| Summary: | This study investigated the antiproliferative activity of three classes of benzo[<i>f</i>]pyrrolo[1,2-<i>a</i>]quinoline azatetracyclic derivatives. All compounds were screened against 60 cancer cell lines at a single dose of 10 μM. When we compared the activity of the three classes of azatetracyclic derivatives (azide, monobrominated and dibrominated), we found that the dibrominated compounds were less active, while the azides were the most active molecules. Compounds <b>3b</b> and <b>5a</b>, showing the best growth inhibition profile of all the drugs evaluated, were selected for the second stage of a full five-dose testing. According to the results of the in vitro screening, compounds <b>3b</b> and <b>5a</b> exhibit good to moderate anticancer activity (in micromolar range) against all nine cancer sub-panels, with compound <b>5a</b> being more selective than compound <b>3b</b>. Both compounds presented better activity than phenstatin on T–47D breast cancer cells, with compound <b>3b</b> also being more active on SK–MEL–28 melanoma cells, while compound <b>5a</b> was more active than phenstatin on COLO 205 colon cancer cells. As for the probable mechanism of action, the benzoquinoline derivatives could act as PI5P4Kα and PI5P4Kβ inhibitors or topoisomerase II inhibitors. |
