Definitions

  • the present invention relates to a pyridylaminopyrimidine derivative and a pharmaceutically acceptable salt thereof for selectively inhibiting a mutant form of epidermal growth factor receptor (EGFR) activity, and a process for the preparation thereof, comprising the derivative and pharmaceutically acceptable thereof
  • EGFR epidermal growth factor receptor
  • a pharmaceutical composition that accepts a salt, and the derivative and pharmaceutically acceptable salt thereof, in the treatment of a disease mediated by certain mutant forms of EGFR, and a medicament for the treatment of a disease mediated by certain mutant forms of EGFR Aspect of the application.
  • Cancer is considered to be a disease of the intracellular signaling system or signaling mechanism.
  • the most common cause of cancer is a series of defects, which can be protein defects (when they are mutated), or defects in the regulation of the amount of protein in the cell, resulting in overproduction or underproduction of the protein.
  • Mutations in cell surface receptors can cause kinases to be activated in the absence of ligands and deliver signals that are not actually present.
  • many receptor tyrosine kinases can be overexpressed on the cell surface, resulting in an over-strong response to weak signals.
  • Epidermal growth factor receptor has been identified as a critical driver of cell growth and proliferation.
  • the epidermal growth factor receptor family consists of EGFR (Erb-B1), Erb-B2 (HER-2/neu), Erb-B3 and Erb-B4.
  • Epidermal growth factor receptors are involved in disease progression in most cancers, such as lung cancer, colon cancer, breast cancer, and the like. Overexpression and mutation of EGFR have been clearly identified as major risk factors for breast cancer with poor prognosis.
  • all four members of the receptor family can be polymerized with heterologous dimers with other members of the family to form a signaling complex if more than one member of the family is overexpressed in a malignant tumor Can lead to coordinated signaling.
  • EGFR belongs to the family of protein tyrosine kinases (PTKs), a class of enzymes that catalyze the transfer of a phosphate group from adenosine triphosphate (ATP) to a tyrosine residue located on a protein substrate.
  • PTKs protein tyrosine kinases
  • ATP adenosine triphosphate
  • Protein tyrosine kinases play a role in normal cell growth. Overexpression or mutation of EGFR results in activation of the receptor in the absence of a ligand, phosphorylating certain proteins, and producing a signal for cell division. Therefore, EGFR, through the action of its own tyrosine kinase, leads to excessive amplification of weak signals, causing excessive proliferation of cells.
  • PTK inhibitors as potential anti-cancer therapeutics have received much attention.
  • Representative representatives of marketed EGFR reversible inhibitors include Gefitinib, Erlotinib, and Lapatinib, which inhibit EGFR wild-type and activating mutations (eg, exon 19 deletion)
  • Activating mutations, or L858R activating mutations are structured as follows for the treatment of non-small cell lung cancer (NSCLC) and breast cancer, respectively.
  • NSCLC non-small cell lung cancer
  • Clinical studies have shown that gefitinib and erlotinib have a good therapeutic effect on NSCLC patients with EGFR deletion of exon 19 or L858R point mutation.
  • their limitation is that patients develop resistance after receiving treatment, which limits the further clinical application of such inhibitors.
  • T790M is located at the entrance of the EGFR-ATP binding pocket, and the size of its side chain directly affects the binding ability of EGFR and ATP.
  • the T790M mutation spatially blocks the action of the EGFR inhibitor with the ATP binding site, increases the affinity of EGFR for ATP, and renders the cell resistant to EGFR inhibitors.
  • Irreversible EGFR inhibitors have significant advantages over reversible EGFR inhibitors. Irreversible EGFR inhibitors can inhibit EGFR for long periods of time and are only limited by the normal rate of receptor recombination (also known as recovery). Studies have found that irreversible EGFR inhibitors can covalently bind to the upper cysteine residue of EGFR (Cys797) through the Michael addition reaction, which can expand the irreversible EGFR inhibitor and ATP binding site, so as to overcome to some extent Resistance to T790M mutations (Li D et al, Oncogene, 27: 4702-4711, 2008).
  • the currently available irreversible EGFR inhibitors are BIBW-2992 (Afatinib), including HEKI-272 (Neratinib), EKB-569 (Pelitinib), PF00299804 (Dacomitinib), etc.
  • the structure is as follows.
  • quinazoline compounds The main structural types of reversible or irreversible EGFR inhibitors listed or under development are quinazoline compounds.
  • quinazoline EGFR inhibitors have been reported to be ATP competitive inhibitors of wild-type EGFR, resulting in some vice- The reaction takes place.
  • the researchers reported a class of pyrimidine-specific irreversible EGFR inhibitors that act on EGFR T790M, and the structure is shown below.
  • the inhibitory activity of such pyrimidine compounds on EGFR T790M is increased by 30-100 fold, and the inhibition of wild-type EGFR is lived.
  • the sex was reduced by a factor of 100 (Wenjun Zhou et al, Nature, 462: 1070-1074, 2009), but lately this pyrimidine compound did not enter clinical studies.
  • CO1686 Another series of pyrimidine compounds are disclosed in International Patent No. WO 2012/061299 A1 to Avila Therapeutics, having the structural formula below, wherein the representative compound is CO1686. According to reports in the literature, CO1686 can selectively act on EGFR-activated mutations and T790M-resistant mutations, but has a weaker inhibitory effect on wild-type EGFR (Walter A O, Sjin R T T, Haringsma H J, et al. [J] .Cancer discovery, 2013, 3 (12): 1404-1415.). Currently ready to enter the clinical phase II phase.
  • a series of pyrimidine compounds are also disclosed in the international patent WO 2013/014448 A1 to ASTRAZENECA AB.
  • the structural formula is as follows, wherein the representative compound is AZD9291, which has more EGFR-activated mutations and T790M-resistant mutations than wild-type EGFR. Good inhibition is currently in the phase I clinical stage.
  • the inhibitory activity of the mutation was significantly higher than that of wild-type EGFR (WT EGFR), with good selectivity, low toxicity and good safety. It is expected that such inhibitors will have good curative effect and are expected to overcome the problem of drug resistance and side effects, and have good development prospects.

