In this study, we designed and synthesized sixteen new derivatives of 7-amino-4-methylquinolin-2(1H)-one with potential anticancer activity. The structures of synthesized compounds were confirmed by 1H and 13 C NMR. The activity of novel substances was evaluated by cell viability assay and wound healing assay. In vitro tests for series of sixteen novel compounds were performed. The results showed that examined compounds are selective for a cancer cells, but their activity for various types of cancer is different. Three of the new compounds presented the ability to inhibit cells migration. The novel compounds constitute a good starting point for further studies and optimization of structure for new therapeutically effective anti-cancerous drugs. Seven compounds, which showed the highest rate of cell inhibition, were selected for further studies.
