酸激酶。当配体与形成同二聚体或异二聚体的受体结合时,细胞内酪氨酸激酶被激活,EGFR刺激的信号激活磷脂酰肌醇3-激酶(PI3K/AKT/mTOR、RAS/RAF/MAPK、JAK/STAT)信号传导通路(非专利文献1,Nat Rev Cancer 2007;7:169-81.Epidermal growth factor receptormutations in lung cancer)。
特别是,EGFR在超过一半的非小细胞肺癌(NSCLC)中过表达,并且许多研究已经将EGFR作为治疗靶点。已经开发出抑制EGFR酪氨酸激酶活性的EGFR TKI(酪氨酸激酶抑制剂),代表性药物包括吉非替尼(IRESSATM)、厄洛替尼(TARCEVATM)和拉帕替尼(TYKERBTM,TYVERBTM)。
另一方面,2004年,有报道称EGFR的激活突变与非小细胞肺癌(NSCLC)中吉非替尼治疗的反应相关。特别是EGFR突变主要分为致敏突变和耐药突变,外显子19缺失和外显子21的L858R点突变是最重要的致敏突变,约占85-90%,已知外显子19缺失突变对TKI更敏感。另一方面,外显子20的T790M点突变是最重要的耐药突变,已知在50%以上的获得性耐药患者中发现。
迄今为止,已鉴定的体细胞突变包括外显子19中的框内缺失或外显子20的插入,以及在表达的蛋白质中修饰单个核酸残基的点突变(例如,L858R、G719S、G719C、G719A和L861Q)。
尽管吉非替尼/厄洛替尼对具有EGFR突变的NSCLC患者具有最初临床效果,但在使用这些药物治疗期间,大多数患者最终发展晚期癌症。复发标本的早期研究识别出一种继发性EGFR突变T790M,其使得吉非替尼(zepithinib)和厄洛替尼(erlotinib)无法有效抑制EGFR激酶活性。随后的研究证明,在对吉非替尼或厄洛替尼获得耐药的患者中,大约50%的(24/48)肿瘤中发现了EGFR T790M突变。这种二次遗传修饰发生在与用激酶抑制剂治疗的患者中的‘门卫(gatekeeper)’残基和与其相关的二次抗性等位基因(例如,伊马替尼抗性CML中ABL中的T315I)相似的位置。
众所周知,EGFR突变EGFR_del19或EGFR_L858R是非小细胞肺癌和头颈癌的主要原因,并且已经开发了它们的治疗药物Iressa和Taseba,且目前用于临床试验中。然而,当这些药物用于患者时,观察到获得性抗性,导致基于药物结构的EGFR二次突变,并且还发现这是实际耐药的主要原因。当第一代EGFR抑制剂平均使用10个月时,出现获得性抗性,即位于EGFR激酶门卫中的T790M突变,第一代EGFR抑制剂无效。也就是说,发生了EGFR_del19_T790M或EGFR_L858R_T790M双突变,常规治疗药物不显示功效。
基于这些事实,出现了开发具有优异的药物功效和新结构的第2代和第3代药物的需要。
在过去10年中,已经发现对EGFR T790M双突变有作用的多种第3代新药候选物,并且临床研究正在进行,其中最先进的是跨国制药公司阿斯利康的AZD9291。然而,已报道对AZD9291的抗性发生在约10个月内,导致AZD9291药效丧失,且特别是,已报道对包括C797S在内的三重突变的抗性。
因此,需要开发对WT EGFR显示相对低的抑制作用,而对特异性活化或抗性突变形式的EGFR显示较高抑制作用的抑制剂。

[表1]
实验例1:对EGFR L858R/T790M/C797S的抑制能力的测定
为了证实本发明一方面提供的实施例1-13中制备的化合物对EGFR突变的抑制能力,进行了以下实验。
特别地,使用西斯比奥公司(Cisbio Co)的HTRF系统测量本发明化合物对EGFR突变酶的活性。作为EGFR L858R/T790M/C797S突变酶,购买了SignalChem公司提供的蛋白质,并用作酶源。
用于活性测量的分析缓冲液的组成如下:50mM Tris-HCl(pH 7.5)、100mM NaCl、7.5mM MgCl2、3mM KCl、0.01%吐温20、0.1%BSA和1mM DTT。在此,使用浓度为1mM的ATP和浓度为0.5μM的生物素标记的肽底物进行酶反应。根据以下分析反应配方对化合物的EGFR活性抑制作用进行分析。
