: In this work, 1,2,4-triazine derivatives were synthesized and evaluated for anticancer activities. Series of 1,2,4-triazine derivatives (4a, b) were prepared via the reaction of N-benzoyl glycine (1) with aromatic aldehydes in presence of fused sodium acetate and acetic anhydride to give 1,3-oxazolinone derivatives (2a, b), followed by condensation with 1-(ethoxycarbonyl) hydrazine (3) in glacial acetic acid. Compounds (4a, b) then reacted with acetic anhydride, ethyl chloroacetate and 2,4-dinitrophenyl hydrazine yielded the corresponding to N-acetyl derivatives (5a, b), N-(ethoxycarbonyl) methyl derivative (6) and 1,2-disubstituted hydrazine (7), respectively. The structures of the 1,2,4-triazine derivatives were confirmed by IR, 1H, 13C NMR, MS and elemental analyses. Anticancer activity of some 1,2,4-triazine derivatives (4-7) have been investigated. The results revealed that compounds 4a (IC50= 2.7μM), 5a (IC50= 1.5μM), and 5b (IC50= 3.9μM) show promising inhibitory growth efficacy compared to a standard antitumor drug (IC50= 4.6μM). These three compounds can be considered as potential agents against human hepatocellular carcinoma cell lines (HepG-2).
