A novel quinolinyl pyrrolone and quinolinyl pyridazinone derivatives has been synthesized and characterized using different spectroscopic and elemental analysis techniques. Most of the target compounds displayed promising antiproliferative activity; In general, the pyrrolone derivatives 4a-f exhibited higher antiproliferative activity than their corresponding pyridazinone. The pyrrolone 4f showed outstanding antiproliferative activity with moderate selectivity against CNS and renal cancer with selectivity ... Read more
