摘      要：A series of novel 3-（（4-（t-buty-）-2-（2-benzylidenehydrazinyl）thiazol-5-yl）methyl）quinolin-2（1H）-ones （7a--7z） were designed, synthesized and evaluated for their ability of inhibiting neuraminidase （NA） of influenza H1N1 virus. Some compounds displayed moderate influenza NA inhibitory activity. Compound 71 with the scaffold of 2-（2-（2-methoxybenzylidene）hydrazinyl）thiazole was the best one, exhibiting moderate NA inhibitory activity with ICs0 of 44.66 ~tmol/L. Structure-activity relationship showed that compounds with methoxy or hydroxy groups at the ortho position, fluorine and nitro groups at the meta position and chlorine and bromine groups at the para posi- tion of phenyl ring were more active. Docking study indicated that compound 71 has important interactions with some key residues （including Asp151, Glu119, Arg292, Tyr406, and Asn347） and binds to 430-cavity adjacent to NA active site.
