- Non-Patent Document 1 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 September 10, 2021, the number of confirmed infected people will reach 220 million or more, and the number of deaths will reach 4.6 million 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.
- the spike (S) protein expressed on the surface of the coronavirus is an essential molecule for virus entry into cells.
- the S protein is composed of S1 and S2 regions, and the S1 region is an essential region for binding to angiotensin-converting enzyme 2 (ACE2) expressed on the surface of host cells.
- the S2 region contains multiple cleavage sites by host proteases such as transmembrane protease, serine 2 (TMPRSS2), furin and cathepsin, and is an essential region for the fusion of the viral membrane and the cell membrane.

Abstract
Description
本発明は、コロナウイルス増殖阻害活性を示す化合物、および/またはコロナウイルス増殖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 a compound exhibiting coronavirus growth-inhibitory activity and/or a pharmaceutical composition containing a compound exhibiting coronavirus growth-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。2021年9月10日時点で確認された感染者数は2.2億人以上、死者数は460万人以上に達する(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 September 10, 2021, the number of confirmed infected people will reach 220 million or more, and the number of deaths will reach 4.6 million 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.
COVID-19に対する治療薬として、既存薬のドラッグリポジショニングが検討されているが、明確な有効性は認められていない。また、ウイルスのRNAポリメラーゼを阻害する静脈内注射薬レムデシビルが2020年5月7日に日本で緊急承認されたが、そ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。従って、COVID-19に対する治療薬の創製は急務である。 Although drug repositioning of existing drugs is being considered as a therapeutic agent for COVID-19, no clear efficacy has been confirmed. In addition, remdesivir, an intravenous drug that inhibits viral RNA polymerase, received emergency approval in Japan on May 7, 2020, but sufficient evidence has not been obtained regarding its efficacy and safety. Therefore, there is an urgent need to create therapeutic agents against COVID-19.
コロナウイルス表面に発現するスパイク(S)タンパク質は細胞へのウイルス侵入に必須な分子である。Sタンパク質はS1およびS2領域から構成され、S1領域は宿主細胞の表面に発現するangiotensin-converting enzyme 2(ACE2)との結合に必須な領域である。S2領域にはtransmembrane protease,serine 2(TMPRSS2)、furinおよびcathepsin等の宿主プロテアーゼによる切断部位が複数存在し、ウイルス膜と細胞膜との融合に必須な領域である。Sタンパク質は創薬ターゲット分子の1つとして注目されており、これまでに、Sタンパク質をターゲットとした複数の抗体医薬品が米国にて緊急使用許可(EUA)を取得している。 The spike (S) protein expressed on the surface of the coronavirus is an essential molecule for virus entry into cells. The S protein is composed of S1 and S2 regions, and the S1 region is an essential region for binding to angiotensin-converting enzyme 2 (ACE2) expressed on the surface of host cells. The S2 region contains multiple cleavage sites by host proteases such as transmembrane protease, serine 2 (TMPRSS2), furin and cathepsin, and is an essential region for the fusion of the viral membrane and the cell membrane. The S protein is attracting attention as one of drug discovery target molecules, and so far, a plurality of antibody drugs targeting the S protein have obtained Emergency Use Authorization (EUA) in the United States.

