In mice models infected with A/WSN/33, PAN endonuclease-IN-3 significantly suppresses viral replication. |
| In vitro | PAN endonuclease-IN-3 (Compound 39-(S)) exhibits IAV polymerase inhibitory activity in HEK-293T cells with an IC₅₀ value of 17.4 nM, comparable to Baloxavir (IC₅₀ = 17.8 nM). PAN endonuclease-IN-3 (1-103 nM) strongly inhibits PAN endonuclease with an IC₅₀ of 41.8 nM. Additionally, in the MDCK cell line, PAN endonuclease-IN-3 (46 μL/well, 72 h) demonstrates exceptional antiviral activity with an EC₅₀ of 0.21 nM. |
| In vivo | PAN endonuclease-IN-3 (20 mg/kg, Intranasal administration, single dose) suppresses viral replication of the A/WSN/33 virus in the lungs of infected mice. |
| Storage | Powder: -20°C for 3 years | In solvent: -80°C for 1 year | Shipping with blue ice/Shipping at ambient temperature. |
