ABSTRACT
A series of new fluoroquinazolinone 6â»8 and 10aâ»g derivatives was designed, prepared and screened for their in vitro cytotoxic activity against human cancer cell lines MCF-7 and MDA-MBA-231. Compounds 6 (IC50 = 0.35 ± 0.01 µM), 10f (IC50 = 0.71 ± 0.01 µM), 10d (IC50 = 0.89 ± 0.02 µM) and 10a (IC50 = 0.95 ± 0.01 µM) displayed broad spectrum anticancer activity better than the reference drug gefitinib (IC50 = 0.97 ± 0.02 µM) against MCF-7. Compounds 10e (IC50 = 0.28 ± 0.02 µM), 10d (IC50 = 0.38 ± 0.01 µM), 7 (IC50 = 0.94 ± 0.07 µM) and 10c (IC50 = 1.09 ± 0.01 µM) showed better activity than the reference gefitinib (IC50 = 1.30 ± 0.04 µM) against MDA-MBA-231. Moreover, EGFR and tubulin inhibition assays were performed for the highest active derivatives and showed remarkable results comparing to the reference drugs. In order to assess and explain their binding affinities, molecular docking simulation was studied against EGFR and tubulin binding sites. The results obtained from molecular docking study and those obtained from cytotoxic screening were correlated.
