중증급성 호흡 증후군은 사스-코로나 바이러스(SARS coronavirus, SARS-CoV)가 인간의 호흡기를 침범하여 발생하는 전염병으로 갑작스런 발열, 기침, 호흡곤란이 주 증상이다. 폐렴으로 진행돼 죽음에 이를 수도 있다. 2002년 11월 중국 남부 광둥(廣東)성에서 발생, 홍콩을 거쳐 벨기에를 제외한 유럽 각국과 미국·캐나다 등 북아메리카, 그리고 한국·일본을 제외한 아시아 각국 등 세계 32개국에서 83,000여 명이 감염되었으며, 이 중 10%가 사망하였다. 세계보건기구(WHO)는 사스의 원인병원체를 변종 코로나바이러스로 밝힌 바 있는데, 코로나바이러스는 사람에게서는 경증 또는 중증의 상부 호흡기 질병을 일으키고 동물에게서는 호흡기, 위장관, 간, 신경질환을 일으키는 바이러스다. 코로나 바이러스는 한 가닥의 RNA를 유전물질로 가지고 있는 바이러스이다. 인간에게 감염을 일으키는 형태는 제1혈청형과 제2혈청형이 주로 알려져 있으며, 다른 새로운 종류인 것도 나타나고 있어 새로운 변종의 발생에 대한 예방 및 치료 방법이 필요하다. 바이러스가 전파되는 경로는 아직 완전히 밝혀지지 않았지만 대기 중에 떠다니는 고체나 액체의 미세한 입자에 의해 전파되는 것으로 추측하고 있다. 바이러스인 사스-코로나 바이러스에 노출된 후 2~7일 정도의 잠복기가 지나면 발열, 무력감, 두통, 근육통의 신체 전반에 걸친 증상이 나타난다. 이후 기침과 호흡 곤란 증상이 발생하고 25%의 환자에게서 설사가 동반된다. 심한 경우에는 증상이 2주 이상 지속되며 호흡 기능이 크게 나빠지고 급성 호흡곤란 증후군 및 다기관 부전증으로 진행된다. 사스에 특이적인 치료법은 없다. Severe acute respiratory syndrome is an infectious disease caused by the SARS coronavirus (SARS-CoV) invading the human respiratory system. The main symptoms are sudden fever, cough, and difficulty breathing. It can lead to pneumonia and lead to death. Outbreaks in Guangdong Province in southern China in November 2002, and 83,000 people were infected in 32 countries around the world including Europe excluding Belgium, North America such as the United States and Canada, and Asian countries excluding Korea and Japan through Hong Kong. 10% died. The World Health Organization (WHO) has identified the causative agent of SARS as a variant coronavirus, which causes mild or severe upper respiratory disease in humans and respiratory, gastrointestinal, liver, and neurological diseases in animals. Coronavirus is a virus that has a single strand of RNA as genetic material. As for the forms that cause infection in humans, the first and second serum types are mainly known, and other new types are also appearing, so a method of preventing and treating the occurrence of new strains is required. The path through which the virus spreads is not yet fully known, but it is speculated that it is transmitted by fine particles of solid or liquid floating in the atmosphere. After 2 to 7 days of incubation period after exposure to the virus, SARS-corona virus, fever, weakness, headache, and muscle pain appear throughout the body. Afterwards, coughing and shortness of breath occur, and diarrhea is accompanied in 25% of patients. In severe cases, symptoms persist for more than 2 weeks, respiratory function is greatly deteriorated, and acute respiratory distress syndrome and multi-organ insufficiency develop. There is no specific treatment for SARS.

사스-코로나바이러스의 게놈(유전체) 서열분석 결과, 다른 종류의 코로나바이러스의 복제 활성에 필수적인 단백질분해효소 (protease)와 서열이 매우 유사한 3CL pro의 존재가 밝혀졌다.

J Virol 2001;75:6676-81.]As a result of genomic (genetic) sequencing of SARS-coronavirus, it was found that the existence of 3CL pro is very similar in sequence to protease, which is essential for the replication activity of other coronaviruses.

