Description
본 발명은 퀴나졸린 유도체, 이의 제조방법 및 이를 함유하는 인플루엔자 바이러스 치료용 약학적 조성물에 관한 것이다.The present invention relates to a quinazoline derivative, a process for producing the same, and a pharmaceutical composition for treating influenza virus containing the same.
독감(인플루엔자)은 오소믹소바이러스과의 인플루엔자 바이러스(바이러스)가 유발하는 감염성 질환이다. 인플루엔자 바이러스는 계절마다 수천에서 수만 명이 사망하는 유행성 인플루엔자를 전 세계에 걸쳐 일으킨다. 20세기에는 새로운 바이러스로 일어난 인플루엔자의 세계적 유행이 세 번 있었으며 수천만 명에 이르는 사람들이 사망했다. 이런 변종 바이러스는 다른 동물에게서 인간으로 감염이 일어날 때, 인간을 숙주로 삼는 종이 다른 동물을 숙주로 삼는 종에게서 유전자를 받았을 때 자주 생긴다. 1990년 아시아에서 출현한 H5N1의 등장은 세계적 인플루엔자 유행에 큰 관심을 불러 일으켰으나, 이때의 종은 인간 대 인간 감염에 특화되도록 변이하지는 않았다. 2009년 4월에는 멕시코에서 H1N1의 변종이 출현 여러 국가로 번졌다. 국제보건기구(WHO)는 2009년 7월 11일 이 유행을 '세계적 유행'으로 규정했다. Influenza (influenza) is an infectious disease caused by the influenza virus (virus) of Osomixovirus. Influenza viruses cause pandemic influenza throughout the world, where thousands to tens of thousands of people die each season. In the 20th century, there was a global epidemic of influenza caused by a new virus, and tens of millions of people were killed. This variant virus occurs frequently when an infection occurs from another animal to a human, when the host, the host, receives the gene from a host that uses another host as the host. The emergence of H5N1, which appeared in Asia in 1990, attracted great interest in the global influenza epidemic, but the species at this time were not mutated to be specific to human-to-human infections. In April 2009, variants of H1N1 emerged in Mexico and emerged in several countries. The International Health Organization (WHO) on July 11, 2009 defined the epidemic as a "global epidemic."
인플루엔자 바이러스는 항원형에 따라 A, B, C형 세 가지로 나뉜다. 바이러스 A형은 여러 동물이 숙주가 될 수 있는 반면, 바이러스 B형과 C형은 사람이 주로 숙주가 된다. 인플루엔자 유행은 대부분 A, B형에 의해 발생하며, 바이러스 C형 감염은 흔하지 않고 대개 가벼운 경과를 밟는다. 바이러스 입자 표면에는 항원성을 지닌 돌기들이 있다. A형과 B형의 돌기에는 특이한 혈구응집소(hemagglutinin, HA)와 뉴라미니다제(neuraminidase, NA)가 포함되어 있으며, C형에는 뉴라미니다제가 없다. 혈구응집소는 숙주 동물의 세포에 부착하는데 관여한다. 뉴라미니다제는 기도 뮤신(mucin) 내의 뉴라민산(neuraminic acid) 제거(뮤신은 혈구응집소에 대한 억제 효과가 있어서 바이러스가 세포에 부착되는 것을 방해), 숙주로부터 바이러스의 유리 및 바이러스간 응집 방지 작용을 하는 것으로 알려져 있다. A형은 혈구응집소와 뉴라미니다제의 항원형에 따라 다시 아형으로 분류된다. 사람의 감염을 일으키는 A형 인플루엔자 바이러스의 혈구응집소에는 H1, H2, H3 등 16 가지가 있고, 뉴라미니다제에는 N1, N2 등 9 가지가 있으며 이들의 조합에 의해 H3N2, H1N1, H2N2 등으로 분류된다. 인플루엔자 바이러스 이름은 형/분리장소/분리번호/분리연도(아형)의 순으로 표기하고 있다. 예를 들면, A/Hong Kong/8/68(H3N2)와 같이 표기한다.Influenza viruses are divided into three types, A, B, and C, depending on the type of antigen. Virus A can be a host of several animals, while virus B and C are predominantly human hosts. Most influenza epidemics are caused by types A and B, and infection with the virus type C is uncommon and usually follows a light course. On the virus particle surface, there are protuberances with antigenicity. The A and B protrusions contain a unique hemagglutinin (HA) and neuraminidase (NA), and no C-type neuraminidase. Hemagglutinin aggregates are involved in adhering to host cells. Neuraminidase inhibits the neuraminic acid in the airway mucin (mucin inhibits the attachment of the virus to the cells due to its inhibitory effect on the hemagglutinin) It is known to work. Type A is again subclassified according to the hematopoietic aggregation and the anti-circularity of neuraminidase. There are 16 types of hemagglutinin of influenza A virus causing human infection. H1, H2, and H3 have 16 kinds. Agglutination of N1 and N2 is included in neuraminidase. H3N2, H1N1, H2N2 etc. do. The name of the influenza virus is written in the order of type / separation site / separation number / separation year (subtype). For example, A / Hong Kong / 8/68 (H3N2).
