A series of 1,2,4-triazole-3-sulfide derivatives were designed and synthesized. Their chemical structures were confirmed by 1H NMR, 13C NMR, MS and elemental analysis. The crystal structure of (E)-4-(4-hydroxy-3-methoxyphenyl-methyleneamino)-5-ethyl-4H-1,2,4-triazole-3-propylsulfide (1c) was determined by X-ray diffraction analysis. The preliminary assay of neuraminidase (NA, H1N1) inhibitory activity in vitro showed that most of compound 1 has more potent NA inhibitory activity. Among them, compounds (E)-4-(4-hydroxy-3-methoxyphenyl-methyleneamino)-5-ethyl-4H-1,2,4-triazole-3-ethylsulfide (1b) and 1c showed the best inhibitory activity with IC50 values of (6.86±2.08) and (9.1±1.56) μg/mL, respectively.
