As of August 22, 2022, the confirmed number of infected people reached 590 million or more, and the number of deaths reached 6,450,000 or more (Non-Patent Document 1). Droplet infection, contact infection and aerosol infection have been reported as the main infection routes of SARS-CoV-2. (Non-Patent Document 2). The incubation period is about 2 to 14 days, and cold-like symptoms such as fever (87.9%), dry cough (67.7%), malaise (38.1%), and phlegm (33.4%) are typical. (Non-Patent Document 3).

  • Coronaviruses synthesize two polyproteins when they infect cells. These two polyproteins contain a structural protein for creating new virus particles, a replication complex for creating the viral genome, and two proteases.

Of the two proteases, 3CL protease (main protease) is responsible for most of the polyprotein cleavage (Non-Patent Document 4). For COVID-19 therapeutics targeting 3CL protease, in June 2021, Pfizer completed a Phase 1b trial of Lufotrelvir (PF-07304814), a prodrug of PF-00835231, at ClinicalTrials.

 本発明は、コロナウイルス3CLプロテアーゼ阻害活性を示す化合物、およびコロナウイルス3CLプロテアーゼ阻害活性を示す化合物を含有する医薬組成物に関する。 The present invention relates to compounds exhibiting coronavirus 3CL protease inhibitory activity and pharmaceutical compositions containing compounds exhibiting coronavirus 3CL protease inhibitory activity.
 ニドウイルス目コロナウイルス科オルトコロナウイルス亜科に属するコロナウイルスは、約30キロベースのゲノムサイズを有し、既知のRNAウイルスでは最大級の一本鎖+鎖RNAウイルスである。コロナウイルスはアルファコロナウイルス属、ベータコロナウイルス属、ガンマコロナウイルス属およびデルタコロナウイルス属の4つに分類され、ヒトに感染するコロナウイルスとして、アルファコロナウイルス属の2種類(HCoV-229E、HCoV-NL63)およびベータコロナウイルス属の5種類(HCoV-HKU1、HCoV-OC43、SARS-CoV、MERS-CoV、SARS-CoV-2)の計7種類が知られている。この内、4種類(HCoV-229E、HCoV-NL63、HCoV-HKU1、HCoV-OC43)は風邪の病原体であるが、残りの3種類は重症肺炎を引き起こす重症急性呼吸器症候群(SARS)コロナウイルス(SARS-CoV)、中東呼吸器症候群(MERS)コロナウイルス(MERS-CoV)および新型コロナウイルス(SARS-CoV-2)である。 The coronavirus, which belongs to the subfamily Orthocoronavirus subfamily, Coronaviridae, order of the Nidoviridae, has a genome size of about 30 kilobases, and is the largest single-stranded + stranded RNA virus among known RNA viruses. Coronaviruses are classified into four genera: Alphacoronavirus, Betacoronavirus, Gammacoronavirus, and Deltacoronavirus, and there are two types of coronaviruses that infect humans: Alphacoronavirus (HCoV-229E, HCoV-229E, HCoV -NL63) and five members of the genus Betacoronavirus (HCoV-HKU1, HCoV-OC43, SARS-CoV, MERS-CoV, SARS-CoV-2). Of these, four (HCoV-229E, HCoV-NL63, HCoV-HKU1, HCoV-OC43) are pathogens of the common cold, while the remaining three are severe acute respiratory syndrome (SARS) coronaviruses that cause severe pneumonia ( SARS-CoV), Middle East respiratory syndrome (MERS) coronavirus (MERS-CoV) and novel coronavirus (SARS-CoV-2).
 2019年12月に中国武漢で発生した新型コロナウイルス感染症(COVID-19)は急速に国際社会に蔓延し、2020年3月11日にWHOよりパンデミックが表明された。2022年8月22日時点で確認された感染者数は5.9億人以上、死者数は645万人以上に達する(非特許文献1)。SARS-CoV-2の主な感染経路として飛沫感染、接触感染およびエアロゾル感染が報告されており、SARS-CoV-2は3時間程度エアロゾルと共に空気中を漂い続け、感染力を維持することが確認されている(非特許文献2)。潜伏期間は2~14日程度であり、発熱(87.9%)、空咳(67.7%)、倦怠感(38.1%)、痰(33.4%)等の風邪様症状が典型的である(非特許文献3)。重症例では、急性呼吸窮迫症候群や急性肺障害、間質性肺炎等による呼吸器不全が起こる。また、腎不全や肝不全などの多臓器不全も報告されている。 The novel coronavirus disease (COVID-19) that broke out in Wuhan, China in December 2019 spread rapidly throughout the international community, and was declared a pandemic by the WHO on March 11, 2020. As of August 22, 2022, the confirmed number of infected people reached 590 million or more, and the number of deaths reached 6,450,000 or more (Non-Patent Document 1). Droplet infection, contact infection and aerosol infection have been reported as the main infection routes of SARS-CoV-2. (Non-Patent Document 2). The incubation period is about 2 to 14 days, and cold-like symptoms such as fever (87.9%), dry cough (67.7%), malaise (38.1%), and phlegm (33.4%) are typical. (Non-Patent Document 3). In severe cases, respiratory failure due to acute respiratory distress syndrome, acute lung injury, interstitial pneumonia, etc. occurs. Multiple organ failure such as renal failure and liver failure has also been reported.
 既存薬のドラッグリポジショニングから、抗ウイルス薬であるレムデシビル、抗炎症薬であるデキサメタゾン、リウマチ薬であるバリシチニブがCOVID-19に対する治療薬として承認され、2022年1月に抗IL-6受容体抗体であるトシリズマブが追加承認されている。また、2021年7月に、抗体カクテル療法であるロナプリーブが特例承認され、2021年9月にソトロビマブが特例承認され、2021年12月にモルヌピラビルが特例承認された。これらの薬剤についての有効性や安全性については、十分なエビデンスが得られていない。したがって、COVID-19に対する治療薬、特に経口薬の創製は急務である。 From the drug repositioning of existing drugs, the antiviral drug remdesivir, the anti-inflammatory drug dexamethasone, and the rheumatism drug baricitinib were approved as therapeutic agents for COVID-19, and anti-IL-6 receptor antibodies were approved in January 2022. Tocilizumab has been additionally approved. In addition, in July 2021, special approval was granted for the antibody cocktail therapy lonaprive, in September 2021, special approval was granted for sotrovimab, and in December 2021, special approval was granted for molnupiravir. Sufficient evidence has not been obtained regarding the efficacy and safety of these drugs. Therefore, there is an urgent need to create therapeutic drugs, especially oral drugs, against COVID-19.
 コロナウイルスは、細胞に感染すると、2つのポリタンパク質を合成する。この2つのポリタンパク質中には、新たなウイルス粒子を作り出すための構造タンパク質、ウイルスゲノムを作る複製複合体、2つのプロテアーゼが含まれている。プロテアーゼは、ウイルスから合成されたポリタンパク質を切断し、それぞれのタンパク質を機能させるために不可欠な働きをする。2つのプロテアーゼのうち、ポリタンパク質の切断のほとんどを担うのが、3CLプロテアーゼ(メインプロテアーゼ)である(非特許文献4)。
 3CLプロテアーゼを標的とした、COVID-19治療薬としては、2021年6月、Pfizer社によるPF-00835231のプロドラッグであるLufotrelvir(PF-07304814)のPhase1b試験の完了がClinicalTrials.govに掲載された(NCT04535167)。また、2021年3月、Pfizer社は新型コロナウイルス感染症に対する治療薬PF-07321332のPhase1試験を開始すると発表した。PF-00835231、LufotrelvirおよびPF-07321332の構造式は以下に示す通りで、本発明化合物とは化学構造が異なる(非特許文献5、9および10、ならびに特許文献3および4)。

