MBX2546 is a non-cytotoxic (CC50 >100 μM; 283T) molecule that inhibits against influenza hemagglutinin- (HA-) mediated viral entry (IC90 = 5.7 μM against HIV/HA(H5) entry in 293T culture vs. IC90 >100 μM, 98.2 μM, and >85 μM against HIV/LASV-GP, HIV/EBOV-GP, HIV/VSV-G, respectively) by targeting group 1 HA-specific conformational epitope in the HA stem loop region. MBX2546 is shown to inhibit influenza A strains A/PR/8/34 (H1N1) and A/Florida/21/2008 (H1N1-H275Ψ) (oseltamivir-resistant strain), A/California/10/2009/H1N1, as well as high pathogenic avian influenza (HPAI) strain A/Hong Kong/H5N1 (IC50 = 0.3, 5.8, 0.55-1.5, and 3.6 μM, respectively), but not A/Texas/12/2007 (H3N2), A/Perth/16/2009 (H3N2), A/Victoria/3/75 (H3N2), A/Panama/2007/99 (H3N2), A/Sydney/05/97 (H3N2), A/California/7/04 (H3N2), A/Wyoming/03/2003 (H3N2), or influenza B strain B/Florida/4/2006 in MDCK cultures.
Non-cytotoxic molecule that blocks hemagglutinin (HA)-mediated influenza A host entry by targeting group 1 HA stem loop region conformational epitope.

An ultrahigh-throughput screen was performed to identify novel small molecule inhibitors of influenza virus replication. The screen employed a recombinant influenza A/WSN/33 virus expressing Renilla luciferase and yielded a hit rate of 0.5%, of which the vast majority showed little

Influenza A virus envelop protein hemagglutinin (HA) plays important roles in viral entry. We previously have reported that MBX2546, a novel influenza A virus inhibitor, binds to HA and inhibits HA-mediated membrane fusion. In this report, we show that (i)

Influenza viruses are a major public health threat worldwide, and options for antiviral therapy are limited by the emergence of drug-resistant virus strains. The influenza virus glycoprotein hemagglutinin (HA) plays critical roles in the early stage of virus infection, including
