Abstract

N-Arylindazole-3-carboxamide derivatives synthesized from an anti-MERS-CoV hit compound showed potent inhibitory activities against SARS-CoV-2. Among them, 5-chloro-N-(3,5-dichlorophenyl)-1H-indazole-3-carboxamide (4a) exhibited a potent inhibitory effect (EC50 = 0.69 µM), low cytotoxicity, and satisfactory in vitro PK profiles. Thus, N-arylindazole-3-carboxamide 4a provides a novel template for future development of anti-coronavirus agents.