本发明涉及一种选择性抑制突变形态的表皮生长因子受体(EGFR)活性的吡啶胺基嘧啶衍生物及其药学上可接受的盐以及其制备方法,包含所述衍生物及其药学上可接受盐的药物组合物,以及所述衍生物及其药学上可接受盐在治疗由某些突变形态的EGFR介导的疾病以及制备用于治疗由某些突变形态的EGFR介导的疾病的药物方面的应用。
背景技术
癌症被认为是细胞内信号传导系统或信号传导机制的疾病。癌症的最常见病因是一系列的缺损,所述缺损可以是蛋白质的缺损(当其突变时),或者是对细胞内蛋白质的量的调节的缺损,从而使蛋白质过度产生或产生不足。细胞表面受体的突变(该突变通常通过酪氨酸激酶将信号传递到细胞内)可导致激酶在缺乏配体的条件下被激活,并传递事实上并不存在的信号。或者,许多受体酪氨酸激酶可在细胞表面过度表达,导致对弱信号的过强响应。
表皮生长因子受体(EGFR)被确认为是在细胞生长和增值过程中至关重要的驱动因素。表皮生长因子受体家族由EGFR(Erb-B1)、Erb-B2(HER-2/neu)、Erb-B3和Erb-B4组成。表皮生长因子受体与大部分癌症的疾病进程有关,如肺癌、结肠癌、乳腺癌等。EGFR的过度表达和突变已被明确证实是预后不好的乳腺癌的主要危险因素。此外,已证实该受体家族的所有四个成员均可与该家族的其他成员聚合为异源二聚体,形成信号传导复合物,如果该家族中有一个以上的成员在恶性肿瘤中过度表达,便可导致协同的信号传导作用。
EGFR属于蛋白酪氨酸激酶(PTK)家族,蛋白酪氨酸激酶是一类将磷酸基团从三磷酸腺苷(ATP)催化转移到位于蛋白质底物的酪氨酸残基的酶。蛋白酪氨酸激酶在正常细胞生长中起作用。EGFR的过度表达或突变,导致受体在缺乏配体的条件下被激活,使某些蛋白发生磷酸化,产生了细胞分裂的信号。因此,EGFR通过自身酪氨酸激酶的作用,导致了弱信号的过度放大,引起了细胞的过量增值。
作为潜在的抗癌治疗药物的特异性PTK抑制剂备受关注。目前已经 上市的EGFR可逆性抑制剂的典型代表包括吉非替尼(Gefitinib)、埃罗替尼(Erlotinib)、拉帕替尼(Lapatinib),抑制EGFR野生型和激活型突变(例如19号外显子缺失激活突变、或L858R激活突变),其结构如下,分别用于非小细胞肺癌(NSCLC)和乳腺癌的治疗。临床研究证明吉非替尼、埃罗替尼对EGFR发生19号外显子缺失或L858R点突变的NSCLC患者有良好的治疗作用。然而,它们的局限在于患者在接受治疗后产生耐药,使得此类抑制剂在临床上的进一步应用受到限制。研究表明,50%的吉非替尼、埃罗替尼治疗后耐药性的产生与EGFR发生二次突变(T790M)相关(PaoW.等,Plos Med.,2:1-11,2005),可逆抑制剂失去疗效。
Figure PCTCN2015000540-appb-000001
T790M位于EGFR与ATP结合口袋的入口,其边链的大小直接影响EGFR和ATP的结合能力。T790M突变在空间上阻碍EGFR抑制剂与ATP结合位点的作用,增加EGFR对ATP的亲和力,使细胞对EGFR抑制剂产生耐药。
与可逆性EGFR抑制剂相比,不可逆EGFR抑制剂具有非常突出的优点。不可逆EGFR抑制剂可长时间的抑制EGFR,只受到受体再结合(也称为回复)的正常速率的限制。有研究发现,不可逆EGFR抑制剂可通过麦克尔加成反应与EGFR上半胱氨酸残基(Cys797)共价结合,使不可逆EGFR抑制剂与ATP结合位点扩大,从而能在一定程度上克服T790M突变引起的耐药性(Li D等,Oncogene,27:4702-4711,2008)。目前已上市的不可逆EGFR抑制剂有BIBW-2992(Afatinib),在研的包括HKI-272(Neratinib)、EKB-569(Pelitinib)、PF00299804(Dacomitinib)等,其结 构如下。
Figure PCTCN2015000540-appb-000002
然而,这类能够抑制EGFR T790M的不可逆EGFR抑制剂,对野生型EGFR的抑制作用也很大,带来较大的毒副作用,如腹泻、皮疹、恶心、厌食,虚弱无力(Besse,B.等Eur.J.Cancer Suppl.,6,64,abstr.203,2008;Janne,P.A.等,J.Clin.Oncol.,25:3936-3944,2007),因此虽然据文献报道,在临床前BIBW2992(Afatinib)和PF00299804(Dacomitinib)显示具有显著的抗肿瘤活性,能抑制EGFR和EGFR T790M的活性,但在临床过程中因为这些不良反应的发生,最终限制了其临床给药剂量及有效血药浓度,使得BIBW2992(Afatinib)和PF00299804(Dacomitinib)在克服T790M耐药突变方面未能取得令人瞩目的进展(Katakami N,Atagi S,Goto K,et al.[J].Journal of Clinical Oncology,2013,31(27):3335-3341.;

