Baloxavir or Baloxavir acid was developed by Shionogi and Co., Ltd as a selective inhibitor of the cap-dependent endonuclease (CEN) activity. CEN resides in the PA subunit of the influenza virus and mediates the critical "cap-snatching" step of viral RNA transcription. Thus Baloxavir can inhibit the influenza virus replication and now this drug is under investigation in clinical trial NCT04327791 (Combination Therapy With Baloxavir and Oseltamavir 1 for Hospitalized Patients With Influenza).

Route of Administration: Oral

In Vitro Use Guide

To assess the inhibitory effects of Baloxavir acid (BXA) on Cap-dependent endonuclease (CEN) and RNA-dependent RNA polymerase (RdRp) activities as well as the sequential reaction of CEN and RdRp (CEN/RdRp), recombinant 3Ptap derived from A/WSN/33 (H1N1) was subjected to a transcription assay. BXA inhibited CEN and CEN/RdRp activities with mean IC50 of 2.5 and 1.6 nM, respectively, while low potency (IC50 >40 nM) was observed against RdRp activity, suggesting that BXA selectively inhibits CEN activity.
