Neuraminidase (NA) plays an important role in replication and the release of a new avian influenza virion. In consequence, NA has been considered as a valid target in drug design against influenza virus. The aim of this study was to identify the new neuraminidase inhibitors using molecular docking simulation based on virtual screening from natural products compounds. The X-ray crystal structure of neuraminidase type N1 (PDB id: 3B7E) and N1 mutant (PDB id: 3NNS) using Autodock 4.2 program. Zanamivir was used as the control ligand and docked against neuraminidase type N1, further plotted between log IC50 value experiments of sialic acid derivatives compound versus log of Ki value of molecular docking. Molecular docking simulation was performed on 113 herb compounds along with zanamivir and oseltamivir as the control ligands. The result showed that the best interaction against of neuraminidase N1 and N1 mutant from herbs compound is katsumadain-A withfree energy value -7,54 kcal/mol and -7,46 kkal/mol, respectively. Katsumadain-Aformed hydrogen bond with amino acid residue Arg118 and Arg371 on neuraminidase and neuraminidase N1 mutant Katsumadain-A was also connected with Arg118 through hydrogen binding interaction. This in silico results also was proved by in vitro MUNANA assay.