바이러스의 다단백질 (polyprotein)이 합성된 후 단백질분해효소에 의해 절단되어 각각 독립된 단백질로서 기능을 하게 된다. 이러한 과정은 코로나 바이러스의 복제 주기에 핵심적인 과정으로 바이러스의 단백질분해효소(protease)에 의해 일어난다. SARS-CoV 3CL 프로테아제는 피코나바이러스과(Picornaviridae)의 3C 프로테아제의 명칭을 따라 명명되었으며, 복제효소(replicase) 유전자에 의해 암호화된 다단백질(polyprotein)의 11개 절단부위을 인식, 절단하는 단백질분해효소이다[Yi-Ming Shao, Wen-Bin Yang, Hung-Pin Peng,Min-Feng Hsu, Keng-Chang Tsai, Tun-Hsun Kuo, Andrew H.-J. Wang, Po-Huang Liang, Chun-Hung Lin, An-Suei Yang, and Chi-Huey Wong. Structure-Based Design and Synthesis of Highly Potent SARS-CoV 3CL Protease Inhibitors.ChemBioChem 2007, 8, 1654 1657]. 또한 3CL pro는 코로나바이러스 복제 활성을 조절하는 중요 단백질분해효소로서 핵심 단백질 분해효소 (main protease)로 불린다. After the virus polyprotein is synthesized, it is cleaved by proteolytic enzymes to function as independent proteins. This process is a key process in the replication cycle of the corona virus and is caused by the viral protease. SARS-CoV 3CL protease is named after the name of the 3C protease of the family Picornaviridae , and is a protease that recognizes and cuts 11 cleavage sites of polyproteins encoded by the replicase gene. [Yi-Ming Shao, Wen-Bin Yang, Hung-Pin Peng, Min-Feng Hsu, Keng-Chang Tsai, Tun-Hsun Kuo, Andrew H.-J. Wang, Po-Huang Liang, Chun-Hung Lin, An-Suei Yang, and Chi-Huey Wong. Structure-Based Design and Synthesis of Highly Potent SARS-CoV 3CL Protease Inhibitors. Chem Bio Chem 2007, 8, 1654 1657]. In addition, 3CL pro is an important protease that regulates coronavirus replication activity and is called the main protease.

(1) 재조합 사스-코로나 바이러스 3(1) Recombinant SARS-coronavirus 3 CLCL 프로테아제에 대한 활성 조사 Protease activity investigation

사스-코로나 바이러스 3CL 프로테아제 분석에 이용되는 기질은 사스-코로나 바이러스 복제효소(SARS-CoV replicase) 유전자에 의해 합성된 다단백질 (pp1ab)에 존재하는 절단 부위를 모방하여 디자인된 합성 펩타이드(DABCYL-Lys-Thr-Ser-Ala-Val-Leu-Gln-Ser-Gly-Phe-Arg-Lys-Met-Glu-EDANS ,Bachem, 스위스)이다. 이 기질에는 형광 도너인 EDANS와 형광 소멸자인 DABCYL이 결합되어 있다[Matayoshi, E.D., Wang, G.T., Kraff, G.A. and Erickson, J. Novel fluorogenic substrates for assaying retroviral proteases by resonance energy transfer. Science. 247: 954-958(1990)]. 형광은 기질이 절단되어 EDANS 그룹이 DABCYL 그룹으로부터 분리되었을 때만 확인이 된다[Luker, K.E., Francis, S.E., Gluzman, I.Y. and Goldberg. Kinetic analysis of plasmepsin I and II aspartic protease of the Plasmodium falciparum digestive vacuole. Mol. Biochem. Parasitol. 79:71-78(1996)]. The substrate used in the SARS-corona virus 3CL protease assay is a synthetic peptide (DABCYL-Lys) designed by mimicking the cleavage site present in the polyprotein (pp1ab) synthesized by the SARS-CoV replicase gene. -Thr-Ser-Ala-Val-Leu-Gln-Ser-Gly-Phe-Arg-Lys-Met-Glu-EDANS, Bachem, Switzerland). The fluorescent donor EDANS and the fluorescence deactivator DABCYL are bound to this substrate [Matayoshi, E.D., Wang, G.T., Kraff, G.A. and Erickson, J. Novel fluorogenic substrates for assaying retroviral proteases by resonance energy transfer. Science. 247: 954-958 (1990)]. Fluorescence is confirmed only when the substrate is cleaved and the EDANS group is separated from the DABCYL group [Luker, K.E., Francis, S.E., Gluzman, I.Y. and Goldberg. Kinetic analysis of plasmepsin I and II aspartic protease of the Plasmodium falciparum digestive vacuole. Mol. Biochem. Parasitol. 79:71-78 (1996)].

