decreased significantly if a chlorine or methoxy group replaced the fluorine atom. 3'-Fluoro-6-methoxy-2-phenyl-4-quinolone-3-carboxylic acid (68) had the highest in vitro cytotoxic activity among all tested carboxylic acid derivatives and their salts. The mechanism of action may be similar, but not identical, to that of tubulin binding drugs, such as navelbine and taxol. Compound 68 merits further investigation

4′‐nitrophenyl sulfonate 10 m exhibit superior cytotoxicity over other sulfonates. The antiproliferativeactivities of these compounds correlate well with their abilities to induce mitotic arrest and apoptosis. Mechanistic studies indicate that they target the vinblastine binding site of tubulin and inhibit cellulartubulinpolymerization. Hence, these compounds induce the formation of aberrant mitotic spindles
