A protease inhibitor.
General information
is a dipeptide-type SARS-CoV 3CL protease inhibitor with anti-SARS-CoV activity in vitro (IC50 <1 μM) (Thanigaimalai et al., 2013). It was shown to form a reversible covalent bond and further polar interactions with the SARS-CoV-2 3C-like protease in vitro, which leads to potent inhibition of the enzyme (EC50 of ca. 4.2 μM). It might act synergistically with remdesivir (Hattori et al., 2021).

The compound’s EC50 value for Vero E6 cells was ca 4.2 μM. It acted synergistically with remdesivir. Based on results acquired using crystallization, mass spectrometry and fluorimetry techniques, it was suggested to form a reversible covalent bond with 3CLpro. |
