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
The present invention relates to compounds of the formula
medicaments containing them and the use of these compounds as pharmaceutically active agents. The compounds exhibit activity as Raf kinase inhibitors and therefore may be useful for the treatment of diseases mediated by said kinases, especially as anticancer agents.

Based on the hybrid pharmacophore design concept, a novel series of dual diaryl urea and N-acylhydrazone derivatives were synthesized and evaluated for their in vitro cytotoxicity by the standard MTT assay. The pharmacological results indicated that most compounds exhibited moderate to excellent activity. Moreover, compound 2g showed the most potent cytotoxicity against HL-60, A549 and MDA-MB-231 cell lines, with IC50 values of 0.22, 0.34 and 0.41 μM, respectively, which was 3.8 to 22.5 times more active than the reference compounds sorafenib and PAC-1. The promising compound 2g thus emerges as a lead for further structural modifications.

of semicarbazone derivativesbearing phenyl moiety were synthesized and evaluated for the vitro anticanceractivities in four human cancer cell lines (human colon cancer (HT29), human neuro-blastoma (SK-N-SH), human breast cancer (MDA-MB-231), and human gastric cancer (MKN45)). Biological evaluation led to the identification of 11q and 11s, which showed excellent anticanceractivities against tested
