The non‐immunosuppressive cyclosporin DEBIO‐025 is a potent inhibitor of hepatitis C virus replication in vitro
Jan Paeshuyse, Artur Kaul, Erik De Clercq, Brigitte Rosenwirth, Jean‐Maurice Dumont, Pietro Scalfaro, Ralf Bartenschlager, Johan Neyts – 23 March 2006 – Cyclosporin A (CsA) inhibits the in vitro replication of HCV subgenomic replicons. We here report on the potent anti‐HCV activity of the non‐immunosuppressive cyclosporin DEBIO‐025. The 50% effective concentration for inhibition of HCV subgenomic replicon replication in Huh 5‐2 cells (luciferase assay) by DEBIO‐025 was 0.27 ± 0.03 μg/mL and for CsA 2.8 ± 0.4 μg/mL.
