- the 6SL-PAMAM conjugate was prepared by reductive amination of the aldehyde group of the reducing sugar of 6SL with the amino group of the PAMAM dendrimer having ethylene diamine cores (G2 to G5) (FIG. 8).
- each PAMAM dendrimer (20 mg) was mixed with different amounts of 6SL solution (Table 1).
- Inhibition assays in vitro were performed using the ability assessment method of 6SL-PAMAM conjugates to inhibit influenza infection.
- a half-log serial dilution of the conjugate to be tested was prepared using PBS. 50 ⁇ l of the dilution prepared above was mixed with the same volume of 1 ⁇ 10 3 TCID50 H1N1 strain (A / California / 04/2009 or oseltamivir-resistant H1N1, A / Gyeongnam / 1820/2009). The mixture was incubated at 37 ° C. for 1 hour, and then 100 ⁇ l of 1.5 ⁇ 10 5 cells / ml of MDCK cells were added thereto, followed by further culture for 18 hours at 5% CO 2 and 37 ° C. conditions.
- FIG. 9 shows that as the number of 6SLs bound to the PAMAM conjugate increases, the inhibitory efficiency of the H1N1 virus decreases, which indicates that the binding affinity of the polyvalent ligand is dependent on the ligand valency (eg, the number of ligands). The increase was not consistent with the results of the previous studies.
- the surface area (4 ⁇ r 2 ) of the dendrimer is calculated using the diameter of the PAMAM dendrimer included in the 6SL-PAMAM conjugate, the surface area is divided by the number of 6SL ligands, and the spacing between 6SL ligands is calculated.
- the association between the ligand spacing and the inhibition of infection of the H1N1 virus was analyzed (Table 2, FIG. 10).
- NA neuraminidase
- the 6SL-PAMAM conjugate is preferably in a form containing an ethylene diamine core of G4 and G5, and preferably contains an appropriate level of 6SL ligand, depending on the type of the ethylene diamine core. It was found that the 6SL-PAMAM conjugate comprising 6 preferably contains about 20 to 30 6SL ligands, and the 6SL-PAMAM conjugate comprising G5 preferably contained about 30 to 6 6SL ligands.
- MDCK cells were seeded in 48 well plates and treated with or without S3-G4 (10 or 100 nmol / ml), various H1N1 viruses (A / NWS / 33, A / PuertoRico / 8/43 and A). / California / 07/2009) or H3N2 virus (A / Shandong / 9/93) were infected at 37 ° C. for 24 hours. The infected cells were treated with 4% paraformaldehyde and fixed at room temperature for 10 minutes, and then the fixed cells were washed with cold PBS and reacted for 10 minutes by adding PBS containing 0.25% Triton X-100. Again, washed three times with 5 minutes each with PBS.
- the washed cells were treated with influenza virus A NP-specific monoclonal antibody for 1 hour, and then reacted for 1 hour with the addition of Alexa 488-goat anti-mouse secondary antibody, photographed with a reversed-phase fluorescence microscope (FIG. 11). .
- the nuclei of the cells were counterstained using NucBLue fixed cell stain (Life technologies), and the actin of the cells was stained using ActinRed 555 ReadyProbes Reagent (Lifetechnologies).
- mice were anesthetized by intraperitoneal injection of Avertin (375 mg / kg), and intranasally administered S3-G4. After 10 minutes, 104EID50 (50% egg infective dose) of H1N1 virus (A / NWS / 33) was administered nasal. Infected. At this time, according to the administration level of S3-G4 and virus, it was classified into four test groups: positive control group (viral alone administration), negative control group (S3-G4 administration alone), comparison group (PBS administration alone) and experimental group (virus). And 50 ⁇ mol / kg S3-G4 administration. The mice of each test group were raised for 14 days, and then the experiments were performed.
- the negative control group (S3-G4 (50 ⁇ mol / kg)) and the control group (PBS) did not change the survival rate even after the breeding period
- the positive control group (H1N1) survival rate decreased from the 6th day It was confirmed that all started to die at the time 10 days passed.
- the survival rate was reduced to about 75% on day 8, but it was confirmed that the survival rate did not change thereafter.
- the negative control group (S3-G4 (50 ⁇ mol / kg)) and the control group (PBS) showed a tendency to gradually increase the weight as the breeding period, but both positive control group (H1N1) As the breeding period elapsed until 9 days immediately before death, it was confirmed that the weight decreased. On the contrary, in the experimental group (H1N1 + S3-G4), the weight was reduced by the breeding period up to 9 days, after which the weight was recovered as the breeding period was confirmed.
- Oseltamivir was performed in the same manner as in Example 2, except that oseltamivir resistant H1N1 virus (A / Gyeongnam / 1820/2009) was used as a virus and S3-G4 was used as the 6SL-PAMAM conjugate. Inhibition activity of S3-G4 against resistant H1N1 virus (A / Gyeongnam / 1820/2009) was analyzed (FIG. 16).
- H1N1 virus (A / Gyeongnam / 1820/2009) with or without S3-G4 was added to MDCK cells for 1 hour of infection, washed with PBS to remove unbound virus, and then various concentrations of oseltamivir Then, the cells were cultured in an agarose solid medium, superimposed the medium containing 1% agarose in the cultured solid medium, and then incubated for 48 hours at 37 °C. After the incubation was completed, the lower solid medium was stained with 1% crystal violet and plaques were counted (FIG. 17).
- the filter and the mask including the same may include a binder capable of directly binding to the HA protein present on the surface of the virus, and thus the virus may be filtered out of the filter before reaching the human body or an animal. have.
- the virus even if the virus passes through the filter to reach the human body or animal, it may not be able to penetrate into the somatic cells of the human body or animal due to the binding to the conjugate.
- it can be processed to attach a conjugate that can fundamentally block the infection of the virus, as well as objects that can be used by the public. Through this, it is possible to fundamentally prevent the transmission of respiratory diseases caused by the virus, there is an advantage that can prevent the pandemic caused by the virus in advance.
