Synthesis and cytotoxicity studies of novel 2-hydrazonylpyrido[2,3-b] pyrazin-3(4H)-ones

In an attempt to develop potent antitumor agents, a series of novel 2-hydrazonylpyrido[2,3-b]pyrazin-3(4H)-one derivatives were designed and synthesized. All the prepared compounds were screened for their cytotoxic activities against A549, MDA-MB-231 and HT-29 cell lines in vitro. Pharmacological data indicated that five of the target compounds showed cytotoxicity against A549 cell line below a concentration of 1 μM. Compound 15g was the most potent one with IC50 values of 0.19, 2.11 and 2.15 μM against A549, MDA-MB-231 and HT29 cell lines, respectively. A series of 2-hydrazonylpyrido[2,3-b]pyrazin-3(4H)-one derivatives was designed and synthesized. Preliminary structure-activity relationships suggested that compounds with 4-methoxyphenyl or 4-(trifluoromethoxy)phenyl groups on the N-4 position were generally more potent than those with an unsubstituted phenyl group.
