Abstract
本发明涉及式(I)的化合物及其药物学上可接受的盐、前药和溶剂化物,这类化合物可用于治疗哺乳动物中癌症和炎症。本发明还公开了式(I)化合物的制备方法以及包含所述化合物的药物组合物。
Description
技术领域
本发明涉及某些氟代杂环化合物及其药学上可接受的盐,其可用于由某些变异形态的表皮生长因子受体(例如L858R激活突变体、Exon19缺失激活突变体、和T790M抗性突变体)所介导疾病或病况的治疗和预防。此类化合物及其盐可用于很多不同的癌症的治疗或预防。本发明还涉及包含所述化合物及其盐的药物组合物、所述化合物的制备中的中间体、和涉及利用所述化合物及其盐治疗各种不同形式的EGFR介导的疾病的方法。
背景技术
EGFR是erbB受体家族的跨膜蛋白酪氨酸激酶成员。当与生长因子配体(例如表皮生长因子(EGF))结合时,受体可以与附加的EGFR分子发生同源二聚,或者与另一家族成员(例如erbB2(HER2)、erbB3(HER3)、或者erbB4(HER4))发生异源二聚。
erbB受体的同源二聚和/或异源二聚导致胞内域中关键酪氨酸残基的磷酸化,并且导致对参与细胞增殖和生存的许多细胞内信号传导通路的刺激。erbB家族信号传导的失调促进增殖、侵入、转移、血管生成、和肿瘤细胞生存,并且已在许多人类癌症(包括肺癌、头颈部癌和乳腺癌)中得到描述。
因此,erbB家族代表抗癌药物开发的合理靶点,靶向EGFR或erbB2的许多药剂现在是临床上可用的,包括吉非替尼(IRESSATM)、厄洛替尼(TARCEVATM)、拉帕替尼(TYKERBTM,TYVERBTM)。New England Journal of medicine(2008)第358期,1160-74和Bi℃ hemicaland biophysical Research communication(2004)Vol.319,1-11中提供了对erbB受体信号传导及其在肿瘤发生中的参与的详细论述。
于2004年报道的(Science[2004]第304期,1497-500和New England Journal ofmedicine[2004]第350期,2129-39)在非小细胞肺癌(NSCLC)中EGFR的激活突变与对吉非替尼治疗的反应有关。最普遍的EGFR激活突变(L858R和dele746_A750)导致相对于野生型(WT)EGFR而言,对小分子酪氨酸激酶抑制剂(如吉非替尼和厄洛替尼)的亲和力增加、以及对上磷酸腺苷(ATP)亲和力下降。最后,产生对吉非替尼或厄洛替尼治疗的获得性抗性,例如看门残基T790M的突变,据报道在50%的临床耐药性患者中检测到该突变,该突变不被认为是在空间上阻碍吉非替尼或厄洛替尼与EGFR的结合,仅将对ATP的亲和力改变到相当于WT EGFR的水平。
鉴于这种突变在靶向EGFR的现有疗法的抗性中的重要性。我们认为可以抑制包含看门基因突变的EGFR的药物在癌症的治疗中特别有用。
相对于激活突变体形式的EGFR(例如L858R EGFR突变体、或者delE746_A750突变体或Exon19缺失EGFR突变体)和/或抗性突变体形式的EGFR(例如T790M EGFR突变体),对于可表现出对WT EGFR的有利效能特性、和/或相对其它酶受体的选择性化合物仍然存在着需求,所述选择性使得这些化合物特别有希望被开发成治疗剂。就这点而言,对于对某些激活或抗性突变体形式的EGFR显示较高的抑制同时对WT EGFR显示相对较低的抑制的化合物存在需求。由于与野生型EGFR抑制相关的毒理学减小,因而预期此类化合物可以更适于用作治疗剂,特别是用于癌症治疗。已知此类毒理学在人体中表现为皮疹和/或腹泻。
本发明申请人发现相对于若干EGFR突变体形式一种或多种氟代杂环化合物具有高效能,同时显示对WTEGFR相对较低的抑制。与其它已知的EGFR/EGFR突变体抑制剂相比,本发明的化合物也可显示有利的物理性质(例如,较高的水溶解度、渗透性和/或较低的血浆蛋白结合)和/或有利的毒性特征(例如降低的hERG阻断倾向)和/或有利的代谢特征。因此,此类化合物在例如癌症治疗中牵连有EGFR和/或EGFR的激活突变和/或EGFR的抗性突变的疾病状况的治疗中尤其有用。
