A series of aroylquinoline derivatives were synthesized and evaluated for anticancer activity. 5-Amino6-methoxy-2-aroylquinoline 15 showed more potent antiproliferative activity (IC50 values ranging from 0.2 to 0.4 nM) as compared to la (combretastatin A-4) (IC50 = 1-9-835 nM) against various human cancer cell lines and a MDR-resistant cancer cell line. Compound 15 (IC50 = 1-6 μM) exhibited more potent inhibition of tubulin polymerization than la (IC50 = 2.1 μM) and showed strong binding property to the colchicine binding site of microtubules.
