A series of 4-(substituted-3-phenylideneamino)-3-(3,4,5-trimethoxyphenyl)- 1H-1,2,4-triazole-5(4H)-thione 3 were synthesized by condensation reaction of 4-amino-3-(3,4,5-trimethoxyphenyl)-1H-1,2,4-triazole-5(4H)-thione (2) with various substituted benzaldehydes. Alkylation of 3 with alkyl halides afforded [1,2,4]triazolo- [3,4-b][1,3,4]thiadiazine derivatives 4. Their structures were confirmed by 1H NMR, 13C NMR, IR and elemental analyses. Preliminary bioassay indicated that some compounds posed antitumor activity to PC3 cells in vitro by MTT method. The antiproliferation activity of compound 4a to PC3 cells at the concentration of 10 μmol?L-1 was 75.9 %.
