The occurrence of 3D isostructurality in six halogensubstituted N-benzoyl-N-phenylbenzamides has been reported and this feature has been quantitatively analyzed in this study. 4-fluoro-N-(4-fluorobenzoyl) N-(fluorphenyl)benzamide (1) was observed to be isostructural with 2-fluoro-N-(2fluorobenzoyl) N-(4-fluorophenyl)benzamide (7), N-(4-bromophenyI)-2-fluoro-N-(2-fluorobenzoyl) benzamide (8) and 2

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
