CL385319 is a potent inhibitor of H5N1 avian influenza A virus. CL-385319 inhibits H5N1 avian influenza A virus infection by blocking viral entry. CL-385319 is effective in inhibiting infection of highly pathogenic H5N1 influenza A virus in Madin-Darby Canine Kidney (MDCK) cells with an IC50 of 27.03±2.54 μM. CL385319 with low cytotoxicity (CC50=1.48±0.01 mM) could also inhibit entry of pseudoviruses carrying hemagglutinins from H5N1 strains that were isolated from different places at different times, while it had no inhibitory activity on the entry of VSV-G pseudotyped particles. | [Uses]
CL-385319 is an N-substituted piperidine compound with inhibitory activity against H5N1 avian influenza A virus infection. CL-385319 exhibited an IC50 of 27.03±2.54 μM against infection of highly pathogenic H5N1 virus in Madin-Darby canine kidney cells (MDCK). CL-385319 had low cytotoxicity with a CC50 of 1.48 mM and was able to inhibit the entry of pseudoviruses carrying H5N1 strains from different sources, but had no inhibitory effect on the entry of VSV-G pseudotyped particles. Pseudoviruses with the M24A mutation in HA1 or the F110S mutation in HA2 were resistant to CL-385319, indicating that these two residues in the cavity region may be critical for the binding of CL-385319[1]. | [References]
