Abstract
Description
도 1a KD025가 키나제-리간드(kinase-ligand) 결합을 감소시키고 남아있는 결합(binding) 활성을 플롯팅(plotting)한 도이다.
도 1b 결합 활성이 크게 저해되어 잔존활성이 적은 (≤ 10 %) 키나제(kinase)를 순위별로 나열하고 잔존 리간드(ligand) 결합(binding) 활성을 나타낸 도이다.
도 1c 468 개의 인간 키나제(human kinases) 계통도(dendrogram)에 KD025-키나제(kinase) 상호 작용을 나타낸 도이다.
도 1d KD025에 의해 영향을 받는 키나제-리간드(kinase-ligand) 잔존 결합(binding) 활성의 가족 분포 패턴을 나타낸 도이다.
도 1e KD025의 키나제(kinase) 저해 활성(inhibitory effect)의 전체적인 분포를 히스토그램(histogram)으로 나타낸 도이다.
도 2는 해리 상수(dissociation constant, Kd)의 결정에 관한 도이다. 약물 (KD025, CX-4945 및 fasudil)과 키나제 (CK2 및 ROCK2) 간의 상호 작용은 KINOMEscanTM 프로파일링 플랫폼을 적용하여 측정되었다.
도 3은 CK2에 대한 KD025의 시험관 내(in vitro) 저해 효능(inhibitory efficacy)측정을 나타낸 도이다.
도 3a는 8 점 농도 (KD025의 경우 0, 0.1, 1, 3, 10, 30, 100 및 1000 nM; CX-4945의 경우 0, 0.001, 0.01, 0.03, 0.1, 0.3, 1 및 10 nM)에서 측정된 효소 활성을 나타낸 도이다.
도 3b는 KD025의 저해 효과(inhibitory effects)를 pan-ROCK 저해제(inhibitor)인 fasudil과 비교한 도이다.
도 4a는 Vero CCL-81 세포에서 KD025의 SARS-CoV-2 바이러스 활성 저해 효능 및 세포독성을 나타낸 도이다.
도 4b는 Vero CCL-81 세포에서 렘데시비르(Remdesivir)의 SARS-CoV-2 바이러스 활성 저해 효능 및 세포독성을 나타낸 도이다.
