Simeprevir (TMC435; TMC435350) sodium is an oral, potent and highly specific hepatitis C virus (HCV) NS3/4A protease inhibitor with a Ki of 0.36 nM. Simeprevir sodium inhibits HCV replication with an EC50 of 7.8 nM. Simeprevir sodium also potently suppresses SARS-CoV-2 replication and synergizes with Remdesivir. Simeprevir sodium inhibits the main protease (Mpro) and the RNA-dependent RNA polymerase (RdRp) of SARS-CoV-2, and also modulates host immune responses[1][4].

Target	Ki: 0.36 nM (HCV NS3/4A protease)[1] EC50: 7.8 nM (HCV replication)[1] IC50: 9.6±2.3 μM (SARS-CoV-2 Mpro), 5.5±0.2 μM (SARS-CoV-2 RdRp)[4]
In Vitro	Simeprevir (TMC435) inhibits HCV in a dose-dependent manner in Huh7-Luc cells, with EC50 and EC90 values of 8 nM and 24 nM, respectively[2]. Simeprevir (TMC435) inhibits NS3/4A proteases from HCV genotypes 1 to 6 with IC50s of 1/0.9/7/30/1.5/2.2/1.6 nM for 1a/1b/2b/3a/4/5/6, respectively[3]. Simeprevir inhibits SARS-CoV-2 in Vero E6 cells with an IC50 of 9.6±2.3 μM and 5.5±0.2 μM for Mpro and RdRp, respectively[4].
In Vivo	Simeprevir (TMC435) has moderate terminal elimination half-life (t1/2=1.5 h and 4.1 h for rat (3 mg/kg, p.o.), monkey (3 mg/kg, p.o.))[3]. Simeprevir (TMC435350) exhibits a medium-slow rate of absorption, well distribution with the high concentration observed in the liver, and a low clearance[1].