인플루엔자 바이러스들 항원에 대한 특이 항체 유무가 면역력을 결정한다. 인플루엔자 바이러스에는 2가지의 항원형의 변이가 있는데, H1에서 H2로 변하는 것과 같이 유전자 재배열에 의해 HA 또는 NA에 큰 변화가 일어나는 것을 항원의 대변이(shift), 같은 아형 안에서 점 돌연변이의 축적으로 항원성이 약간 변하는 것을 항원의 소변이(drift)라고 한다. 인플루엔자 바이러스 A의 대유행은 항원의 대변이에 의해 10~40년을 주기로 일어나며 그 중간에는 소변이로 인해 2~3년을 주기로 소유행이 있다. B형의 큰 유행은 대개 4~7년을 주기로 일어난다. A형의 대유행시에서는 5~14세 소아의 감염률이 50%로 가장 높고 소유행시에는 같은 연령의 감염률이 약 15%인 것으로 알려져 있다. 우리나라에서는 최근 4회의 호흡기 바이러스 유행기간동안 관찰한 바에 의하면 인플루엔자 A는 매년, 인플루엔자 B는 2년마다 유행하였다.The presence or absence of specific antibodies to the influenza virus antigens determines immunity. There are two antiviral variants in influenza virus: the shift of antigen in HA or NA due to gene rearrangement such as the change from H1 to H2, the accumulation of point mutations in the same subtype, A slight change in sex is called the antigen's urine (drift). The pandemic influenza A virus is caused by the feces of the antigen every 10 to 40 years, and in the middle of the pandemic, it is carried out every 2 to 3 years. The great outbreak of type B usually occurs every four to seven years. In the pandemic of type A, the infection rates of children between 5 and 14 years old are the highest at 50%, and infection rates of the same age are known to be about 15% at the time of ownership. In Korea, influenza A was observed every year, and influenza B was observed every two years according to the recent 4 respiratory viral epidemics.
두 계열의 항바이러스 약물이 인플루엔자 치료에 사용된다. 뉴라미니다제 저해제와 M2 단백질 저해제 (아다만테인 유도체)가 항바이러스 약물로서 사용된다. 뉴라미니다제 저해제가 현재 인플루엔자 바이러스 감염 치료에 선호되는데 이 약은 독성이 거의 없고 매우 효과적이기 때문이다. 미국 질병 통제 예방 센터는 2005-2006년 동안의 인플루엔자 시즌에 M2 저해제보다는 뉴라미니다제 저해제를 처방할 것을 권고했는데 그 이유는 높은 레벨의 약물 내성 때문이었다. 임신한 여성의 경우 일반인보다는 2009년 H1N1 바이러스에 의해 더 심각한 영향을 받을 것으로 보이기 때문에 항인플루엔자 약물을 즉각 처방하는 것이 권고된다. 뉴라미니다제 저해제 오셀타미비르(상업명 타미플루)와 자나미비르(상업명 릴렌자)와 같은 뉴라미니다제 저해제가 몸에서 바이러스가 퍼지는 것을 막기 위해 설계된 약물들이다. 이러한 약물들은 인플루엔자 바이러스 A, B 모두에 대해서 효과가 있다. 서로 다른 인플루엔자 바이러스주들이 이들 항바이러스 약물들에 대해서 다른 정도의 내성을 보인다. M2 저해제 항바이러스 약물인 아만타다인(amantadine)과 리만타다인(rimantadine)은 바이러스 이온 채널(M2 단백질)을 저해하고 바이러스가 세포를 감염시키는 것을 막는다. 이러한 약물들은 감염 초기에 처방된다면 때때로 인플루엔자 바이러스 A에 대해서 효과적이다. 하지만 인플루엔자 바이러스 B에 대해서는 효과가 없다. 그 이유는 인플루엔자 B 바이러스의 M2 단백질은 타입 A 바이러스의 M2 단백질과 구조적으로 달라서 아만타다인이 결합하지 않기 때문이다. 미국에서 얻어진 H3N2의 아만타다인과 리만타다인에 대한 측정된 내성도는 2005년에 91% 증가하였다. 높은 수준의 내성은 중국과 러시아 등지에서 처방전 없이 팔리는 감기약 중에서 아만타다인이 가장 쉽게 사용되기 때문일 수 있다. 그리고 농장에서 인플루엔자를 막기 위해서 아만타다인이 가금류에게 쉽게 사용되기 때문일 수도 있다.Two classes of antiviral drugs are used to treat influenza. Neuraminidase inhibitors and M2 protein inhibitors (adamantane derivatives) are used as antiviral drugs. A neuraminidase inhibitor is currently preferred for the treatment of influenza virus infections because it is highly toxic and highly effective. The US Centers for Disease Control recommends prescribing a neuraminidase inhibitor for influenza season 2005-2006 rather than an M2 inhibitor because of high levels of drug resistance. Since pregnant women are likely to be more affected by the 2009 H1N1 virus than the general population, it is recommended that an immediate anti-influenza drug be prescribed. Neuraminidase Inhibitors Neuraminidase inhibitors such as oseltamivir (commercial name Tamiflu) and zanamivir (commercial name Lilenga) are drugs designed to prevent the spread of the virus in the body. These drugs are effective against both influenza viruses A and B. Different influenza virus strains show different degrees of resistance to these antiviral drugs. M2 inhibitors The antiviral drugs amantadine and rimantadine inhibit the viral ion channel (M2 protein) and prevent the virus from infecting cells. These drugs are sometimes effective against influenza virus A if they are prescribed early in the infection. However, it is not effective against influenza virus B. This is because the M2 protein of influenza B virus is structurally different from the M2 protein of the type A virus and does not bind amantadine. The measured tolerance of amantadine and rimantadine of H3N2 in the United States increased by 91% in 2005. The high level of tolerance may be due to the fact that Amantadine is the easiest to use among prescription cold medicines sold in China and Russia. And it may be because Amantadine is easily used by poultry to prevent influenza on the farm.
따라서 기존 항바이러스 약물에 의한 내성을 극복할 수 있는 새로운 치료제 개발은 지속적으로 필요하다. Therefore, there is a continuing need to develop new therapeutic agents that can overcome resistance by existing antiviral drugs.
