In the present study, the genotoxicity risks of two 9-aryl substituted phenanthrene derivates synthesized as drug precursors were tested with Allium test. 9-(5-nitro-1H-benzimidazol-2-yl) phenanthren decreased the mitotic index (MI), and increased chromosome aberrations, among them C-metaphase, sticky metaphase, disturbed metaphase, lost chromosome at metaphase, polyploidy, disturbed anaphase, anaphase bridge, anaphase bridge with lost chromosome, chromosome break at anaphase and micronuclei formation. 9-(5-nitro-1H-benzimidazol-2-yl) phenanthrene has shown genotoxic effects, while 9-(phenanthro [9,10-d] imidazol-2-yl) phenanthrene had not any genotoxic effect.
