[h=3]Abstract[/h] Neuraminidase (NA) is one of the particular potential targets for novel antiviral therapy. In this work, a series of neuraminidase inhibitors with the cyclohexene scaffold were studied based upon the combination of 3D-QSAR, molecular docking, and molecular dynamics techniques. The results indicate that the built 3D-QSAR models yield reliable statistical information: the correlation coefficient (r[SUP]2[/SUP]) and cross-validation coefficient (q[SUP]2[/SUP]) of CoMFA (comparative molecular field analysis) are 0.992 and 0.819; the r[SUP]2[/SUP] and q[SUP]2[/SUP] of CoMSIA (comparative molecular similarity analysis) are 0.992 and 0.863, respectively. Molecular docking and MD simulations were conducted to confirm the detailed binding mode of enzyme-inhibitor system. The new NA inhibitors had been designed, synthesized, and their inhibitory activities against group-1 neuraminidase were determined. One agent displayed excellent neuraminidase inhibition, with IC[SUB]50[/SUB] value of 39.6 μM against NA, while IC[SUB]50[/SUB] value for oseltamivir is 61.1 μM. This compound may be further investigated for the treatment of infection by the new type influenza virus.
