Definitions

  • the invention relates to a class of pyrimidine compounds, their preparation method and application.
  • Tumor is one of the most important problems that endanger human health, and lung cancer is one of the malignant tumors that threaten people's health and life the most.
  • Lung cancer is mainly divided into small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC), of which about 80% are NSCLC.
  • SCLC small cell lung cancer
  • NSCLC non-small cell lung cancer
  • the most common mutation in non-small cell lung cancer and targeted drugs is "epidermal growth factor receptor" (EGFR) mutation. Therefore, the use of epidermal growth factor receptor EGFR inhibitors-EGFR-TKI targeted drugs is one of the biggest research hotspots in the treatment of lung cancer.
  • EGFR epidermal growth factor receptor
  • Epidermal growth factor receptor belongs to the protein tyrosine kinase (PTK) family, consisting of EGFR (Erb-B1), ErbB2 (HER-2/neu), Erb-B3 and Erb-B4, and is recognized as the Critical driver in cell growth and proliferation.
  • PTK protein tyrosine kinase
  • Overexpression and mutation of EGFR have been clearly confirmed to lead to uncontrolled cell growth, which is related to the disease process of most cancers, such as lung cancer, colon cancer, breast cancer and so on.
  • the first generation is reversible targeted drugs, such as gefitinib, erlotinib, and icotinib.
  • the second generation is irreversible targeted drugs, such as afatinib and dacomitinib.
  • the first and second generation targeted drugs are effective, most patients will develop drug resistance after 1-2 years of drug use.
  • 50% of drug resistance is related to T790M mutation.
  • the third-generation EGFR-targeted drug osimertinib can bind to the EGFR T790M mutation site and inhibit the tumor drug resistance caused by the T790M mutation.
  • the C797S mutation is manifested by the mutation of the cysteine residue to serine, which destroys the binding of the EGFR protein to the third-generation targeted drugs, thus preventing the unilateral phosphorylation of EGFR and the activation of downstream signaling pathways.
  • the technical problem to be solved by the present invention is to overcome the defects of existing EGFR inhibitors with single structure and poor inhibitory effect on C797S mutation, and provide a class of pyrimidine compounds, their intermediates, preparation methods and applications.
  • the compound of the present invention has a novel structure, has good inhibitory effect on EGFR Del19/T790M/C797S mutation, and is expected to treat and/or prevent various diseases mediated by EGFR.

Description

一类嘧啶类化合物、其制备方法及应用
本申请要求申请日为2021年12月1日的中国专利申请2021114525077的优先权。本申请引用上述中国专利申请的全文。
技术领域
本发明涉及一类嘧啶类化合物、其制备方法及应用。
背景技术
肿瘤是危害人类健康的最重要问题之一,而肺癌是对人们健康和生命威胁最大的恶性肿瘤之一。肺癌主要分为小细胞肺癌(SCLC)和非小细胞肺癌(NSCLC),其中约80%为NSCLC。而非小细胞肺癌中最常见,且有针对性靶向药物的突变就是“表皮生长因子受体”(EGFR)突变。因此,表皮生长因子受体EGFR抑制剂-EGFR-TKI靶向药的使用,是肺癌治疗的一个最大研究热点。
表皮生长因子受体(EGFR)属于蛋白酪氨酸激酶(PTK)家族,由EGFR(Erb-B1)、ErbB2(HER-2/neu)、Erb-B3和Erb-B4组成,被确认为是在细胞生长和增殖过程中至关重要的驱动因素。EGFR的过度表达和突变已被明确证实将导致不可控的细胞生长,与大部分癌症疾病进程有关,如肺癌、结肠癌、乳腺癌等。
目前,上市的EGFR抑制剂有一、二、三代。第一代为可逆的靶向药物,例如吉非替尼、厄洛替尼、埃克替尼。第二代为不可逆的靶向药物,例如阿法替尼以及达克替尼。第一、二代靶向药物虽然疗效显著,但多数患者都会在使用药物1-2年出现耐药性。EGFR抑制剂耐药的患者中,有50%的耐药与T790M突变有关。第三代EGFR靶向药物奥希替尼能与EGFR T790M突变位点结合,抑制由T790M突变引起的肿瘤耐药,它的问世给更多的肺癌患者带来了好的生存获益。然而第三代靶向药也不可避免的产生耐药,其耐药原因为C797S突变。C797S突变体现为半胱氨酸残基突变成丝氨酸,这一突变破坏了EGFR蛋白与第三代靶向药物结合,从而无法阻止EGFR单边的磷酸化以及下游信号通路的活化。目前对于奥希替尼耐药后容易出现的两种三重突变:del19/T790M/C797S和L858R/T790M/C797S的应对尚无成熟的治疗手段。
所以,针对C797S突变,克服奥西替尼耐药,为患者提供更加安全有效的EGFR抑制剂具有非常重要的研究意义。
发明内容
本发明所要解决的技术问题是克服现有的EGFR抑制剂结构单一、对C797S突变抑制效果差的缺陷,而提供了一类嘧啶类化合物、其中间体、制备方法及其应用。本发明的化合物结构新颖,对EGFR Del19/T790M/C797S突变具有良好的抑制作用,有望治疗和/或预防由EGFR介导的多种疾病。

除非另外说明,应当应用本文所使用的下列定义。出于本发明的目的,化学元素与元素周期表CAS版,和《化学和物理手册》,第75版,1994一致。此外,有机化学一般原理可参考″Organic Chemistry″,Thomas Sorrell,University Science Books,Sausalito:1999,和″March′s Advanced Organic Chemistry”by Michael B.Smith and Jerry March,John Wiley&Sons,New York:2007中的描述,其全部内容通过引用并入本文。
在本说明书中,可由本领域技术人员选择基团及其取代基以提供稳定的结构部分和化合物。当通过从左向右书写的常规化学式描述取代基时,该取代基也同样包括从右向左书写结构式时所得到的在化学上等同的取代基。
在本文中定义的某些化学基团前面通过简化符号来表示该基团中存在的碳原子总数。例如,C 1~C 4烷基或C 1-4烷基是指具有总共1、2、3或4个碳原子的如下文所定义的烷基。简化符号中的碳原子总数不包括可能存在于所述基团的取代基中的碳。
在本文中,取代基中定义的数值范围如0至4、1-4、1至3等表明该范围内的整数,如1-6为1、2、3、4、5、6。
术语“包括”为开放式表达,即包括本发明所指明的内容,但并不排除其他方面的内容。
术语“被取代的”是指特定原子上的任意一个或多个氢原子被取代基取代,只要特定原子的价态是正常的并且取代后的化合物是稳定的。
一般而言,术语“取代的”表示所给结构中的一个或多个氢原子被具体取代基所取代。进一步地,当该基团被1个以上所述取代基取代时,所述取代基之间是相互独立,即,所述1个以上的取代基可以是互不相同的,也可以是相同的。除非其他方面表明,一个取代基团可以在被取代基团的各个可取代的位置进行取代。当所给出的结构式中不只一个位置能被选自具体基团的一个或多个取代基所取代,那么取代基可以相同或不同地在各个位置取代。
在本说明书的各部分,本发明公开化合物的取代基按照基团种类或范围公开。特别指出,本发明包括这些基团种类和范围的各个成员的每一个独立的次级组合。术语“C x~C y烷基″或“C x-y烷基″是指含 有x至y个碳原子的直链或支链饱和烃。例如,术语“C 1~C 6烷基”或“C 1-6烷基”特别指独立公开的甲基、乙基、C 3烷基、C 4烷基、C 5烷基和C 6烷基;“C 1~C 4烷基”特指独立公开的甲基、乙基、C 3烷基(即丙基,包括正丙基和异丙基)、C 4烷基(即丁基,包括正丁基、异丁基、仲丁基和叔丁基)。
本文所用术语“部分”、“结构部分”、“化学部分”、“基团”、“化学基团”是指分子中的特定片段或官能团。化学部分通常被认为是嵌入或附加到分子上的化学实体。
当所列举的取代基中没有指明其通过哪一个原子连接到化学结构通式(包括但未具体提及的化合物)中时,这种取代基可以通过其任何原子相键合。取代基和/或其变体的组合只有在这样的组合会产生稳定的化合物的情况下才是被允许的。
当所列举的基团中没有明确指明其具有取代基时,这种基团仅指未被取代。例如当“C 1~C 4烷基”前没有“取代或未取代的”的限定时,仅指“C 1~C 4烷基”本身或“未取代的C 1~C 4烷基”。
在本发明的各部分,描述了连接取代基。当该结构清楚地需要连接基团时,针对该基团所列举的马库什变量应理解为连接基团。例如,如果该结构需要连接基团并且针对该变量的马库什基团定义列举了“烷基”,则应该理解,该“烷基”代表连接的亚烷基基团。
在一些具体的结构中,当烷基基团清楚地表示为连接基团时,则该烷基基团代表连接的亚烷基基团,例如,基团“卤代-C 1-4烷基”中的C 1-4烷基应当理解为C 1-4亚烷基。
术语“卤素”是指氟、氯、溴或碘,尤其指F或Cl。
在本申请中,作为基团或是其它基团的一部分(例如用在卤代烷基、氘代烷基等基团中),术语“烷基”是指包括具有指定碳原子数目的支链和直链的饱和脂族烃基,仅由碳原子和氢原子组成、具有例如1至12个(优选1至8个,更优选1至6个,更优选1至4个)碳原子,且通过单键与分子的其余部分连接,其中,丙基为C 3烷基(包括同分异构体,例如正丙基或异丙基);丁基为C 4烷基(包括同分异构体,例如正丁基、仲丁基、异丁基或叔丁基);戊基为C 5烷基(包括同分异构体,例如正戊基、1-甲基-丁基、1-乙基-丙基、2-甲基-1-丁基、3-甲基-1-丁基、异戊基、叔戊基或新戊基);己基为C 6烷基(包括同分异构体,例如正己基、1-乙基-2-甲基丙基、1,1,2-三甲基丙基、1,1-二甲基丁基、1,2-二甲基丁基、2,2-二甲基丁基、1,3-二甲基丁基、2-乙基丁基、2-甲基戊基、3-甲基戊基、4-甲基戊基、2,3-二甲基丁基)。例如包括但不限于甲基、乙基、正丙基、异丙基、正丁基、异丁基、仲丁基、叔丁基、正戊基、2-甲基丁基、2,2-二甲基丙基、正己基、正庚基、2-甲基己基、3-甲基己基、正辛基、壬基和癸基等其类似烷基。

除非另有说明,本发明采用质谱、元素分析的传统方法,各步骤和条件可参照本领域常规的操作步骤和条件。
除非另有指明,本发明采用分析化学、有机合成化学和光学的标准命名及标准实验室步骤和技术。在某些情况下,标准技术被用于化学合成、化学分析、发光器件性能检测。
另外,需要说明的是,除非以其他方式明确指出,在本发明中所采用的描述方式“...独立地为”应做广义理解,是指所描述的各个个体之间是相互独立的,可以独立地为相同或不同的具体基团。更详细地,描述方式“...独立地为”既可以是指在不同基团中,相同符号之间所表达的具体选项之间互相不影响;也可以表示在相同的基团中,相同符号之间所表达的具体选项之间互相不影响。
除非另有规定,本文使用的所有技术术语和科学术语具有要求保护主题所属领域的标准含义。倘若对于某术语存在多个定义,则以本文定义为准。
在不违背本领域常识的基础上,上述各优选条件,可任意组合,即得本发明各较佳实例。
本发明所用试剂和原料均市售可得。
本发明的积极进步效果在于:该嘧啶类化合物对EGFRDel19/T790M/C797S突变具有良好的抑制作用,有望治疗和/或预防由EGFR介导的多种疾病,例如对第一、二、三代EGFR抑制剂耐药的疾病,又例如由EGFR Del19/T790M/C797S突变介导的疾病。

测试实施例1:对PC-9-EGFR-Del19-T790M-C797S细胞的增殖抑制作用
通过磺酰罗丹明B法(SRB法)测定化合物在体外对人非小细胞肺癌PC-9外源稳定过表达EGFR蛋白存在Del19/T790M/C797S三突变的PC-9-EGFR-Del19-T790M-C797S细胞的增殖抑制活性。
细胞来源:PC-9-EGFR-Del19-T790M-C797S细胞购自南京科佰生物科技有限公司。
PC-9-EGFR-Del19-T790M-C797S细胞培养于含嘌呤霉素(2μg/ml)的含10%胎牛血清的RPMI1640完全培养基中。取处于对数生长期的PC-9-EGFR-Del19-T790M-C797S细胞,按5000细胞/135μL完全培养基/孔的细胞密度,接种在96孔板中,置于37℃含有5%CO 2的恒温培养箱中培养24小时确保细胞完全贴壁。将各化合物事先溶解在二甲基亚砜(DMSO)中配制成10mM的储存液,再依次用DMSO、完全培养基稀释化合物。取出接种细胞的96孔板,取其中一块单独作为无生长对照组(0小时细胞无生长的培养基对照组);其他96孔板则每孔加入15μL的不同浓度化合物,使其终浓度为2500、625、156.25、39.06、9.77、2.44、0.61、0.15、0.04、0.01nM,每个化合物浓度设置三个复孔,并设阴性对照组(含细胞、未加化合物的培养基对照组),每个孔中DMSO的浓度均为0.5%。
留出的无生长对照组即刻终止培养,其他的96孔板继续于37℃含有5%CO 2的恒温培养箱中培养72小时再终止培养。终止培养方法如下:每孔加入50μL预冷(4℃)的50%三氯乙酸水溶液,4℃放置固定1小时,用纯化水洗涤至少5次,空气中自然干燥或60℃烘箱干燥。
用含1%冰乙酸的纯化水配制4mg/mL的SRB溶液,每孔加入100μL,室温染色1小时,弃上清,用1%冰乙酸洗涤至少5次除去非特异结合,干燥待用。每孔加入150μL的10mM的三羟甲基氨基甲烷盐酸盐溶液(Tris-HCl溶液)溶解,在510nm波长处测光密度值(OD值),并进行数据整理计算细胞增殖抑制率。
细胞增殖抑制率=[(OD 72小时阴性对照组-OD 72小时给药化合物组)/(OD 72小时阴性对照组-OD 无生长对照组)]×100%。
使用GraphPad Prism 8.3软件分析数据,利用非线性S曲线回归来拟合数据得出剂量-效应曲线,并由此计算IC 50值,结果见表1。