 2021年12月、ニルマトレルビル(PF-07321332)錠/リトナビル錠であるPAXLOVID(TM)は、米国で緊急使用許可が承認され、2022年2月10日にパキロビッド(登録商標)パックが日本で特例承認された。
Coronaviruses synthesize two polyproteins when they infect cells. These two polyproteins contain a structural protein for creating new virus particles, a replication complex for creating the viral genome, and two proteases. Protease plays an essential role in cleaving polyproteins synthesized from viruses and allowing each protein to function. Of the two proteases, 3CL protease (main protease) is responsible for most of the polyprotein cleavage (Non-Patent Document 4).
For COVID-19 therapeutics targeting 3CL protease, in June 2021, Pfizer completed a Phase 1b trial of Lufotrelvir (PF-07304814), a prodrug of PF-00835231, at ClinicalTrials. gov (NCT04535167). Also, in March 2021, Pfizer announced that it will begin Phase 1 trials of PF-07321332, a treatment for COVID-19. The structural formulas of PF-00835231, Lufotrelvir and PF-07321332 are shown below, and differ in chemical structure from the compounds of the present invention (Non-Patent Documents 5, 9 and 10, and Patent Documents 3 and 4).

 また、3CLプロテアーゼを標的とした、COVID-19治療薬としては、2021年8月、Pardes Biosciences社によるPBI-0451のPhase1試験の開始がClinicalTrials.govに掲載された(NCT05011812)。PBI-0451の構造式は以下に示す通りで、本発明化合物とは化学構造が異なる(非特許文献11)。

 3CLプロテアーゼを標的としたCOVID-19治療薬に対する耐性変異については、十分なエビデンスが得られていない。 Sufficient evidence has not been obtained for resistance mutations to COVID-19 therapeutic drugs that target 3CL protease.
