Popis: The activities of a series of acyclic enediynes, 2-(6-substituted hex-3-ene-1,5-diynyl)benzonitriles (1–5) and their derivatives 7–23 were evaluated against several solid tumor cell lines and topoisomerase I. Compounds 1–5 show selective cytotoxicity with Hepa cells, and 2-[6-phenylhex-3-ene-1,5-diynyl]benzonitrile (5) reveals the most-potent activity. Analogues 8–10 and 13–22 also have the same effect with DLD cells; 1-[(Z)-dec-3-ene-1,5-diynyl)-4-nitrobenzene 21 shows the highest activity among them. Moreover, 1-[(Z)-dec-3-ene-1,5-diynyl]-2-(trifluoromethyl)benzene (20) exhibits the strongest inhibitory activity with the Hela cell line. Derivatives 9, 10, 18, and 23 display inhibitory activities with topoisomerase I at 87 μM. The cell-cycle analysis of compound 5, which induces a significant blockage in S phase, indicates that these novel enediynes probably undergo other biological pathways leading to the cytotoxicity, except the inhibitory activity toward topoisomerase I.
