Description: Pimodivir, also known as VX-787, JNJ-872, is a novel inhibitor of influenza virus replication that blocks the PB2 cap-snatching activity of the influenza viral polymerase complex. VX-787 binds the cap-binding domain of the PB2 subunit with a KD (dissociation constant) of 24 nM as determined by isothermal titration calorimetry (ITC). The cell-based EC50 (the concentration of compound that ensures 50% cell viability of an uninfected control) for VX-787 is 1.6 nM in a cytopathic effect (CPE) assay, with a similar EC50 in a viral RNA replication assay. VX-787 is active against a diverse panel of influenza A virus strains, including H1N1pdm09 and H5N1 strains, as well as strains with reduced susceptibility to neuraminidase inhibitors (NAIs).

More Info:

Biological target: Pimodivir (VX-787) is an orally bioavailable inhibitor of influenza A virus polymerases through interaction with the viral PB2 subunit.
In vitro activity: Pimodivir (VX-787) rescues macrophages from virus-mediated death at non-cytotoxic concentrations 24 hpi. The EC50 value for Pimodivir are 8 and 12 nM for A(H1N1) and A(H3N2) strains, respectively, whereas the CC50 values are >1 μM, giving selectivity indexes (SI) > 125 and > 83 for A(H1N1) and A(H3N2) strains, respectively. Pimodivir significantly attenuates the transcription of viral M1 RNA in macrophages, which are infected with A(H1N1) or A(H3N2) strains for 8 h. Pimodivir inhibits the transcription of viral but not cellular genes. Pimodivir allows some activation of IAV-mediated expression of several cellular genes, which are involved in tryptophan and nucleotide metabolism. Pimodivir possesses excellent anti-IAV but not immuno/metabolo-modulating effect.

In vivo activity: VX-787 shows consistent activity against the H1N1pdm09 strain and a highly pathogenic avian influenza virus A/Viet Nam/1203/2004 strain. PB2 has been reported to play a significant role in host restriction (57, 58), with a K627E substitution observed in avian strains relative to human-derived strains. VX-787 is equally effective against strains containing this K627E variant, which is outside the PB2 cap-binding site (data not shown). Targeting PB2 instead of neuraminidase in the influenza virus replication cycle provides several unique opportunities. At any point during the course of disease in vivo, there are both infected cells that need to be controlled and as-yet-uninfected cells that need to be protected; VX-787 has the potential to perform both functions. The means by which VX-787 blocks CPE in infected cells could simply be inhibition of (+)-strand viral RNA synthesis, but it is possible that other mechanisms, such as interference with influenza virus-induced host cell shutoff, are involved (59, 60). Many details of the function of PB2 remain to be elucidated. The effect of VX-787 on lung viral loads in mice is positive. At several different doses, VX-787 showed a 1 to >5 log viral load reduction relative to vehicle controls. Administration of VX-787 provides a rapid reduction in the amount of influenza A virus in the lungs of infected mice and suggests a direct effect on viral replication. This result is consistent with the observed MOI independence of VX-787; initially infected lung cells may create a local high-MOI environment that would remain under antiviral suppression by VX-787 but not be suppressed by oseltamivir. The results from this series of studies represent the first evidence that a pharmacologic inhibitor of influenza A virus PB2 effectively inhibits viral replication in vivo and successfully abrogates or attenuates influenza virus infection in mouse models of the disease.