재조합 사스-코로나 바이러스 3CL 프로테아제의 활성을 확인하기 위하여, 기질을 최종농도20 μM 농도로 20 mM Tris 완충액(pH 7.5)에 녹여 사용하였다. 상기 실시예 4에서 수득한 재조합 사스-코로나 바이러스 3CL 프로테아제 3㎍을 45종의 저해 활성 후보물질(최종농도 100 μM)과 혼합하여 25℃에서 25분 반응시킨 후, 반응 산물은 형광 마이크로 플레이트 리더 SpectraMax Gemini XPS (Molecular Devices, USA) 기기를 이용하여 형광 세기(흡수(exitation) 355 nm, 방출(emission) 538 nm)를 측정하여 모니터 하였다. 사스-코로나 바이러스 3CL 프로테아제에 의해 기질이 분해됨에 따라 형광세기가 증가하게 되는데 이를 이용하여 저해 후보물질들에 대한 활성저해를 측정하였다.In order to confirm the activity of the recombinant SARS-coronavirus 3CL protease, the substrate was dissolved in 20 mM Tris buffer (pH 7.5) at a final concentration of 20 μM and used. 3 μg of the recombinant SARS-coronavirus 3CL protease obtained in Example 4 was mixed with 45 inhibitory activity candidates (final concentration 100 μM) and reacted at 25° C. for 25 minutes, and the reaction product was a fluorescent microplate reader SpectraMax. The fluorescence intensity (exitation 355 nm, emission 538 nm) was measured and monitored using a Gemini XPS (Molecular Devices, USA) instrument. As the substrate is degraded by the SARS-corona virus 3CL protease, the fluorescence intensity increases, and the activity inhibition of the inhibitory candidates was measured using this.

재조합 사스-코로나 바이러스 3CL 프로테아제 활성 저해를 비교하기 위하여, 저해 활성 물질 첨가 없이 단지 재조합 사스-코로나 바이러스 3CL 프로테아제와 기질만을 포함하는 반응액을 대조군으로 사용하였다.In order to compare the inhibition of the recombinant SARS-coronavirus 3CL protease activity, a reaction solution containing only the recombinant SARS-corona virus 3CL protease and substrate was used as a control without addition of an inhibitory active substance.

54종의 활성 저해 후보물질 중 우수한 활성저해를 나타내는 화합물을 선별하고자 하였고 하기 표 1에 화학물질들의 명칭 및 상대적 활성저해를 나타내었다. 활성 저해의 기준은 저해 활성 물질을 첨가하지 않았을 때의 재조합 사스-코로나 바이러스 3CL 프로테아제의 활성저해를 0%라 하고 화합물 첨가 후의 저해 효과에 의해 나타나는 활성을 %로 표시하였다. 즉 더 높은 %의 수치는 더 높은 효소 저해 특성을 나타낸다.It was attempted to select a compound that exhibits excellent activity inhibition among 54 candidates for activity inhibition, and the names and relative activity inhibition of the chemical substances are shown in Table 1 below. As a criterion for inhibition of activity, inhibition of the activity of the recombinant SARS-coronavirus 3CL protease when the inhibitory active substance was not added was 0%, and the activity exhibited by the inhibitory effect after addition of the compound was expressed in %. In other words, higher percentage values indicate higher enzyme inhibitory properties.
