We investigated anti-cancer activity of mesogenic compounds possessing a hydroxyl group. The compounds were tested against A549 human lung adenocarcinoma cell line. Three ring heterocyclic derivatives containing a phenol unit showed significant suppression of the cell growth. The cell cycle analysis indicates that these compounds induce apoptosis. To determine the influence of these derivatives on normal cells, they were tested against WI-38 human lung fibroblast cell line under the same condition. Very interestingly, suppression of the normal cells was found to be dependent on the core structure of the mesogenic moiety. Some compounds induces apoptosis selectively against the tumor cell without suppressing the normal cell.
