Four regioisomeric phenanthrene (PH) quinones (Q) were investigated for their ability to induce chromosomal damage and spindle disturbances. PH 1,4-Q and PH 1,2-Q induced structural as well as numerical chromosomal aberrations, whereas the isomers PH 9,10-Q and PH 3,4-Q were virtually inactive in this respect, However, all four compounds enhanced the frequency of c-mitoses.
