Abstract
本发明提供了一些稠合三环脲类化合物及其盐、其组合物以及其使用方法。
Description
本发明申请是基于申请日为2014年06月27日,申请号为201480037041.6(国际申请号为PCT/CN2014/080983),发明名称为“作为Raf激酶和/或Raf激酶二聚体抑制剂的稠合三环脲类化合物”的专利申请的分案申请。
技术领域
本申请公开了稠合三环脲类化合物,包含至少一种所述稠合三环脲类化合物的药物组合物,其制备方法以及其在治疗中的用途。本申请所公开的三环脲类化合物可以用于抑制Raf激酶和/或Raf激酶二聚体并且用于治疗由其介导的病症。
背景技术
Raf/MEK/ERK通道对于细胞的存活、生长、增殖和肿瘤的形成有积极性作用(Zebisch等.,Curr Med Chem.14(5):601-623,2007;Roberts和Der,Oncogene 26(22):3291-3310,2007;Montagut和Settleman,Cancer Lett.283(2):125-134,2009)。Raf/MEK/ERK信号转导通道的激发可以在配体连接到与膜结合的受体酪氨酸激酶后产生。GTP结合的RAS被激活后,可以促进Raf家族蛋白(A-Raf,B-Raf和Raf1,以前被称作C-Raf)的活化(Wellbrock等,Nat.Rev.Mol.Cell Biol.5:875-885,2004)。据报道,Raf/MEK/ERK信号通道中各种RAS GTP酶和B-Raf激酶的突变都可结构性激活MAPK通道,从而导致细胞分化和存活量的增加(Bos,Cancer Res.49:4682-4689,1989;Hoshino等,Oncogene.18(3):813-822,1999)。例如,据报道,在很大比例的人黑色素瘤和甲状腺瘤中发现了B-Raf突变(Davies等,Nature 417:949-954,2002)(Cohen等,J.Nat.Cancer Inst.95(8):625-627,2003;Kimura等,Cancer Res.63(7):1454-1457,2003;Pollock和Meltzer,Cancer Cell2:5-7,2002)。此外,据报道,在Barret腺癌(Garnett等,Cancer Cell6:313-319,2004;Sommerer等,Oncogene 23(2):554-558,2004)、乳腺癌(Davies等,Nature 417:949-954,2002)、宫颈癌(Moreno-Bueno等,Clin.Cancer Res.12(12):365-3866,2006)、胆管癌(cholangiocarcinoma)(Tannapfel等,Gut.52(5):706-712,2003)、恶性胶质癌(Knobbe等,Acta Neuropathol.(Berl.).108(6):467-470,2004)、结肠直肠癌(Yuen等,Cancer Res.62(22):6451-6455,2002;Davies等,Nature417:949-954,2002)、胃癌(Lee等,Oncogene 22(44):6942-6945)、肺癌(Brose等,Cancer Res.62(23):6997-7000,2002)、卵巢癌(Russell和McCluggage,J.Pathol.203(2):617-619,2004;Davies等,Nature 417:949-954,2002)、胰腺癌(Ishimura等,Cancer Lett.199(2):169-173,2003)、前列腺癌(Cho等,Int.J.Cancer.119(8):1858-1862,2006)和血液癌症(Garnett和Marais,Cancer Cell 6:313-319,2004)中发现了频率较低但仍显著的B-Raf突变。这些报道表明,B-Raf是人体癌症中最经常出现突变的基因之一。基于临床前靶标确认、流行病学和成药性,B-Raf激酶可以代表一类很好的可以治疗癌症的靶标。最近,B-raf抑制剂威罗菲尼(vemurafenib)和达拉菲尼(dabrafenib)的批准证实了B-raf抑制剂在治疗B-raf突变的黑色素瘤中的效用。
