Definitions

  • the present invention relates to the field of medicine.
  • it relates to arylphosphonic compounds as protein kinase inhibitors.
  • Protein kinases represent a large family of proteins that play important roles in the regulation of a variety of cellular processes and in the maintenance control of cellular functions. They include proliferation, apoptosis, cytoskeletal rearrangement, differentiation, development, immune response, nervous system function and conduction. In addition, many diseases and/or disorders are associated with aberrant, abnormal or dysregulated activity of one or more kinases.
  • Lung cancer is one of the most common malignant tumors, and it is generally divided into two categories: Small Cell Lung Cancer (SCLC) and Non-Small Cell Lung Cancer (NSCLC). Lung cancer ranks first in the world. Among them, non-small cell lung cancer (NSCLC) accounts for more than 80% of all lung cancers, which is a serious threat to human health (Chinese Journal of Lung Cancer [J], 2012 Feb 20;15(2):106–111).
  • EGFR epidermal growth factor receptor
  • EGFR epidermal growth factor receptor
  • the mutation and abnormal activation of EGFR are closely related to the occurrence, development, malignancy, and metastasis of various tumors, such as non-small cell lung cancer, breast cancer, and esophageal cancer.
  • Most non-small-cell lung cancer (NSCLC) patients have overexpression of EGFR.
  • Asian non-small cell lung cancer populations especially the Chinese population
  • about 40-50% are EGFR mutations. Inhibition of EGFR can significantly improve the survival of NSCLC patients.
  • EGFR Common mutations of EGFR can be divided into two categories, one is drug-sensitive mutation, that is, anti-tumor targeted drugs can be used after mutation, such as exon 19 deletion, exon 21 L858R mutation; the other is drug-resistant mutation , that is, resistance to certain anti-tumor targeted drugs after mutation, such as T790M mutation, C797S mutation.
  • drug-sensitive mutation that is, anti-tumor targeted drugs can be used after mutation, such as exon 19 deletion, exon 21 L858R mutation
  • drug-resistant mutation that is, resistance to certain anti-tumor targeted drugs after mutation, such as T790M mutation, C797S mutation.
  • the first-generation EGFR small-molecule inhibitor drugs Gefitinib, Erlotinib, and Icotinib achieved significant clinical efficacy and prolonged survival in patients with EGFR-sensitizing mutations Expect. However, most of the patients who benefited from the drug developed resistance after a few months of use.
  • EGFRWT wild-type EGFR
  • Osimertinib the third-generation irreversible inhibitor that overcomes EGFR T790M resistance, can effectively treat advanced non-small cell lung cancer patients with epidermal growth factor receptor T790M mutation or resistance to other EGFR inhibitors.
  • Anaplastic lymphoma kinase also known as ALK tyrosine kinase receptor or CD246, is an active enzyme encoded by the ALK gene in humans.
  • the fusion genes involved in the formation of ALK are closely related to the occurrence and development of various tumors such as non-small cell lung cancer.
  • fusion oncogenes such as EML4-ALK (echinoderm microtubule-associated protein-like 4 and anaplastic lymphoma kinase fusion gene) account for about 3-7%. Therefore, the development of ALK fusion gene-positive protein kinase inhibitors has important clinical value.
  • One or more embodiments of the present application provide an arylphosphonium compound or a pharmaceutically acceptable salt thereof as a kinase inhibitor represented by the following formula (I), which can effectively inhibit various types of EGFR Activity of drug-resistant mutants (eg, EGFR del19, EGFR del19/T790M , EGFR del19/C797S , EGFR T790M/L858R , EGFR L858R/C797S , EGFR del19/T790M/C797S , EGFR L858R/T790M/C797S ) and fusion to ALK Genes and mutants (such as L1196M) also have significant inhibitory effects and can be used for the treatment, combination therapy, or prevention of various cancers.

