Description

헤테로아릴 유도체 화합물의 항바이러스 용도 Antiviral use of heteroaryl derivative compounds
본 발명은 헤테로아릴 유도체 화합물 및 이의 의약적 용도에 관한 것이다. 구체적으로, 본 발명은 ANO6 억제 활성을 갖는 헤테로아릴 유도체 화합물의 항바이러스 용도에 관한 것이다.The present invention relates to heteroaryl derivative compounds and their medicinal uses. Specifically, the present invention relates to the antiviral use of heteroaryl derivative compounds with ANO6 inhibitory activity.
코로나 바이러스는 바이러스 외피를 숙주 세포와 결합하여 바이러스 게놈을 숙주 세포로 전달하는 외피 RNA 바이러스이며, 중증 급성 호흡기 증후군 코로나 바이러스 2(SARS-CoV-2), 코로나 바이러스 감염증(COVID-19)의 원인 물질이다. 베타-코로나 바이러스(β-Coronavirus) 속에 속하는 코로나 바이러스는 비리온 외피를 가지고 있으며, 클래스 I 바이러스 융합 단백질인 스파이크(S) 당단백질을 가지고 있다. SARS-CoV-2의 S 단백질은 세포 친화성의 주요 결정 인자이며 막 융합 과정의 초기 단계를 구성하는 숙주 세포의 바이러스 진입 수용체인 안지오텐신 전환효소 2(ACE2)에 대한 결합을 매개한다. 그러나, 바이러스와 숙주 세포막 융합 과정은 아직 완전히 밝혀지지 않았다.Coronavirus is an enveloped RNA virus that combines the viral envelope with a host cell to transfer the viral genome to the host cell, and is the causative agent of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and coronavirus infection (COVID-19). am. Coronaviruses belonging to the genus β-Coronavirus have a virion envelope and the spike (S) glycoprotein, a class I virus fusion protein. The S protein of SARS-CoV-2 is a key determinant of cell tropism and mediates binding to angiotensin-converting enzyme 2 (ACE2), a viral entry receptor on host cells that constitutes the initial step of the membrane fusion process. However, the process of virus and host cell membrane fusion has not yet been fully elucidated.
TMEM16F로 알려진 아녹타민-6(ANO6)은 Ca2+-활성화 Cl-채널 (CACC) 및 Ca2+ 의존성 인지질 스크렘블레이즈로서 기능하는 세포막 단백질이다. 포스파티딜세린은 음이온성 인지질로, 주로 정상 조건에서 대부분 세포막의 내부 소엽에서 발견된다. 원형질막의 외부 표면에서 포스파티딜세린의 노출은 혈소판 응집, 선천적 면역 및 세포 사멸과 같은 다양한 생리학적 및 병리학적 역할을 한다. 이러한 포스파티딜세린의 세포 표면에서의 외부화는 막의 포스파티딜세린의 비대칭을 만드는 지질 플립파아제의 비활성화 또는 음이온성 인지질의 전위를 향상시키는 ANO6과 같은 인지질 스크렘블레이즈의 활성화에 의해 매개된다. 특히, 많은 연구에서 포스파티딜세린의 세포 표면 노출이 포유류 세포막뿐 아니라 막 융합과 관련되어 있음이 밝혀졌는데, 근관 형성과 같은 포유동물 세포막뿐 아니라 바이러스 외피와 숙주 세포막 사이의 막 융합과 연관되어 바이러스가 숙주 세포로 들어가는 것을 촉진한다.Anoctamine-6 (ANO6), known as TMEM16F, is a cell membrane protein that functions as a Ca 2+ -activated Cl - channel (CACC) and Ca 2+ -dependent phospholipid scramblase. Phosphatidylserine is an anionic phospholipid, found primarily in the inner leaflets of most cell membranes under normal conditions. Exposure of phosphatidylserine at the outer surface of the plasma membrane has various physiological and pathological roles, such as platelet aggregation, innate immunity, and cell death. This externalization of phosphatidylserine from the cell surface is mediated by inactivation of lipid flippase, which creates asymmetry of phosphatidylserine in the membrane, or activation of phospholipid scramblases such as ANO6, which enhances the translocation of anionic phospholipids. In particular, many studies have shown that cell surface exposure of phosphatidylserine is associated with membrane fusion not only in mammalian cell membranes, such as myotube formation, but also between the viral envelope and the host cell membrane, allowing the virus to interact with the host. Promotes entry into cells.
따라서, 아녹타민-6 활성 저해제 개발을 통해 아녹타민-6의 이온 채널 및 인지질 스크렘블레이즈로서의 기능이 관여하는 바이러스 감염 질환 또는 바이러스 감염 관련 질환을 효과적으로 개선 또는 치료할 수 있는 의약품의 개발이 요구된다.Therefore, there is a need for the development of pharmaceuticals that can effectively improve or treat viral infectious diseases or viral infection-related diseases involving the functions of anoctamine-6 as an ion channel and phospholipid scrambler through the development of anoctamin-6 activity inhibitors.
이러한 배경 하에서, 본 발명자들은 숙주 세포막에서 ANO6 매개 포스파티딜세린의 외부화가 외피 바이러스의 침입에 관여한다는 것을 발견하였고, 아녹타민-6 활성 저해제의 항 바이러스 용도에 관하여 본 발명을 완성하였다.Under this background, the present inventors discovered that ANO6-mediated externalization of phosphatidylserine in the host cell membrane is involved in the invasion of enveloped viruses, and completed the present invention regarding the antiviral use of anoctamin-6 activity inhibitor.

Solid feed for laboratory animals (Teklad Certified Irradiated Global 18% Protein Rodent Diet 2918C, Envigo RMS, Inc., U.S.A.) was placed in a feeder and consumed ad libitum.
최종검역 후, 순위화한 체중 측정 결과에 따라 각 군의 평균 체중이 최대한 균일하게 분포되도록 군분리하였으며, 군분리 후 잔여동물은 본시험에서 제외시키고, 이산화탄소(CO 2) 가스를 흡입시켜 안락사시켰다. After the final quarantine, the animals were separated into groups so that the average weight of each group was distributed as evenly as possible according to the ranked weight measurement results. After group separation, the remaining animals were excluded from the main test and euthanized by inhaling carbon dioxide (CO 2 ) gas. .
