R-1479 is a specific inhibitor of HCV replication in the HCV subgenomic replicon system (IC50=1.28 μM).

IC50 & Target

IC50: 1.28 μM (HCV replication)[1]

In Vitro

R-1479 (R1479) inhibits HCV RNA replication with a mean IC50 value of 1.28 μM when measured as dose-dependent reduction of Renillaluciferase activity after a 72 h incubation of proliferating replicon cells. R-1479 shows no effect on cell viability or proliferation of HCV replicon or Huh-7 cells at concentrations up to 2 mM[1]. The most potent and non-cytotoxic derivative is R-1479 with an IC50 of 1.28 μM in the HCV replicon system. The triphosphate of R-1479 is prepared and shown to be an inhibitor of RNA synthesis mediated by NS5B (IC50=320 nM), the RNA polymerase encoded by HCV. R-1479 displays good activity in the replicon assay with no measurable cytotoxic or cytostatic effect[2].

Kinase Assay

The membrane-associated, native HCV replicase complex is isolated from 2209-23 HCV replicon cells and a derived cell line carrying HCV replicon RNA with a S282T mutation in the NS5B coding sequence. The in vitro replicase assay contain 10 μL of cytoplasmic membrane fraction, 50 mM HEPES (pH 7.5), 10 mM KCl, 10 mM dithiothreitol, 5 mM MgCl2, 20 μg/mL actinomycin D, 1 mM ATP, 1 mM GTP, 1 mM UTP, 30 μCi of [α-33P]CTP (3000 Ci/mmol, 10 mCi/mL), 1 unit/μL SUPERase•In, 10 mM creatine phosphate, and 200 μg/mL creatine phosphokinase in a final volume of 25 μL. Inhibition by nucleotide analogs is determined[1].

Cell Assay

R-1479 is dissolved in DMSO and stored, and then diluted with appropriate media before use[1].

The effect of R-1479 on the incorporation of tritiated thymidine into cellular DNA is measured using the [3H]thymidine incorporation scintillation proximity assay system. MTT and WST-1 assay systems are used to measure cell viability. The ATP bioluminescence assay kit HSII is used to measure intracellular ATP levels[1].
