the highest activity and was significantly more active than the 4-nitro positional isomer. The 5- and 6-nitro derivatives of 2-(4-methoxyphenyl) benzoxazole, 2-(4-methoxyphenyl)benzothiazole, and 2-(4-methoxyphenyl)indole were synthesized and their relative activity as topoisomerase Iinhibitors determined. None of these heterocyclic analogues were effective in significantly inhibiting cleavable-complex