蛋白激酶代表一大家族蛋白质,其在多种细胞过程的调控中以及细胞功能的维持控制中起着重要作用。它们包括增殖,凋亡,细胞骨架重排,分化,发育,免疫反应,神经系统功能和传导。另外,许多疾病和(或)机能紊乱与一种或多种激酶的活性失常,异常或失调相关。
肺癌是最常见的恶性肿瘤之一,一般分为小细胞肺癌(Small Cell Lung Cancer,SCLC)和非小细胞肺癌(Non-Small Cell Lung Cancer,NSCLC)两大类,但无论从地域区分中国还是全球,肺癌都是排在第一位。其中非小细胞肺癌(NSCLC)约占肺癌总数的80%以上,严重威胁着人类健康(中国肺癌杂志[J],2012 Feb 20;15(2):106–111)。
EGFR(epidermal growth factor receptor,EGFR)全名为表皮生长因子受体,是一种广泛分布于人体各种组织细胞膜上的具有酪氨酸激酶活性的跨膜糖蛋白。EGFR的突变和异常激活与多种肿瘤如非小细胞肺癌、乳腺癌、食管癌等肿瘤的发生发展、恶性程度、转移等密切相关。大部分的非小细胞肺癌(Non-small-celllung cancer,NSCLC)患者存在EGFR过量表达,在亚洲非小细胞肺癌人群中(尤其是中国人群),大概有40~50%属于EGFR突变,因此对EGFR的抑制能显著提高NSCLC患者的生存期。EGFR的常见突变可以分为两大类,一类是药物敏感突变,即突变后可以使用抗肿瘤靶向药物,例如19外显子缺失、21外显子L858R突变;另一类是耐药突变,即突变后对某种抗肿瘤靶向药物耐药,例如T790M突变、C797S突变。第一代EGFR小分子抑制剂药物吉非替尼(Gefitinib)、厄洛替尼(Erlotinib)和埃克替尼(Icotinib)在携带EGFR敏感突变的患者中获得了显著的临床疗效,延长了生存期。但获益患者在使用药物几个月后,大部分患者会产生耐药。其中,超过50%的耐药患者是由于EGFR发生了T790M突变产生耐药。第二代EGFR不可逆抑制剂药物阿法替尼(Afatinib)和来那替尼(Neratinib)虽然在临床前研究获得较好的结果,但对野生型EGFR(EGFRWT)缺乏选择性,具有较大皮肤毒性等副作用。第三代克服EGFR T790M耐药的不可逆抑制剂Osimertinib(AZD9291),在临床上能够有效治疗表皮生长因子受体T790M突变或对其它EGFR抑制剂耐药的晚期非小细胞肺癌患者。尽管Osimertinib在临床上治疗EGFRT790M突变的非小细胞肺癌取得了较大的成功,但是部分受益患者在经过9~14个月治疗后又出现了耐药的现象(Nature Medicine 2015,21(6),560-562)。经研究发现,高达40%的耐药患者由于(EGFR)C797S点突变导致了Osimertinib耐药。进一步的机制研究表明,(EGFR)C797S的点突变使797位的半胱氨酸转变为丝氨酸,导致Osimertinib无法与靶蛋白形成共价结合,最终引起耐药。目前临床上尚没有一款药物可针对新突变(C797S)有效的EGFR抑制剂。因此,迫切需要新类型,高选择性的EGFR抑制剂来解决(EGFR)C797S点突变导致的药物耐药性等问题。
间变性淋巴瘤激酶(Anaplastic lymphoma kinase,ALK),又称为ALK酪氨酸激酶受体或CD246,它是人体中由ALK基因编码的活性酶。ALK参与形成的融合基因与非小细胞肺癌等多种肿瘤的发生发展密切相关。在非小细胞肺癌患者 中,EML4-ALK(棘皮动物微管相关类蛋白4与间变性淋巴瘤激酶融合基因)等融合型癌基因约占3-7%。因此,开发针对ALK融合基因阳性的蛋白激酶抑制剂具有重要的临床价值另一方面,近年来随着非小细胞肺癌病人的增加和二代测序技术(深度测序)的应用普及,不断有研究者们发现,在有些非小细胞肺癌患者中能同时出现EGFR突变体和ALK基因融合的现象。因此,迫切需要新类型、高选择性的蛋白激酶抑制剂来解决(EGFR)C797S点突变导致的药物耐药性等问题,同时又能解决ALK基因融合和突变。
发明内容

每天观测小鼠的精神、活动、进食等一般情况,每周测3次体重;每周3次用游标卡尺测量各小鼠肿瘤的短径(a)及长径(b),按(a 2×b)/2公式计算肿瘤体积。根据测量计算的肿瘤体积计算出相对肿瘤体积(RTV),RTV=V t/V 0。其中V 0为随机分组(即d 0)时的肿瘤体积,V t为每一次测量(即d n)时的肿瘤体积。按下列公式计算抗肿瘤活性评价指标相对肿瘤增殖率:相对肿瘤增殖率T/C(%):

给药后每天两次观察。首次给药当天定义为试验第1天,连续观察14天,第15天实验结束。
实验剂量及分组及给药后第15天动物死亡情况见表12:
