Definitions

  • the present invention relates to the field of medicinal chemistry and pharmacotherapeutics, and in particular to aldehyde-based compounds as enterovirus proteases or coronavirus main protease inhibitors, processes for their preparation, pharmaceutical compositions containing such compounds, and uses.
  • Infectious diseases caused by enteroviruses are common in children. Its clinical features are mild patient burnout, fatigue, low fever, etc. Severe patients can be infected with the whole body, and the vital organs such as brain, heart, liver and spinal cord are damaged, and the sequelae are worse and severe. These diseases are spread all over the world and have a high incidence in humid, warm, poorly populated areas and densely populated areas. Some viruses are often prevalent, and the prevalence in different years can be caused by different types of viruses, and some viruses have a periodicity.
  • EV71 and CVA16 are highly homologous in evolution. Both viruses belong to the family Picaraviridae, Enterovirus, and Human enterovirus A in their taxonomic status. Generally, the clinical symptoms caused by CVA16 infection are milder and less associated with neurological diseases. In addition to causing hand, foot and mouth disease, EV71 often causes serious central nervous system diseases such as encephalitis, meningitis, aseptic meningitis, and acute Delayed paralysis, etc., more serious can lead to pulmonary edema and heart failure, and the mortality rate is extremely high.
  • Enterovirus is a naked virion with a icosahedral structure. Because it is coated with a lipid-free outer membrane, conventional disinfectants are not effective in inactivating the virus. Although the two pathogens are sensitive to temperature, they are completely inactivated at 56 ° C for 30 min, but the virus can survive for several weeks at 4 ° C, and can survive for several years at -20 ° C, and can survive for a long time in the natural environment. Therefore, it is difficult to effectively prevent and control enterovirus infection.
  • the enterovirus is a single strand of sense strand RNA, which has 5'- and 3'-untranslated regions at both ends, and a viral protein coding region in the middle.
  • the coding region contains only one open reading frame, so the original translation product of the virus is a polyprotein precursor with a molecular weight of about 243 kDa.
  • the polyprotein needs to be further cleaved by the virus's own encoded 2A and 3C proteases and processed into 11 mature functional protein subunits (Vp1-Vp4, 2A-2C, 3A-3D) to complete viral replication and assembly.
  • the 2A protease is responsible for the cleavage of the Vp1/2A junction sequence; the 3C protease is responsible for the cleavage of the other 8 sites in the polyprotein (including Vp2/Vp3, Vp3/Vp1, 2A/2B, 2B/2C, 2C/3A, 3A).
  • /3B, 3B/3C, 3C/3D junction sequence because it can recognize multiple different sites, plays a major role in the processing of viral polyprotein precursors, so 3C protease is also called primary protease.
  • the 3C protease also has RNA binding activity. Shin-Ru13 et al.
  • EV71 3C can directly participate in viral replication by binding to the 5'-UTR of the viral genome through two functional motifs, "KFRDI” and "VGK".
  • 3C protease promotes virus proliferation by interacting with various host factors.
  • the host's own protein translation system is shut down by cleavage of the CstF-64 host factor, providing more raw material for viral protein synthesis.
  • the production of the host antiviral factor interferon beta (IFN-[beta]) is inhibited by binding to retinoic acid-inducible gene I (RIG-I).
  • 3C protease inhibitors have the potential to be used in clinical and treatment of diseases associated with enterovirus infections such as hand, foot and mouth disease.

