Biological Activity

JNJ4796 (JNJ-4796) is a potent, orally bioavailable small molecule fusion inhibitor of influenza virus, selectively binds to Group-1 subtype of influenza A viruses HA.

JNJ4796 dose-dependently prevents pH-induced transition of HA to the post-fusion conformation and subsequent loss of the HA1 subunit after reduction of the inter-chain HA disulfide.

JNJ4796 stabilizes the pre-fusion conformation and blocks the HA conformational change at low pH and the subsequent susceptibility to trypsin.

JNJ4796 binds with a stoichiometry of three binding sites per trimer in a highly conserved hydrophobic groove at the HA1/HA2 interface in the HA stem.

JNJ4796 demonstrated high potency (EC50=12-66 nM) of virus neutralization against representative influenza viruses: Influenza A H1N1 (H1/Bris), H1N1 A/California/07/2009 (H1/Cal), H1N1 A/New Caledonia/20/1999 (H1/NCa), H1N1 A/Puerto Rico/8/1934 (H1/PR8), H1N1 A/Solomon Islands/3/2006 IVR-145 (H1/SI06), weaker effect against H5N1 A/Hong Kong/156/1997 (H5/H97, EC50=449 nM), H5N1 A/Vietnam/1194/2004 (H5/Viet, EC50=3240 nM), and no potency against H3N1 A/Brisbane/10/2007 (H3/Bris), H7 NY (7:1 reassortant virus with the HA of A/New York/107/2003 (H7N7).
