Description:

WARNING: This product is for research use only, not for human or veterinary use.

Nucleozin is an antivirus agent. Nucleozin targets influenza A nucleoprotein (NP), a multifunctional, RNA-binding protein necessary for virus replication. Nucleozin is effective in fighting H1N1, H3N2, and H5N1 flu virus strains by inducing the formation of NP aggregates and antagonizing its nuclear accumulation, leading to cessation of viral replication.

Biological target:
Nucleozin, a potent inhibitor of influenza A virus infection, induces the formation of nucleoprotein (NP) aggregates and antagonizes its nuclear accumulation, leading to cessation of viral replication.
In vitro activity:
To test if nucleozin blocked onward transport from the RE, images of living virus-infected cells containing GFP-NP-tagged RNPs, as well as RFP-Rab11 were acquired. A549 cells were transfected with GFP-NP and RFP-Rab11, infected with PR8 virus or mock infected 12 h later, and imaged at 8 hpi. The effect of adding nucleozin was then tested. In mock-infected cells, drug addition had little apparent effect, in terms of both the overall localization patterns of GFP-NP and RFP-Rab11 (Fig. 4A) and their movement in time-lapse movies (see min 4.5 to 29 of Movie S1). However, when the drug was added to infected cells, the result was a dramatic loss of the small, highly mobile GFP-NP- and RFP-Rab11-positive bodies, which were replaced by increasingly large cytoplasmic aggregates that still contained both proteins but that in many cases collapsed back onto the perinuclear region (Fig. 4C; see Movie S3). High-magnification movies of vRNP-decorated vesicles moving in the cytoplasm of infected cells showed that they were highly mobile and that while there were apparently continual interactions among them, these were transient (see Fig. S3A [white arrowheads] and Movie S4 in the supplemental material). However, in the presence of nucleozin, interacting vesicular structures tended to remain attached over time, thus forming large agglomerations. (see Fig. S3B [white arrowheads] and Movie S5). Thus, nucleozin exerts a general block to cytoplasmic transport of RNP-Rab11 complexes by sticking vRNPs and their associated transport machinery together, most likely via NP-NP interactions.