Description

醛基类化合物及其制法和用途Aldehyde-based compound and preparation method and use thereof 技术领域Technical field
本发明涉及药物化学和药物治疗学领域，具体涉及作为肠道病毒蛋白酶或冠状病毒主蛋白酶抑制剂的醛基类化合物、其制备方法、含此类化合物的药物组合物及用途。The present invention relates to the field of medicinal chemistry and pharmacotherapeutics, and in particular to aldehyde-based compounds as enterovirus proteases or coronavirus main protease inhibitors, processes for their preparation, pharmaceutical compositions containing such compounds, and uses.
背景技术Background technique
肠道病毒属病毒引起的传染病多发于儿童。其临床特征为轻度患者倦怠、乏力、低热等，重症患者可全身感染，脑、心、肝、脊髓等重要器官损伤，愈后较差，并有后遗症，严重者会导致死亡。此类疾病分布于全球各地，在潮湿温暖﹑卫生条件差﹑人口密集地区发病率高。有些病毒的感染常发生流行，不同年份的流行可由不同种型的病毒引起，有些病毒感染的流行有周期性。Infectious diseases caused by enteroviruses are common in children. Its clinical features are mild patient burnout, fatigue, low fever, etc. Severe patients can be infected with the whole body, and the vital organs such as brain, heart, liver and spinal cord are damaged, and the sequelae are worse and severe. These diseases are spread all over the world and have a high incidence in humid, warm, poorly populated areas and densely populated areas. Some viruses are often prevalent, and the prevalence in different years can be caused by different types of viruses, and some viruses have a periodicity.
其中近些年在亚太地区大规模爆发的手足口病便是由多种的肠病毒引致，其中以柯萨奇病毒A组16型(CVA16)和肠道病毒71型(EV71)最为常见。目前尚无针对手足口病的预防及治疗方法，临床上仅仅采用广谱抗病毒药物进行治疗。所以现在开发一种用于手足口病治疗的EV71和CVA16抑制剂是一件非常有意义且富有挑战性的工作。Among them, the large-scale outbreak of hand, foot and mouth disease in the Asia-Pacific region in recent years has been caused by a variety of enteroviruses, among which Coxsackievirus A group 16 (CVA16) and enterovirus 71 (EV71) are the most common. At present, there is no prevention and treatment method for hand, foot and mouth disease, and only broad-spectrum antiviral drugs are used for clinical treatment. So developing an EV71 and CVA16 inhibitor for the treatment of hand, foot and mouth disease is a very interesting and challenging task.
EV71和CVA16在进化上高度同源，两种病毒在分类地位上均属于微小RNA病毒科(Picronaviridae)，肠病毒属(Enterovirus)，人类肠病毒A种(Human enterovirus A)。通常CVA16感染引起的临床症状较温和，较少伴发神经系统病变；而EV71除引起手足口病外，还常常引起严重的中枢神经系统疾病，如脑炎、脑膜炎、无菌性脑膜炎、急性迟缓性麻痹等，更严重的可导致肺水肿和心脏衰竭，死亡率极高。EV71 and CVA16 are highly homologous in evolution. Both viruses belong to the family Picaraviridae, Enterovirus, and Human enterovirus A in their taxonomic status. Generally, the clinical symptoms caused by CVA16 infection are milder and less associated with neurological diseases. In addition to causing hand, foot and mouth disease, EV71 often causes serious central nervous system diseases such as encephalitis, meningitis, aseptic meningitis, and acute Delayed paralysis, etc., more serious can lead to pulmonary edema and heart failure, and the mortality rate is extremely high.
肠道病毒为正二十面体结构的裸露的病毒粒子，因其无脂质外膜包被，常规的消毒液均不能有效将病毒灭活。两种致病原虽对温度敏感，56℃下30min即彻底失活，但病毒在4℃下可存活数周，-20℃下可存活数年，在自然环境中可长期存活。因此，有效防控肠道病毒感染存在较大难度。Enterovirus is a naked virion with a icosahedral structure. Because it is coated with a lipid-free outer membrane, conventional disinfectants are not effective in inactivating the virus. Although the two pathogens are sensitive to temperature, they are completely inactivated at 56 ° C for 30 min, but the virus can survive for several weeks at 4 ° C, and can survive for several years at -20 ° C, and can survive for a long time in the natural environment. Therefore, it is difficult to effectively prevent and control enterovirus infection.
肠道病毒为单股正义链RNA，其两端分别为5’-和3’-非翻译区；中间为病毒蛋白编码区。该编码区只包含一个开放阅读框，故病毒的原初翻译产物为一个分子量约243KDa的多聚蛋白前体。该多聚蛋白需要进一步被病毒自身编码的2A和3C蛋白酶切割，加工成11个成熟的功能性蛋白亚基(Vp1-Vp4，2A-2C，3A-3D)以完成病毒的复制和装配。其中2A蛋白酶负责Vp1/2A接合序列的切割；而3C蛋白酶负责多聚蛋白中另外8个位点的切割(包括Vp2/Vp3，Vp3/Vp1，2A/2B，2B/2C，2C/3A，3A/3B，3B/3C，3C/3D接合序列)，因其可以识别多个不同的位点，在病毒多聚蛋白前体的加工中发挥主要作用，因此3C蛋白酶又被称为主蛋白酶。此外，3C蛋白酶还具有RNA结合活性。Shin-Ru13等证明EV71 3C可以通过“KFRDI”和“VGK”两个功能基序结合病毒基因组的5’-UTR，从而直接参与病毒的复制。另一方面，3C蛋白酶又通过与多种宿主因子相互作用而促进病毒的增殖。如通过切割CstF-64宿主因子而关闭宿主自身的蛋白质翻译系统，从而为病毒蛋白合成提供更多的原料。通过结合视黄酸诱导基因I(RIG-I)而抑制宿主抗病毒因子干扰素β(IFN-β)的产生。3C在肠道病毒病毒生活周期中的关键作用，使得该蛋白酶可以作为有效的抗病毒靶点；而在人类中缺少3C蛋白酶的同源蛋白，因此，有效的 3C蛋白酶抑制剂有应用于临床、治疗手足口病等肠道病毒感染引起的相关疾病的可能。The enterovirus is a single strand of sense strand RNA, which has 5'- and 3'-untranslated regions at both ends, and a viral protein coding region in the middle. The coding region contains only one open reading frame, so the original translation product of the virus is a polyprotein precursor with a molecular weight of about 243 kDa. The polyprotein needs to be further cleaved by the virus's own encoded 2A and 3C proteases and processed into 11 mature functional protein subunits (Vp1-Vp4, 2A-2C, 3A-3D) to complete viral replication and assembly. The 2A protease is responsible for the cleavage of the Vp1/2A junction sequence; the 3C protease is responsible for the cleavage of the other 8 sites in the polyprotein (including Vp2/Vp3, Vp3/Vp1, 2A/2B, 2B/2C, 2C/3A, 3A). /3B, 3B/3C, 3C/3D junction sequence), because it can recognize multiple different sites, plays a major role in the processing of viral polyprotein precursors, so 3C protease is also called primary protease. In addition, the 3C protease also has RNA binding activity. Shin-Ru13 et al. demonstrated that EV71 3C can directly participate in viral replication by binding to the 5'-UTR of the viral genome through two functional motifs, "KFRDI" and "VGK". On the other hand, 3C protease promotes virus proliferation by interacting with various host factors. The host's own protein translation system is shut down by cleavage of the CstF-64 host factor, providing more raw material for viral protein synthesis. The production of the host antiviral factor interferon beta (IFN-[beta]) is inhibited by binding to retinoic acid-inducible gene I (RIG-I). The key role of 3C in the life cycle of enteroviruses makes this protease an effective antiviral target; whereas in humans it lacks a homologous protein of the 3C protease, therefore, effective 3C protease inhibitors have the potential to be used in clinical and treatment of diseases associated with enterovirus infections such as hand, foot and mouth disease.
综上所述，本领域迫切需要开发3C蛋白酶抑制剂。In summary, there is an urgent need in the art to develop 3C protease inhibitors.
