Abstract:


Aims: Tyrosine kinases and topoisomerase I are common target enzymes for the majority of the anticancer agents. In contrast to quinazolines and quinolines, kinase inhibitors and topoisomerase inhibitors incorporating cinnoline scaffold are relatively infrequent. Thus the aim of this work was to replace the former scaffolds with the latter one. Eighteen novel cinnoline derivatives were designed, synthesized and characterized using both microanalytical and spectral data.

Methods: The cytotoxic activity of the new compounds was screened in vitro against both human breast cancer cells and normal breast cells.

Results: The enzymatic inhibition activity of promising candidates against both epidermal growth factor receptor tyrosine kinase and topoisomerase I was accomplished.

Conclusions: Cell cycle profiles were observed at IC50 doses of representative biologically active compounds. Compound 7 represented a new scaffold incorporating triazepinocinnoline ring system and showed outstanding cytotoxic activity against MCF-7 (0.049 μM), tyrosine kinase inhibition (0.22 μM), apoptosis percentage and the highest selectivity index.

Keywords:

Topoisomerase I inhibitors, epidermal growth factor receptor tyrosine kinase inhibitors, 4-aminocinnoline-3-carboxylic acid hydrazide, cell cycle arrest, triazepinocinnolines, immunofluorescence.
