[Cancerostatic effect of some fluorenone azomethines tested against leukemia L 1210 (author's transl)].

Eight of fifteen Fluorenone-Azomethines without alkylating function have been found effective against the leukemia L 1210. Little modifications concerning the structure of the compounds caused loss of effectiveness. It seems remarkably that one corresponding derivative with a nitrogen mustard group (4) was ineffective. Correlations between chemical structure and biological effect have not yet been found.