上述上市或在研的可逆或不可逆EGFR抑制剂主要结构类型为喹唑啉类化合物,目前已报道的喹唑啉类EGFR抑制剂均为野生型EGFR的ATP竞争性抑制剂,由此导致一些副反应的发生。2009年,研究人员报道了一类嘧啶类的特异性作用于EGFR T790M的不可逆EGFR抑制剂,结构如下所示。与现有的苯胺喹唑啉EGFR抑制剂相比,此类嘧啶化合物对EGFR T790M的抑制活性提高了30-100倍,对野生型EGFR的抑制活 性降低了100倍(Wenjun Zhou等,Nature,462:1070-1074,2009),但后期该类嘧啶化合物未进入临床研究。

Avila Therapeutics申请的国际专利WO 2012/061299 A1中公开了另一系列嘧啶类化合物,结构式如下,其中代表性的化合物为CO1686。据文献报道,CO1686能够选择性作用于EGFR激活型突变和T790M耐药型突变,而对野生型EGFR抑制作用较弱(Walter A O,Sjin R T T,Haringsma H J,et al.[J].Cancer discovery,2013,3(12):1404-1415.)。目前准备进入临床II期阶段。

ASTRAZENECA AB申请的国际专利WO 2013/014448 A1中也公开了一系列嘧啶类化合物,结构式如下,其中代表性的化合物为AZD9291,相对于野生型EGFR对EGFR激活型突变和T790M耐药型突变有更好的抑制作用,目前处在I期临床阶段。
Figure PCTCN2015000540-appb-000006
为克服临床中常见的EGFR耐药性突变(例如T790M突变)以及现有EGFR抑制剂的毒副作用问题,即开发更多的对某些激活突变体和耐药 型突变体形式的EGFR显示较高的抑制同时对野生型EGFR显示相对较低的抑制的小分子抑制剂已经是当前抗肿瘤领域的迫切需要。本发明人在研究EGFR抑制剂的过程中,惊喜地发现了一类吡啶胺基嘧啶衍生物,对EGFR激活型突变(如19号外显子缺失激活突变、或L858R激活突变)和T790M耐药型突变的抑制活性显著高于对野生型EGFR(WT EGFR)的抑制活性,有很好的选择性,并且毒副作用较低,安全性好。预期此类抑制剂将会有好的疗效,有望克服耐药性问题及毒副作用问题,具有良好的开发前景。

实验动物:BALB/c nude裸鼠,15只,雄性15只,雌性0只,6周,18-20g,购自上海动物实验中心。
设3个实验组,分别为:0.5%羧甲基纤维素钠溶剂对照组,实施例3化合物25mg/kg组和AZD9291 25mg/kg组。
实验方法:人肺癌H1975细胞株(5×106个/只)接种于实验小鼠于右侧背部皮下,每只小鼠接种量是0.1ml,定期观察肿瘤生长情况,待肿瘤生长至平均(100-150)mm3时根据肿瘤大小和小鼠体重随机分组。实施例3化合物和AZD9291各自按25mg/kg灌胃给药,溶剂对照组灌胃给予等量溶剂,每天给药一次,连续12天。整个实验过程中,每周测量两次小鼠的体重和肿瘤的大小,观察是否出现毒性反应。
肿瘤大小计算公式:肿瘤体积(mm3)=0.5×(肿瘤长径×肿瘤短径2)。
三个实验组肿瘤体积变化曲线见附图1,小鼠体重变化曲线见附图2。结果表明本发明化合物对人肺癌H1975裸小鼠皮下移植瘤的生长具有良好的抑制作用,并且对裸小鼠体重影响较小,显示出较好的安全性。
