MBX2329, a potent influenza virus inhibitor, specifically inhibits hemagglutinin (HA)-mediated viral entry with HIV/HA(H5) displaying IC90 of 8.6 μM. MBX2329 inhibits a wide spectrum of influenza A viruses, which includes the 2009 pandemic influenza virus A/H1N1/2009, highly pathogenic avian influenza (HPAI) virus A/H5N1, and oseltamivir-resistant A/H1N1 strains[1].
