title: Synthesis and antiproliferative evaluation of 4-anilino-n-methoxyfuro[2,3-b]quinoline derivatives (n=6, 7). Part 5.
abstract: A series of 27 differently substituted 4-anilinofuro[2,3-b]quinolines were synthesized and evaluated for their antiproliferative activities against the HeLa, SKHep1, SAS, AGS, A549, and CE81T cell lines, cancers commonly found in Asian countries. Among the compounds tested, 1-{4-[(3-chloro-7-methoxyfuro[2,3-b]quinolin-4-yl)amino]phenyl}ethanone (1) was the most potent, with IC(50) values of 3.1, 3.0, and 4.2 microM, resp., against the growth of HeLa, SKHep, and CE81T cells. Compound 1 was, thus, further evaluated by flow cytometry to evaluate its effect on the cell-cycle distribution of HeLa cells. Our results indicated that 1 readily induces cell-cycle arrest in the G2/M phase, followed by DNA fragmentation and, ultimately, cell death.
