Simeprevir Chemical Structure CAS:923604-59-5
Simeprevir is a potent HCV NS3/4A protease inhibitor, and inhibits HCV replication with EC50 of 8 nM.
In Huh7-Luc cells, antiviral activity of simeprevir (TMC435350) is dose dependent, and the EC50 and EC90 values determined for TMC435350 are 8 nM and 24 nM, respectively. Inhibition of TMC435350 on NS3/4A protease is time dependent, and the overall Kis are estimated to be 0.5 nM for genotype 1a and 0.4 nM for genotype 1b, respectively. TMC435350 is a potent inhibitor of HCV NS3/4A protease (Ki=0.36 nM) and viral replication (replicon EC50=7.8 nM).
In rats, TMC435350 (40 mg/kg, p.o.) is extensively distributed to the liver and intestinal tract (tissue/plasma area under the concentration-time curve ratios of >35), and the absolute bioavailability is 44%.
In vitro inhibition of NS3/4A activity is determined using a fluorescence resonance energy transfer cleavage assay with the RetS1 peptide substrate, derived from the genotype 1a NS4A-4B junction, and bacterially expressed full-length NS3 protease domain, supplemented with an NS4A peptide. Briefly, NS3/4A is preincubated in the presence of TMC435350 for 10 min, and then the RetS1 substrate is added and fluorescence is continuously measured for 20 min (excitation, 355 nm; emission, 500 nm). Cleavage of the substrate is expressed as a percentage of the cleavage seen with the vehicle control.
Huh7-Luc cells are seeded at a density of 2,500 cells/well in a 384-well plate in Dulbecco's modified Eagle's medium plus 10% fetal calf serum and incubated with a range of concentrations of serially diluted simeprevir, in a final DMSO concentration of 0.5% in the absence of G418. After 72 h of incubation, Steady Lite reagent is added in a 1:1 ratio to the medium, and luciferase signal is measured using a ViewLux reader.
Twenty-four male specific-pathogen-free Sprague-Dawley rats, weighing between 200 and 300 g at the time of dosing, are divided into eight groups of three rats each. Seven groups are dosed orally (p.o.) by gastric intubation of a vitamin E acetate-d-α-tocopheryl polyethylene glycol 1000 succinate-polyethylene glycol 400 solution of Simeprevir (TMC435350) at 2 mL/kg body weight to provide a dose of 40 mg/kg. One group is dosed intravenously (i.v.) by slow bolus injection in a tail vein of a 20% 2-hydroxypropyl-β-cyclodextrin formulation of TMC435350 (containing TMC435350, 100 mg/mL 2-hydroxypropyl-β-cyclodextrin, 0.1 N NaOH to pH 8.0±0.1, and mannitol-and pyrogen-free water) at 2 mL/kg body weight to provide a dose of 4 mg/kg. Water and food are available ad libitum during the study.
