An unpredicted condensation of naphthylamine with two molecules of ethyl propiolate yields directly carbethoxy benzoquinoline in high yield. Some benzoquinoline carboxamide derivatives with protonatable side chains were then synthesized and evaluated for antiproliferative activity on human tumor cell lines. The most active compound (7a) demonstrated to intercalate into DNA and to inhibit the relaxation
