Surflex-Dock is employed to investigate interactions between neuraminidase inhibitors (NIs) and neuraminidase (NA), which illuminate that carboxyl group, amino (guanidino) group, amide group, hydroxy group are crucial. Hydrogen bonds and hydrophobic interactions impact on activities of NIs. There is a strong correlation between binding affinity and pIC(50), with r=0.813. We have developed three-dimensional holographic vector of atomic interaction field analysis (HoVAIFA) as a new method of 3D-QSAR to understand chemical-biological interactions. Good results, R(2) = 0.789 and R(2)cV = 0.732, show that HoVAIFA can be applicable to molecular structural characterization and bioactivity prediction. Electrostatic, steric and hydrophobic interactions affect activities of NIs. HoVAIFA and docking results are corresponding, which illustrates that HoVAIFA is an effective methodology for characterization of complex interactions of drug molecules.