除了激活Raf/MEK/ERK通路的B-raf突变,RAS GTP酶的突变或作为Raf/MEK/ERK信号传导的上游生长因子受体的畸变还导致引起癌症的该通路的持续活化。大约30%的人类肿瘤含有三种Ras基因之一的突变(Downward,Nat Rev Cancer.2003Jan;3(1):11-22);K-Ras、N-Ras和H-Ras与Ras-GRP水平升高和由此的下游信号传导通路的构成性活化相关。K-ras或N-ras突变占胰腺癌的59%,结直肠癌的39%,胆道癌的30%,非小细胞肺癌的17%,卵巢癌的15%,子宫内膜癌的15%和血癌的23%(Sanger Institut,Cosmic DatabaseJanurary 2013,cancer.sanger.ac.uk)。尽管第一代B-RAF抑制剂诸如威罗菲尼和达拉菲尼在B-RAF V600E黑色素瘤的治疗中取得了惊人的成功,但是针对具有活化的RAS突变的肿瘤无效并且在一些情况下其甚至可促进肿瘤生长(Niault等,J Cell Biol.2009 Nov 2;187(3):335-42)。临床前数据表明这可能由RAF抑制剂由通过以下方式的MAPK信号传导的反常升高引起:在活化的RAS的突变的上下文中(RAF抑制剂结合至二聚体中的一个RAF原聚体反式激活另一个原聚体),诱导B-RAF/C-RAF杂二聚体(Hatzivassiliou等,Nature.2010Mar 18;464(7287):431-5;Poulikakos等,Nature.2010Mar 18;464(7287):427-30;Heidorn等,Cell.2010 Jan 22;140(2):209-21)。还已显示具有增强的二聚化趋势的B-RAF V600E剪接变体(p61)的表达有助于对RAF抑制剂的抵抗(Poulikakos等,Nature.2011 Nov 23;480(7377):387-90)。还报道了C-RAF/B-RAF二聚体是比对应的单体或同型二聚体更好的MEK激酶(Rushworth等,Mol Cell Biol.2006Mar;26(6):2262-72)。这些发现表明RAF二聚体在疾病联系中发挥着重要作用。因此,抑制RAF二聚体的活性代表着阻断不仅由V600E突变而且由原癌RAS突变和生长因子受体的畸变触发的异常RAF信号传导的新颖的独立方法。
如早前所述,构成性二聚化p61的存在有助于对威罗菲尼的抵抗并且该剪接变体是在9位具有获得性威罗菲尼抗性的黑色素瘤患者的6位中鉴定出(Poulikakos等,Nature.2011 Nov 23;480(7377):387-90)。p61表达细胞中威罗菲尼的无效和野生型B-RAF细胞中由威罗菲尼的MAPK通路的反常活化,预示着可诱导二聚RAF的任何细胞将能够诱导对第一代B-RAF抑制剂的抵抗。实际上,这已经通过许多不同的机制进行报道,所述机制包括受体酪氨酸激酶的上调和额外的遗传突变诸如伴随的B-RAF和N-RAS突变的获得(Nazarian等,Nature.2010 Dec 16;468(7326):973-7;Tap等,Neoplasia 2010 Aug;12(8):637-49)。因此,RAF二聚体抑制剂也可能有效治疗对第一代B-RAF抑制剂诸如威罗菲尼和达拉菲尼抵抗的肿瘤。
为了评价化合物对RAF二聚体的抑制效果,重要的是首先诱导RAF蛋白的二聚体形成。p61 B-RAF剪切变体的表达通过其形成构成性p61同型二聚体的能力促使MAPK通路的活化(Poulikakos等,Nature.2011 Nov 23;480(7377):387-90),因此稳定表达p61的A375(A375-p61)还用于通过测量ERK磷酸化的IC50评价化合物对RAF二聚体的效果。由于A375-p61细胞对p61的成瘾性,对细胞增殖的半数最大效应浓度(EC50)的测量也用于该目的。最后,还报道了突变的Ras诱导RAF二聚体(Luo等,Nature.1996 Sep 12;383(6596):181-5;Weber等,Cancer Res.2001 May 1;61(9):3595-8;Garnett等,Mol Cell.2005Dec 22;20(6):963-9)。化合物在RAS突变细胞诸如Calu-6中抑制ERK磷酸化的能力用作评价化合物抑制RAF二聚体活性的能力的另一种途径。
已经讨论了Raf激酶抑制剂在破坏肿瘤细胞生长中的用途,以及由此在治疗癌症例如黑色素瘤、结肠直肠癌(包括大肠结肠癌)、组织细胞性淋巴瘤、肺腺癌、小细胞肺癌、胰腺癌和乳腺癌(Crump,Current Pharmaceutical Design 8:2243-2248,2002;Sebastien等,Current Pharmaceutical Design 8:2249-2253,2002)中,和/或在治疗或预防与由缺血事件造成的神经元变性相关的病症,包括在心搏停止后的脑缺血、中风和多发梗塞性痴呆中的用途。还讨论了Raf激酶抑制剂在脑缺血性事件后及在多囊性肾病(Nagao等,KidneyInt.63(2):427-437,2003)中的用途,所述脑缺血性事件为诸如来自于头部受伤、外科手术和/或分娩期的那些脑缺血性事件(York等,Mol.and Cell.Biol.20(21):8069-8083,2000;Chin等,Neurochem.90:595-608,2004)。
此外,某些高增殖性病症的特征是Raf激酶功能的过度活化,例如,这种活化来自于蛋白质的突变或过度表达。因此,Raf激酶的抑制剂可用于高增殖性病症诸如癌症的治疗。
