Özet

In the present investigation, the key intermediate acetohydrazide derivative 5 was synthesized starting from 3-(4-methoxybenzyl)-4-amino-4,5-dihydro-1,2,4-triazol-5-one (1) by a four-step reaction. Thiosemicarbazides 6a-f and arylidenehydrazide derivatives 8a-d were obtained from compound 5. The cyclization of compounds 6a-f in the presence of NaOH resulted in the formation of compounds 7a-f. The compounds were characterized by IR, H-1 NMR, C-13 NMR spectroscopy, elemental analysis and mass spectial studies. The compounds were tested for their anti-lipase, anti-alpha-glucosidase and anti-mycobacterial activities. Compounds 6b and 8c exhibited excellent anti-lipase activity, and compound 8d showed excellent anti-alpha-glucosidase activity. Compounds 3 and 4 exhibited good anti-tuberculosis activity.
