| In vitro | Cinanserin and Cinanserin hydrochloride inhibit the catalytic activity of SARS-CoV 3CLpro and HCoV-229E 3CLpro (IC50: 4.68 μM and 5.68 μM). Cinanserin/Cinanserin hydrochloride has a binding affinity to SARS-CoV 3CLpro, HCoV-229E 3CLpro, with the KD values of 49.4 μM/78.0 μM for SARS-associated coronavirus (SARS-CoV) 3CLpro[1]. |
| In vivo | Cinanserin (5 mg/kg; intravenous injection; 2 hours; male Wistar rats) treatment significantly reduces systemic burn edema to shamburn levels[2]. |