组分1:4μl EGFR突变酶
组分2:2μl化合物溶液
组分3:4μl ATP和生物素标记的肽混合物
通过首先混合组分1和组分2,然后向其中加入组分3来引发酶反应。将混合物在37℃下反应2小时后,将10μl由链霉亲和素-XL665和由Cisbio提供的铕标记的抗磷酸酪氨酸抗体组成的测量溶液添加到酶反应溶液中,然后在室温下反应1小时。最后,使用Perkin-Elmer的Envision仪器计算615nm和665nm处的荧光值的比率,以定量测量酶活性并证实化合物的抑制能力。使用Prism程序(版本5.01,Graphpad软件公司)分析在7个化合物浓度下测量的值,并计算IC50值,即化合物抑制能力指数。
结果如表2所示。
[表2]
如表2所示,在本发明的一个方面提供的实施例1至13的化合物中,实施例1和3的化合物表现出优异的抗EGFR L858R/T790M/C797S突变的抑制能力。
实验例2:评估过表达各种EGFR突变的BaF3细胞中的抗癌活性
为了证实根据本发明的式1所示化合物作为针对EGFR野生型和突变体的变构抑制剂,评价Ba/F3细胞系中对EGFR野生型和突变体的抑制作用。此外,为了评价根据本发明的化合物与现有药物共同给药时的细胞活性,在转移性结肠直肠癌和转移性头颈鳞状癌中,单独使用西妥昔单抗或与化疗剂联合使用来评价联合给药的细胞活性。
具体而言,本发明化合物对野生型和突变型Ba/F3 EGFR细胞系的活性使用Promega的CellTiter-Glo系统进行如下测定。CellTiter-Glo分析是通过测量培养状态的细胞中存在的ATP来确认细胞活力的方法。Ba/F3 EGFR野生型(WT)和Ba/F3 EGFR del19(D)、Ba/F3 EGFR del19/T790M(DT)、Ba/F3 del19/T790M/C797S(DTC)、Ba/F3 EGFR L858R(L)、Ba/F3 EGFR L858R/T790M(LT)和Ba/F3L858R/T790M/C79 797S(LTC)突变细胞系购自科洛恩生物科技有限公司(Crown Bioscience)并使用。将Ba/F3 EGFR野生型(WT)和Ba/F3EGFR del19(D)、Ba/F3 EGFR del19/T790M(DT)、Ba/F3 del19/T790M/C797S(DTC)、Ba/F3EGFR L858R(L)、Ba/F3 EGFR L858R/T790M(LT)和Ba/F3L858R/T790M/C797S(LTC)突变细胞系在37℃、5%CO2培养箱中含有10%FBS和1%青霉素-链霉素的RPMI中培养。
根据以下分析反应配方根据每种EGFR突变体分析化合物的细胞存活抑制效果。
将BaF3细胞以2500个细胞/50μl/孔的密度等分在96孔细胞培养板中,以0、0.03、0.1、0.3和1μM浓度的50μl的式1所示化合物对其处理。将用该化合物处理的平板在37℃培养箱中反应72小时,然后根据CellTiter-Glo分析说明书在室温下放置30分钟以将平板温度维持在室温。此后,以100μl CellTiter-Glo试剂处理板的每个孔,随后在室温下振荡培养物10分钟。最后,使用光度计定量测量570nm处荧光值的比率,并确认化合物抑制细胞活力的能力。使用Prism程序(版本5.01,Graphpad软件,公司)分析化合物在5个浓度(0、0.03、0.1、0.3和1μM)下测量的值,并计算IC50值,即化合物抑制能力指数。
结果示于图1和图2中。
图1和图2示出用本发明一方面提供的实施例化合物单独或与称为EGFR拮抗剂的西妥昔单抗组合处理过表达各种EGFR突变的BaF3细胞时评价抗癌活性的结果图。
如图1和图2所示,当本发明的一个方面提供的实施例1和3的化合物与西妥昔单抗联合处理时,在具有EGFR L858R/T790M和EGFR L858R/T790M/C797S过表达的细胞中显示了协同抗癌活性。
作为参考,图1和图2的Y轴上的“仅相对于西妥昔单抗”意味着仅以西妥昔单抗单独处理时细胞活力(%)被认为是100%。
