  • Hepatitis B virus is an enveloped, partially double-stranded DNA (dsDNA), hepatovirus DNA family (Hepadnaviridae) virus. Its genome contains four overlapping reading frames: the pronuclear/nuclear gene, the polymerase gene, the UM and S genes (which encode three envelope proteins), and the X gene.
  • the partially double-stranded DNA genome is transformed into a covalently closed circular DNA (cccDNA) in the host cell nucleus (open loop DNA, rcDNA) and the viral mRNA is transcribed.
  • the pre-genomic RNA which is also encoded by the core protein and Pol, is used as a template for reverse transcription, which regenerates this portion of the dsDNA genome (rcDNA) in the nucleocapsid.

Description

双并环脲类核衣壳抑制剂及其药物用途Biparacyclic urea nucleocapsid inhibitor and its pharmaceutical use 技术领域Technical field
本发明属于医药领域,具体地,本发明涉及用于治疗乙型肝炎的芳基并环酰胺类化合物及其用途。The present invention belongs to the field of medicine, and in particular, the present invention relates to an aryl-cycloamide compound for use in the treatment of hepatitis B and uses thereof.
背景技术Background technique
乙型肝炎病毒(HBV)是一种有包膜的、部分双链DNA(dsDNA)的、嗜肝病毒DNA家族(肝病毒科(Hepadnaviridae))的病毒。它的基因组包含4个重叠阅读框:前核/核基因,聚合酶基因,UM和S基因(它们编码三个包膜蛋白质),以及X基因。在感染前时,该部分双链DNA基因组在宿主细胞核中(开环DNA,rcDNA)转变为共价闭合环状DNA(cccDNA)并且该病毒mRNA进行转录。一旦被壳体化,该前基因组RNA(pgRNA)(其还为核心蛋白和Pol编码)作为模板用于逆转录,这种逆转录在核衣壳中再生该部分dsDNA基因组(rcDNA)。Hepatitis B virus (HBV) is an enveloped, partially double-stranded DNA (dsDNA), hepatovirus DNA family (Hepadnaviridae) virus. Its genome contains four overlapping reading frames: the pronuclear/nuclear gene, the polymerase gene, the UM and S genes (which encode three envelope proteins), and the X gene. At the time of infection, the partially double-stranded DNA genome is transformed into a covalently closed circular DNA (cccDNA) in the host cell nucleus (open loop DNA, rcDNA) and the viral mRNA is transcribed. Once encapsidated, the pre-genomic RNA (pgRNA), which is also encoded by the core protein and Pol, is used as a template for reverse transcription, which regenerates this portion of the dsDNA genome (rcDNA) in the nucleocapsid.
HBV在亚洲和非洲的部分地区造成了流行病,并且它在中国是地方性的。HBV已经在全球感染了大约20亿人,其中大约3.5亿人发展成了慢性传染病。该病毒造成了乙型肝炎疾病并且慢性传染病与肝硬化和肝癌的发展的高增加风险相关联。HBV has caused epidemics in parts of Asia and Africa, and it is endemic in China. HBV has infected about 2 billion people worldwide, and about 350 million of them have developed chronic infectious diseases. The virus causes hepatitis B disease and chronic infectious diseases are associated with a high increased risk of development of cirrhosis and liver cancer.
乙型肝炎病毒的传播来源于暴露于传染性的血液或体液,同时在血清中具有高效价DNA的慢性携带者的唾液、泪液以及尿液中检测到了病毒DNA。The spread of hepatitis B virus is derived from exposure to infectious blood or body fluids, while viral DNA is detected in the saliva, tears, and urine of chronic carriers with high-priced DNA in serum.
虽然目前存在一种有效的并且具有良好耐受性的疫苗,但是直接治疗的选择目前还限于干扰素以及以下的抗病毒药;替诺福韦、拉米夫定、阿德福韦、恩替卡韦以及替比夫定。Although there is currently an effective and well tolerated vaccine, the choice of direct treatment is currently limited to interferon and the following antiviral drugs; tenofovir, lamivudine, adefovir, entecavir and Telbivudine.
此外,杂芳基二氢嘧啶(HAPs)在组织培养以及动物模型中被鉴别作为一类HBV抑制剂。WO 2013/006394(公开于2013年1月10日)和WO 2013/096744(公开于2013年6月27日)还公开了涉及抗HBV活性的氨磺酰基-芳基酰胺。In addition, heteroaryldihydropyrimidines (HAPs) have been identified as a class of HBV inhibitors in tissue culture as well as in animal models. A sulfamoyl-arylamide involving anti-HBV activity is also disclosed in WO 2013/006394 (published on Jan. 10, 2013) and WO 2013/096744 (published on June 27, 2013).
然而,在这些直接的HBV抗病毒药中会遇到的是毒性、致突变性、缺乏选择性、疗效差、生物利用度差以及合成困难等问题。However, problems encountered in these direct HBV antivirals are toxicity, mutagenicity, lack of selectivity, poor efficacy, poor bioavailability, and difficulty in synthesis.
因此,本领域需要开发具有如效价高、毒性更低等优点的HBV抑制剂。Therefore, there is a need in the art to develop HBV inhibitors having advantages such as high potency and lower toxicity.
发明内容Summary of the invention
本发明的目的是提供一类效价高、毒性更低的HBV抑制剂。It is an object of the present invention to provide a class of HBV inhibitors which are relatively potent and less toxic.
本发明的第一方面,提供了一种化学式A所示的化合物、或其立体异构体或互变异构体、或其药学上可接受的盐、水合物或溶剂化物,According to a first aspect of the invention, there is provided a compound of the formula A, or a stereoisomer or tautomer thereof, or a pharmaceutically acceptable salt, hydrate or solvate thereof,