本発明化合物を本質的に上記のとおり試験した。本発明化合物(I-0011)の結果を以下に示す。
試験例3:SARS-CoV-2感染マウスモデルを用いた薬効評価 (ウイルス増殖抑制効果の確認)
(1)ウイルス株
SARS-CoV-2 MA-P10 (JPN/TY/WK-521株を元とし、マウス肺で10継代したもの)
(2)実験動物
BALB/cマウス、雌性、5週齢
(3)評価方法
SARS-CoV-2 MA-P10を2×102 TCID50/50μLとなるようにPBS(-)で希釈し、調製したウイルス液を50μLずつマウスに経鼻接種した。感染24時間後および36時間後に、本発明化合物を50μLずつマウスに経鼻投与し、感染48時間後の肺内ウイルス力価を測定した。
(結果)
本発明化合物を本質的に上記のとおり試験した。
媒体であるPBS(-)を投与した群では、投与翌日の肺内ウイルス力価は2.6×107 TCID50/mL程度であった。一方で、本発明化合物(I-0011)を投与した場合は投与用量依存的な肺内ウイルス力価減少がみられ、1.5 mg/kg、0.5 mg/kg、0.15 mg/kg投与群においてそれぞれ媒体投与群と比較して約5.8 log10、5.1 log10、2.6 log10の肺内ウイルス力価減少がみられた。このことから本発明化合物投与群では、媒体投与群に比べて肺内ウイルス力価を減少させることが示された(図1)。
Test Example 3: Efficacy evaluation using a SARS-CoV-2 infected mouse model (confirmation of virus growth inhibitory effect)
(1) virus strain
SARS-CoV-2 MA-P10 (based on JPN/TY/WK-521 strain, passaged 10 times in mouse lung)
(2) Experimental animals
BALB/c mice, female, 5 weeks old (3) Evaluation method
SARS-CoV-2 MA-P10 was diluted with PBS(-) to 2×10 2 TCID 50 /50 μL, and 50 μL of the prepared virus solution was intranasally inoculated to mice. At 24 hours and 36 hours after infection, 50 μL of the compound of the present invention was intranasally administered to mice, and the lung virus titer was measured at 48 hours after infection.
(result)
The compounds of the invention were tested essentially as described above.
In the group administered with PBS(-) as a vehicle, the pulmonary virus titer on the day after administration was approximately 2.6×10 7 TCID 50 /mL. On the other hand, when the compound of the present invention (I-0011) was administered, a dose-dependent reduction in the pulmonary virus titer was observed. Approximately 5.8 log 10 , 5.1 log 10 , and 2.6 log 10 reductions in pulmonary viral titers were observed compared to treatment groups. From this, it was shown that the intrapulmonary virus titer was reduced in the compound-administered group of the present invention compared to the vehicle-administered group (Fig. 1).
試験例4:SARS-CoV-2感染マウスモデルを用いた薬効評価 (致死抑制効果の確認)
(1)ウイルス株
SARS-CoV-2 MA-P10 (JPN/TY/WK-521株を元とし、マウス肺で10継代したもの)
(2)実験動物
BALB/cマウス、雌性、30-50週齢
(3)評価方法
SARS-CoV-2 MA-P10を2×102 TCID50/50μLとなるようにPBS(-)で希釈し、調製したウイルス液を50μLずつマウスに経鼻接種した。感染24時間後(QD)もしくは感染24時間後および36時間後(BID)に、本発明化合物を50μLずつマウスに経鼻投与した。感染10日後までの生存率および体重変動を測定した。
(結果)
本発明化合物を本質的に上記のとおり試験した。
媒体であるPBS(-)を投与した群では、感染6日後の時点で全個体が死亡し、感染10日後の生存率は0%であった。一方で、本発明化合物(I-0011)を投与した場合、0.5 mg/kgおよび1.5 mg/kgをそれぞれQDまたはBIDで単日投与したいずれの群においても、感染10日後の生存率は100%であった。このことから本発明化合物投与群では、媒体投与群に対して生存率が改善した(図2)。また媒体投与群では、感染5日後の時点で初期体重に比べて20%以上の体重減少がみられた。一方で、本発明化合物を投与した場合、初期体重に比べて15%程度までの体重減少でとどまり、その後体重の回復傾向がみられた。このことから本発明化合物投与群では、媒体投与群に比べて、感染に伴う体重減少の抑制効果がみられた(図3)。
若齢マウスと比較すると、加齢マウスでは、感染源から身体を防御し、それらを排除する正常な免疫応答が低下しており、ウイルス感染により致死に至ることが想定される。しかしながら、上記に示す通り、加齢マウスを用いたSARS-CoV-2感染マウスモデルにおいて、本発明化合物(I-0011)の投与により、感染10日後のマウスの生存率は100%を示した。加齢マウスを用いた非臨床試験は、基礎疾患を有するハイリスク患者が重症化に至る過程を模した非臨床評価系の一つとして位置づけられるため、重症化リスクの高い患者に対する治療オプションとして、本発明化合物(I-0011)の有用性を支持する。
また、上記試験結果は、本発明化合物投与群においてウイルス感染による重症化が抑制されたことを示唆しており、本発明化合物(I-0011)のSARS-CoV-2に対する抗ウイルス効果のみならず、SARS-CoV-2による感染症の重症化抑制用医薬としての有用性を支持する。
