Abstract

In this work, a series of newly-synthesized amide derivatives (A1~A26) carrying 1,3,4-thiadiazole and pyrazole moieties were successfully designed and synthesized. In addition, their structures were characterized by multiple techniques including ¹H NMR, ¹³C NMR, IR, ESI-MS and HRMS. Furthermore, based on the antitumor results against human hepatocarcinoma cells (HepG2) and human gastric carcinoma cells (MGC803) via methyl thiazolyl tetrazolium (MTT) method, the in vitro cytotoxic activities of the compounds were evaluated, indicating that compounds A1 (IC₅₀=0.0695 μmol/mL), A2 (IC₅₀=0.0682 μmol/mL) and A3 (IC₅₀=0.0753 μmol/mL) exhibited similar inhibitory effect against HepG2 cells. More importantly, compound A1 displayed superior inhibition performance against MGC803 cells (IC₅₀=0.0420 μmol/mL) compared with that of 5-fluorouracil (IC₅₀=0.0820 μmol/mL).

Key words: amide derivatives, organic synthesis, 1,3,4-thiadiazole, pyrazole, antitumor activity
