RSV

The 5′-triphosphate form of ALS-8112 (ALS-8112-TP) is the active form of the drug and selectively inhibits RSV polymerase through chain termination of RNA synthesis. ALS-008112 enters various types of epithelial cells in the respiratory tract and is subsequently phosphorylated to form an intracellular nucleoside triphosphate with a half-life of approximately 29 hours. The nucleoside triphosphate analogue inhibits RSV replication by means of chain termination. ALS-8112 is a pan-strain inhibitor of RSV replication in vitro. The RNA transcription activity of the RSV–RNP complex is dose-proportionally inhibited by ALS-8112-TP with an IC50 of 0.020 ± 0.008 μM.
